Roborock Q5 Pro+: two-minute review

The Roborock Q5 Pro+ is an affordable robot vacuum that delivers strong vacuuming performance with one major trade-off – poor mopping. Despite having a slightly lower 5,500Pa of suction power, on test I found it excelled at picking up dirt and dust, especially on carpets – perhaps thanks to the dual rubber roller brushes borrowed from Roborock's higher-end models. It also handled the copious amounts of pet hair in my home extremely well. If you don't have loads of cash to splash and your priority is vacuuming, this could be the best robot vacuum for you.

This model uses LiDAR-based navigation, which allows for precise mapping and efficient cleaning paths. Its obstacle avoidance is a little basic, though, so it's one to avoid if you typically have lots of clutter on your floors. Other standout features include the extra large 2.5-liter bag in its compact but efficient dock, and an outstanding, intuitive app.

While the Q5 Pro+ performs admirably well at vacuuming floors of all types, its mopping system is simply comprised of a static mop pad with no mop-cleaning facilities of any sort. Hence, its mopping performance is very underwhelming when compared to much of the competition, including many of its own, admittedly more expensive, Roborock stablemates.

If you don't need mopping, however, this could be an excellent buy. It's slightly older now and discounts are easy to come by, taking the Q5 Pro into the budget price bracket and delivering strong value for money. It's not the latest and greatest model, but it delivers strong vacuuming performance, smart navigation and minimal dust-emptying maintenance. I'd include it amongst the best cheap robot vacuums around and the best robot vacuums for pet hair if you're on a budget.

That's the short version; read on for my full Roborock Q5 Pro+ review.

Roborock Q5 Pro+ review: price & availability

• List price: $699.99 / £499.99 / AU$999
• Launch date: October 2023
• Availability: US, UK, AU (out of stock)

The Q5 Pro line was first announced at IFA 2023, and launched in October 2023. As of writing, the Q5 Pro+ with auto dustbin is available on the US Roborock site at a list price of $699.99, but reduced to $359.99. On the UK Roborock website, it's £499.99 down to £349.99. In Australia, if you go direct to Roborock the Q5 Pro+ costs AU$999, reduced to AU$799 but out of stock at time of writing. The Q5 Pro+ can also be purchased via Amazon, although at time of writing it was out of stock in both the US and UK.

If you don't need the self-empty dock, you can opt for the Roborock Q5 Pro, which is the same model but just with a basic, charge-only dock. That costs $429.99 (reduced to $179.99) or £299 (down to £199.99). In Australia it's only available via third party retailers, but has a list price of AU$899.

At TechRadar, a robot vacuum under $500 / £400 is considered a budget model. At full price, the Pro+ model is mid-range, but it's currently widely discounted into the budget bracket. The Pro version is a budget model even at list price, and really very cheap if you can snag a discount. If vacuuming is your priority, then it's well worth considering.

If mopping is a priority, then it won't be such a good pick, though. In which case, perhaps opt for the earlier high-end Roborock S7 Max Ultra model – which features a fully functioning mop system with self cleaning ability, and can be picked up for around $799.99 / £500 (although at list price it's more expensive),

Shoppers in the UK should also check out the excellent Xiaomi X20+, which retails for a ridiculously low price of £299, and is the best cheap robovac I've tested.

A quick note on availability. Given the rate of new releases in the robot vacuum world, the Q5 Pro and Pro+ are now considered slightly older models. That, combined with widespread discounts and some lack of availability makes me think that maybe this line may be discontinued in the not-too-distant future.

Roborock Q5 Pro+ review: design

• Excellent dual-roller vacuum system
• Great dock with extra large dust bag
• Disappointing mop pad

As much as I tend to gravitate towards Roborock as my brand of choice when it comes to robot vacuum cleaners, I'm also startled by the number of different models – 21 and counting – that the innovative Chinese manufacturer has launched in just the past year alone (at time of writing in March 2025). It's hard enough as reviewer of these little home helpers to differentiate between one model and the next, so I can only imagine the confusion it must cause for prospective buyers who don't know anything about all these models' respective suction power levels, navigation and obstacle avoidance systems, and their various mopping functions.

What I will say is that, though it's not necessarily the best in the Roborock range, if you're on a tight budget and wish to jump onto the Roborock bandwagon, the minimalistic Q5 Pro series is a good place to start. Available in two variants – the Pro+ I'm reviewing here with self-emptying dock and the standard Pro with no dock – the Roborock Q5 Pro+ is one of the lowest priced Roborock series currently on the market.

Robot design

Let's take a look at the robot itself. At 35 x 35.3 x 9.7cm it's about the same width as most robot vacs though, at a shade under 9.7cm, it's also one of the tallest, which means it won't be able to venture beneath some furnishings like its ultra-low stablemates, the Saros 10 and Saros 10R. In the pantheon of robot vacs, this one's not a bad looker, though its ribbed top and black plastic does attract dust instantly. Like within seconds.

Like so many robot vacs these days, the Q5 Pro uses LDS (Laser Distance Sensor) LiDAR and this means that the Q5 Pro will quickly map a home – usually in a matter of minutes – and present its floor plan in great detail on the accompanying Roborock app. LiDAR-equipped robots are excellent at general navigation – even in total darkness – and will almost always find their way back to their docks the very first time you use them, unlike old-fashioned camera-only models that don't know where they are half the time (here's more on how robot vacuums navigate, if you're interested).

This model isn't fitted with a front-facing camera, so obstacle avoidance of any item under around four inches in height will suffer. Instead, it uses its LiDAR and a bump sensor to help it avoid larger obstacles and furniture. While there is a sensor on the front, it's only used for navigation back to the dock.

Like all robovacs, the Q5 pro also comes with four under-body cliff sensors to prevent it tumbling down a flight of stairs (you can also set a virtual barrier in the app for extra peace of mind). The top part of the unit is completed with three instant-access buttons for some manual control – dock, start/stop and spot clean.

This model is fitted with Roborock's very effective Duo Roller rubber rollers for efficient pickup of carpet and hard floor debris, along with the obligatory fixed spinning side brush for sweeping matter from corners of the room into the path of the suction funnel. And speaking of suction, this model is rated at 5,500Pa which is a lot lower than some Roborock flagship models which boast up to 22,000Pa.

However, as you'll see in my tests below, its lower suction power doesn't impinge on the bot's ability to vacuum as well as the very best, especially considering the lower price point. This model doesn't feature an ultrasonic carpet sensor, and while the blurb does say it has carpet boost by default, I haven't heard anything from the motor to suggest it does.

One especially useful asset here is the inclusion of a larger-than-average 770ml internal bin for the robot – most others are around 270ml – and that means it will happily tackle pet hair on a grand scale before it trundles back to the dock to have it all emptied automatically into the dock's also larger-than-average 2.5-litre dust bag. But more on that below.

