3i G10+ robot vacuum: two-minute review

The 3i G10+ is a hybrid robot vacuum and mop that has a clever USP that makes it an especially good choice for small homes: the onboard dust cup is around twice the usual size, and compresses its contents to fit even more in. It's an ideal solution for those people who don't have space for a massive self-empty base station taking up their living room, but equally don't want to have to manually empty dust after every clean.

While it lacks the fancier features found on today's best robot vacuums, it's certainly one of the best budget robovacs I've tested, punching above its affordable price tag. There are several features I wouldn't expect in this price bracket, including an extending side brush and a mop pad that kicks out to get closer to the edges of rooms and can lift when traversing carpet. The result is very thorough vacuuming, strong edge cleaning, and solid mopping too.

It's not perfect. I found the 3i G10+ struggled to mount the charger when the dock was placed on a carpet, and the object avoidance is a little hit-and-miss. It's also not the best choice if mopping is your priority – the small onboard tank needs refilling regularly, and the fact the mop pads can't be removed from their base for machine-washing is annoying.

However, given the overall balance of performance to price, I think the 3i G10+ is a very solid recommendation. For me, the pros vastly outweigh the cons. Read on for my full 3i G10+ robot vacuum review.

3i G10+ robot vacuum review: price & availability

• List price: $449 (about £560 / AU$1,110)
• Available: US only
• Launched: January 2025 (on sale June 2025)

The 3i G10+ was unveiled at CES 2025 and then went on sale in June that year. It's only available in the US, and any way you slice it, the 3i G10+ is very well-priced for what you're getting. At full list price, it's $449, but at time of writing it was reduced to $399 (about £560 / AU$1,110). Both fall into the TechRadar budget price bracket for robovacs. Sure, you can go cheaper with some robot vacuum models, but to get one with mopping capability, this is about as low as you can go.

There's also the innovative dust compression, enabling you to avoid having to make space for a bulky dock. There are only a few other bots that offer this. One example is the Narwal Freo X Plus, which costs about the same as the G10+ (going for $399.99 / AU$899), but has some unwelcome quirks that the 3i doesn't suffer from. There's also the Roomba 205 DustCompactor Combo for $469.99 / £399, but the least said about that bot and its performance, the better.

The Shark Matrix Plus 2-in-1 goes for the same price when discounted, but has a higher MSRP of $699.99 / £449.99. It does have a bigger auto-self emptying base station with a 1.9 quart (about 1.8L) dustbin capacity, so requires a bit more space. It's also a bit older of a model, which at the time of review had a glitchy app and just average mopping. With the 3i G10+, you get 1 still very good 1L dustbin without having to set aside the space for such a big base station. And that's Shark's most reasonably priced mopping robot vacuum.

The Ecovacs Deebot N10 Plus might be the robot vacuum that the 3i G10+ reminds me of most. The Ecovacs has a higher MSRP of $649.99 / £499 / AU$999, but can be regularly found at the same price as the 3i G10+. It also has a small auto-self emptying base station. It, however, has an annoying quirk in that you have to physically remove the mop pad for use on carpet. And in that regard, the 3i G10+ is easier to use, as I'll get into below.

While the 3i G10+ isn't quite perfect, it sets a high bar for anything around $400.

3i G10+ robot vacuum review: design

• Large capacity onboard dustbin with compression
• Water tank is small but easy to access
• Extendable side brush and mop pad

The 3i G10+ might have the typical disc shape, but it doesn't look like most robot vacuums. Instead of the little raised navigation tower poking out of the top, this robot vacuum has a much larger, almost egg-shaped raised portion that not only contains sensors (the typical reason for these raised areas), but also the power button and, most importantly, the dustbin.

That dustbin is unusual in that not only does it have a supersized 1L capacity – most robot vacuums have less than half of that – but also an internal mechanism to compress all the dirt and debris coming in. That means that even though there's no auto-empty dustbin in the dock (instead, it's a compact, charge-only setup), you won't need to empty the onboard bin too regularly. Because the dust is potentially sitting around in the bot for a while, 3i has built in a UV light to keep things hygienic.

