As the name suggests, the Govee Outdoor Projector Light is an outdoor-suitable projector, with smart capabilities allowing it to be controlled via the Govee Home app. It has a list price of $129.99 / £159.99 at Amazon, and is also available on the Govee UK website for a list price of £159.99, although at the time of writing Govee is offering Christmas deals, lowering the cost to £109.99. Presently, the Govee Outdoor Projector does not appear to be available on the US Govee website.
The Govee Outdoor Projector Light is a sizable 6.7 x 7.9 x 11.8 inches / 300 x 170 x 200 mm and weighs 4.4lb / 2kg. The majority of the projector is made from black plastic, which looks and feels a little on the cheap side, but it seems sturdy enough. The adjustment bolt worked well, allowing me to adjust the angle of the projection with ease, and the weight of the metal stand proved heavy enough that I could place it on the floor without it toppling.

Does the face of this projector look kind of like Wall-E going through his cyber-goth phase to anyone else? No? Just me, then. Moving swiftly on: the Govee Outdoor Projector Light is suitable for outdoor use thanks to the IP65-rated control box and IP44-rated adapter. There is the option to fix it to a metal base plate or a plastic ground stake to suit different requirements, and it can project up to 749 sq ft / 255 sq meters depending on the distance between the projector and the surface it’s projecting onto.
The Govee Outdoor Projector Light syncs up to the Govee Home app, which, if you’ve already read my review of the Govee Table Lamp 2, you’ll know I’m a big fan of. The app has a user-friendly and attractive interface, with easy-to-locate settings making it easy for me to customize effects. Within the app, there are a range of useful features including a timer and Matter, Alexa, and Google connectivity, so you won’t need to venture out into the cold to switch things up.

I spent a lot of time checking out the various settings to see how well they performed. First, I experimented by changing the colors of the Aurora, a projection of colorful waves, and the modes, with options like breathe and gradient available. The results were mixed, as I found that even if I only had pinks and purples in my color selection, there was always blue and green in the projection. I didn’t mind these colors, but I found it odd that these remained present, even when they weren’t in my chosen color palette. It was a shame that the AI bot insisted on adding the laser dots to anything it generated and, while there was the option to edit the result, this was limited to the colors of the aurora, so the bright green laser pattern remained.
Many of the preset scenes have the option of different speeds; on the fastest setting, the themed patterns appear and disappear quicker, and the colorful wave-like scenes move and change color at a faster pace. I couldn’t find a way to remove or alter the backgrounds of the themed patterns at first; I’d have liked to have the option to project the snowflake icons on their own. I explored the DIY and AI scene creators but sadly they don’t use these shapes; they only work with the colored lighting and the laser dots. I found the laser dots, which the Govee app refers to as stars, to be a little harsh on the eyes, but I was able to amend the brightness and color combination in the operations section, which made them a bit less of an eyesore.
(Image credit: Future)
Eventually, I found a way to project the themed patterns alone, although color choices were limited. Hidden within the operations tab, it was possible to change the projection of the default red, green, and blue laser dots. I assigned each color to show a snowflake and turned off the aurora set to play in the background, and voila, simple snowflakes. I did wish there was the option to select white or other colors though, as there is a somewhat cheap aesthetic about the colors when they appear together, although the remaining blue snowflakes after turning the red and green off looked nice enough. I also discovered I could turn off or adjust the orbit speed, so the icons would remain static or move slower, and I could also adjust the breathing speed to customize how long the projection stayed up before fading out during each cycle.

Overall, my experience of the Govee Outdoor Projector Light was underwhelming and frustrating at times. It can generate some nice, colorful lighting, so if you’re just looking for a smart light that’ll add a little pizazz to your outside space it’s fine, but if you’re looking for something that you can customize with ease and can project attractive patterns onto your home’s exterior, this likely isn’t the outdoor projector for you. We love testing smart lights here at TechRadar, so if you do too, I’d recommend checking out our pick of the best smart lights to see if anything takes your fancy.
Govee Outdoor Projector Light review: Price and specs
Should I buy the Govee Outdoor Projector Light?
Buy it if...
You want an outdoor projector you can control from your couch Thanks to its Wi-Fi and Matter connectivity, this outdoor projector is easy to control via the Govee Home app or smart home devices such as Alexa and Google Assistant.
You want to add a bit of color Despite my niggles with the sometimes glitchy and limited customization options, the Aurora projections are satisfyingly pretty to look at.
Don't buy it if...
You want sophisticated themed projections Although it may be capable of keeping the kids entertained for a moment, the themed patterns are a little simple and unimaginative. If you're thinking of showcasing minimal but high-quality snowflakes onto your house, you might want to think again.
You want to perfect your projections A surprising result considering the fantastic customizations available from other Govee products via the app, the settings for the Outdoor Projector aren't as intuitive, and projections often seem to have a mind of their own.
Govee Outdoor Projector Light review: Also consider
Govee Permanent Outdoor Lights 2 If you'd rather opt for a permanent fix that can be used all year round then these outdoor smart lights may catch your eye. Simple to install using 3M sticky pads and clips, these IP67 lights can be easily controlled via the Govee Home app, so you can change things up whenever you feel like it. Check out this article if you'd like to learn more about them.
How I tested the Govee Outdoor Projector Light
I tested the Govee Outdoor Projector Light for one week
I evaluated how easy it was to set up and sync with the Govee Home app
I tested the different features and customizable settings
I used the Govee Outdoor Projector Light to add some brightness and color to a white-washed cinderblock wall and in a darkened room.
I assessed the quality of the materials and how easy it was to put together.
I explored the various presets within the app, fine-tuning the projections by changing the settings of the presets and creating my own via various features in the app.
The Philips Hue Play Light Bar (sold individually, or in packs or two or three) is a lozenge-shaped smart light that creates a similar effect to a Philips Ambilight TV, extending the colors from the edges of your screen and washing the area behind with matching light to make your movies, TV shows, and games more immersive. They're flexible, easy to use, and a lot of fun.
The general impact is similar, but the Philips Hue Play Light Bars have some key advantages over both Ambilight TVs and the best Ambilight alternatives such as Nanoleaf 4D. First, you're not limited to positioning them directly behind your TV, although you can do that if you wish. You can also place them above, below, or to the sides, and you can position them quite far away if you have enough space.
This means you have a lot more flexibility when designing your lighting system. You can even use them together with a Hue Play Gradient Light Strip if you want to create a really dramatic home cinema experience with synced lighting that floods the entire room.
Color reproduction with the Philips Hue Play Bars is excellent, even with subtle tones (Image credit: Future)
The Hue Play Bars connect wirelessly to a Philips Hue Play HDMI Sync Box, which means they don't suffer the same problems as lighting systems such as Nanolead 4D that use a camera to monitor and reproduce the colors on your screen. There's none of the lag you might get with a camera-based system, and they're not affected by reflections.
In fact, color reproduction is super impressive – as you can see in the image below, where the bar on the left has reproduced the exact shade on the tablecloth, and the one on the right has taken more of an average value factoring in the gray color of the presenter's sleeve.
They also reproduce natural shades and skin tones very well, and colors shift smoothly, which avoids creating a distraction.
Connecting to your TV via HDMI means there are none of the issues you can experience with kits that use a camera to monitor and replicate colors from the screen (Image credit: Future)
Each light has a plastic stand that allows you to position it vertically or horizontally using a hex screwdriver or Allen wrench. You can also mount them on the wall using adhesive pads; however, if you do this, you'll probably want to hide the cables using trunking or by running them through the wall. The lights connect to the Sync Box wirelessly, but they're not battery-powered.
The Light Bars are available in black and white, so you can choose whichever blends in best with your decor. My borrowed review units were black, but if I was buying them for my own home, white would be the better option.
The lights come with mounts that let you position them horizontally or vertically, but you can also attach them to the wall, the back of your TV, or just lie them down on a shelf or TV stand (Image credit: Future)
The main disadvantage of the Philips Hue Play Bars is that they require a Philips Hue Bridge to control them via the mobile app, plus a Philips Hue Play HDMI Sync Box for synchronizing lighting with your TV, which adds to the price substantially if you don't already own them. The Bridge costs around $60 / £60 / AU$75 if bought alone, and Sync Boxes start at $250 / $230 / AU$500 for the 4K version. The Philips Hue Play HDMI Sync Box 8K released in 2024 costs even more.
Without these, you'll only be able to use the Play Bars as you would any ordinary lights via the Philips Hue Bluetooth app. This will let you turn them on and off, and change their color manually, but nothing else.
If you have the Bridge and Sync Box, setting up the bars in the Philips Hue app is a piece of cake. Just plug in the power supply (which supports up to three Play Bar lights), set the Hue app to search for them, and they will be identified automatically, ready to be added to your room.
When you're not using your TV, you can use the Play Bars like any other Hue lamp, setting their colors individually, or incorporating them into Scenes. When it's time to enjoy a movie or game, just tap the Sync button in the app.
The Light Bars come in black and white, so you can choose whichever fits best with your decor (white would have been a better match here) (Image credit: Future)
For those who already have a Hue setup, the Play Bars are a versatile and fun addition that can make your home cinema setup even more immersive. They're not the best entry point into the Hue system, since you'll only get the full experience with the Hue Bridge and Sync Box, but if you want to expand an existing system, they're a great option.
Philips Hue Play Light Bar: specs
Philips Hue Play Light Bar: price and availability
The Philips Hue Play Light Bar is available individually, or in packs of two or three. As with most Philips Hue products, you can also find them bundled with other lights and accessories, such as the Hue Bridge, which may be significantly cheaper than buying each component separately.
The Sync Box is the most expensive part of a Philips Hue Play setup. If you already have one (and a Play Gradient Light Strip) then the Light Bars are a pretty reasonably priced addition that will really give your home cinema a wow-factor.
You want a totally flexible lighting system
The beauty of the Light Bars (other than their excellent color accuracy) is that you can position them pretty much anywhere, allowing you to adapt your lighting setup to suit your home.
Don't buy it if
You don't have any Philips Hue products already
Unless you really love the idea of the Play Light Bars (which you might), this will be an expensive entry into the Hue ecosystem. The lights themselves might not break the bank, but the HDMI Sync Box is a serious investment, particularly if you want the 8K model.
Philips Hue Play Light Bar: also consider
Not sure about the Philips Hue Play Light Bar? Here are two other ambient lighting options that are worth considering.
Nanoleaf 4D
Nanoleaf 4D is one of the most affordable alternatives to Philips Ambilight, and at CES 2025 the company announced a new version of the system that doesn't require fitting awkward corner brackets to your TV.
Govee's budget-friendly lighting system does a good job in dark conditions, although its camera will pick up light from any source near your TV, not just the screen itself, so daytime viewing isn't as good.
I tested a pair of Philips Hue Play Light Bars, using them as part of a larger Hue lighting system including ceiling-fitted bulbs, an HDMI Sync Box, and Hue Bridge. I used them to sync content from my TV, and as standalone smart lights that I controlled via the Google Home app.
I used the lights with a wide variety of media, but to avoid copyright infringement, all the images in this review show videos from TechRadar's own YouTube channel.
The robot vacuum on review here is the Yeedi M12 Ultra Plus. Elsewhere in the lineup you'll find the Yeedi M12 Pro Plus – this is essentially the same vacuum, but the Ultra Plus has marginally higher suction: 11,800Pa for the Ultra, 11,000Pa for the Pro Plus.
The Yeedi M12 Ultra Plus is a fantastic robot vacuum in terms of cleaning power. The vacuuming is powerful (with suction specs up there with the highest on the market) and reliable, the mopping is efficient – especially thanks to a pad that can shift outwards to enable this robovac to mop right up to the edges of rooms. Reliable object avoidance and very good mapping also help ensure a thorough clean.
In fact, in terms of cleaning alone, it's up there with the best robot vacuums on the market. However, it doesn't quite set itself apart in a way that's much of a game-changer, and it lacks extra features that you will find with other premium models. Perhaps the most notable of those is the lack of voice assistant support (which is surprising at this price point), but you also can't do things like use the bot as a security camera / pet checker. To some, those features will be unnecessary extras, though.
The base station is comprehensive, taking care of much of the maintenance for you, including refilling the bot's water tanks, and washing and drying the mop pads. However, the knock-on of that is that it is quite bulky.
That's the short version; read on for my full Yeedi M12 Ultra Plus robot vacuum review.