If you have a big home and are interested in battery specs, you'll be pleased to know that the Q5 Pro comes with a 5200mAh battery – the same as fitted to some of Roborock's earlier flagship models. This battery boasts a running time of up to 180 minutes, which is more than enough juice for a large floor plan.

Finally we come to this model's Achilles Heel – the dreadful moping system. Now I'm generally no fan of any robot with a mopping system and I know I'm not the only one. But, hey, the powers that be have decided that that is what most people want so all manufacturers continue to make high-end robots with mopping systems when all some of us want is a highly efficient vacuum-only system with a whopping 5-litre dust bag instead of the space in the dock being consumed by two large water containers. But what do I know?

So, what's so bad about this model's mop? Well it's a simple 35cm static pad for a start and, worse, it isn't really pushed down hard enough against the floor by the weight of the robot, which means poor contact and coverage. Also, since there are no water tanks in the dock, you will have to fill a tiny 180ml water tank above the mopping pad and select two levels of moisture – a lot and a little. Incidentally, this mop does not raise automatically when traversing carpet so tread carefully if you have a lot of rugs en route to the hard floor. You can read all about the performance of this mop in the, er, Performance chapter below, but suffice to say I wasn't impressed.

Dock design

The Q5 Pro+'s dock is a great bonus since it features an extra large 2.5-liter dust bag where most other bots can only manage around two liters. And since there are no water tanks to accommodate, the dock itself is only around 45cm in height, a svelte 30cm in width and 44cm in depth, which means it won't take up very much floor space.

The ribbed design of the dock's front fascia is reminiscent of some of iRobot's newer offerings and it's no shabby looker, especially when compared to some of the tasteless designs I've recently seen. However, I'm not too enamoured of the cheap-feeling lid one has to lift to access the dock's dust bag. Also, setting the dock up isn't quite as straightforward as most models since you will need to assemble the dock by using the supplied Allen key (under the platform) to attach it to the bin housing.

Roborock Q5 Pro+ review: performance

• Excellent vacuum performance
• Strong navigation but rudimentary obstacle avoidance
• Very poor mopping

Let's take a look at the Roborock Q5 Pro+'s performance. It's a bit of a mixed bag here, so I've broken this section up into navigation, vacuuming and mopping so it's clear where this bot's strengths and weaknesses are.

Navigation performance

All Roborocks navigate spaces extremely well and this model is no different. No it doesn't have the bells-and-whistles multi-point LiDAR navigation of the new Roborock Saros 10R, but it managed just fine in my open-plan home. Put another way, during my review period it never once got lost or found itself trapped under furniture. I'm not promising that'll never happen in the future – it's a robot after all – but it's a strong start.

Roborock uses something called Adaptive Route Algorithms for the Q5 Pro's navigation system and this means it will clean floors in a logical, linear way rather than randomly like most camera only-based models.

Crucially, this is another one of those modern bots that didn't seem to have any trouble traversing my rugs, even those of the loose, thin variety. And that's always a major bonus in my opinion.

This model can be described as merely adequate when it comes to obstacle avoidance, so it's best suited to homes that are generally free of small items like loose socks, Lego bricks and phone cables. If this describes your home, you would be better off spending a lot more on a higher-end model – or avoid a robot altogether.

The Q5 pro uses very basic touch-and-run avoidance. This means it may gently push some larger items out of the way while dodging others. There's no rhyme or reason to its thought processes when faced with obstacles but, according to my tests, it didn't seem to see any items less than around 4 inches in height. Consequently, it gamely ploughed over the small nylon dog bone that has similarly caught out many other robot vacs and pushed some smaller dog toys that other models have avoided.

Vacuum performance

Vacuum cleaning of both hard floor and carpet is where this model really shines. But then that doesn't surprise me because very few Roborocks fail to impress in this regard.

Test one took place on my kitchen floor with a buffet of different ingredients – a handful of orzo pasta, a crushed Hob Nob, half a teaspoon of brown sugar, a large pinch of flour and a scattering of cornflakes (I would usually also include some oats, but I ate them). Anyway, I set the unit to Max (one below full power) and selected two passes.

The results were excellent; indeed, as good as many of Roborock's high-end bots. Yes, there was some serious snow ploughing of ingredients (my bad for adding so many) but everything was eventually sucked up with no traces of any remnants. Top marks.

I then replicated the test on a medium-pile carpet rug using the app's Zone option and set the vacuum power to Max+ (its highest setting) plus two passes for good measure. I expected poorer performance for this test but was pleasantly surprised to see it collect the vast majority of the debris in a single pass. It then came back on itself and collected the rest. And just for good measure, it then proceeded to run over the same section horizontally until absolutely nothing remained. I call that a success.

Aside from the above tests, I also had the Q5 Pro running over a five day period and noted how well it collected all the hair shed by my two dogs and three cats. The great thing about this model is that it has a much larger internal bin than the majority of other robot vacs. This is a big bonus when it comes to collecting pet hair – not because it can cram more in during an average cleaning session, but because of the extra space in the bin which prevents bundling and compression when automatically emptying at the dock.

Many robot vacs I've tested have occasionally had issues during self emptying, where large clumps of hair become trapped in the outlet of the robot's bin and around the intake to the dock's dust bag. These issues are easily fixed but are also an inconvenience. Hence, if I'm in the same room as the dock, I always listen for the tell-tale ‘woomph' sound as the hair is sucked into the dock. In fact, I've also become accustomed to the tone of the motor fan during emptying so I can usually tell if there's a blockage issue.

Mopping performance

In short, there is nothing Pro about this robot's mopping system. In fact, I'm not sure why Roborock even considered a mopping system like this in this day and age, because it is pretty woeful at mopping up anything other than the very top layer of dust and some very light soiling. Worse, the mop cannot lift itself off the floor when crossing carpets so you would need to remove all rugs while in transit.

To set up the mopping system you need to fill the small 180ml water tank – preferably with hot water – and slide the switch under the mop pad to your preferred choice of wetness (I chose the lower amount since I have engineered wooden floors). Now wait a few minutes while the water saturates the mop and set it off on its way. Since the app doesn't show an option for mopping, you basically set the robot to do a standard vacuum and the mop pad simply drags along the floor.

In my test, the pad left a lot more moisture on the floor than other mopping models I've tried and, because some of my floor's wooden planks are fractionally bowed, the water was deposited as a series of stripes. Yes, it kind of mopped the floor as evidenced by the dirtiness of the mop but, really, this is no substitute for some proper elbow grease. Worse, you have to remove the mop pad when finished and clean it under a hot tap. That's just too much work for me.

Personally, I wouldn't bother using this model as a wet mop. Instead I would advise leaving the dry pad attached when sending the bot out on a vacuum run. It'll simply drag behind, collecting any remnants of dust while giving your hard floor a polish of sorts.

Alternatively, if you don't think you need a mop, perhaps consider the non-mopping Q5 Max+, which is ultimately a better overall choice for the money. And if your robot simply must have a mop attached, consider something like the Roborock S7 Max Ultra which, while more expensive, is way better at wet mopping hard floors.