Getting back to the exterior of the 3i G10+. The water tank hugs the back of the unit and pulls off and snaps back into place via magnets, making it very easy to access and fill up. It has a small capacity – just 247ml – so it needs regular refilling.

(If you're using the mop on a regular basis then a bigger, more comprehensive clean station that can wash and dry the mop pads for you, as well as refilling the tanks, is a big effort-saver. Although you will of course have to make space for it.)

Underneath, there's a single side brush, a brush roll, and a stationary mop pad. However, there's more going on here as well. That side brush can extend out to reach further into the edges of rooms. The mop pad is just a stationary one, but the 3i G10+ can move the whole pad out a bit for more thorough edge mopping too. Those kinds of features are unusual for robot vacuums at this price point.

• Design score: 4.5 out of 5

3i G10+ robot vacuum review: performance

• Very good vacuuming and solid mopping, including edges
• Mop pad can't be removed from mount for machine-washing
• Quiet operation

While I usually prefer robot vacuums to have two side brushes, one on each side, the single brush and brush roll on the 3i G10+ proved more than up to the job of vacuuming whatever dirt, dust, and debris was lying around. It helps that the side brush actually extends out, sweeping anything away from the edge of the room and into the bot's suction path.

I used this robot vacuum on hardwood flooring, tile and carpet, and found it did a very solid job on all three. I also ran TechRadar's usual suction tests, sprinkling flour, sugar, and breakfast cereal on the floor and seeing how efficiently it cleared it. It took two passes to get everything, but once those were complete, you couldn't tell that anything had been spilled.

The mopping performance is pretty good as well, though not quite up to the standard of the vacuuming. The mop pad is the flat kind that gets dragged across the floor. It's great for surface-level cleaning but not tough enough for anything more challenging – I find dual, spinning mop pads offer more thorough clean.

In general use I found the coverage was good, and not streaky the way that this kind of mop pad can be. Because the mop pad can kick out to the side, the si G10+ is great at mopping into the edges of rooms. Also a plus is the fact that it will lift the mop pad up a few millimeters when going onto carpet to keep said carpet from getting wet – you don't always get that kind of functionality with a bot at this price point.

I ran some mopping tests that involved spilling soda and coffee on the floor and seeing how well the bot handled it. While it cleared the area effectively, my whole floor ended up smelling like coffee and soda afterwards. I'd recommend tackling spillages manually, to avoid this.

Because the base station doesn't have mop-cleaning capabilities, you'll also need to stay on top of washing the mop pads fairly regularly. Annoyingly (and unusually), while the mop and its mount can be removed from the bot, the cloth part doesn't come off its mount. That means you can't throw it in a washing machine, but instead have to hand-wash. I was annoyed to find the mop cloth-and-mount took nearly a day to dry, though it went a lot quicker when I put it in the sun.

The object avoidance is unfortunately not as good as advertised. While the G10+ did manage to register and avoid some objects, I also watched it push around a bag clip, bump into a dog water bowl, and climb up on the base of a chair and end up stuck. Overall, the object avoidance is rather hit and miss. I've found that to be par for the course with more budget and mid-range models, though.

On the bright side, operation is relatively quiet, registering at 52dB during regular use and 56dB when extending side brush. I've used some robot vacuums that get much, much louder and it can be distracting. Having one with a quiet drone, especially when I'm trying to work or do something when it's running, is appreciated.

The battery lasts a very decent 240 minutes – enough time to clean the full 700 square feet area it could reach without having to recharge.

Lastly, though it vacuums just fine on carpet, it can't seem to get back onto its base station when on carpet (medium pile for reference). It's as if the 3i G10+ can't catch onto the ramp attached to the base station to reach the charging contacts. It's a bit strange and one of the drawbacks of not having a bigger mat for the robot vacuum to go up on.