Yeedi M12 Ultra Plus review: price & availability
List price: $1,099 / (about £840 / AU$1,630)
Available: US
Launched: September 2024
An asking price of $1,099 / (about £840 / AU$1,630) may seem exorbitant, but it really isn't with flagship models such as the Yeedi M12 Ultra Plus. Top-of-the-line models basically start at around $1,000 / £1,000 so something that's just a hundred bucks more is reasonable. Add on to that the fact that the Yeedi M21 Ultra Plus comes with powerful suction rated at 11,8000 Pa and has an extendable mop pad for mopping edges, along with great object avoidance, and you're getting pretty good value. While I hesitate to call it a deal, it's worth the price.
Compare, for instance, to the Narwal Freo X Ultra. At $1,399.99 / AU$ 2,299 (about £1,110), it's quite a bit more expensive, doesn't have that extendable mop pad, and isn't quite as powerful(it has 8,200 Pa of suction). The Narwal is a bit more aesthetically pleasing, however, and more feature-filled. For instance, you can actually use it as a security video camera drone.
The Ecovacs Deebot T30S Combo is another option that's going to set you back quite a bit with its $1,199.99 / AU$2,299 (about £950) price tag. It's very feature-rich and even comes with a handheld vacuum that self-empties into the base station. While it shouldn't be a huge consideration since all of these robot vacuums frequently return to the base station to wash their mop pads, it does have a 200 minute battery life to the Yeedi M12 Ultra Plus' 290 minutes.
Value for money score: 4 out of 5
Yeedi M12 Ultra Plus specs
Yeedi M12 Ultra Plus review: design
Spinning mop pads – one of which extends to reach the edges of rooms
3D mapping sensors for improved object avoidance
Large water tanks and dust bag in base station
The Yeedi M12 Ultra Plus, as a flagship robot vacuum, comes with some top tier design choices. For instance, while it comes with just one side brush (some models have two), it does have an anti-tangle brush roll. Plus, it comes with two spinning mop pads, one of which can extend out for edge mopping. Both can also lift off the ground for carpet cleaning as well, though it's not quite high enough for thick, shag carpets.
(Image credit: Future)
As far as its sensors go, it utilizes 3D mapping – you can see the results in the app. When it goes around mapping or cleaning, you can actually see two lasers cross in front of it. This helps with seeing objects more fully to avoid them. (Here's more on how robot vacuums navigate, if you're interested.)
(Image credit: Future)
Moving on to the base station. This is on the bulky side, although that's common for docks that offer comprehensive maintenance features, as this one does. Not only will it empty the bot's dustbin, it can also refill its onboard water tank and clean and dry its mop pads.
The most unusual thing about the dock is the fact that the clean and dirty water tanks are flat and wide, sitting on top of the base station instead of the thinner, deeper tanks of other models that sit inside the base station. I'm not sure there's a real practical difference other than the water tanks here are harder to tip over if you're filling up or emptying them.
They're both sizable, with the clean water tank holding 4L and the dirty water tank 3.5L. The dust bag that the robot vacuum automatically self-empties into is also pretty big at 3.4L. Also on hand are features that I've come to expect in flagship robot vacuums with mopping capability, such as hot mop pad washing and drying.
Design score: 5 out of 5
Yeedi M12 Ultra Plus review: performance
Both vacuuming and mopping are great
Extendable mop pad means edges get mopped
Object avoidance is very good
As one would expect with a flagship model, the vacuuming and mopping are both very good with the Yeedi M12 Ultra Plus. I tested this robot vacuum on hardwood and marble floors as well as a bath mat to see how it would do with carpeting.
Tackling the vacuuming first, it sucked up all manner of debris very well. For a more controlled test, I used cereal and sugar and it sucked everything right up. That's to be expected for a robovac that boasts 11,800Pa of suction – right up there with the highest on the market.

If there's any place to mildly criticize the M12 Ultra Plus, it would be nice to see two side brushes instead of just one, as this would push more dust and debris in front of it to pick up per pass. At least it has a tangle-free brush roll.
While I was impressed with the mopping as well, it's a bit light on how much water it uses so I ended up preferring to use the highest water level when running it. Still, it left floors looking very clean. During that cereal and sugar test, I also tossed some coffee on the floor and it mopped that up fairly quickly.
(Image credit: Future)
Also, one of the mop pads extends out during cleaning so that the Yeedi M12 Ultra Plus is able to get to the edges of rooms. It's a nice feature that not all flagship robot vacuums come with.
Since the mop pads can lift up, when it vacuumed the bath mat that I used to simulate testing on carpet, it left the bath mat dry, meaning you can use this robot vacuum in a hybrid space and it will vacuum and mop hard flooring while just vacuuming carpeted areas.
Since this robot vacuum utilizes its 3D sensors for navigating and mapping, it does a very good job avoiding objects. I saw it go right up to and around chairs that had been moved, without touching (or sometimes barely touching). Just be aware that Yeedi hasn't yet solved cables and cords (no one has, frankly) so you should still pick those up before running the robot vacuum.
Performance-related features also include mop pad washing and drying as well as auto-emptying. They all work very well, though the robot vacuum has a tendency to wash the mop pads before running, which can be annoying if something just spilled and you want to do some spot cleaning.
Battery life
Since the Yeedi M12 Ultra Plus is one of those robot vacuums that regularly returns to its base station to wash its mop pads and empty its onboard dustbin, squeezing every minute of battery life out of it is not going to make a big impact on your experience. Still, its up to 290 minutes of use is fairly remarkable as many robot vacuums, especially with spinning mop pads, have a battery life that's closer to 200 minutes.
Performance score: 4.5 out of 5
Yeedi M12 Ultra Plus review: app
Straightforward to use
Somewhat light on features – no option of voice assistant support
Mapping is mostly good
The app is straightforward, from setup to use. There are no surprises, though some of that is due to the fact that there aren't a lot of extra features here. You won't find the ability to pair with Alexa or use as a remote video drone (this may seem random but more than a few flagship models have this feature).
But, the more important stuff is here, such as running the Yeedi M12 Ultra Plus in vacuum only, mop only, or vacuum and mop mode and the various settings during its cleaning (vacuuming power, mopping water level, etc.). There's also the ability to schedule cleanings, see a log of previous cleanings, edit the map, and adjust some other settings.
I like to focus specifically on the maps as I typically test robot vacuums in a semi-open floor plan and find many to have issues dividing the mapped space into smaller rooms – typically, the whole space, which comprises four rooms, are registered as one big room.
The Yeedi app does a good job dividing that space into smaller rooms, though I did find one instance where it wouldn't accept a division, so I have to either clean two rooms at once or use the zone setting to clean one of those specific rooms. This is an improvement over what I've experienced in the past, not just from Yeedi but other manufacturers as well.
App score: 4 out of 5
Should you buy the Yeedi M12 Ultra Plus?
Design
Sizable water tanks and dust bag in the base station, and the robot vacuum has an extendable mop pad.
5 /5
Performance
Vacuuming and mopping performance are both very good.
4.5 /5
Buy it if...
You want great vacuuming and mopping
There's little to fault with its vacuuming and mopping performance. Plus, it can get to the edges with that extendable mop pad.
You have an open or semi-open floor plan
Its mapping and ability to divide the map in app makes creating new rooms easy, though there are still some quirks.
You want good object avoidance
Maybe it's from that 3D mapping, but the object avoidance is very good, without giving too wide a berth to the objects the robot vacuum is avoiding.
Don't buy it if...
You're on a budget
The price is reasonable compared to other flagship models, but you're dropping quite a bit of cash here.
You want all the bells and whistles
It has all the necessities on hand, but there are a few extras that other flagship models offer that you won't find with this Yeedi – lack of voice assistant support being the main one.
Yeedi M12 Ultra Plus: alternatives to consider
Narwal Freo X Ultra
The Narwal Freo X Ultra sets itself apart just by its base station's aesthetics, with its more aerodynamic look. It's feature-filled and good at vacuuming corners, but is very pricey, has some minor issues with mapping (at least with open floor plans), and is not quite as powerful as the Yeedi M12 Ultra Plus.
It might be louder and more expensive, but the Ecovacs Deebot T30S Combo is worthy competition to the Yeedi M21 Ultra Plus. Not only does it do a great job vacuuming and mopping – it has that same extendable mop pad to get edges – but it also comes with a handheld vacuum for some extra deep or spot cleaning prowess.
To test the Yeedi M12 Ultra Plus, I used it for a week to vacuum and mop the hardwood floors and a bath mat (to simulate carpeting) in my house. I also tested all the features listed in the app, particularly its mapping. I took note of how well the vacuum cleaned the edges of a room as well as around obstacles.
GE Cync Lighting Dynamic Effects Smart Bulb: two-minute review
The GE Cync Lighting Dynamic Effects Smart Bulbs are a fantastic addition for anyone looking to add some smart and (per the name) dynamic lighting to their smart homes. While GE offers all sorts of different lighting options, the smart bulbs comes in two versions: A19 and B30. The first, reviewed here, fits into most traditional light fixtures, while the B30 is ideal for recessed lighting.
You don’t need a hub for the GE Cync Lighting Dynamic Effects Smart Bulbs, so adding them into a smart home is pretty straightforward. That said, they are limited to certain ecosystems – a minor travesty in this day and age where Matter certification is becoming more widely adopted.
Overall though, the GE Cync Lighting Dynamic Effects Smart Bulbs belong in the conversation for the best smart lights due to, not only their easy implementation, but the wide range of colors and effects on offer.
The A19 bulbs fit most standard light fixtures (Image credit: James Holland)
Physically, the GE Cync Lighting Dynamic Effects Smart Bulbs look like most smart bulbs in that they keep the same basic shape of the bulb form factor. The outer part of the bulb is an opaque white while the lower portion towards the base is covered in a matte white casing presumably covering the more digital components of the bulb.
The A19 version reviewed here is on par with a 60 watt light bulb ,offering 800 lumens in terms of brightness with a color temperature of 2,700k. Since this is a bulb with a focus on dynamic lighting, there are 16 million colors and white tones available, and the brightness can be fully adjusted.
The GY Cync Lighting Dynamic Effects Smart Bulbs offer 16 million colors to choose from, and different temperatures of white light (Image credit: James Holland)
Likewise, pairing the light bulb is very easy and straightforward, consisting of physically installing the bulb, turning on the lamp, and going through the setup prompts on the Cync app. Having dealt with a number of smart bulbs over the years, I have found that cheaper ones (aka budget brands) can have connectivity issues during pairing and sometimes even during use.
The GE Cync Lighting Dynamic Effects bulb might be a little spendy compared to other models, but its connectivity is rock solid. In fact, the closest I‘ve had to any issue is a second or two of lag when turning off through the app, but that’s only if the light’s been on for a while.
Setting up the bulbs using the mobile app is refreshingly straightforward (Image credit: James Holland)
I also tested it with Alexa The setup took just a few steps, and Alexa responded quickly to my voice commands. Unfortunately, this smart bulb only has access to Google Home and Alexa. While that accounts for a good number of smart home ecosystems, it leaves plenty of people in the cold, something that Matter certification would help with, and which isn't on offer here. What’s surprising is that GE does have some Matter-supported bulbs, such as in the reveal and direct connect models.
The GE Cycle Lighting Dynamic Effects Smart Bulbs work with Alexa and Google Assistant, but not Apple HomeKit (Image credit: James Holland)
Most of the magic for this smart bulb is accessible via the app. Each installed light bulb shows up as its own entry in the app, and shows up as a boxy tile with an on/off toggle and a slider to adjust brightness. Tapping the tile doesn’t open more menu diving as one would expect. Instead, you’ll end up turning the light on or off depending on its current setting.
To dig deeper, there’s a little inward pointing arrow at the edge of the icon that, when pressed, moves the tile to the side to reveal four smaller icons. The first gives access to a color wheel where you can really fine-tune the color you want. If there aren’t 16 million colors available here, then it’s probably close. There are some other options in this section of the app where you can just select some preset lighting including different shades of white and some basic colors.
The app allows you to set a color for the whole bulbs, or divide it into sections (Image credit: James Holland)
I won’t say shame on you if you stick to these settings, but you’re missing out on what this light bulb can do if you don’t go beyond that. The second of the four smaller icons allows you to subdivide the lightbulb into four differently colored sections for when you want to get a little wild, but still want static lighting.
The third icon is probably the most unique to the GE Cync Lighting Dynamic Effects Smart Bulb as this is where the actual dynamic effects are available. First, it should be noted that the dynamic effects are subdivided into two sections of effects, selectable by pressing on ‘light shows’ or ‘music shows’ at the bottom.
Whichever is selected will show a number of presets already loaded onto the bulb, as well as a section of other presets to explore and preview that can be downloaded as well. All the dynamic effects can be customized, though the level of customization depends on the effect itself. Usually, you can change the brightness and selected colors used (many of the presets cycle through different colors for their effects) at the minimum.
The bulb's 'light shows' are a fun addition, and all dynamic effects are customizable (Image credit: James Holland)
The light shows are fun, but are a bit more static than the music shows, which use the microphone on your smartphone (and you can select the sensitivity) to respond to aural stimulus. It’s really cool to see the smart bulb change color and intensity according to the dynamics of a song. The only minor issue is that it responds much better with the volume up. So, when I have a music show effect loaded and am listening to music at a comfortable level that one could talk over, the effect only seems to respond to the peaks of the audio and is off otherwise. To get the full experience, I have to turn up. While cool, I have to consider my neighbors when choosing to turn it up.
Lastly, the fourth icon is for settings. While I won’t spend too much time on this, it’s worth mentioning that there’s a feature here called ‘Trueimage’ that lets you take a picture to set as the background of the smart bulb tile, and preview changes even if you're not in the same room.
TrueImage is a tool that lets you preview changes to the color of your smart bulbs even when you're in a different room (Image credit: James Holland)
The Cync Lighting Dynamic Effects Smart Bulb looks great, whether on a white light setting – regardless of the warmth (I do like to go warmer) – or one of the dynamic effects with its full color array.
Really, the only shortcomings of this light bulb is the lack of Matter support. While somewhat expensive on a per-bulb basis, it’s not an unreasonable price. And, the dynamic effects are worth the cost.