Dock performance

I've been very impressed with the performance of this dock. For a start, it's got a much larger dust bag than most other models (2.5-litres) and a reassuringly loud suction process that never failed to remove all contents from the robot's larger-than-average bin, even when filled with pet hair. I also love its unobtrusively small size, which makes it perfectly suited to location in a living room if space is an issue.

It's not as fully-featured as you'd find on pricier models – as discussed, there are no water tanks, let alone mop pad cleaning – but as a dust-emptying dock it's excellent. Despite some cheapness in the quality of the lift-off dust bag lid, I give this dock close to top marks.

• Performance score: 3.5 out of 5

Roborock Q5 Pro+ review: app

• Intuitive and easy to set up
• Feature filled
• Not all setting options available

The Roborock app is essential for maximizing the Q5 Pro+'s potential. Setup is straightforward and the interface is clean and very intuitive. It also comes with tons of options, though some may be missing for this particular model of robot vac.

In general, you're provided with a decent range of parameters, including real-time mapping, cleaning schedules, zone customization, routine settings and various custom options regarding how the robot and dock behave during any cleaning session. I particularly appreciated the ‘no-go zones' for keeping the vacuum away from delicate areas and the way you can view your home in 3D. I also love the way you can set its voice notifications to your specific language and, if living in the UK, even choose a British accent.

How I tested the Roborock Q5 Pro+

I let the Roborock Q5 Pro+ loose on my open-plan flooring and observed its behavior over a five-day period. I then ran a series of intensive tests to see how well it vacuumed both hard floor and carpet, which it passed with flying colours. I also tried out its obstacle avoidance using a variety of items, including small and large dog toys. I then put its mop to the test, knowing full well that it would be a sub-par performer simply by looking at it. And I was right.

Yeedi M12 Ultra Plus: two-minute review

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.

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.

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.)

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.

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.

Yeedi M12 Ultra Plus: alternatives to consider

How I tested the Yeedi M12 Ultra Plus

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.

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.

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.

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.

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.

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 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.

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.

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.

• Performance score: 3.5 out of 5

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.

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.

Roborock Qrevo Slim: two-minute review

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 specs

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 navigate for a deep-dive into this area.)

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.

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.

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

Roomba Combo Essential: two-minute review

The Roomba Combo Essential is a basic, budget robot vacuum that's designed to be effective, yet simple to use. iRobot bills it as a good choice for recent graduates, new homeowners, or anyone unfamiliar with the world of robot cleaners, while also being a worthy replacement for the Roomba 600 Series – an ultra-popular budget range that launched in 2012 and which is no longer available to buy. I put it the Combo Essential to the test, and while I've found that it can't begin to compete with the very best robot vacuums on the market, it compares pretty well to today's best cheap robovacs.

It arrives with a list price of just $274.99 / £269 / AU$499, but the current Black Friday deals mean it can be picked up for much less. Regardless, even for its listed price, the Roomba Combo feels well made and good quality, and for cleaning performance it's solid, too. The bot tackled light vacuum cleaning without issue, and when bumped up to Max suction mode it cleared both small and large debris tests pretty effectively. Even more impressive was the mopping facility – which proved more efficient than other, far pricier robovacs I've tested.

When it comes to customization options, you're limited: essentially, you can pick from three suction levels and three water levels; choose either a vacuum-only or combination vac-mop run; and opt for either a spot clean or a whole-home clean. More advanced alternatives will let you clean a room or area, and auto-adjust suction when moving from hard floor to carpet, for example. The lack of No-Go Zone option means you'll also need to manually block off any soft flooring areas when running a combination vac-mop run, or you better believe it will attempt to mop those carpets for you.

Mapping, too, is basic – I'd politely describe the general behavior as "erratic". You're also limited in what you can achieve remotely. You can pause or resume cleaning; but the app doesn't offer a return to dock option, for example, in the even the bot ends up doing something that it shouldn't during a cleaning run – and based on my experience, this could happen. This does mean that it's probably best to avoid setting the Roomba Combo off on a clean unsupervised, which is a little annoying since most folk are likely to prefer to have their robovac complete duties while they're out of the house, for minimal disruption.

Note, too, that there's no option to add an auto-empty dock, which will result in an irritating amount of manual emptying if you have pets or a large, high-traffic household. However, for small homes, emptying is perfectly manageable and the tiny, charge-only dock is actually a benefit. (Note: the newer, similar Roomba Combo 2 Essential does have an auto-empty dock).

Despite having had a somewhat frustrating time testing this spirited little robovac, I'd still actually recommend it to some people. If you have a small home and just want to do whole-home cleans once or twice a week, the Roomba Combo will perform just fine. The small dock won't get in your way, and if you're happy to manually empty it every couple of weeks, then it could be a major time- and effort-saver for very little outlay. That's the short version; read on for my full Roomba Combo Essential review.

Roomba Combo Essential review: price & availability

• List price: $274.99 / £269 / AU$499
• Launch date: April 2024
• Available: US / UK

The Roomba Combo Essential robot is widely available around the world. It comes with a list price of $274.99 in the US, £269 in the UK and AU$499 in Australia, but I've already seen it discounted heavily – at time of writing, the Black Friday robot vacuum sales are in full swing, bringing the price down closer to $150 / £150.

Even at the list price it's in the budget bracket, and performance is roughly what I'd expect at that price. You don't get the extensive features and hands-off dock functionality of pricier bots, but build quality is good, and there are some thoughtful design features. As a basic model it offers decent value for money, especially if you can snag a discount.

Roomba Combo Essential review: design

• Combination vacuum and mop with a low-profile design
• Basic charge dock; no self-empty features
• Single bristle roller rather than iRobot's usual dual rubber rollers

The Combo Essential is a combination model, which it offers vacuuming and mopping capabilities. Many (pricier) robovacs have a raised central puck to house a camera; because the Combo Essential comes without, it has a relatively shallow profile, enabling it to clean under low furniture without issue.

There are three physical buttons on the bot itself: a Clean button (with power icon) to start, pause and resume cleaning tasks; a Home button to send the Roomba Combo back to its dock; and a Spot Clean button for tackling small, targeted mess. On other robovacs I've tested, these have been superfluous; but on the Roomba Combo Essential, I did find myself having to use them fairly regularly (more on that in the Performance section).

Flip the bot over, and you'll find a V-shaped bristle brush. It's described as "multi-surface", so presumably built for use on both hard floors and carpet. This is the only Roomba to not feature iRobot's patented dual rubber rollers. These rubbery rollers are excellent at pulling hair and debris from carpets, so I was interested to see how this alternative design compared. There's the usual triple-pronged edge brush, designed for tackling dirt at the edges of rooms.