• Performance score: 4 out of 5

3i G10+ robot vacuum review: app

• Straightforward to set up and use including maps
• Has an AI Auto Mode to make things even easier
• Comes with pet camera and manual controls

I typically don't find a lot of issues with robot vacuum apps these days, and it's no different with the 3i app. It's intuitive to get started, from pairing to going through the various instructions to complete the setup process. Other than waiting for the app and vacuum to pair and connect to WiFi, it's also a straightforward process.

Part of setting it up is also mapping your space and, though the 3i G10+ takes its time, it does a thorough job and even guesses the names of different rooms (not always correctly). Editing the map does take a tiny bit of menu diving, but once you get the screen to make changes, it works well and is happy to let you partition certain spaces more than once – an issue I've actually had with some models.

As far as using the app, the 3i G10+ home page is straightforward with the map top center, important info at the top, menu diving icons top right, as well as the more specific cleaning functions on the lower half of the screen.

There's a lot of flexibility for adjusting how you want your space cleaned including whether you want to vacuum or vacuum and mop, along with suction power, water level, cycles, and more. But if you don't want to manually set the cleaning mode, 'AI Auto' will decide the various settings for you. I found it useful for spaces with different types of surfaces – for example, it'll adjust automatically when going from hardwood to carpet.

Beyond the meat and potatoes of the app, there are more useful features including Alexa and Google Voice Assistant support. You can even take over the camera and motor functions to check on a pet when you're not home.

3i G10+ robot vacuum review: alternatives to consider

How I tested the 3i G10+ robot vacuum

To test the 3i G10+, I used it for a couple weeks, testing its vacuum and mop capabilities not only on hardwood floors, but also when going from hardwood floors to carpets (with some intentionally dropped objects here and there). I also tested its cleaning abilities with spillages of various types. I went through every nook and cranny of the app, looking at things like mapping and ease of use.

iRobot Roomba 205 DustCompactor Combo: two-minute review

The Roomba 205 DustCompactor Combo feels like a missed opportunity given iRobot's recent restructuring and slew of new upgraded floor bots. The unique dust compactor is an intriguing concept – the bot houses an oversized internal dustbin with a motorized paddle that compresses all debris, theoretically negating the need for a large self-emptying dustbin dock. However, in practice it's messy to deal with and ultimately impractical, especially if you have shedding pets in the home.

Granted, the 205's suction performance is acceptable enough – although not up there with what you'd get with one of the best robot vacuum on the market – its halfhearted mopping system is extremely outdated and when the mop pad is fitted, it prevents the robot from traversing rugs or carpet. The 205 is also a much noisier machine than any other robot vacuum cleaner I've thus far reviewed. And while its newly-adopted LiDAR navigation is clearly better than the company's previous V-SLAM camera-based incarnations, it also feels erratic and unsophisticated, at least when compared to other LiDAR systems.

I used to be a massive fan of iRobot products but I'm absolutely dumbfounded by how poorly its latest machines have behaved. The Roomba Combo 10 Max was mostly disappointing but I actually think that the Roomba 205 is worse. It's just so frustrating to use and requires too much intervention from the user. I wish I could recommend this model but it just doesn't perform as you'd expect for a robot vacuum cleaner in the year 2025.

Roomba 205 DustCompactor review: price & availability

• List price: $469.99 / £399
• Launch date: March 2025
• Availability: Widely, including US and UK

With a list price of $469.99 in the US and £399 in the UK, the iRobot Roomba 205 DustCompactor Combo sits towards the top of the mid-range price bracket. Note that at time of writing, there's a $170 discount in the US.

Given all the peculiarities with this machine, if you don't mind making a little more space for a simple, small-bodied, self-emptying dock in your home, I would recommend doing some research on other models in the same price range. For instance, the Roborock Q5 Pro+ has a list price of $699.99 / £499.99 but can often be picked up for a similar price to the Roomba 205, and offers far more reliable performance.

Alternatively, if a small dock is the priority and you're not dealing with huge amounts of dust, it could be worth considering a model without dust compression. There are a number of cheaper options in this category, for example, the Dreame D9 Max Gen 2, which costs $299.99 / £219 at list price and impressed our reviewer.