GE Cync Lighting Dynamic Effects Smart Bulb: price and availability
Prices start at $19.99 (about £20 / AU$40)
Available now
Available in the US and Canada
Getting a two-pack of the A19 size direct from GE will run you $37.99, while a single bulb costs $19.99 MSRP. Their availability is limited to the US and Canada, as they unfortunately do not work in the UK or Australia. The B30 is priced very similarly with a single bulb, though it’s listed at a range from around $17 to $26 depending on the retailer.
Pricewise, the GE Cync Lighting Dynamic Effects Smart Bulbs are a little on the higher end, considering that a two-pack of the Govee Wi-Fi LED Bulb goes for $23.99 / £23.39. Of course, there are some trade-offs, particularly the fact that the Govee’s brightness and the app design could be better.
However, $20 a bulb is not an inappropriate price point. Nanoleaf Matter Essentials costs $19.99 / £19.99 / AU$39.99 for an A19 bulb. While Nanoleaf’s app is a bit buggy compared to the rock-solid setup of the GE Cync, it does come with Matter certification is more universal in application.
Should you buy the GE Cync Lighting Dynamic Effects Smart Bulb?
Buy it if
You want dynamic effects
The dynamic effects available here are a treat, especially the ones that respond to audio, and set it apart from the competition. Get enough of these and you could probably throw your own rave.
You want easy connectivity
This smart bulb is incredibly easy to set up and use, not to mention that its connectivity is rock solid.
Don't buy it if
You don’t want to spend too much
At about $20 per bulb, the GE Cync Lighting Dynamic Effects Smart Bulb is on the pricier end. If you’re trying to stretch your budget (maybe you’re trying to get a bunch of bulbs), there are plenty of smart bulbs that are much more affordable.
GE Cync Lighting Dynamic Effects Smart Bulb: also consider
Govee Wi-Fi LED Bulb
If you’re on a budget, the Govee Wi-Fi LED Bulb might be the way to go. Sure, the colors could be a little brighter and the app could be better designed, but you can get two Govee bulbs for almost the price of one GE Cync smart bulb. The Govee likewise supports Google Home and Alexa.
The Nanoleaf Matter Essentials might need a hub for Apple HomeKit, but it's Matter-certified, meaning that you can use it with any smart home ecosystem. If you have something outside of Google Home or Alexa, that immediately puts it above the GE Cync bulbs. On the flip side, their setup is not quite as rock solid as the GE Cync’s.
How I tested the GE Cync Lighting Dynamic Effects Smart Bulbs
Tested over a couple weeks
Tested all the different features including multiple dynamic effects
Used with a voice assistant
I spent a couple weeks using the GE Cync Lighting Dynamic Effects Smart Bulbs to get an idea of how they function against how they’re advertised and to see if they’re worth the price. I tested the various presets, from static colors to various dynamic effects. I even connected it with Alexa to see how it would work with a voice assistant.
After having tested the GE Cync Lighting Dynamic Smart Bulbs, I found them to be ideal for those who want a little extra from smart lighting, particularly those engrossing dynamic effects.
I’ve spent the last few years reviewing all sorts of gadgets from audio equipment and robot vacuums to laptops and more with a detailed eye on whether the product works as advertised and is beneficial to those who might be interested in it. For more details, see how we test, rate, and review at TechRadar.
Dreame Technologies hasn’t been around long but, since its inception in 2017, the brand has made some excellent robot vacuums, including the Dreame L20 Ultra. The X40 Ultra succeeds the older model (as well as the X30 Ultra), bringing much-improved intelligence and tracking compared to lesser bots, as well as a fairly unique collection of features. For those who want something slightly cheaper, it's well worth checking out our Dreame L40 Ultra review.
Like most robovacs, the X40 Ultra handles both vacuuming and mopping and comes with a base station that empties the robovac’s dustbin, dispenses water, and cleans the mopping system. Where it stands out is the ability to leave the mop pads behind when vacuuming, the automatic dispensing of floor-cleaning fluid, the wide array of sensors, and the ability to recognize a large number of objects using its cameras.
Getting the X40 Ultra up and running is relatively simple, and upon first activation, it will map your home with an array of sensors. The test space for this review was my own home with a built-in area of 80 sqm, and it took the bot about 10 minutes to poke its robotic nose into every room. The quality of the resulting map is excellent, and any adjustments are easy to make within the Dreamehome app. The X40 is great at identifying and avoiding obstacles like shoes or cables and can even recognize your pets and give them space when cleaning. While very functional overall, the app can be a little clunky at times, like lack of consistency in how navigation gestures work, and a convoluted layout to reach certain settings.
If activating a scheduled or single-time clean, selecting CleanGenius mode lets the robovac use its own smarts to decide exactly what is needed, and it will vacuum, mop, and go back over areas as it sees fit. While the results were good, I found the robovac went a bit overboard and wanted to mop my polished wooden floors every day. Instead, I set a schedule for a daily vacuum and reduced mopping to once a week. I also configured shortcuts in the app to trigger custom cleanups, like an extra vacuum or mop by the front or back door for when my dog walked in with muddy paws.
The X40 Ultra is equipped with an extendable and liftable side brush for getting into corners and under furniture, plus dual spinning mop pads – one of which can also protrude further out as needed. The mop pads are magnetically attached, so the bot can leave them behind at the base station when vacuuming carpets, avoiding any chance of spreading damp mop water or contamination.

After three months of daily use, it’s hard to find fault with the vacuuming prowess of the X40. It works equally well on hard floors, carpets, or rugs, and the extendable brush does a great job of getting into corners and cleaning debris from along walls. The spinning extendable mops are likewise very effective, and the X40 Ultra can keep your floors shiny or quickly get rid of sticky messes. It also very thoroughly cleans the mop pads with hot water – then dries them with hot air – to avoid odors. Overall, the wearing parts on the X40 Ultra (like the mop pads, filters, and corner brush) are fairly robust and don’t need to be replaced too often.
Importantly, it has pet feces detection – and it really does work – which allows the robovac to spot and avoid any accidents, ensuring you won’t come home to a horror show of smeared messes. It can also detect wet patches, so it won’t spread or vacuum over any puddles it encounters.
As great as the robot itself is, the suction on the auto-empty station is a bit weak. I found I had to change the bag more often than expected – and these can get quite expensive. The X40 Ultra itself is not cheap – it’s one of the more expensive models on the market – but when you compare the actual technology and features included, it provides decent value overall.

Dreame X40 Ultra review: Price and availability
How much does it cost? Starting from $1,899 / £1,299 / AU$2,799
When is it available? Available to buy now
Where can you get it? You can get it in the US, UK, and Australia
The Dreame X40 Ultra was announced in May 2024 and can be bought directly from the Dreame website if your country has a local online storefront or from authorized local retailers, which can include Amazon. It has a rather steep asking price of $1,899 / £1,299 / AU$2,799 and, so far, has only attracted modest discounts. That said, it shouldn’t be too long before we start seeing worthwhile discounts, which would make the X40 Ultra worth investing in if you want a complete and autonomous cleaning solution for your floors.
However, using the X40 Ultra will incur ongoing costs, specifically the replaceable dust bags. I’ve included the accessories pricing below for the US, UK, and Australia. Notably the Dreame website doesn’t sell the side brush in the US, or the brush cover in Australia. You can also get a kit that contains 2x dust bags, 2x dust filters, 1x main brush, 2x side brushes, 6x mop pads – rather useless ratios of these consumables as they don’t match the usage rates.
For households like mine that have people (or pets) with long hair, Dreame sells an optional TriCut brush that’s designed to shred hair and avoid tangles and clogs. This upgrade does a much better job at keeping hair from tangling compared to the standard brush, and I think it’s well worth the added $49.99 / £49.99 / AU$199.95 – though Aussie buyers pay a very steep premium compared to the US and UK.
If you don’t need all the features offered by the X40 Ultra, or have a simple home layout with few obstacles, then a cheaper robovac like the Dreame L10s Ultra or D10 Plus may be a better buy. You can also opt for options from Ecovacs, with some models like the Ecovacs Deebot N10 Plus ($649.99 / £499 / AU$999) and Ecovacs DEEBOT T20 Omni ($1,099.99 / £951.65 / AU$1,799) offering good value for money.
The X40 Ultra has a fairly standard design and complements the typical round robovac form factor with a base station for charging, dustbin emptying, floor-cleaner dispensing, mop washing and drying – plus containers for clean and dirty mop water. In the box, you get the robovac itself (including mop pads), the base station, two dust bags, a cleaning tool, and 200ml (6.7 ounces) of floor-cleaning solution. Setting it up is very easy – the base station needs the ramp attached, but otherwise, it’s ready to go once plugged in and charged. After installing the app, you scan a QR code on the robovac, and it walks you through the rest of the process in just a few minutes.
The base station is tall (60cm / 24-inches) but relatively skinny (35cm / 14-inches) and only needs 5cm (2 inches) of clearance on each side. The dust bag and floor cleaner dispenser are hidden under a front-opening cover on the dock, while the mop water is accessed from under a hatch on the top – meaning it’s not suited for placement under a bench. Dreame will also soon release an optional kit to allow the base station to be plumbed into a fresh-water supply and a waste-water outlet, enabling the mop water changes to be fully automatic. The availability of this kit is to be confirmed.

The robovac sports a multitude of sensors to help navigate your home, ensure the best clean, and avoid any pets or places where it could get stuck. The front of the bot has two cameras (one infrared), as well as 3D Dual-Line Laser sensors and LED headlights. The underside has a carpet sensor, along with downward-facing cliff sensors to detect steps or other drops. The sides of the robovac have edge sensors, and on top, it features a microphone and a laser distance sensor (LDS). All these work together to allow the bot to recognize over 120 different types of objects – including obstacles like cables that could cause a tangle when vacuuming.
The X40 Ultra offers four suction levels – Quiet, Standard, Turbo, Max, and Max+ – with up to a very high 12,000Pa of pull. Notably, the highest suction level (Max+) is only available for a one-off clean and can’t be used with a schedule or a customized shortcut clean. This means the full advertised suction (up from the X30 Ultra’s 8,300Pa) feels like marketing spin, rather than an actually useful upgrade.
The robovac can extend its side brush to get deep into corners, clean along edges or under the lip of low furniture – and even lift it to avoid spreading liquids. The bot can also magnetically drop and pick up the mop pads from the base station, giving it extra cleaning flexibility. While the bot can lift the pads when vacuuming carpet, the clearance is 10.5mm (0.4 inches), so for deeper carpet piles or rugs, leaving the mop pads behind ensures there’s no chance of dampness or cross-contamination. The right-hand side mop pad is also extendable – meaning the X40 Ultra can reach into corners, mop along the edges of kitchen cabinets, or even clean a little way under the edge of low appliances like a fridge.
Design score: 4 / 5
Dreame X40 Ultra review: Performance
Somewhat noisy at full power
Amazing obstacle recognition
Weak base station automatic emptying
Overall, the X40 Ultra does a very thorough job of vacuuming and mopping – and aside from picking up larger debris by hand and the occasional spot clean, I didn’t have to do any extra floor cleaning myself. The robovac has a CleanGenius mode that lets it choose the cleaning parameters for you – though I found it mopped much too frequently, and I preferred using the scheduled cleaning function (as well as shortcuts) to create my own customized cleaning regime.
The X40 Ultra isn’t especially fast, and during my testing, it took around 1 minute per square meter when vacuuming, and takes about the same amount of time to mop. That said, it can vacuum and mop at the same time if needed, which allows for a quicker cleaning run. The 6,400mAh battery is rated to provide up to 198 minutes of vacuuming and mopping at Standard suction strength, covering up to an area of 308m² (3,315ft²) in Quiet mode. It’s a little frustrating that Dreame rates the runtime and area coverage at different vacuum power levels – the exact amount of coverage per charge depends on your specific home and cleaning settings. During my testing, the X40 Ultra was able to vacuum my small 80m² two-bedroom home at Max suction level, then do a full mop, and still have 80% charge remaining. Extrapolating from that, I think it will have no trouble cleaning up to 200m² per charge.
Overall performance score: 4 / 5
Mapping and obstacle avoidance
After setup, the X40 created a very accurate map of my home – with no adjustments needed in the app aside from giving rooms specific names. When vacuuming, the array of sensors and cameras does a great job of spotting anything on the floor, and it’s especially careful to stay clear of anything that might cause a tangle – like shoelaces or cords. Handily, the bot records a picture (viewable in the app) of any obstacle it encounters, making it easy to move it before the next clean.
The X40 Ultra has the smarts to recognize your pets (in my case, just the paws of a Great Dane) and will keep clear if it spots them snoozing. It records a few pictures of any interactions – viewable in the cleaning log via the app – so you can see how your pet reacts to the vacuum. It’s also possible to set up zones for the robovac to stay out of, like around a pet's bed or feeding area. Even more importantly, the robovac can recognize any pet droppings and will steer well clear when cleaning. My dog doesn’t make any messes at home, so I faked a test using food, and the X40 Ultra had no trouble identifying the fake feces and dutifully stayed well clear.

Using the app, you can also stream live video from the robovac’s main camera while it’s working, or take over and remotely steer it – though this can be a bit laggy. You can also command the bot to navigate to a specific spot in your home, use it to have a two-way conversation, or even have it automatically search for your pets and snap a picture.
Impressively, the robovac only got stuck twice in three months of testing – and both times were my fault. The first time was because it half-ingested a USB-C cable I had knocked down next to the base station, and the second was from vacuuming up a loose tile in my (very old) bathroom. In both cases, no damage was caused, as the bot knew it was stuck and waited patiently until freed.
Overall, the X40 Ultra did an amazing job of navigating my home and had no problem cleaning around always-changing obstacles – big and small – left in its way. It’s a great choice for anyone with a busy, complex home, or if you don’t want to have to worry about picking every last thing up from the floor before cleaning.
Mapping and obstacle avoidance score: 4.5 / 5
Vacuuming
I tested the X40 on polished wooden floors, as well as tiles and rugs. Aside from vacuuming every day for three months, I also performed a number of specific tests to gauge how effective the robovac is at cleaning up a variety of spills and debris types. I used flour, sand, rice, oats, dry dog food, and some dry leaves – scattered in a corner on hard floors and then on a short-pile rug.
Whether on carpet or hard floors, the flour, rice, oats, and leaves were 90% (or more) cleaned up after one pass – and fully gone after two. The dry dog food was all sucked up in one go, while the sand took three passes to capture it all (although a few grains remained on the rug). Importantly, the X40 Ultra’s side brush is relatively slow-spinning, so it doesn’t tend to flick any material away from the vacuum. Anything larger than about 10mm x 8mm (0.4 inches x 0.3 inches) will generally be recognized and avoided by the robovac, as it could get stuck behind the main brush.
I found that the standard vacuum level is fine for picking up pet fur, dust, and light debris on hard floors – but needs to be bumped up to Turbo or Max for carpets. The higher suction modes were also best for sand, heavier dirt, or chunkier debris like oats and dry dog food. This means a daily vacuum in the standard mode with a single pass will capture almost all the lighter debris in your home, but may leave a small amount of heavier debris behind. This isn’t much of a problem, as you can customize scheduled cleans on a room-by-room basis to accommodate different needs.