Annoyingly, iRobot refuses to release its suction stats, arguing that other design elements also play a part in the overall effectiveness of a robovac's dirt pick-up. While that is true, a figure in Pa does provide an easy point of comparison when sussing out your various options.

What I do know the Roomba Combo offers the same "standard" cleaning offered by the majority of other Roombas (bar those right at the top of the range), and that it has 18x more suction power than the Roomba 600, which perhaps isn't surprising given that series launched in 2012. You can select from three different suction levels in the app.

Housed at the back of the robot is a removable section that includes both the dust cup with filter and the water reservoir. This is very well designed, with a brush/slicer tool clipped in, for clearing any stuck debris from the bin, and removing tangled hair from the brushroll. The inlet for the water reservoir is found beneath the rubber stopper bearing a water droplet icon.

The mop is a D-shaped microfiber pad. These are pretty common (even on far pricier models), although I tend to find dual, spinning mop pads do a better job of scrubbing. Some budget models simply drag a wet wipe across the floor, so the Roomba Combo's offering is at least a big step up from that approach. In fact, I was pretty impressed with this model's mopping capabilities, but I'll get into that in more detail below.

The mop pad is fed from the small onboard water tank, and there are three water level options, which you set manually. This robot can vacuum and mop simultaneously, thus taking care of your hard floor cleaning in a single pass, although I probably wouldn't recommend doing this.

Some more affordable Roombas, such as the Combo j5, require you to manually swap over the whole back plate when you want to change from vacuuming to mopping. Here, the tank stays in place; but if you want to send the bot on a vacuum-only run (or avoid damp carpets), you'll need to remove the mop pad. It clips on easily, on top of where the bin and water tank sit.

The dock is a minimalist unit that simply charges the bot. In fact, it's teeny-tiny compared to other robovacs I've come across. Most pricier Roombas have the option of adding a more advanced base (sold as "Plus / +" versions) – the simplest of these just empties the bot's small dust cup into a larger one in the dock, while the most advanced options can also refill the water tank and wash/dry the mop pads.

There are no alternative dock options here, so you'll have to take care of all that maintenance manually. For people like me who have a small home, that's a worthwhile compromise not to have a bulky dock cluttering up the space. However, if you have a large home with lots of people traffic, or pets, it's probably worth choosing an option that can be used with a self-empty dock, to save you the hassle of constant manual emptying.

One minor complaint is that I found the cable a little short (41in / 105cm long). That, together with the requirement that the dock sit on a hard floor and have half a meter of clear space either side and 1.2 meters in front (this is pretty normal for a robovac dock) meant I had to get an extension lead out. There is a cable tidy at the back of the dock to prevent the bot becoming tangled in any spare cable on its travels.

Setup was straightforward, simply involving removal from the packaging, snapping on the side brush and mop pad, plugging in the dock and charging. There are clear instructions in a booklet, plus a QR code to download the app, and a further one to link the bot to your app. This app then walks you through the final stages of getting ready to clean, before (in my case) launching a software update.

Since the Combo Essential works on a 2.4GHz network, the official advice is that you'll need to make sure both the bot and your phone are also on 2.4GHz Wi-Fi during setup. After that, you can switch back to 5GHz, if you have it. However, I thought I'd try setting up my bot without changing the settings on my Wi-Fi and it managed just fine.

This is a more basic model, so don't expect a long list of smart features. It's powered by iRobot OS, promises up to two hours of cleaning on a single charge. It can be controlled via the iRobot Home app or with your voice, provided you have an Alexa-, Siri-, or Google Assistant-enabled device.

Roomba Combo Essential review: performance

• Decent vacuuming, surprisingly good mopping
• Erratic behavior
• Requires more manual involvement than most

Having set up and charged the Roomba Combo Essential, I set it off on a whole-home vacuum of my one-bedroom flat. This did not go very smoothly. On the first run, the bot bumped its way around a bit before finally becoming stuck in a cycle cleaning back and forth in front of my fireplace (there were zero obstacles preventing it from leaving the area).

After around 25 minutes or so completing this same short route, I decided to send it back to dock to try again. There was no option to send it back to the dock via the app, so I had to press the button on the machine itself. On its way to the dock, it took a detour into my bathroom for the first time, and simply stopped there – again, for no apparent reason. A second attempt at a full-flat clean yielded slightly better results, but still far from perfect.

After the initial mapping process was as complete as I could hope for, I started with our standard vacuuming tests: a sprinkling of oats and (separately) blitzed up biscuit crumbs, sprinkled on the floor, to see how the robotic would cope with fine and chunky debris.

I started on carpet, using the Spot Clean function and the medium vacuuming setting. The Roomba Combo Essential flicked around a fair bit of debris, but sucked up most of the spillage on the first go. I then bumped up the settings to maximum suction, and ran the test again, after which there were only a few remnants remaining.

On hard floors the bot's performance was a little better. Still a fair bit of flicking mess around, but medium mode was enough to pull up most of the debris on the first pass.

In fact, the issue on hard floor wasn't so much with suction but navigation. On carpet, the Roomba Combo made its way out from where I had placed it in a neat outward spiral shape, thus gathering most of the debris on its travels. However, on my lino floor, for seemingly no reason, it decided to adopt an arc-based route. As a result, it was tricky to get it to even pass over the debris.

Since there's no auto-empty, you'll need to manually empty the onboard dustbin. This mechanism is straightforward, and feels well designed, with chunky clips to detach the bin. If you're cleaning a relatively small home (and don't have pets), this isn't too much hassle.

When you want to mop, you'll need to attach the mop plate onto the bot. This is simply a case of clicking it into place. iRobot suggests dampening the mop pad before attaching it, for best mopping results. You'll also need to fill up the onboard water tank before you launch any "combo" job. If you try to launch a vacuum-only task, it will helpfully inform you that the mop pad is attached.

iRobot suggests removing rugs before launching a combo run, and you'll also need to physically block off any areas where you don't want the bot to venture with its mop. I don't have a door between my (lino) kitchen and (carpeted) lounge, so I had to create a physical barrier before each combo run.

I had low expectations for the Roomba Combo Essential's mopping skills, but I was pleasantly surprised. Again, navigation was erratic, but I could see from the damp stripes on my floor that it was doing an efficient job – in fact, better than some far pricier robot vacuums I've tested.

My only real complaint was that it really tried hard to escape into my carpeted lounge – if you don't have doors you can close, you'll need to be prepared to put some sturdy barriers in place.

I also tested to see how well the Roomba Combo Essential coped with sticky mess (tomato ketchup) and liquid mess (apple juice). It sucked up the juice with no issues, and smeared the ketchup about a bit; but ultimately, after a couple of passes, the robot vacuum had cleared it.

Having said that, I wouldn't actually recommend using a robovac on spillages such as ketchup, because the condiment will get on the wheels and track around the house. Here, it ended up on the tracker wheel, which isn't removable and thus proved a pain to clean.