If you're hellbent on going for the Roomba 205 DustCompactor Combo simply because of its unique bin system, by all means go ahead. But make sure your home is on the smaller side and with no rugs or carpet to block its path when the mopping pad is attached.

Roomba 205 DustCompactor specs

Roomba 205 DustCompactor review: design

• Hybrid robot vacuum and mop with internal dust compression
• Compact, charge-only dock that refuses to stay put
• Only one rubber roller rather than iRobot's usual double rollers

Given the financial troubles that have besieged US brand iRobot during the past few years, it's good to see that the company has since restructured itself and developed a new range of robot vacs and mops entirely from the ground up. However, in design terms, I feel that the Roomba 205 is a pale shadow of its forebears like the Roomba ‘i' and ‘j' series, and especially the excellent S9+ (for my money, by far and away the best robot the company ever made).

The USP for the Roomba 205 DustCompactor Combo I'm reviewing here is that it's equipped with an extra large onboard dustbin (about 1.5 liters) with an internal motorized plastic paddle that swings back and forth to compact all detritus towards the back of the bin, thereby creating more space for subsequent cleaning sessions. That means it can offer a large dust capacity without the need to make space for a large auto-empty dock.

iRobot states a period of about 60 days before the bin needs emptying but I can see it filling up with dust and hair within a week or so if you have shedding pets in the home (this is not one to consider if you're on the hunt for the best robot vacuum for pet hair). On the plus side, you will never need to buy any extra dust bags.

From an aesthetics point of view, the 205's dock is almost invisible in a room so I can see the appeal of a back-to-basics approach like this. However, from my tests I've found that emptying the bin myself has been quite messy and not especially pleasant (I'll get into this more in the Performance section).

Personally, I'm not sure such an innovation is necessary, either. The are models on the market that have petite, unobtrusive self-empty docks equipped with large dustbin bags – I'd happily sacrifice those few more inches of floorspace for the relative ease of this setup.

Another drawback of iRobot's solution is that the 205's titchy dock is so light in weight that it shifts around when the robot is docking and this often causes the robot's contacts to fail to connect with the dock. It's even worse when the dock is placed on carpet – I tried this the first time I used the 205 and it failed to dock at all; the charging base simply refused to stay put.

Let's take a look at the unit itself. The Roomba 205 is roughly the same width as most robot vacs but a bit taller, which means it might not reach under some low furnishings.

Flip it over and you'll notice that the 205 has only one rubber roller brush, which is a bit strange considering that iRobot invented the twin roller brush that so many high-end robot vacs use these days. I'm not sure why, but this roller brush tends to clatter across my hard wooden floors and jitter over one of my Persian-style rugs as if it were on a corrugated surface, which is distinctly annoying.

iRobot doesn't list any of its robots' suction power in Pascals so it's difficult to tell how powerful it is in comparison to other bots on the market. But, hey, you can take it from iRobot that it's ‘70x the suction of the older 600 series', whatever that means. Incidentally, you get three levels of suction power with this unit – Light, Normal and Deep.

The 205 also comes with the obligatory side spinning brush for flinging wayward debris along edges into the path of its suction. However, unlike many newer (and perhaps pricier) robovacs with side brushes that automatically articulate outwards when traveling along edges and in corners, the 205's side brush is firmly fixed in position.

The 205 DustCompactor's mopping system comprises a simple mop pad with its own 250ml water container above it. The user takes charge of filling the tank and washing the pad – the dock won't help with this, as is the case with some bots.

For mopping, the robot will simply drag the pad along the floor. You can set the amount of water that's dispensed but just don't expect any miracles, especially when it comes to deep stain removal. This kind of basic mopping setup isn't unusual setup for an affordable robovac, and for general day-to-day floor cleaning it does pass some muster.

Me? I've removed it entirely because I've since discovered that the robot refuses to cross rugs or carpet if the mopping pad is attached, but more on that in the Performance chapter.