On lower suction levels, the sound isn’t too intrusive – and could be set to vacuum overnight – but with the suction turned up, the noise level is not far off a stick vacuum. Measuring at 1 meter (3.3 feet) with a decibel meter, the bot produced 43 dB on Quiet, 46 dB on Standard, 51 dB on Turbo, 55 dB on Max, and 60 dB on Max+. When the robovac is driving without vacuuming, it produces 41 dB, while mopping sits at 35 dB most of the time – with occasional peaks up to 45 dB when moving fast. The base station emptying the robovac dustbin hits 57 dB, while mop washing is 33 dB with peaks up to 50 dB when the water pump runs. These results are normal, but not particularly quiet – so you'll want to position the base station away from living areas where you relax or watch TV.
My home has two people who shed a lot of long hair, and in my testing, the side brush stayed relatively tangle-free – as did the main wheels and mop pads. The front roller does slowly collect hair – as does the main brush – though the TriCut brush (which is available to buy separately) is much better in this regard. Thankfully, both these areas are very easy to maintain, and the X40 Ultra’s design keeps the hair from getting sucked deeper into the inaccessible innards of the robovac.
Vacuuming score: 4.5 / 5
Mopping
I’m not a frequent mopper at the best of times, so I started my X40 Ultra’s testing with a deep clean – then reduced the mopping frequency to once a week – and my floors have never looked better! I found it handy to turn on an extra mopping schedule during wet weather, so areas near the front and back door were kept clean of muddy shoe and paw prints.
Like its side brush, the X40 Ultra can also extend the mop pad on the right side, and I found the robovac easily cleaned areas where a handheld mop struggled to reach. The automatically dispensed cleaning solution (a bottle is supplied in the box) also helped cut through grime in a way that robovacs using plain water can’t manage.
To further test the mopping ability, I spilled two puddles of soy sauce – one of which I allowed to dry – and also smeared wasabi paste and sticky honey on a section of tiled and wooden floor. I found that the liquid soy sauce was cleaned away in a single pass, while the thick, dried soy took two passes to remove. A third pass was needed to get the floor squeaky clean. The wasabi paste and honey both took two mopping passes to fully clean up, leaving no trace behind.
The bot washed the mop pads between each test – removing any contamination from previous cleanups. That said, the X40 Ultra is not designed to mop more than a small amount of liquid, as the pads are meant for scrubbing, not sponging.
The only issue I noticed is that the strong magnet in the mop pads (used to attach them to the vacuum) tends to pick up tiny particles of magnetic dirt. It’s normal for some dirt to be slightly magnetic (due to iron content), and this accumulates on the plastic spindle of the mop pads. The mop washing process doesn’t remove this dirt – in fact, it increases wear on the base station – and the slightly rusty residue can stain the mop pads or potentially other flooring during mopping. To avoid this, regularly wipe away any residue remaining on middle of the mop pads.

Base station performance
Dreame rates the 3.2-liter (108 oz) dust bag in the base station for up to 75 days of use – but how long it lasts for you will depend on how large or dirty your home gets. The robovac itself has a 0.3-liter (10 oz) dust bin that is emptied by the base station as needed when full, or it can be set to empty after every room.
While I was impressed with the suction on the bot itself, the base station suction is weaker than expected. I found it didn’t always manage to fully empty the bin in the robovac, leaving debris to build up if not manually cleaned. Worse, despite all its smarts, the robovac couldn’t sense when the base station had not successfully emptied its bin – or tell that it was clogged and not vacuuming effectively. That meant it would often do an entire home vacuum while clogged and not pick up anything.
Even when the base station successfully empties the robovac’s dust bin, the low suction means the debris tends to form a clog right at the mouth of the dust bag. This clog would further reduce the suction, worsening the emptying problem. I found the situation could be somewhat alleviated by setting the base station’s auto-emptying frequency to the highest setting and occasionally manually triggering an extra empty cycle. It also helped to ensure the dust bags were very carefully installed with no folds of fabric near the inlet – or to occasionally manually shift the collected debris further into the bag. Even so, I needed to change the bags well before they were full, and I found they only lasted half as long as the 75-day rating from Dreame.
This is the main reason I would find it hard to recommend the X40 Ultra for a household with pets that shed hair (like golden retrievers or huskies) or one with a lot of debris to vacuum up – as the base station suction just isn’t powerful enough to ensure problem-free operation and economical use of the dust bags.
On the plus side, the mop washing system works very well, and I only encountered one minor downside during my testing. The base station heats water and dispenses it into the washing system, then circulates it against the mop pads while the robovac spins the mop pads against plastic scrubbers to remove any contamination. The used water is then sucked out and stored in the dirty water container, and the mop pads and cleaning system are dried using hot air to avoid any odors. The washing process is a little noisy at time, like when the pumps runs, and the drying fan does make a quiet whir for a few hours.

Dreame X40 Ultra review: App control
Deep customization of scheduled cleans
Homescreen widgets and shortcuts
The app is sometimes laggy and feels unpolished
Image 1 of 2
(Image credit: Future)
Image 2 of 2
(Image credit: Future)
While the X40 Ultra can be controlled in a limited way using the buttons on top of the circular bot, the app is the best option for everyday use. It makes it easy to interact with the map of your home – created immediately after setup and updated during each clean – and allows you to customize cleaning sessions. The depth of control is noticeably better than competitors such as Ecovacs, and you can fine-tune much of the robot’s day-to-day operations, as well as check the comprehensive cleaning history.
I found the layout and navigation of the app frustrating at times. For example, many frequently used options – like adjusting scheduled cleans – are buried a few layers deep in the menu system, and such settings are locked out when the robovac is in operation.
In my three months of testing, the X40 Ultra only failed to start a scheduled clean once (with no discernible reason) and completed the next day's clean without a problem. The robovac will only connect to a 2.4GHz Wi-Fi network, and I found it sometimes had issues with a typical dual-band (2.4GHz and 5GHz) mesh network – like you’d find in our guide to the best mesh Wi-Fi systems. At one point, the X40 didn’t want to connect to my network, and a few times it reported low signal strength despite being right near the router. I found it much more stable to configure a dedicated 2.4GHz Wi-Fi SSID for the robovac to connect to.
While the Dreamehome app is less polished than expected for such a premium robovac, it’s not better or worse overall compared to the competition. Sure, brands like Ecovacs and Eufy offer apps that are nicer to use in many ways – but neither provides the same depth of control options, and they still suffer from lag and the occasional missed clean.
App score: 4 / 5
Dreame X40 Ultra review: Consumables and maintenance
The X40 Ultra comes with everything you need to get started right away, but there are only two dust bags included, along with one small refill of floor cleaning fluid. This means you need to either buy spare bags when purchasing the vacuum, or order them within a month or two. The X40 Ultra consumables (main vacuum brush, mop pads, floor cleaning solution, vacuum bags, side brush and robovac dust bin filters) are mostly only available via the Dreame website in the UK and Australia, whereas in the US they are easier to buy from Amazon than they are from Dreame.
The Dreame app keeps track of each cleaning session and provides an estimated remaining life (in hours) for the consumables and wearing parts. The estimates generally seem quite conservative, and I expect many parts – like the main brush – will last longer than rated and need less frequent changing than expected. Maintenance for the Dreame X40 Ultra is fairly simple and takes about 10 minutes a month. It’s not messy or difficult to do and mostly involves giving the robovac a check-over, dusting off the sensors, and removing any trapped hair if needed. The latter involves removing the main or side brush and simply sliding the wrapped hair off – and I didn’t have to cut any free during my testing.

Extrapolating my three months of testing to a full year, and using the remaining life estimates in the Dreame app, the X40 Ultra consumables include 10 to 12 dust bags, one filter, one side brush, a container of floor cleaner, one set of replacement mop pads, and one replacement TriCut brush – adding up to around $200 / £163 / AU$500. For a larger home, this cost could easily double or triple. Notably, in Australia (where the X40 Ultra was tested for this review), the TriCut brush is 170% more expensive compared to the US and UK – so using the normal brush saves AU$150 a year.
While using the official Dreame accessories is recommended, there are third-party consumables available from online retailers like eBay and Amazon. The best are nearly indistinguishable from the official Dreame parts, while the worst are of very poor quality and won’t work correctly. Until Dreame offers affordable bulk packs of dust bags, it’s hard to pass on third-party alternatives – provided you can find good-quality ones.
Consumables and maintenance score: 3.5 / 5
Should I Buy the Dreame X40 Ultra?
Buy it if…
You want a premium robovac with the latest features There are very few competitors that can come close to matching the extensive functionality offered by the X40 Ultra.
You need excellent obstacle avoidance The X40 Ultra is very skilled at avoiding anything that might cause it to get stuck, as well as cleaning around obstacles or even accidents from your pets.
You have deep pile carpets The X40 Ultra’s party trick is being able to leave the mop pads at the base station, allowing it to vacuum through the plushest of carpets with zero chance of dampness or cross contamination.
Don’t buy it if…
You have pets that shed more than average The robovac itself is great at picking up fur and other debris, but the base station auto-empty system lacks suction and the bag needs to be changed before it’s full to avoid clogging.
You only have carpet The X40 Ultra does a fantastic job of mopping and keeping its mop pads clean, but if you don’t have much in the way of hard floors, you’ll save a lot of cash opting for a cheaper vacuum-only robovac.
You want a cheaper option The X40 Ultra is great, but it’s also one of the most expensive robovacs available. For those on a budget, there are plenty of other great options at more affordable prices.

How I tested the Dreame X40 Ultra
I used the X40 Ultra as my main vacuum cleaner for three months
My testing space included hard floors and carpet
I performed specific grain-size and wet-spill tests
I used the Dreame X40 Ultra daily for three months in a home with a dog and two adults. I tested the X40 Ultra on polished wooden floors, tiles, carpet, and medium-pile rugs. The weather during the test period included both wet and dry conditions. I started with an initial deep clean, followed by ongoing daily vacuuming, with mopping once or twice a week – plus extra spot cleans as needed. I tested both the automatic CleanGenius mode and customized cleans using schedules and shortcuts.
I documented cleaning performance over the testing period and conducted a range of specific tests with different debris sizes to further gauge vacuuming ability. I also tested dry and wet spills to evaluate the mopping prowess. Additionally, I strategically placed debris – including fur, leaves, and hair – in problem areas such as corners to assess the robovac’s effectiveness in daily use.
During my testing period, I changed the base station vacuum bag three times, manually cleaned the mop cleaning system in the base station, and performed the full range of maintenance checks.
Narwal Freo Z Ultra Robot Vacuum and Mop two-minute review
Launched to great acclaim at Europe’s biggest tech show, IFA (where it snagged two awards), the Narwal Freo Z Ultra is a successor to the brand's Freo X Ultra. Significant upgrades include dual RGB cameras, LiDAR navigation, and an increase in suction power from 8,200 to 12,000Pa. In layman’s terms, it’s better at obstacle avoidance and adaptive cleaning, plus it sucks up more dirt!
In my tests, I found the Z Ultra excelled at both mopping and vacuuming on hard floors (of which I have many) but it was less cool on carpet. To be fair, I’ve tested some of the very best robot vacuums and am yet to find one that can handle dusty carpets as well as the best manual vacuums for carpet, which always have more power and better filters.
I loved all the smart automation, which meant I didn’t have to zone off carpets to stop them getting soggy or worry about what power level or speed to set. As a germophobe I also really appreciated how hygienic this robot is; cleaning and drying itself after every session.
Its mapping powers were also great, but I would have liked a quick option for spot cleans. Many robots allow you to mark a zone on the map where there’s a spill and send the robot straight there to clean. The only way I could work out to do this was in video mode, where you can manually navigate the vacuum. The issue here was the video was glitchy about connecting and often flatly refused – not ideal if you have spilt something that could stain and needs speedy attention.
I also had a few bin-related issues, and mopping was deadly s-l-o-w, but absolutely worth the wait. Ideal for large homes with mostly hard surfaces, the Narwal Freo Z Ultra suits tech-savvy homeowners who appreciate an integrated app and can get their head around fine-tuning settings. Technophobes and the impatient (and anyone on a budget) might prefer to steer clear.
Read on for my full Narwal Freo Z Ultra Robot Vacuum and Mop review.
Narwal Freo Z Ultra review: price & availability
List price: $1499.99 / AU$2,499
Launch date: October 2024
Availability: US / AU
The Narwal Freo Z Ultra launched in October 2024 and at time of writing is available to buy in the US and Australia, with a list price of $1,499.99 or AU$2,499. That places it firmly in the premium price bracket. There’s no getting away from it, the Narwal Freo Z Ultra is a pricey robot vacuum sitting at the very top of the market in both Australia and North America. You can save a few dollars by waiting for seasonal sales (the Black Friday deals often include some big robovac price-drops).
There are two accessories pack options. Option 1 will set you back an extra $259.99, and costs of a whole raft of brushes, detergents, dust bags and mop pads. Option 2 gets you a few of the most-used accessories, for $100. You can also add a one-year extended warranty plan for $79. Buying the accessories individually will soon add up – a replacement detergent is $29.99 – so it’s worth doing the math before you decide which option to start with.
While the Narwal Freo Z Ultra is an investment appliance, it will save you a LOT of time and it’s by far the best mopping robot I’ve tested. I wouldn’t buy it purely for vacuuming, but as a combo, it might be worth the spends.