This robovac vacuums and mops at the same time, but I'd actually recommend running over surfaces in vacuum-only mode first. I did my combo run while there were still remnants of the vacuuming test on the floor, and it ended up in a disgusting gunk in the dust bin.

In general, it's worth stating that no robot vacuum will do as good a job of mopping as a manual mop option. They're really just for light cleaning, and for this, I found the Roomba Combo Essential more than adequate.

After each combo run, you're advised to empty the water tank of any unused water, while also rinsing the mop pad and leaving it to dry. Since there's no spare pad included, you'll need to make sure you have time to do this (spares are available to buy via iRobot, alongside other replacement parts). It's machine-washable for occasional deeper cleaning.

• Performance score: 3.5 out of 5

Roomba Combo Essential review: app

• Well designed, but limited options
• Can't do some basic things remotely
• Compatible with popular voice assistants

iRobot's companion app is well designed and intuitive. It offers only basic customization / control options: essentially, you can choose from three vacuum and three mopping modes, and you can choose to vacuum-only or combo vac-and-mop. Pricier models offer far more control over what they clean and how they do it.

After a task is complete, the app will provide a time summary of recently completed tasks and an outline of its journey. You'll need to figure out where the bot has and hasn't been from just a shape – there's no labelling of rooms here. That's expected at this price point, but I do struggle to understand why iRobot has opted an almost impossible to see yellow/green color for said maps.

There are limits to what you can achieve remotely. You can start and pause cleaning, but there's no return to dock button. As such, if you need to cut a job short for whatever reason, you'll need to find the bot and press the button on top. For spot cleans, you'll need to manually pick up the bot and take it to the bit that needs cleaning, then press the Spot Clean button.

You can't instruct the bot to clean just one room, and because no-go zones aren't an option, if you want to stop it from going somewhere, you'll need to physically restrain in (using doors).

There is a Clean While I’m Away automation option, where the bot will automatically start cleaning when you leave the house – although, personally, I wouldn't leave this bot to clean unsupervised. Finally, the app offers suggested schedules based on previous jobs.

Roomba Combo Essential review: alternatives

Within the "cheap Roomba" remit, there are a few options. If you want to see what you could get if you shelled out a little more, my Roomba range guide should help.

Roomba Vac Essential

In some countries, including North America, there's a vacuum-only model called the Roomba Vac Essential. This is very similar to the Combo Essential, but without any of the mopping capabilities. However, it isn't available direct from iRobot and can be hard to find elsewhere now, too.

Combo 2 Essential

In October 2024, iRobot added the Roomba Combo 2 Essential robot + AutoEmpty dock. The big difference compared to the original Essential is that it has an auto-empty dock, which will be a big benefit for those dealing with high levels of dirt or hair. It also apparently has "2x the cleaning power of the original Essential series". No specifics are given on this, but note that it's not "twice the suction power", so I'm thinking probably design tweaks. It also has an improved bumper design, and the ability to recharge and resume during cleaning missions. In short, a better choice for bigger homes and higher dirt levels.

How I tested the Romba Combo Essential

• I used it for a week as my regular vacuum
• I ran specific vacuuming and mopping tests
• I tested the app and any special features

For this Roomba Combo Essential review, I used this model as my main vacuum for a week. I ran the standard TechRadar suction and mopping tests, seeing how well it coped with fine debris (cookie crumbs), larger debris (oats), wet spillages (juice) and sticky spillages (dried tomato ketchup). I also noted how well it coped with my collarbone-length hair on its travels. I tested the spot clean function, mapping, and general usability.

Dreame L40 Ultra: two-minute review

With its blend of impressive suction power, rotating mop pads, expert navigation and obstacle avoidance, self-cleaning ability and smorgasbord of AI and software features, the Dreame L40 Ultra is a solid hybrid vac-and-mop system for those looking to simplify their home cleaning regime. In fact, it's one of the best robot vacuums I've tested.

Equipped with advanced LiDAR navigation, the L40 Ultra efficiently and very quickly maps your rooms, cleans in precise patterns and is better than average when it comes to dodging obstacles. With its ample suction power (up to 11,000Pa – up there with the highest you'll find anywhere), the L40 Ultra handles dust, pet hair and small debris very efficiently, whether it's on hardwood, tile or low- to medium-pile carpet. It mops exceptionally well, too.

Personally, I would always recommend opting for a robot model with a self-emptying cleaning system, especially if you have pets. Well the L40 Ultra's dock not only automatically empties the robot's tiny onboard bin but it washes its mops, too, and then dries them using warm air. No, it's not the prettiest looking cleaning station in town but it is equipped with oversized water containers and a much larger dust bag than much of the competition. And that means you'll spend less time doing maintenance.

You can read more about the Dreame L40 Ultra below but, if you're in a rush, take it from me that this model is well worth the investment if you're looking for a competent, reliable and mostly fuss-free hybrid bot to perform the mundane tasks of keeping your floor spaces in tip-top condition on a daily basis.

Dreame L40 Ultra review: price & availability

• List price: $1,499.99 / £999
• Launched: October 2024

Available in white only, the Dreame L40 Ultra comes with a list price of $1,499.99 / £999 (although when it first launched it was cheaper, at $1,249.99 / £899). Even though that puts it in TechRadar's premium price bracket, I think it still represents strong value for money.

The L40 Ultra sits just below the company's flagship X40 Ultra, which costs around $350 (£250) more, mostly because it comes with an extra laser for improved obstacle avoidance.

In terms of other brands' offerings, it's very comparable feature-wise to the Qrevo Master ($1,200 / £949) from Roborock (another Xiaomi-linked company), which sports roughly the same level of suction power and very similar onboard tech, including an extendable side brush arm and rear mop for precise edging.

You can buy direct from Dreame, or head to a third party retailer like Amazon. Seasonal shopping events always include strong robot vacuum deals, and the Black Friday sales can be a particularly good time to shop.

Dreame L40 Ultra specs

Dreame L40 Ultra review: design

• Superb vacuuming and mopping features
• Full self-cleaning dock
• Large, jarring clean base

Backed by Chinese behemoth Xiaomi, Dreame is fast becoming a major player in the ever-expanding arena of robot vacuum cleaners and robot mops, and this high-end hybrid model comprising a 2-in-1 vacuum and mopping system is a sterling example of just how much attention to technical detail the company applies to its products, especially when it comes to features, navigation and onboard smarts. In fact, there are many similarities between the L40 Ultra and class-leader Roborock's premium Qrevo Curv and S8 MaxV Ultra models, only this one's for affordable to buy.

Before I get down to the nuts and bolts, I should address the elephant in the room – namely the size and design of the L40 Ultra's charging dock-cum-cleaning station. This white-only model's dock is 59cm in height, 41cm in depth and 34cm in width, and it's clad almost entirely in plastic that attracts pet hair and dust like a cowpat attracts flies. To break up the monotony of so much white, the L40 Ultra also comes with a blingy, rose gold-tinted dustbin cover that some users may actually like. I don't.