Given that iRobot has refused for years to include LiDAR as part of its navigation system, even when every other manufacturer and their dogs have, it's refreshing to note that the company has at last seen fit to include LiDAR navigation on the 205.

However, while most bots have their LiDAR turret in a raised puck their top surface, to allow a full 360-degree view, here iRobot has hidden it behind a narrow slot just above the camera, thus restricting the view to around 180 degrees. Thankfully the camera provides backup, although it's not AI enabled like so many models these days.

Setup

The iRobot Roomba 205 DustCompactor Combo arrives in a small box containing the robot, its tiny charging dock, a clip-on side brush and rear mop mount. Initial setup was relatively easy but only once I'd discovered that the old iRobot Home app isn't compatible with this model, so I downloaded the newly upgraded Roomba Home app instead.

All went according to plan until it connected to my Wi-Fi and then proceeded to automatically download the latest firmware update. That's normal, I thought, but then a warning popped up saying that ‘Roomba is having some trouble updating and to make sure Rosie (Rosie?) is docked with a good Wi-Fi connection'.

‘Rosie' was docked and the internet was fine so I waited a while, then got impatient and restarted it. It sprang to life again and gave the impression it was ready to work, so I commanded it to and it proceeded to spin round on its dock for about a minute, entangling itself on its own power cable.

I took it off the dock and placed it on the floor, whereby it started spinning again. At this point I thought I'd been handed a dud so I took it to a different area downstairs, plugged it in and left it to fully charge. Lo and behold, when I launched the app again, it showed the ‘start mapping' screen which suggests it was updating all along, only without any icons or progress bars to tell me so.

Anyway, I tapped the mapping button and it proceeded to map my entire floor plan efficiently and – because the roller brush was turned off – without getting caught on any rugs. The upshot of all this is that if you decide to buy a Roomba 205, just be patient and let it fully charge and complete its first firmware update, even if it says it's having trouble connecting, before trying to request any cleaning.

• Design score: 2 out of 5

iRobot Roomba 205 DustCompactor Combo review: performance

• Decent vacuuming but emptying is messy
• Woeful mopping and won't ride over carpet with mop attached
• Below average obstacle avoidance

After a confusing setup, the 205 started behaving as expected and mapped my open-planned, four-room downstairs area surprisingly quickly, even if it did create nine different rooms that I had to merge in the app. This is common with most robot vacs when mapping open-plan environments though it has to said that nine divisions is a record for me.

Also, for a LiDAR-equipped robot, the detail of its mapping in the app is lamentable and way behind the likes of Roborock, which displays every nook and cranny instead of just a basic overview of one's floor plan.

Since it's been running, the 205's LiDAR-based navigation has been mostly okay though I have had one or two issues where it has either got stuck while trying to cross a loose rug – a common issue with some models – or suddenly stopped dead next to a kitchen cupboard for no apparent reason. With most other robot vacuum I've tested, I've learned their working methods to some degree, but this model's navigation process remains largely a mystery to me.

Obstacle avoidance

As mentioned above, the Roomba 205's LiDAR is tucked under a slotted housing so it doesn't appear to give the robot a full 360–degree view. There is a camera on the front, however, and this seems to help with its obstacle avoidance. In my test I placed the usual assortment of dog toys in front of it, plus the obligatory phone cable. It carefully avoided the first two large toys but simply snow-ploughed all the others. As expected, it also rode over the phone cable and then dragged it along behind it for a while.

In the pantheon of obstacle avoidance, the Roomba 205 isn't the worst I've seen but it's not that great either, and clearly not a machine to have running around if you have (for example) a non-house trained puppy in the home.

Vacuum performance

Let's take a look at the vacuuming performance. There are few niggles to note up top. Firstly, as noted above, the Roomba 205's rubber roller made quite a racket as it trundled across my wooden hard floors. But perhaps worse than that was the monotonous high-pitched sound of the suction motor, which was clearly audible from meters away. I measured the sound waves at an average 78dB from five feet away and at an annoyingly high-pitched frequency of 660Hz.