Narwal Freo Z Ultra Robot Vacuum and Mop review: design
Stylish robot with mopping and vacuuming skills
Large mop heads and spinning brushes for getting close to edges
Decent capacity water reservoirs
Arriving in a huge box, I needed an extra pair of hands to unload the Z Ultra and was grateful for the hand grips in the base station when positioning the heavy unit next to a power point. It comes with a simple instruction card for first-time setup, as well as a more comprehensive user manual. I used the former to install the side brushes, insert the detergent and add clean water. My daughter got a lot of satisfaction from removing a gazillion instructional stickers from both the base station and vacuum unit.

The design of the Freo Z Ultra, and base station, is very stylish indeed, which is just as well given that it’s hard to hide! Choose from Galaxy White or Space Gray. All the edges are softly curved and, with its two camera ‘eyes’ in the front, has the cute vibes of Pixar’s Wall-E, which is exactly how I like my robot vacuums. The various lids and covers pop off without breaking any fingernails, and everything is easy to access.

Underneath, this robot has two large microfibre style mops that Velcro on, as well as two rotating side brushes that are a good length for getting into corners. The main roller brush has a rubber flipper part as well as brushes to suit both hard floors and carpets, plus its anti-hair tangle design does actually work. As I have two daughters and two spaniels who seem to molt year-round, I was delighted to swerve the odious task of cutting swathes of hair from around a roller. (Effective anti-hair wrap brushrolls are a key feature amongst the best robot vacuums for pet hair.)
One unusual feature I’ve not seen anywhere else is a fluffy baseboard duster that attaches with Velcro on one side and is designed to gather dust from the tops of your skirting boards as it goes along the edges of the room

The Narwal Freo Z Ultra’s base station has two large containers for clean and dirty water. These are are easy to lift in and out, but you'll want to make sure the dirty water reservoir’s lid is properly clipped on, or you may have to clean up a mini flood.
The dirty water bin is very satisfying to empty! (Image credit: Future/Linda Clayton)
There’s also a dust collection bag and compartment into which to slot the bottle of floor cleaning solution that’s supplied. The bot does work without the detergent module in place, which is handy given they cost nearly $30 a pop. There’s a cool little window strip in the base that shows the water being ionized. It’s not clear why the water needs to be ionized but if you like watching bubbling water, take a peek.

Narwal Freo Z Ultra Robot Vacuum and Mop review: performance
Amazing at obstacle avoiding and navigation
Great at mopping, poor on carpet
Self-cleaning is great, but self-emptying hit and miss
The first job any robot vacuum has to complete is a map of the house, which this little beauty did in 17 minutes – impressive given we have quite a few little rooms, and many obstacles. (Here's more on how to prepare your house for a robot vacuum, if you're unsure.)
The mapping was precise and accurate. I liked how the map shows where the rugs and carpets are; often you have to add your own, which requires some guesswork on precise positioning. I’ll discuss the App in more depth later, but it was easy to name each room and set up no-go zones and divide rooms. Another bonus of the Freo Z Ultra is the ability to choose from a wide menu that covers mop, vacuum, mop & vacuum, and mop then vacuum. Some models I’ve tested don’t allow you to just mop.
The robovac didn't get quite as close to the edges of rooms as I'd like (Image credit: Future/Linda Clayton)
Once I’d got to grip with the controls, I loaded up the water tank and tasked the Freo Z Ultra to vacuum and mop my entire ground floor, which is mostly engineered wood, with some terracotta, porcelain, luxury vinyl and of course rugs and carpet. Pretty diverse then.
While it was possible to set my own cleaning parameters, the Freo Z Ultra has an AI mode that uses various sensors and cameras to automatically adapt to different floor types and dirt levels. This takes the brainwork out of setting up and ended up being my go-to mode throughout my three-week trial period.
The first thing I noticed was how good the Freo Z Ultra was at obstacle avoidance – no banging into furniture or corners and no dragging cables or dog toys around the floor with it. (TechRadar's article on how robot vacuums navigate walks through the typical approaches brands use.) I never once got a message to say the roller brush was stuck, which is the usual warning that a robot has eaten something it shouldn’t! It was also excellent at powering over thresholds and the annoying chair legs I have that robot vacuums usually get grounded on, and spin like mad until sending a stuck error message.
(Image credit: Future/Linda Clayton)
The second thing I noticed was how it doesn’t get terribly close to the edges in mopping mode. When vacuuming, I could see the little spidery side brushes pulling dog hair and dander in from the edge but in mop mode there was a clear inch or more of bone-dry flooring around the perimeter of the room and any floor-level furniture like our kitchen units and sideboard.
And on the subject of edges, I’m sorry but the little fluffy baseboard duster on the side of the robot is only going to work if you have super low baseboards. Like many heritage properties, the baseboards in our Victorian home are quite high so it doesn’t reach the tops, aka the only bits that need dusting.
The mop edging wasn't brilliant, especially alongside the kitchen kickboards. (Image credit: Future/Linda Clayton)
The Freo Z Ultra doesn’t carry any water onboard, which is unusual. Instead, it loads its mops up with warm, soapy water at the base station before heading out to clean. I was concerned this would result in dry patches of flooring, but the dampness levels were perfect – not too wet (important on real timber flooring), nor too dry.
The only downside is it has to make repeat returns to load up with more water, which can elongate the cleaning time, especially in rooms that are furthest from the base. For example, it took 1hr 19mins to mop our utility and hallway, which is an area of just 40 sq m. To vacuum and mop the whole ground floor, 68.3sq m, the Freo Z Ultra took a tedious 2h 41mins. Imagine how long it would take if I asked it to vacuum and then mop, rather than do it consecutively. I didn’t want to find out! I’ve never tested a robot that spends longer than two hours on the job.
When the robot returns to base after mopping and vacuuming, it automatically empties the bin and cleans its mop heads and then dries them. The latter takes a couple of hours but it’s incredibly quiet, so you won’t notice it. I did have to set the bin emptying to every run on the app, otherwise it clogged up and couldn’t self-empty itself. Hardly surprising given how microscopic the onboard bin is. Even then, there were a few times the bin just wasn’t self-emptying, even though it said it was, which was frustrating.
(Image credit: Future/Linda Clayton)
There are a handful of extra features – perhaps the most interesting one being that in Video mode you can see through your robot’s 'eyes' and remote control it around your home. That means you can use it as a security bot, or to check up on pets and send it off to specific locations. This mode isn't authorized by default, you'll need to manually switch it on if you want to use it.
Cleaning tests
When it came to running our standard vacuuming tests – one using a fine mix of biscuit and flour, and another using oats to represent larger particles – the results were a mixed bag. The Freo Z Ultra did well on the hard floors, eventually anyway. It took at least three passes and full power mode to get everything up.
I used multiple ‘no-go’ zones on the map to create my 1m x 1m test area, but the robot still seemed to spend far longer cleaning around the area I had made my test spills than it did actually dealing with the mess. This led me to seriously question Narwal’s claims that it homes in on and targets dirt using its beady little cameras and sensors.

With oats on carpet, the results were middling. The robot pushed things around a fair bit and it took three runs before they were gone. The dog may have helped!

On carpet, the fine mix removal was very disappointing. I gave up after three attempts and got my cordless vacuum out. Although this isn't great news, I'd argue that it's not often you'll experience this level of concentrated 'dust' and I was always happy with its carpet cleaning results in general.

Next, I tried out the mop function by 'spilling' first Ribena juice and then ketchup, which I left to dry, on the porcelain tiles in our cloakroom (I didn’t want to risk stains on our timber floors). These results were much better, although the dried-on ketchup required two passes to complete the job. According to Narwal, this impressive mopping is achieved via dual rotating mop heads that press down with 1.2kg of force and spin at 180 RPM. Other robot mops I’ve used either just drag a static mop pad along, or have a vibrating mop, this spinning tech is the closest I’ve come to mimicking real mop work. And the results show it.
Apparently, this robot also analyses the waste water to decide if another cleaning run is required but I had to make that decision myself with the ketchup; the Freo Z Ultra thought it was done after one attempt.
To check navigational skills, our final test involves placing a sock (in a similar shade to the flooring) a shoe and a charger cable on the floor. The Freo Z Ultra absolutely nailed this test, not touching any of the objects but getting close enough to clean sufficiently around them.
All these common objects were successfully swerved. (Image credit: Future/Linda Clayton)
The Freo Z Ultra takes around 2.5 hours to charge, which is a bit speedier than normal, and has a run time of just over 2 hours 15mins (in vacuum and mop mode), which is about the standard for a high-end robot. It automatically returns to the base to charge if it runs low on juice during a cleaning cycle, which is also the norm. If I was asking it to do the whole house, it never managed on a single charge but I usually tackle the dirtiest rooms (kitchen and hallway) more frequently and that was easily done without the need to stop to recharge.
Noise-wise, I am quite noise intolerant and as I work from home, I don’t like having noisy robots rattling around the house while I am trying to focus. Happily, I found the Freo Z Ultra one of the quietest robots I’ve tested, especially in mopping mode, with my decibel meter App recording between 60-70dB max. This is way below the noise levels you would get from a regular vacuum, but if they still bother you, just schedule the robot to work while you’re out of the house.
Maintenance
I found the Freo Z Ultra easy to clean and maintain, the internal bin pops out for emptying, if it hasn’t emptied automatically into the base station, and the mop heads are automatically washed with hot water and dried after every use. This is important to prevent bacteria breeding in the mop heads and before being dragged all over your home. All this self-cleaning did mean it rattled through the clean water in the tank and I had to refill it before most cleaning runs, but that’s a small price to pay I’d argue.
Like all robot vacuums, it’s important to keep the sensors and charging contacts clean, which is an easy wipe-over task. The roller brush didn’t clog in the three-week test period, but if they had, they do clip out very easily. I also didn’t fill the dust bag in the base station but it just clips out and pops straight in the bin when full.
Narwal recommends cleaning the filter once a week, which involves clipping it out from under the top cover on the robot and tapping out the dust – simple. It should be replaced every three-six months.

Narwal Freo Z Ultra Robot Vacuum and Mop review: app
Very easy to work out without assistance
Lots of options to customize cleaning (or not)
Mildly glitchy connection
The Narwal Freo Z Ultra app is user-friendly and intuitive (I never needed to use the Help Center), making it easy to create custom cleaning schedules, adjust settings, and monitor cleaning progress in Real Life. Make sure you connect using a 2.5GHz wi-fi link, not 5GHz.
If you love an easy life (as I do), you can clean in Freo Mind mode, which leaves all the decisions about power levels, patterns and passes to the robot. If you’re a control freak, each cleaning program comes with various adjustment options, such as mopping humidity, coverage precision, detergent use etc.
You can choose which rooms to clean, but I also liked that I could set the cleaning sequence for a full home clean. For example, I set it to start in the kitchen, then hallway, then dining room (where my desk is), so that it gets those rooms I spend most time in done first (while I’m taking the kids to school). You can also split rooms, merge rooms and add no-go zones.
The app also provides cleaning history and notifications to ensure you stay informed of cleaning progress. I did experience quite a lot of delays between opening the app and the robot syncing, but we’re only talking seconds. And it often annoyed me that there was no Spot Clean option but that may well come with a software upgrade.
App score: 4 out of 5
Should you buy the Narwal Freo Z Ultra Robot Vacuum and Mop?
Buy it if…
You’ve got lots of hard floors
You’ll probably need to give carpets a thorough clean with a more powerful vacuum once a week or so, but you can save your mop for emergency spills – this robot has got regular mopping covered.
You want to spy on your pets
In Video mode you can see through your robot’s 'eyes' and remote control it around your home to hunt out and check up on pets while you're out.
You’ve got a messy home
While it’s always worth picking up stray toys and shoes etc. before your robot cleans, sometimes you just don’t have time. Luckily this robot has amazing obstacle avoidance – I never had issues with it its roller brush getting blocked by shoelaces or charging cables.
Don't buy it if…
You’re on a water meter
Okay, so it’s not so thirsty your water bill will rocket but you will need to refill the large water tank (and empty the dirty one) a lot, depending on area. For me, it was every full ground floor clean. You can adjust the reduce water use in the app, but I didn’t find the results as good.
You’re impatient
Frequent returns to base to wash the mopheads and replenish with clean water takes its toll on timescales. This was by far the slowest robot I’ve tested. I tended to set it going when I knew I’d be out of the house for a couple of hours.
You’ve got loads of carpet and rugs
This is robot is too expensive to not take full advantage of the mop mode, and there are more powerful suckers out there for a lot less if you have mostly carpet.
How I tested the Narwal Freo Z Ultra Robot Vacuum and Mop
I tested the Narwal Freo Z Ultra Robot Vacuum and Mop for three weeks on the ground floor of my four-bed historic home. With the exception of thick-pile carpet, we have all manner of flooring types from porcelain and terracotta tiles to vinyl and engineered oak. I ran the robot in various rooms, in every cleaning mode, every day and tried cleaning in both automatic smart mode and fully customized. I also set schedules and conducted controlled tests where I had the robot vacuum flour, crushed biscuits and oats from hard floors and rugs, as well as mop wet and dried on spills from the porcelain tiled floor.
The fourth-generation Nest Learning Thermostat blends a terrific redesign with the smart features that we've all come to expect from the company's devices. Google arguably set the bar very high back in 2011, with a control set that mirrored an iPod, and the ability to learn your cooling or heating schedule from the get-go.
Between the facelift that makes it look more like a piece of art on your wall and the 'AI' power infused into its already well-regarded learning features, the fourth-generation Learning Thermostat is a pretty easy recommendation for most folks. Even when accounting for the price increase of up to $280, the fourth-generation model is more than a bit smarter, and now includes a temperature sensor in the box as well.
I especially liked the smaller changes, including the ability to accept or decline suggested temperature changes to my schedule, but besides the design, the best functionality change is the adjustable and more helpful display. Displaying the active temperature and visual for the weather from afar, and showing highs and lows as I get close, the FarSight feature means the new Nest Learning Thermostat is useful even when I'm not using it to adjust temperatures.
Setup within the Google Home app was easy for me, but my colleagues weren't as lucky, and most of the experience with the app is pretty basic. It might be intentional, but something a bit more full-featured would have been nice. Even so, adding Matter will make the folks waiting to use a Nest natively in the Apple Home app pretty darn happy. Myself included.
As a whole, the fourth-generation Nest Learning Thermostat evolves into the modern age of the smart home in a successful fashion, which I think will make folks upgrading from a previous model quite happy (even though it's not plug-and-play). People new to Nest will find it to be feature-filled. That makes the decision of only releasing the fourth generation in the United States and Canada a bit more baffling.
Nest Learning Thermostat 4th Gen: price and availability
The Nest Learning Thermostat Fourth-Generation is available in the United States and Canada. You get your pick of Polished Gold, Polished Silver, or Polished Obsidian for $279.99 in the United States, or $379.99 in Canada. A temperature sensor is included in the box, but you can buy a single additional unit for $29.99 or a three-pack for $99.99.
As of now, there is no timeframe for when the fourth generation might launch outside the United States or Canada.