Moving on to the robovac itself. Let's start with the little side rotating brush that all robot vacs are equipped with to fling any debris that sits outside of their chassis into the path of the main brush roller. In the vast majority of models the brush is fixed in position and its bristles can only stretch an inch or so beyond the machine's bodywork, which makes cleaning right-angled corners near impossible.

Well, like some of the top end Roborock models, this one is equipped with an articulating side brush mount that pops out on an arm by a few inches so the spinning bristles can reach deep into corners. This is a game-changer because it means you might not need to reach for a hand vac to finish the job. Also, unlike any other model I've tested, this one's side brush doesn't engage when on carpet and that means its bristles will last longer and will be less likely to snag on a rug tassel or wrap itself in a wayward shoelace.

The same thing applies to the L40 Ultra's mopping system, which uses two magnetically attached circular spinning mops on the rear that do an impressive job of keeping hard floors dust- and stain-free. Like Roborock's flagship models, the L40 Ultra's right-hand mop automatically protrudes beyond the chassis by several inches when the device is cleaning around chair legs and along skirting boards. But more than that, this model's mops are automatically ejected and left behind in the base station whenever the bot is out on a vacuum-only run.

Yes, the L40 Ultra's mops will retract when on carpet by 10.5mm, but the thinking behind this particular system is that it's better for any carpet that the bot may need to cross en-route to a vacuum-only session to not have any mops fitted at all. And so it leaves them behind in the dock, just in case. After all, you ideally don't want any dirty wet mops possibly touching the fibers of your favorite deep-pile rug lest they leave some unsightly marks.

Like most modern hybrid units, the L40 Ultra's dock not only charges the robot's ample 5,200mAh battery between cleaning sessions, it also sucks debris from the robot's tiny 300ml bin into a much larger 2.3-liter dust bag. This should happily last a month or two before needing to be disposed of, unless, like me, you have a menagerie of hairy pets.

Because this model also mops, it has two huge water tanks – 4.5 liters for the clean water and an equally voluminous 4 liters for the dirty stuff. I should also add that this model ships with a small 200ml bottle of Dreame-branded floor cleaning solution, which you pour into a separate reservoir next to the dust bag section. This solution is then added to the water that's pumped into the robot's small water tank before it heads out on a mopping run. Like all similarly styled premium hybrid robot vacuums, the L40 Ultra's mops are automatically cleaned in the station on its return and then dried using wafts of warm air.

The robot itself uses LiDAR, an RGB camera, sensors and AI to help it map and navigate around the home, and it's one of the very best systems this writer has so far come across. Its initial mapping run was not only fast but exceptionally accurate, too. In fact, it was the first bot to accurately divide my downstairs open-plan flooring into four separate rooms where others have either joined two rooms together or made the entire ground floor one large room. Incidentally, the same LiDAR, sensor and camera set up is also used to detect obstacles, and very good it is, too. You can read more about my obstacle testing in the Performance chapter below.

One of the biggest issues I have with robot vacs is the propensity of loose rugs I have in every room, and rugs are the robot vac's arch nemesis, especially if they're not fixed down with some of that sticky stuff IKEA sells to keep rugs from slipping on hard floor. Well I'm pleased to report that at no time has the L40 Ultra snagged itself on any rug tassels or ruffled up any rugs while traversing them. I put this down to some extra height at the front of the unit that allows it to ride over almost any rug, no matter how thin and slippery it is. Top marks in this regard.

For some reason, most robot manufacturers still insist on producing circular bots instead D- or square-shaped models. As a result, the main suction area on this model is positioned between its two side wheels with 9cm or non-suction space on either side of its single rubber roller. This is normal for most bots and invariably why they are equipped with a side brush to fling wayward matter into the path of the suction roller. And speaking of suction, this model produces 11,000Pa of power, which is above average and more than enough oomph for hard floors and all but the deepest of carpet pile.

Unlike Roborock and a few other manufacturers that equip their bots with two rubber brush rollers that run in tandem, this model has just one 17cm roller. Nevertheless, I haven't seen any significant reduction in dust collection as a result of having just one. As an added bonus, this model also ships with what Dreame calls a TriCut Brush, specifically designed for cutting loose hair so it doesn't bundle together and block the main suction tube in the cleaning base when it's drawing debris from the robot's bin. It's worth fitting this replacement roller if you have cats or dogs of the shedding variety.

You get ultrasonic automatic carpet detection and five levels of vacuuming power with this model – Quiet, Standard, Turbo, Max and Max+ – and a sliding scale of mop wetness depending on how dirty your hard floor is and whether it's tile, vinyl or delicate wood. I always set vacuum power to either Turbo, Max or Max+ for full efficiency and, because I have engineered wooden floors, somewhere in the middle of the moistness chart when mopping.

Robot vacs of this nature are usually really easy to set up and this one is no different. Simply remove the dock and robot from the box, place the dock somewhere with good access to all your rooms and fill up the fresh water tank (the dust bag is pre-fitted). Next download the Dreame app (iOS and Google), tap the plus sign, select the L40 Ultra and follow the on-screen instructions. A voice assistant will chip in with odd vocal announcements during both setup and day-to-day use, and it goes without saying that this model will also respond to your own voice commands if that is your wont.

Dreame L40 Ultra review: performance

• Excellent vacuum skills
• Decent mopping, too
• Impressive self-cleaning dock

The model Dreame L40 Ultra is an excellent navigator and a stalwart performer when traversing loose rugs. But how well does the L40 Ultra actually clean? Well, if the contents of the dock's dust bag are anything to go by, I'd say it's a winner, especially at collecting the wayward dog and cat hair that my home seems to be engulfed in.

In fact, I can often hear that reassuring whoomph sound as another cardigan's worth of hair is being sucked out of the bot's bin and into the dock's larger-than-average dust bag. What's more, this bin-emptying sequence isn't too loud either. This, alongside the TriCut Brush feature, means I'd rate the L40 Ultra amongst the best robot vacuums for pet hair.

I have no issues to report regarding this model's efficiency at collecting dust and debris whether it's on my hard wooden flooring, the especially hairy carpeted rug sitting in front of my dogs' bed or the entire floorspace of our village hall. It just heads out, cleans the edges first before embarking on systematic parallel lines for the rest of the room and then returning to its dock like clockwork. You can even adjust the frequency with which it returns to its dock to empty the bin.

I've been especially impressed with how well the L40 Ultra has tackled our large village hall. After mapping the 110 square meter area in about seven minutes, it then proceeded to start cleaning the edges and under any tables and chairs before sweeping the main floorspace in perfect parallel lines and what's more, in the direction in which the floorboards were laid. Granted it seemed to skirt around three small areas for some bizarre reason but I still call it a great success.

To date, the L40 Ultra has held enough juice to vacuum the hall's entire floorspace in one fell swoop, while in Turbo mode. That's a remarkable statistic. It took 95 minutes to complete what I consider a huge task for any robot vac with an amazing 54% of battery power still remaining.