Aside from the noise issues, the side sweeping brush fell off twice during my tests, despite being firmly connected before setting off.

To get an objective ideal of this bot's suction powers, I ran TechRadar's standard vacuuming tests. This involved sprinkling debris of different sizes – specifically, flour, muesli and rice – on the floor and assessing how efficiently the robot picked it up. Here, the Roomba 205 was pretty decent, though it did leave traces of flour in the cracks.

However, when I later went to the dock to grab a photo of the robot returning after a standard cleaning session, I noticed a small scattering of rice and muesli that it had deposited in front of the dock from its previous cleaning test, which suggests it never fully sucked all the rice and muesli into its bin and instead simply held some of it in its brush housing. This anomaly hasn't repeated itself on subsequent tests, so hopefully it was just a glitch.

I then proceeded to run the same tests on carpet. This proved to be quite a challenge, because although the app has a menu item called ‘furniture and zones' under the heading ‘routines', nothing happens when you tap it. What it should do is provide an editable square that can be expanded or contracted over a specific cleaning area.

In the end I opted to select ‘spot clean' which was equally tricky because the map for each room is very basic and cannot be expanded so it takes trial and error to find the exact spot that relates to a specific area. Anyway, I'm pleased – indeed surprised – to report that the 205 collected all evidence of rice and muesli though, like other robots I've tested using this method, it did leave some flour marks behind.

Dust compactor performance

Moving on to the unusual bin system. While the Compactor's paddle does indeed push all detritus to the outer edges of the bin, I found that emptying it has been quite messy and not especially pleasant.

Firstly, the lid of the robot's bin doesn't open anywhere near wide enough, so I couldn't find a practical solution for emptying its dusty and hairy contents into my average-sized Brabantia kitchen bin without some of the contents spilling all over the floor. Worse, my model has a sticky bin latch so I've had to be doubly careful when trying to open the bin lest its contents end up all over the floor and my clothing.

iRobot states ‘up to 60 days' of cleaning before the dustbin requires emptying but my test model required emptying after just eight days of vacuuming. I should add that I have two Labradors and two cats that regularly shed hair and my home is also surrounded by woodland and farm fields so it's dustier than most urban environments.

Mopping performance

Onto the mopping. First things first: if you have any rugs or carpet dividing your hard floors, this may be the last hybrid robot you want, because it will not traverse any rug or carpet when the mopping pad is fitted. I first thought that it was the small protruding lip at the bottom of the mop mount that was catching on my rugs but it transpires that the unit has a carpet sensor on board that, in my case, refused to allow the robot to proceed the moment the front half of the robot touched the rug.

It did do its darnedest to head over the rug en route to the hard floor kitchen, but after 10 minutes of trying at every conceivable angle, it eventually announced that it was unable to continue cleaning before returning to the dock, having not performed the assigned mopping task. I can't believe that I'm the only household in the world with rugs scattered over hard flooring but what I do know is that, for me, this model has proved to be as useless as a chocolate teapot when it comes to complete household cleaning without any human interjection.

Anyway, having failed to ride over my rugs, I resorted to carrying the bot to the kitchen so it could perform a spot clean on a spill of milk. I had to make several attempts at this because, as I had discovered for the carpet vacuuming test, the app's map is so unrefined that it's almost impossible to select a specific cleaning spot. Anyway, I eventually spilled some milk in its path and it duly soaked up the milk leaving no signs of it. But then I expected that – much like I'd expect a single swipe with a paper towel to do the same thing.

In its favor, it did also mop the rest of the area quite effectively, leaving only a damp swathe that dried up quickly. I then had to pick the robot up again and place it near its dock so it could get back to charging.