The new Nest Learning Thermostat looks stunning.
It was a simple install, though it's not plug-and-play if you're upgrading from an existing Nest.
The larger, upgraded display steals the show and navigation is still impressively simple.
While the fourth generation model still inherently operates like the original Nest Learning Thermostat that dropped way back in 2011, it’s by far the biggest redesign the device has ever received. When mounted on the wall, it looks more like a piece of art hanging than a thermostat – especially in the ‘Polished Gold’ that I’ve been testing, which gives major rosy vibes when the light hits it right.
It’s the best-looking smart thermostat around, neither screaming 'technology' nor resembling a classic plastic thermostat. It’s sort of a cross between the two, with a design that allows the true smarts of the Nest Thermostat to shine through. More on that later.
Rather than a small, thick circular thermostat that gets placed on a bracket and then a mounting plate if you so desire, the Nest Thermostat fourth-generation has a slightly larger footprint on the wall itself. That’s not a bad thing, because this circular piece is attached via the bracket to your wall, acting as the stand for the thermostat's slim and elegant main hull.
It’s kind of like a supersize Google Pixel Watch 3, with the 3.9-inch circular, almost bezel-free dome giving the impression that it’s floating. You’ll turn this whole piece to the right or left to raise or lower the temperature. Google’s design team is still adamantly against touchscreens here, so you’ll click and turn it to complete most other tasks too (including some parts of the setup process), but you'll mainly use it to adjust heating and cooling modes.
The installation was really a breeze; in my apartment in New Jersey, where I’ve been testing the fourth-generation Nest Thermostat for several months, it took me no more than about 15 to 20 minutes to install. I wasn’t upgrading from a previous Nest, but considering the plate here is a different size, you will need to swap those out if you are. That's kind of a bummer, as it’s not a super simple swap for the faithful already invested in the ecosystem.
(Image credit: Future/Jacob Krol)
Still, Google provides mostly everything in the box, including the main bracket and a helpful wiring guide. Essentially, you’ll install the main steel bracket and use the included screws to get that on the wall. Then you have the thermostat base, which you’ll guide the wires through. You also get the mounting plate, which I opted to use, but that's optional.
The idea is that if you're currently using the Nest app, it will push you to use the Google Home app instead, and if you’re new, you’ll need to start with Google Home. Even if you bought the Nest Learning Thermostat for its Matter capability so you can use it with Apple's Home app (which does work eventually), you need to start with Google Home. Luckily, the team brought the easy installation help to the Google app, which will perform some checks, including a test of heating and cooling modes.
Once it's set up in Google Home, you get to take advantage of the major benefit of the Nest Learning Thermostat, and that’s the Matter support. Oddly enough, there is no Thread connectivity here, which is a strange omission. If you select your Nest Learning Thermostat within the Google Home app and then navigate to Settings > Device information > Linked Matter apps & services, it will generate a code that you can scan or send to Apple’s Home app, for example. You can also select and review the Matter code on the Nest Learning Thermostat itself.
You’ll need to set it up with a Google account in the Google Home app first, but the nice thing about a Nest thermostat is that the app eventually fades away, and you can focus on controlling it from the device itself or let the smart scheduling take the wheel.
As far as the classic mechanic, it’s smooth as ever with just the right amount of resistance to maneuvering the dial I’ve had more than a few friends ask me what it is when spotting it on the wall in the front of my apartment – it’s simply an eye-catcher.
The 3.9-inch LCD screen almost appears like it’s hidden behind the finish – a cool effect – and the content can change based on where you are. For example, if it doesn’t detect you directly nearby, it will use larger graphics that can be seen from a distance. If you approach, the Soli sensor – read as radar – will detect you and adjust the content as you get nearer. It’s dubbed the ‘Farsight’ display, and you can adjust it to show high and low temperatures, air quality, and even weather. You’ll set these from the device itself, but the weather animations are really neat.
It’s also a point of difference with competing thermostats like those from Ecobee, which tosses a speaker and a microphone into select models. I think the Nest Thermostat packs features that make more sense. Seeing the weather quickly as you’re heading out the door or picking what coat to wear is neat.
The display feels inherently meshed with this new look – it won’t steer away the folks who have loved Nest from the beginning, and it really looks dynamite. There also isn’t a better control system than just turning to the left or right and pushing in. Apple had it first with the iPod, but considering multitouch, I think it’s the gold standard for thermostat control.
Design Score: 4.5/5
Nest Learning Thermostat 4th Gen: Performance
(Image credit: Future/Jacob Krol)
The Google Home app is pretty basic, and it has some connectivity issues.
Yes, the Nest finally works with Apple Home.
The AI-infused learning features impress and make cooling or heating a home easier.
I’ve been testing the Nest Thermostat Fourth-Generation for several months, which means I’ve used it for a few seasons, including summer, fall, and winter. That’s pretty important to see how the smart scheduling reasoning and, ultimately, the functionality of the Nest handle the swap from cooling to heating.
Much like any other gadget released in 2024, Google has tossed in some AI capabilities, mainly affecting how the Nest Thermostat adjusts the temperature. This makes the previous learning aspects of Nest – arguably, the main appeal – a bit smarter and quicker once you get in a rhythm, but also more actionable. For instance, with the new Smart Schedule feature, you can accept or decline the adjustments it suggests, whether that’s a degree or cooler at night or warmer in the morning.
Further, as it begins to notice the change from cooling or heating, it takes a few days to stop suggestions and focus on learning before updating and delivering a custom schedule that you can manage if you like.
These minute changes that the Nest Thermostat suggests could lower your energy bill (aka the cost of cooling or heating your home), but you may not see those impacts immediately. What you might be able to do here in the United States is to see if your utility provider offers any rebate for the cost, as the latest Nest isn’t the cheapest.
Beyond learning from your habits and adjustments – on the thermostat, via the app, or through a smart assistant – it will consider conditions around your home. For example, if it’s a warmer day in the winter, it might lower your heating temperature to save on energy and factor in that your home might stay warmer for longer on its own. It's the same thing for a cooler summer day, and it works quite well. Similarly, if your forecast predicts a frigid temperature turn, it might turn the heating on earlier to ensure you’re still at a comfortable temperature in your home.
(Image credit: Future/Jacob Krol)
As with previous Nest thermostats, you can expect all of these to get better as you spend more time with the unit, and that’s exactly what I’ve found. I wouldn’t go into it expecting it to master your desired temperatures after just a few days, but you need to spend a week or two with it to see meaningful suggestions.
The thermostat also comes with a pebble-shaped sensor, which helps measure the temperature more accurately inside your home. The idea is to place this somewhere in your house away from the Nest Thermostat, which contains its own sensor, so it can get a proper read of the temperature and ensure the desired conditions are found throughout.
Including this in the box is pretty nice, and helps to make up for the price increase to $280. Unfortunately, although the Nest Thermostat works with Matter and therefore Apple Home the sensor doesn’t seem to move over. There were also several occasions when adjusting the temperature in the Apple Home app didn't work properly the first time, especially shortly after I first installed the unit. Thankfully that's now become far less frequent, and I’ve successfully controlled it from a range of Apple devices and through Siri. You can also integrate it through automation within Apple Home; the same goes for Google Home’s automation.
As far as the Google Home app goes, it’s pretty basic for controlling the Nest Learning Thermostat, but that might be intentional as the real appeal is these AI-infused learning features, which ultimately still impress. The fourth-generation Nest Thermostat shows an evolution in terms of features and revolution with design, but it’s still a compelling experience that lets you spend less time fiddling with a thermostat.
Performance Score: 4/5

This may seem a little steep for a small light-up lamp but, if like me, you’re a fan of anything bright and colorful, appreciate extensive customization options, and enjoy the convenience of a smart lamp, then it’s definitely worth the cost.
When it’s off, the design of the Govee Table Lamp 2 looks pretty nice. It’s got a modern aesthetic, with silver-colored accents and a pearly finish on the circular control panel. The lamp's outer doesn’t have the cheap, unattractive finish that many lower-cost RGB lamps do; in fact, it looks like it could be made of glass, and the ridged titanium-colored inner makes for a nice feature.

The only slight negative I found was that the outer surface proved to be a bit of a dust and fiber magnet. I noticed a subtle texture on the side of the cylindrical lamp and realized that fibers had accumulated after only a few hours of use. This isn’t hugely noticeable, though, and our reviews office sees a lot of cardboard boxes and products daily, so the dust levels are certainly higher than average.
The controls on the device include power and two brightness adjustment buttons on the top panel, as well as color and scene cycling buttons that can be customized within the Govee Home app, meaning I was able to assign eight different colors/lighting effects to each button respectively.

Naturally, the design really came to life when the Govee Table Lamp 2 was on, and the effects were as beautiful as anything from the best smart lights. There’s a huge array of fantastic effects on offer via the Govee Home app, including several preset color collections, an RGB color wheel, plus another sectioned color wheel to choose colors. The latter had different emotions assigned to different color areas; choices included jolly, surprised, concerned, disappointed, and aggravated. I’m not sure I associate purple with “horrify” myself, but the assigned emotions amused me, anyway. There were over 60 scene presets to choose from, with collections of lighting effects arranged under themed tabs such as natural, festival, and sleeping, and I had great fun investigating them all.
(Image credit: Future)
My personal favorite scenes were some of the most colorful (naturally): Rainbow produced a beautiful gradient of pastel colors that slowly swirl about the outside of the lamp, and Fish Tank showed colorful shapes swirling around the center of the lamp. A great additional feature with some of these presets is that I could alter the speed, so I could set them to be as calm or as energetic as I fancied. On the few occasions I didn’t want colorful lighting effects, say when I wanted a warm light to read with, or to brighten the immediate area up, this lamp had me covered with a temperature range of 2700 – 6500K.
As if the huge array of scene and color presets weren’t enough, the AI feature was fantastic. It was like an easy-to-use online chat format, and I could ask it to create a scene via text or voice command, or take or attach a photo. I decided to take a photo of a stack of boxes in the office, and the AI bot recommended a “vibrant, dynamic lighting effect that dances and shimmers, mirroring the colorful packaging”. I accepted the recommendation, and the resulting light effect was a gorgeous pale lavender and pastel orange gradient that slowly waved from the bottom in an upwards diagonal direction – I was then able to save it to my DIY library.