The same level of efficiency applies to its mopping system, which is better than any static pad-based moppers out there. No, it won't replace a mop and bucket (or one of the best wet-dry vacuums) for rapid stain removal, mostly because it's too much hassle commanding a robot to mop a specific area that's only a few inches square.

By the time you've opened the app, selected a rough zonal area and waited for the bot to get there, you could have reached down with a damp paper towel and cleaned it up in a thrice. Nevertheless, I did perform such a test on a dried soy sauce stain and was impressed by how well the L40 Ultra dealt with it in three short passes. I put that down to those spinning mops and the downward pressure exerted on them.

Of course, the idea with robot mops is that, if scheduled, they will ensure that any hard floors are kept clean and tidy on a regular basis – and in this case right to the very edge – without any need for reaching for a wet mop, tea towel or paper toweling.

For most of my review period, I generally let the L40 Ultra use its CleanGenius method which purportedly uses AI to identify particularly grubby areas for extended cleaning. I mainly set different vacuum-only and mop-only schedules, even though the bot will happily perform both methods of cleaning during the same time frame. And as I've mentioned above, if performing a dual vac-and-mop function, the L40 Ultra's mops are raised by a couple of centimeters whenever it's crossing a patch of carpet and, if vacuuming only, it will leave the mops in the charging dock.

Obstacle avoidance is a key element when it comes to robot vacs because the last thing you want is a jammed up robot sitting there doing nothing while you're out and about. I give this model almost full marks for obstacle avoidance, though I wouldn't trust it with avoiding dog mess or some items below about two-inches in height.

I noticed this when I laid out an obstacle course comprising a trainer with wayward laces, a neck buff, a woolen glove, a small dog toy and a phone cable. Amazingly, the L40 avoided the trainer and its two extended laces, the neck buff and the phone wire in three different tests. However, it pushed a small soft dog toy forward on two occasions and rode over the glove, thankfully without it jamming up the suction roller.

Hence, like most robot vacs, this model is not infallible when it comes to items less than about two-inches in height. And that means I wouldn't want to trust it with dog mess of any variety. Other than that common anomaly, I give this bot full marks for performance.

• Performance score: 5 out of 5

Dreame L40 Ultra review: app

• Easy to navigate
• Good customization options
• Could be improved here and there

While you can perform two very simple commands – clean and return to home – by tapping two buttons on the robot itself or by shouting ‘Hey Dreame, clean the kitchen' and the like, the vast majority of setting up and customization must be done via the Dreame app, which you can download to your phone for free from Google Play or the Apple App Store.

The Dream app is very reminiscent of that from Roborock and it's very well thought out and easy to navigate. However, there are some elements I'd like to see improved, especially zone cleaning – which doesn't save the command for later use – and the ability to set routines along with daily schedules. That's what I love about the Roborock app. It allows me to create a bunch of manually programmed routines and specific zone cleaning regimes and it saves them all for instant recall from the home page of the app.

On the plus side, the Dreame app lets you see the entire map of your floor plan in either 2D or 3D, and make adjustments like room merging, division and renaming, plus handy stuff like being able to add virtual walls and no-go zones. You can even select the direction of your wooden floors so the bot moves in the direction of the seams for more effective dust collection.

The app also allows you to drive the bot around the home remotely while viewing the scene from the front camera – a handy feature for checking on pets when you're away from home. In the pantheon of robot vacuum apps I'd say it's one of the better ones but still a little way off the wholesale customization possibilities provided by the likes of Roborock.

How I tested the Dreame L40 Ultra

As per usual, I spent two weeks living with the Dream L40 Ultra and noted where possible any anomalies in its cleaning patterns. Thankfully there are none to report. I also performed a number of spot checks by programming it to clean a specific dog rug and a section of hard flooring with an ingrained stain. I also took into consideration its overall performance and whether or not it fitted comfortably within a home environment.

Proscenic Q8 Max: two-minute review

The Proscenic Q8 Max offers a lot for its budget-friendly price. There's mopping functionality built-in, and it comes with an effort-saving self-empty base to save you from having to constantly empty the onboard dust cup. At 4,200Pa, the suction is surprisingly high for a model in this price bracket, too. I put one to the test to see how it compares to the rest of the best robot vacuums on the market, and I was fairly impressed.

In my cleaning tests, I found it did a good job of sucking up everything from fine dust to larger debris on hard floors, and when amped up to maximum suction mode it also performed well on my carpet-like rugs, although I suspect it would struggle with thick carpet. The suction is powerful enough to pull up long hair, but I did find it easily became tangled in both the main roller and the side brush, and both needed regular de-hairing.

The mop function is great for tackling fresh spillages and keeping hard floors looking smart, but it's not powerful enough for dried-on dirt (although to be fair, even premium robot vacuums struggle with this). This feature is best for maintenance rather than deep cleaning.

You select the suction power and water flow for each room according to floor type, and with three options for each, you have decent control over your cleaning. The bot automatically amped up suction when it sensed it was on a rug, but (unfortunately) did not also shut off water at this point, so you'll need to set up no-go zones on the app to avoid damp carpets.

Using smart 360 LiDAR navigation, the Q8 Max creates detailed maps of your home, and it can store information for up to five levels. On test I found it did a decent job of navigating my apartment, and for the most part avoided obstacles, especially after it had done a few runs and got its bearings properly. The navigation isn't perfect, though. The companion app is easy to follow, allowing for easy scheduling, no-go zones, and room-specific cleaning preferences.

Overall, the Proscenic Q8 Max is a solid choice for anyone looking for a decent robot vacuum on a budget – it compares well to TechRadar's best cheap robot vacuum picks. On test, I was generally impressed with how much time it saved me in keeping the apartment clean, even if it didn't get every single nook and cranny spotless. That's the short version – read on for my full Proscenic Q8 Max robot vacuum review.

Proscenic Q8 Max review: price & availability

• List price: US$299
• Launch date: July 2024
• Available: US only

The Proscenic Q8 Max launched in July 2024 and at time of writing is available in the US only. It sits in the budget range for robot vacuums (TechRadar counts anything under $500 as budget for robovacs), and it's a standout option given its features. It can mop as well as vacuuming, and auto-empties dust into its dock – both features that are unusual at this price point.

For that very affordable price, you get a complete package, including a spare side brush, mop pad, and dust bag. When you consider the convenience of self-emptying alongside smart navigation, customizable cleaning options, and a solid performance, I think the Q8 Max is an excellent deal for the price. However, you'll naturally need to make some performance compromises for this price point (I'll get into that in detail in the Performance section).

Proscenic Q8 Max review: design

• Combination vacuum and mop, and does both simultaneously
• Comes with a relatively compact, self-emptying base station
• Various spare parts included

The Proscenic Q8 Max's design is compact and modern. It's slim enough to slide under furniture and features a sleek, all-black look. The robot vacuum is 3.8 inches tall and 12.6 inches in diameter; the charging station is 8.5 by 6.67 by 10.5 inches.