It's not unusual for a budget robot vacuum to have this kind of simple mopping setup (not including the refusal to pass over carpet – that is very unusual). More advanced bots will have pads that vibrate, rotate or press down to dislodge dirt, but you might need to pay a little more for this kind of setup.

iRobot Roomba 205 DustCompactor Combo review: app

• New app for this current range of Roombas
• Very basic with incomplete menus and unrefined maps
• Frustrating and slow to use

The new iRobot Home app was recently launched as a replacement for the older app that's now been renamed iRobot (Classic). Having used it extensively during the past week I can report that there's a lot of work to be done on making this app more user-friendly. Firstly, it's slow to send commands to the Roomba 205 and some user inputs cause a spinning cog wheel to pop up on screen while it sends its signal.

Perhaps I'm too used to Roborock's fully comprehensive app but I found the iRobot Home app to be too simplistic and, at times, very irritating to use. For instance, the floor plan maps it creates are so basic it's difficult to tell where one room ends and another begins. Also, its Spot Clean function is almost impossible to use since you can't expand the map in this menu and the little spot cleaning square it provides can't be placed exactly where you need it.

Although the app allows you to create routines and standard cleaning schedules, and make adjustments to both vacuum power and water amount for mopping, you can't create any specific cleaning zones, like in front of the dog bed or a specific rug. Bizarrely, there is an option to select ‘Furniture and Zones' but when you click on this function, nothing at all happens. I'm sure iRobot will be adding improvements to this app going forward but, as it stands, it's woefully inadequate.

How I tested the iRobot Roomba 205 DustCompactor Combo

As is the way with all TechRadar tests, we live with the product for as long as possible, observing its day-to-day functions and generally appraising it from afar. We then get down to some serious testing while making copious notes on the product's performance.

In the case of the iRobot Roomba 205 DustCompactor Combo, I had it installed at home for just over a week while I observed its navigation behaviour. I then proceeded with my vacuum, mopping tests on both hard floor and carpet using a variety of household ingredients in order to replicate a real-world scenario. I then tested its obstacle avoidance system using some dog toys and the obligatory phone cable.

I should add that this particular review took me a lot longer to complete than usual because the machine in question failed to behave as I expected. Hence, I had to spend extra time repeating tests to make sure its previous hiccups weren't just one-off glitches.

Dreame X50 Ultra Complete: two-minute review

Dreame’s latest robot vacuum, the X50 Ultra Complete, sets a new standard for the best robot vacuums, offering a litany of genuinely useful features and excellent cleaning results. It’s low-maintenance, thorough and features all of the bolts and whistles you’d expect from a premium robot vacuum.

While its 2.4in / 6cm threshold-hopping legs have been the main talking point, it's this robot's cleaning performance that prompted me to award it such a high score. It's highly capable at both mopping and vacuuming, though its battery life does leave something to be desired. Plus, its DToF sensor tower can quickly sink into the main body of the vacuum when it needs to clean beneath low-threshold furnishings.

From its extending side brush and mop pads to its excellent mapping, the Dreame X50 Ultra Complete makes full use of its arsenal of cleaning tools, rounded out by efficient 20,000Pa suction. This powerful robovac only really struggles when faced with fine powders on high-pile or tightly bound low-pile carpets; a fairly common issue for vacuums of all shapes and sizes.

When it comes to object detection and avoidance, the X50 Ultra performed fairly well, although it missed crumpled up paper and shorter wires on occasion. It also failed to spot (fake) pet poop during one test – turning on Pet mode helped improve matters.

If you can stretch your budget to buy the X50, you won’t be disappointed in its value proposition. It’s fantastically low-maintenance, the app is easy to use and the results speak for themselves. That's the short version; read on for my full Dreame X50 Ultra Complete review.

Dreame X50 Ultra Complete: price & availability

• Announced January 2025, on sale from spring 2025
• List price: $1,699.99 / £1,299 / AU$2,999

At its $1,699.99 / £1,299.00 / AU$2,999.00 list price, the Dreame X50 Ultra Complete is one of the most expensive robot vacuums you can buy today. It's available to buy directly from Dreame, as well as via third-party retailers such as Amazon.