The Govee Home app was delightfully easy to navigate and provides a great user experience. The different light features are laid out simply under labeled icons, and I really appreciated that the app allowed me to adjust the layout to suit my needs, allowing me to sort, hide, and show the quick access and modes right where I needed them.
Wonderfully bright and colorful even in a well-lit office, the Govee Table Lamp 2 was even more so in darker environments. Even on the bright white setting in darkness the light is diffused enough not to be harsh on the eyes, and the warmer lights targeted toward reading and night-time were soft and comforting.
One thing I noticed is that the Table Lamp 2 became warm after a little while, but not to a concerning extent. As I tested it in the winter, it actually proved to be a positive, as it was nice to feel a slight warmth when using the touch controls.
(Image credit: Future)
After an enjoyable period of testing and other than it collecting a little dust, there was nothing I didn’t like about the Govee Table Lamp 2. When unlit, it was unobtrusive and attractive, as much as one of these lamps can be. And when switched on it provided beautifully eye-catching and colorful light displays with what felt like endless scenes, combinations, and customizations.
As a lover of anything colorful with plenty of options to mix things up, I’m a huge fan of this smart little lamp, so if this is something you’re in the market for, you won’t feel let down by the Govee Table Lamp 2.
Govee Table Lamp 2 review: Price and specs
Should you buy the Govee Table Lamp 2?
Buy it if...
You want a light with lots of options and customization This table lamp certainly isn't lacking when it comes to preset scenes and options to make your own. From personalized color collections to speed and brightness levels, the intuitive Govee app makes it light work to create the effects you want.
You want to go hands-free The fantastic app isn't the only smart feature here as you can easily connect the Govee Table Lamp 2 to smart home tech like Alexa or Google Assistant, plus it has Matter connectivity too.
Don't buy it if...
You want a lamp that's super bright as well as smart It's perfectly bright enough for reading or when working close to the lamp. However, as one would expect from a lamp of this size, it isn't going to illuminate a room.
You want something cheap and cheerful While this lamp certainly gives some bang for your buck, it is on the pricey side. There are plenty of cheaper alternatives floating about – just be mindful that the build quality may be lacking, and you might be hard-pressed to find anything with such a satisfying array of features.
Govee Table Lamp 2 review: Also consider
Philips Hue Twilight If you've got (a lot) more to spend, and you're a die-hard Philips smart home tech fan, then this purpose-built wake-up light could be the one for you. It features two light sources, one at the rear of the lamp that scatters color up the wall, and one inside the lampshade. It features an attractive, modern design, and two buttons for automation and light control, but you'll need a Hue Bridge to make the most of all the features.

How I tested the Govee Table Lamp 2
I thoroughly enjoyed using the Govee Table Lamp 2 for one week
I tested the different features and customizable settings
I observed the brightness and visibility of the scenes in light and dark environments
I used the Govee Table Lamp 2 as a calming and mood-lifting addition to my desk setup in the TechRadar reviews office for one week. I evaluated the usability and performance of the Govee companion app and went down the rabbit hole playing with all the different settings.
I enjoyed exploring the various presets within the app. I also made some of my own color sequences, and used the AI scene creator from photos and prompts.
I assessed the different light modes in brighter and darker conditions to see how visible they were in daylight and bright office lights, and to see just how vibrant the colors were in the dark.
Although sporting a lower-profile design than some rivals, the Roborock Qrevo Slim is otherwise a full-size robotic vacuum and mop that is powerful, intelligent and packed with features. The redesigned LiDAR system means it can slide more easily under low furniture, getting to floorspace that other robots can't, without any noticeable compromise in navigation performance.
The well-appointed Roborock app serves up no fewer than five suction levels, plus configurability for the cleaning route and mopping performance. It also smartly raises its dual spinning mops when carpet is detected, and features a spinning side brush that pivots outwards to reach into the corners of every room.
With up to 11,000Pa of suction power, the Qrevo Slim is more powerful than many rivals, including the pricier Eufy Omni S1 Pro, and you can even view a live stream from the front-facing camera in the Roborock app, turning the vacuum cleaner into a pet monitor.
The Slim does not feature the bouncy 'AdaptiLift Chassis' found on the Roborock Qrevo Curv, which launched alongside the Slim in September 2024. However, perhaps thanks to the improved navigation system, the Slim robot itself still tackles thick rugs and raised door thresholds with a confidence missing from most rivals. It's also worth noting that despite the low profile, this is still a relatively large robot, with an equally large docking station, so it's best-suited to medium and larger homes. That's the short version; read on for my full Roborock Qrevo Slim review.

Roborock Qrevo Slim review: price & availability
List price: $1,399
Launched: September 2024
Availability: US
The Qrevo Slim launched in September 2024 and sits in the premium price bracket. It comes with a list price of $1,399, but you might be able to avoid paying that – I've spotted it discounted to around $999. At time of writing (because this market moves fast!) it sits at the top of Roborock's Qrevo range at, which itself occupies the middle tier of the company's robotic vacuum offering.
Below it you'll find the budget Q Series, and above you'll find the flagship S Series family, where prices start just below the Qrevo Slim (you'll pay $1,300 for the S7 Max Ultra), and extend all the way up to the range-topping, $1,800 S8 MaxV Ultra.
A four-figure vacuum may sound expensive, but that $1,300 buys you a lot of smart technology, and in this case your money goes into an interpretation of LiDAR known as 'StarSight', which is unique among robot vacuums, and is responsible for the Qrevo Slim's reduced height. You also get very high suction power – and in fact, at 11,000Pa, the Slim is more powerful than even Roborock's flagship S Series, which peaks at 10,000Pa. For comparison with other brands, the equally expensive Eufy Omni S1 Pro is rated at just 8,000Pa.
There is no ongoing subscription cost for the Qrevo Slim, although you'll need to purchase replacement dust bags every couple of months (Roborock says they get full in about seven weeks), and the side brush and mopping pads will eventually need replacing too.

Roborock Qrevo Slim review: design
Low-profile design fits under furniture
Self-cleaning and emptying charge dock
Dual rotating mop pads
The ‘slim' part of this robot's name refers to how it doesn't have a spinning LiDAR sensor on top. This makes it shorter than most rivals, and at 8.2 cm tall it can drive places other robotic vacuums cannot. Roborock has replaced the conventional LiDAR sensor with a system it calls StarSight. This includes a dual-light, solid-state LiDAR system, plus a 3D time-of-flight sensor, a camera and infrared sensors. (Head to TechRadar's article on how robot vacuums navigatefor a deep-dive into this area.)
(Image credit: Future)
The rest of the Qrevo Slim's design is similar to other self-cleaning robovacs in the Roborock range. The robot is circular, with dual spinning mops at the rear (this style of mop is typically better at scrubbing than the fixed, D-Shaped pad style), a rotating brush at the side that cleverly extends to reach into corners, and a pair of rotating rubber brushes underneath. The charge dock has a dust bin and a pair of water tanks – one clean and one dirty – to work with the robot's mopping function.
(Image credit: Future)
The robot itself measures 350mm (13.8in) wide, 353mm (13.9in) deep and 82mm (3.23in) tall, while the dock is 340mm (13.4in) wide, 487mm (19.2in) deep (including a ramp the robot parks on) and 521mm (20.5in) tall, although you'll need to leave space for the water tanks, which are removed by lifting them upwards from the dock.
Roborock also sells the Qrevo Slim with a refill-and-drainage system. This works in the same way, but plumbs into your home's water supply, so can refill and drain the mopping water tanks automatically. This dock is the same width and depth, but is shorter, at 405 mm (15.9in). For this review we're looking at the regular model with the larger, manually-refilled and emptied water tanks.
(Image credit: Future)
As with other such robots, the Qrevo Slim dock charges the robot's battery and empties its dust bin into a larger bag that Roborock says only needs changing every seven weeks, although that will vary depending on what you're asking it to pick up. The robot also has its mopping pads cleaned with warm water and dried during charging, while the onboard water tank is emptied into the dock.
Back to the robot itself, and the Qrevo Slim can automatically lift and lower its mops, depending on the floor surface and what cleaning task is required. The side brush and one of the spinning mops can also move outwards, touching the walls and skirting boards for a complete clean.
There are three buttons on the top of the robot for quick access to key functions, like powering up, pausing and sending it back to its dock. Removing the magnetic cover gives access to the dust bin and filter, which can then be removed and cleaned or replaced.
The robot and dock take up a fair bit of space, and it's recommended that you place the dock against a wall, but with enough space either side for the robot to drive into, ensuring it cleans every last bit of your floor. You don't have to do this though, and you can sit the dock in a corner if needed; just make sure the ramp is clear for the robot to drive onto.