This base station includes a larger dustbin into which the small onboard bin will automatically empty when docked. Unsurprisingly for this price, there's no automatic draining or refilling of the bot's water tank.

I was pleasantly surprised by the minimal plastic that was used to transport the Proscenic Q8 Max. Aside from a few plastic wrappings, most of the unboxing waste was cardboard, something to keep in mind if you value a more sustainable option.

Setup was an absolute breeze; I followed the Quickstart guide and had the robovac up and running in no time. The charging station does double duty, automatically emptying the dustbin into a disposable dust bag (which comes preinstalled). With extras like a spare HEPA filter, side brush, and mop pad included, you won't need to buy replacements right away.

In fact, the only setup annoyance I experienced is that, because it's only compatible with 2.4GHz Wi-Fi, so to be able to connect this device, I had to temporarily change my 5GHz Wi-Fi to 2.4GHz so that the device could connect.

The Proscenic app allows you to map your home, divide rooms, and customize cleaning zones, which was especially useful for my quirky apartment layout. It uses LiDAR for navigation.

There are three suction powers and three water levels, and both need to be manually selected when you start a cleaning session. There is a little automation – for instance, the robot vacuum will increase suction when it detects a rug but won't also turn off mopping on soft floors (I'll get more into this in the Performance section).

Proscenic Q8 Max review: performance

• Solid suction on hard floors; max mode will clear most debris
• Decent navigation and obstacle avoidance, especially after initial setup period
• Mopping fine for light spills, but tough stains need manual intervention

I tested the Proscenic Q8 Max over the course of a few weeks, putting it through its paces in my 21 meter-square, one-bedroom apartment. Let's start with vacuuming performance. There's a maximum suction of 4,200Pa, which is good for this price – I'd expect more like 3,000Pa for a budget model.

There are three suction levels to choose from, and you need to select these manually before setting the robot off on its cleaning task. I threw everything I could at the Q8 Max during testing, from fine dust to hair to larger debris like oats, and tried it on both its lowest and highest suction settings, on hard floors as well as carpet-life rugs.

On the lowest suction mode on hard floor, the robot struggled a bit with finer dust and left some debris scattered. However, it really stepped up on the highest suction power, cleaning up almost everything in sight. Rugs similarly proved a bit of a challenge on the low power mode, but switching to high power yielded much better results.

The side brush was very effective at attacking the debris around the edges of rooms. Of course, the actual robot has to fit into those corners, but as long as it does, the side brush was able to do its job well.

One bigger test for robot vacuums is how well they can deal with hair. I have shoulder-length hair and while I found this robot vacuum picked up strands very well, they did tend to get caught in both the side brush and main brush. For the vacuum to function at its highest potential, I had to regularly clean the brushes to remove the hair.

I appreciated the addition of the self-empty dock, which can hold several weeks' worth of dust, making this a nice, low-effort solution. Many budget robot vacuums just have a simple charge dock, so I appreciated this more advanced option.

One useful feature is that the Proscenic Q8 Max will automatically ramp up suction when it detects that it's moving from a hard floor to soft carpet or a rug. Less impressive is that it won't also switch off mopping when it senses carpet – something I unfortunately discovered after a mopping session that left my rug wet. To prevent this from happening, you can set up no-go zones on the app, which are areas that the Proscenic Q8 Max will not go over during a mopping session.

Rug mishaps aside, I was generally impressed with the Proscenic Q8 Max's mopping powers. It handled everyday spills, like water and even dried milk, very well. However, it didn't manage to clear more stubborn stains – though that's not uncommon for robot vacuums. The water tank and mop pad are easy to install and to clean, and I appreciated the ability to adjust water flow for different floor types via the app.

Some cheaper robovacs require you to manually swap over the backplate when moving from mopping to vacuuming, but that's not the case here: the Proscenic Q8 Max can mop and vacuum simultaneously.

Maintenance was easy too – emptying the dustbin was hands-free for weeks at a time, and cleaning the mop pad and side brush was straightforward. Removing the mopping pads and washing them regularly is key to making sure the moping sessions are leaving your floors as clean as possible. There are models that have docks that can clean your mop pads, but you'll have to pay a lot more for this function (most are at least $1k/£1k. And even then, you'll need to take care of the occasional deep clean of your mop pads.

My testing also included checking how well this robot vacuum navigated my apartment and avoided obstacles like furniture. I found the obstacle avoidance feature worked well after a few sessions, bumping into fewer objects the more I used it. Similarly, there were a couple of sessions where the robot vacuum seemed to be confused and kept going over areas that it already vacuumed/mopped but after a while it settled itself and was pretty consistent.

I also let the robot vacuum map my apartment, and while the initial mapping was slow, the app allowed me to customize and fine-tune the room layouts with ease.

In terms of noise levels, the Proscenic Q8 Max is relatively quiet, especially on its lower settings. During testing, it measured 57.5 decibels in low suction mode, 60.6 decibels on medium, and 66.6 decibels on high. Even at its loudest, it's not overly disruptive, making it a good choice for cleaning while you're home without too much noise pollution.

Proscenic Q8 Max review: app

• Easy-to-use interface with clear instructions
• Option to set cleaning schedules and room-specific preferences
• Requires 2.4GHz Wi-Fi for setup

During my review period, I used the Proscenic companion app extensively, and overall, I found it intuitive and straightforward. Setting up the robot vacuum and mapping out my apartment was quick, although it did require me to manually swap from my 5GHz Wi-Fi connection to a 2.4GHz one for setup. Once connected, I was able to create a map of my apartment, customize cleaning zones, set up no-go zones, and adjust the suction and water flow levels for specific rooms.

One of my favorite features is the ability to schedule cleaning sessions for different rooms or times of the day. You can also track where the robot has cleaned in real time, which is handy if you're out and about. Additionally, voice control via Alexa, Google Home, or Siri is a nice touch for starting a session hands-free. The app makes the Q8 Max feel even more powerful and personalized, allowing me to clean my home exactly the way I want.

The ability to map up to five levels and store them in the cloud makes this vacuum a great option for people with multiple floors. The app allows you to customize cleaning preferences for each level for added convenience.

How I tested the Proscenic Q8 Max

I tested the Proscenic Q8 Max over the course of a few weeks, running it through its paces in my 21 meter-square, one-bedroom apartment. I ran tests to see how it handled both fine dust and larger debris (hello, oats), using both the lowest and highest suction settings. In terms of mopping, I tested it with everything from spilled water to dried milk to see how it would perform on everyday messes and stickier spills.

I let the robot vacuum map my apartment, and checked how well it navigated around obstacles like furniture and rugs. During my review period, I used the app extensively, scheduling cleanings, setting no-go zones, and adjusting suction levels and water flow for different rooms.