Roborock Qrevo Slim review: performance
Handles thick rugs and raised thresholds with ease
Automatic switching between vacuum and mop
Cleans deeply and reliably
Right away, I want to highlight how good the Roborock Qrevo Slim is at driving through thick rugs and over raised doorway thresholds. These are both tasks other robotic vacuums can really struggle with, and even flagship models with four-figure price tags have failed to clamber their way from my exposed-floorboard hallway into the carpeted bedroom.
Not the Qrevo Slim though. It drove over every threshold, every time. It even managed to wade its way through a thick rug in the lounge – something no other robot has achieved reliably – during its first exploratory drive. During that drive it used its camera and imaging sensor to create a map of my flat, which it automatically split into labeled rooms. It got most of the labelling correct, but I still had to jump into the app and make a few edits before saving the map.
Its off-roading abilities meant I could leave the Qrevo Slim to get on with its job, safe in the knowledge that it would drive into every room, clear the rug (and automatically vacuum it, too) and return to base without me checking if it had got trapped. On a couple of occasions, it briefly got stuck on a raised threshold, but always managed to clear it by reversing and driving forward again at a higher speed.
The automatic mode selection also impressed me. Since it's so often a challenge for robotic vacuums, I usually roll the rug up and set a robot to mop and vacuum the wooden floor. But with the Roborock I left it to do its own thing, where it vacuumed and mopped the wooden floor, then automatically raised its mop to vacuum the rug, before lowering it again to continue mopping the floor and ensuring the rug stayed dry.
As well as recognizing the difference between floor types, and where each room ends, the robot can also spot common household items like beds, sofa and television stands, which it then adds to the map.
(Image credit: Future)
On test, the Qrevo Slim's navigation was usually very good, driving confidently into small gaps, not crashing into anything at speed and not getting stuck. But on one occasion it got confused and failed to find its way back to the dock. Understandable if it was stuck under the sofa, or somewhere else far from the charging station, but it was just a foot or so from the dock, yet after lots of spinning around it declared defeat via an app notification. I don't know what caused this, but it only happened once during several weeks of testing.
Onto the specific cleaning tests. I begin by scattering a mix of oats and flour across approximately one square meter of wooden kitchen floor. I began in the quietest, least powerful vacuuming mode, with the robot driving a standard pattern and completing the route only once.
At just 60 dB, Quiet mode really is very quiet indeed, with the vacuuming itself no louder than the motors driving the robot around. As expected, this mode didn't do a particularly good job at picking up debris. It's okay for dust (or flour in this case) but struggled with the oat mix. Just like most other robotic vacuums, the Qrevo Slim's rotating side brush tends to flick debris around the room, and out of the robot's path. Telling it to perform the route twice mostly fixes this, as the flicked debris will be collected on the second pass.
(Image credit: Future)
Turning the vacuum power up to Balanced (one level up from Quiet) and telling the robot to clean the same area twice made a big difference. Despite only being slightly louder (about 63 dB), this setting sucked up almost all of the oat mix, with just a few pieces flicked out of reach by the side brush. Turbo mode is the next step, but at 65 dB it's only slightly louder than Balanced, but clearly has more power and was able to pick up all of the flour and almost every piece of oat.
Max vacuum strength is noticeably louder, at 69 dB. This is when the Qrevo Slim starts to really sound like a vacuum cleaner, but it's still the sort of volume you can talk over with a slightly raised voice. The cleaning power is also ramped up, providing an excellent clean.
However, on this run I noticed how when you create a zone for the robot to vacuum, it won't go right to the edges of a room, even if the zone you create overlaps the walls of the room map. This means you'll be left with a line of debris – in this case flour – swept to within a few inches of the wall but not collected. This is despite me telling the robot to clean right up to the wall. It also frequently failed to clean up directly in front of its docking station. Telling it to clean the whole room fixed this.
Finally, it's time for Max+, which even comes with a warning that it will shorten battery life due to being so power-intensive. This mode peaked at 70 dB and did a great job of collecting the debris, but the routing still meant some oats were flicked across the room and left behind; I also spotted how the robot drove over some flour without the vacuum on, then left a line of white tire tracks that it failed to pick up on subsequent passes. Requesting another clean, on a lower power setting, addressed this.
To summarize, cleaning whole rooms twice using Turbo or Max mode is best in most cases.
(Image credit: Future)
I then repeated these tests on carpet, and saw very similar results. The Quiet and Balanced modes are fine for a little-and-often approach, but failed to pick up all debris. Turbo and Max modes performed better, while Max+ feels like overkill for regular cleaning, but is still a nice-to-have. If I'd just moved into a new home, I'd be using the full 11,000 Pa of suction with Max+ in every room to start with, then switch to Routine or Turbo for scheduled cleaning.
Turbo mode is the best all-rounder, mixing an ability to suck flour out of a reasonably dense carpet, with a low volume level. I still wish the robot was better at collecting debris flicked around by the rotating brush, but this is only apparent when faced with very specific tests. You won't notice this during regular cleaning, but might need to occasionally pick up a few bits of debris with a handheld vacuum.
(Image credit: Future)
Finally, the mop. The Qrevo Slim has a pair of mops that spin at 200 rpm and push downwards for a deep clean. There are three preset water flow options (low, medium and high), plus a custom option where you can pick from a flow rate between one and 30. You can then tell the mop to clean an area once or twice, and pick from four route options, ranging from the quickest, through to Deep+, which is more thorough but takes much longer.
For my test I scattered some hot sauce across the wooden kitchen floor, left it to partially dry, then set the Roborock to work. I asked it to mop the entire room, using a moderate water flow (number 20 of 30), with two cleaning passes, and the Standard route option. In short, it did a great job. The right-hand rotating mop extends outwards, so that it can clean right up against the walls or skirting boards on an initial lap of the room, before tucking back into its default position and working together with the left-hand mop to give the entire floor a thorough wipe.
All of the hot sauce was removed, but only because I set the robot to make two passes; some stains were still visible after the first pass.
The side brush spins slowly during mopping, so it's best to use the mop on a dried stain instead of a fresh spill, as any liquid will be wiped by the brush and require manual cleaning later. It's also worth remembering that the mop uses only warm water and no detergent. (You can find premium robot vacuums that offer hot water mopping, although it's rare – the option to add detergent is more common and is included on other Roborocks, including the S8 MaxV Ultra).
(Image credit: Future)
The mopping process is all very quiet, ranging from 44 bB to 58 dB as the water tank is filled from the docking station, then emptied again, and the mop is cleaned using hot water and dried with warm air. The mop takes three hours to fully dry, but during that time you can ask the robot to either mop again, or do some vacuuming. The dock base (the part the robot sits on while charging) self-cleans with a pair of rotating scrapers, but can also be removed for a manual scrub. After several weeks of testing, the base still appeared as-new.
There's even a sensor in the charge station that checks how clean the robot's water is, then cleans the mops more thoroughly if required.
Lastly, the robot has a voice control system that responds to the command 'Hello Rocky'. It can be asked to 'vacuum the bedroom', 'mop the kitchen' or 'dry the mop', for example. The robot responds quickly and accurately, making voice commands a convenient way to access basic functions without finding your phone and diving into the app for more granular control.
The Qrevo Slim's battery life is a claimed 180 minutes. This feels fairly accurate, but will vary considerably depending on which settings are used.
Performance score: 4.5 out of 5
Roborock Qrevo Slim review: app
Easy to use, but…
Lots of customization on offer. Almost overkill
SmartPlan and homescreen widgets are handy one-tap solutions
The Roborock app works like most other robotic vacuum controllers. There are several customizable cleaning parameters to adjust, including five levels of suction power, three levels of water flow for the mopping function, and the option to clean an area once or twice, plus an option to pick between the standard or faster, more efficient cleaning route. Or, it can be set to only vacuum or mop a certain room or area, depending on your needs.
There's also the SmartPlan, which uses artificial intelligence to learn your cleaning habits and preferences, then creates a customized vacuuming and mopping plan.
(Image credit: Roborock)
On top of all that are the routines. If you don't want to clean the whole map, or a single room, you can instead select the After Meals routine, which can be configured to clean only the kitchen and dining room, for example. Routines appear on the home screen of the app, and can be activated with just one tap. iPhone users can create a homescreen widget with one-tap access to a couple of your most-used routines. With that set up, it's a case of unlocking your phone and tapping once on the widget to start a cleaning routine.
There are even a few pet-friendly app features, including a function where the robot will go and look for your pet without the vacuum running, using its forward-facing camera to show a live stream of what's going on.
(Image credit: Roborock )
As with other robotic vacuum apps, there are options to reconfigure your map and rename rooms. There are also masses of settings to adjust, if you wish, from cleaning schedules, to how the robot uses its lifting mops, what temperature water it uses to clean the mops, how often it empties its dust bin, and much more.
These can almost all be left to their default setting, but I strongly urge pet owners to enable pet mode in the Reactive Obstacle Avoidance page of the settings menu, since this ensures the robot recognizes and avoids pets and their waste with extra precision.
App score: 4.5 out of 5
Should you buy the Roborock Qrevo Slim?
Buy it if...
You have low furniture
It might sound a bit niche, but its lack of height is the defining feature of the Qrevo Slim. It can drive into and clean places other robots can't reach, while the side brush and one of the mops cleverly pivot outwards to clean right up against every wall.
You need lots of power
Despite its more compact design, the Qrevo Slim is currently Roborock's most powerful robotic vacuum cleaner, with 11,000Pa of suction. The most powerful setting consumes lots of power, and is fairly loud, but it does a fantastic job of cleaning carpets and hard floors alike. Much quieter settings are also available.
You want an equally impressive mop
The Qrevo Slim's dual-rotor mop is impressive. Both mops push downwards and spin at 200 rpm, while the amount of water used is highly configurable and the robot automatically works harder on tougher stains.
Don't buy it if...
You're tight on space
Despite the name, this robot is only compact in one dimension – height. The diameter of the robot is still on par with other high-end rivals, and so too is the considerable size of the docking station. A smaller dock is available, but you'll need to be able to plumb it into your water supply.View Deal
You value simplicity
While this robot can function in a simple, one-tap way, to even get to that stage requires a fair bit of setup. There are pages and pages of settings to tinker with, routines to create, a voice assistant to learn phrases for and all manner of configuration, including no fewer than 30 levels of water flow for the mop.
You're on a budget
Although it isn't quite the most expensive robotic vacuum around, the Qrevo Slim is right up there. I think it still represents good value as a premium product, but there are also plenty of options for shoppers wanting to spend less. Roborock itself has the more affordable Q Series, for example.
How I tested the Roborock Qrevo Slim
I set up the Qrevo Slim and used it as my only vacuum cleaner for several weeks. After using it for general vacuuming and mopping duties, I performed a series of tests to appraise its cleaning abilities, as well as its noise levels and how well Roborock's smartphone app works.
Arzopa Digital Picture Frame WiFi 15.6-inch review
The Arzopa Digital Picture Frame WiFi 15.6-inch is an affordable digital photo frame that uses the third-party Frameo app to enable you to easily share your snaps via the frame. Right out of the gate, the first thing you’re likely to notice is that price; while its $149.99 / £169.99 retail price isn’t anything to write home about, during sales season we've been seeing prices around $89.99 / £89.99 – that’s a seriously low price for such a sizeable digital photo frame.
Connecting with the Arzopa Digital Picture Frame is nice and easy. Once you’ve powered it up and connected it to your Wi-Fi, you can scan an on-screen QR code to download the Frameo app. Now, simply press the "Add a Friend" button on the Arzopa’s screen, punch in the code that appears into the Frameo app, and you’re ready to start sharing pics. Even better, you can repeat this step to set up friends and family so they too can share their snaps with your frame.
Not everyone wants to share their photos with the cloud, particularly if they’re security conscious or have young children. If this is you, then the Arzopa’s offline storage will be music to your ears. The frame includes 32GB of internal storage and, should you fill this up, you can easily expand its storage capacity up to 128GB via its SD card port. This does fall short of what some of the best digital photo frames offer, but it still isn't bad, all things considered.
All digital photo frames built on the Frameo app work in the same way and, generally speaking, I’d say this is a positive. The app is easy to use: you can browse your device’s whole image library or just specific albums, adding individual photos or uploading up to 10 at a time. Unfortunately, if you want to upload more than this in one go, you’ll need to upgrade to Frameo+. The cost of this isn't exorbitant at $1.99 / £0.99 a month or $16.99 / £7.99 a year, but you'll need to bear this in mind when calculating if this frame is the right price for you.
As I mentioned in my Pexar 11-inch Digital Picture Frame review, I’m not entirely keen on the way the Frameo app handles cropping images for digital photo frame’s auto-rotate feature. When uploading each image, you’ll set a circular focal area that the frame will ensure remains in frame in either orientation. However, this can still leave some images oddly centered or cropping out details you hadn’t anticipated. I’d rather just have the option to manually set the crop for each image.
(Image credit: Future / Josh Russell)
Once your shots are on the Arzopa, its 15.6-inch display definitely delivers your snaps with impact; the frame feels generously sized compared to many of the other affordable frames out there. Since its 1920 x 1080 resolution is shared over that larger screen estate, pixel density does fall somewhat next to rivals such as the Pexar 11-inch Digital Picture Frame at 212ppi. However, images still look pretty crisp; rendering my macro shot of a bumblebee, the Arzopa frame shows off every grain of pollen and every hair of her fuzzy coat in decent detail.

Unfortunately, where things start to come undone is with color. On my iPhone 16 Pro’s screen, a photo I took of a fireworks display reveals a shower of magenta and violet stars in a glowing pink nebula. But when I uploaded it to the Arzopa, the red and pink hues looked washed out, completely robbing the image of any punch. Similarly, floral shots completely underwhelmed, the lack of vibrancy going far beyond slight variations in color profile to looking actively anemic and poorly shot.
The Arzopa Digital Picture Frame WiFi 15.6-inch does fare better when it comes to black-and-white photography at least. Thanks to its deep blacks and bright highlights, its display is sufficiently contrasty to deliver monochrome landscape and architectural shots with impressive details. The Arzopa frame definitely shows off HDR photography to a high standard.
However, even this bold contrast was slightly undermined by its screen. Perhaps even more than its muted hues, the lack of a matte finish really damages the Arzopa’s performance in bright light. Without any treatment to diffuse incoming light, my photos were always obscured by hard-edged, geometric reflections of the panel lighting in the TechRadar offices; it was almost impossible to ignore since it made it difficult to make out details in the images. Worse, this reflectiveness means the frame is almost certainly unusable in direct sunlight, further restriction its position in your home.
This tendency toward glossiness extends to other elements of the frame’s design. The Arzopa’s frame feels a little cheap and plasticky, but thanks to its black color, this doesn’t feel so in your face. However, the frame’s bezels are much harder to ignore – despite the fact their beveled edges are designed to make them look more like mounting, the white plastic is so cheap-looking and reflective that it does detract from the overall quality of the frame.
Plus, there are other unusual design choices: the frame’s stand is literally just a plastic stick that screws into one corner of the frame. While it seems to do an okay job of supporting the frame in either horizontal or vertical orientation, I’m not convinced it’s sturdy enough to withstand becoming damaged over time.
Buy it on sale, however, and the Arzopa Digital Picture Frame WiFi 15.6-inch is available for an astoundingly good price – and it’s almost certainly better quality than some of the bargain-basement frames you’ll find on Amazon. In terms of crispness of picture, contrast and ease of use, it’s great value for money. However, its muted hues, overly reflective screen and the cheapness of its finish do make my recommendation here equivocal – if you can only find it at a higher price, some of the similarly priced best digital photo frames might make a better choice.

Arzopa Digital Picture Frame WiFi 15.6-inch review: price & release date
MSRP of $149.99 / £169.99 but currently reduced to $89.99 / £89.99
Available now in both the US and UK
Frameo app free or $1.99 / £0.99 a month for Frameo+
The Arzopa Digital Picture Frame WiFi 15.6-inch is available now in both the US and UK.
Its price varies to quite a degree, which has a huge impact on the value you’re getting. At its full price of $149.99 at Amazon US or £169.99, at Amazon UK, it effectively costs as much as the $159.99 / £149.99 Pexar 11-inch Digital Picture Frame, which I'd argue is a much higher-quality frame, thanks to its anti-glare screen and delivery of bold colors. However, some of the sale prices we’ve seen bring the Arzopa frame down to around $89.99 / £89.99, which makes it a far more appealing option, especially if you can’t stretch to the more expensive Pexar.
One other important consideration here in terms of price is the Frameo app. While the base tier is free, to upload more than 10 photographs at a time or videos longer than 15 seconds, you’ll need to upgrade to Frameo+, which costs $1.99 / £0.99 a month or $16.99 / £7.99 a year. That will allow you to upload 100 images at a time, send two-minute video clips, and manage the content on your Arzopa remotely via the app.

Should I buy the Arzopa Digital Picture Frame WiFi 15.6-inch?
Buy it if…
You want a big, crisp screen At 15.6-inches, the Arzopa Digital Picture Frame WiFi delivers a lot of screen estate on which to display your snaps. And while pixel density is lower than the 212ppi of the Pexar 11-inch Digital Picture Frame, photos still look crisp and clear.
You can get it on sale Whether the Arzopa frame delivers good value very much depends on the price you pay for it. Pick it up for the sale price of around $89.99 / £89.99 and you’re getting a very good deal, but you don’t have to spend much more than its MSRP of $149.99 / £169.99 to get a superior product.
Don’t buy it if…
You want your colorful snaps to pop Vibrant hues aren't the Arzopa frame’s forte – colorful subjects such as flowers and fauna can look muted at best, and downright drab at their worst. Fans of black-and-white photography needn’t worry – but if you want your walls to be a riot of color, other frames might prove a wiser investment.
You want to use it in bright rooms The Arzopa’s glossy screen means it's entirely unforgiving when it comes to reflections – whether using it during the day or at night, I found natural and artificial sources of light completely overwhelmed the brightness of the screen. Fundamentally, if it's to sit opposite windows or under harsh lighting, you’d be better off looking for a frame with a matte screen.
Arzopa Digital Picture Frame WiFi 15.6-inch review: also consider
Pexar 11-inch Digital Picture Frame The Pexar 11-inch Digital Picture Frame scarcely costs any more than the Arzopa at full price, at $159.99 / £149.99; however, performance is superior. It offers a 2000 x 1200 resolution across its smaller 11-inch screen, delivering higher pixel density, while colors are far more vibrant. Plus, its matte, anti-glare screen keeps reflected light to a minimum. Read our full Pexar 11-inch Digital Picture Frame review.
Aeezo Portrait 01 If you’re unable to stretch to the Arzopa – or can’t find it at a reduced price – the Aeezo Portrait 01 is a bargain alternative that also includes internal storage and costs just $69.99 / £55.99. You’ll get bolder albeit sometimes slightly unnatural, colors; but the sacrifice is resolution at only 1280 x 800, rather than the Arzopa’s 1080p. Read our full Aeezo Portrait 01 review.
How I tested the Arzopa Digital Picture Frame WiFi 15.6-inch
I tested the Arzopa Digital Picture Frame WiFi 15.6-inch over several weeks. I uploaded a range of photos to it using the Frameo app and connected multiple other people to enable them to share images with the frame, too.
To test the performance of the frame, I uploaded a wide array of portrait and landscape images and included everything from brightly colored shots of flowers and animals to monochrome architectural shots. Additionally, I positioned the frame in multiple places around my home and the TechRadar office and changed its orientation between portrait and landscape.
I have many years of experience taking photos, both on my Canon DSLR and my iPhone 16 Pro and, over the past 15 years, I’ve taken over 40,000 photos. I’ve also spent many years working in print publishing, doing post-production on photos and preparing images for print. This means I have a lot of experience in making images look as close to their source as possible.