Thankfully, Dreame isn’t afraid of a good deal, and in the months since its release I've seen the price drop by $340 / £150 / AU$200. At its list price, it’s toeing the line of being overpriced, but its early deals make for a strong value proposition. It's fairly common for flagship bots to cost well into the four figures these days, and the features here are in line with (or exceed) what you'd get elsewhere for a similar price.

Plus, Dreame is generous with accessories. Out of the box, you not only get the vacuum and base (which are pre-loaded with a dust bag, filters, a side brush and brush rolls), but you also get a full bottle of Dreame’s Multi-surface floor cleaner, two pre-loaded mop pads and ten replacement pads, two spare side brushes, two spare roller brushes, three spare filters and a cleaning brush for the water tanks, making for low maintenance costs in the first year or so.

Dreame X50 Ultra Complete specs

Dreame X50 Ultra Complete: design

• Robot's navigation puck can retract to enter low spaces
• Underneath are tiny legs to hoist the bot over tall thresholds
• Comprehensive dock with heated mop cleaning and UV light treatment

Looks-wise, the Dreame X50 Ultra Complete doesn’t break any conventions. Both the vacuum and its dock are fairly neutral, clad in either white or black with gold or gunmetal accents.

The base is slim at 13.4 x 10.2 x 23.2 in / 34 x 26 x 59cm – although you'll need to add space for the ramp and maneuvering room for the robot to dock. Lift up its lid and you’ll find both the fresh and waste water tanks, while the dust bag and detergent tank are behind the accent panel on the front of the base. It’s also compatible with the Dreame Water Hookup Kit if you wanted a fully automated water refill and drainage system, which is a nice added benefit; I didn’t test this for my review, but broadly speaking, these hookup systems are fairly reliable.

Behind the scenes, there’s a lot more going on in the base; it's self-emptying and refilling, but also packs cleaning tech for both the dust bin and mop pads, offering heated water mop wetting and hot air drying as well as UV light treatment for bacteria removal.

The robot itself similarly manages to pack ample features and functionality into its relatively compact body. It benefits from the direct time of flight (DToF) sensors situated within the sensor tower for accurate navigation and mapping. This can sink into the robovac in order to reach beneath low-clearance furniture, where it relies on its front-facing camera for navigation and obstacle detection instead. You can remove the lid of the robot vacuum to access the dust bin and set up QR code.

The underside is where the action happens. Here is where you’ll find its array of cleaning tools. Let’s get the bad news out of the way; while the extending side-arm is fantastic for edge cleaning, my robovac nemesis as a long-haired person are bristled side-arms. Hair is easily tangled, but I’ve yet to test a robovac where I don’t face this problem. Thankfully, the dual brush rollers (Dreame calls these the Hypersteam Detangling Duobrush) are super effective, making light work of pet and human hair alike.

You’ll also find the Dreame X50 Ultra Complete’s golden goose amidst the cleaning tools: two stumpy 'legs' that allow the vacuum to safely propel itself over small thresholds and furniture legs.

Dreame X50 Ultra: performance

• Thorough vacuuming, superb mopping, and excellent edge cleaning
• Threshold clearing is impressive, but descents are alarmingly noisy
• Pop-down puck consistently identified low thresholds

After a painless five-minute setup and quick mapping, the Dreame X50 Ultra is a dream-e come true, passing almost all of my standard robovac tests with flying colors.

Let's start with the special features. The tiny legs could be a game-changer for anyone with tall thresholds. The vacuum will square up against the surface and extend its legs to vault itself up and on to the surface. This part is a little slow, but overall works extremely well. You can see it in action below (filmed at a press event, where I could capture a clearer view of the mechanism in action).

Moving downhill is a little less graceful, and involves charging off the ledge and landing with an alarming crash.

The pop-down puck also worked well on test. I found it consistently identified low-threshold obstacles and receded into the vacuum. The inaccessible area beneath my sofa has never been cleaner.

Cleaning tests

Now on to the general cleaning performance. For this, I ran a range of vacuuming and mopping tests on different floor types.

On hard floors, the X50 Ultra Complete was easily able to collect a majority of the large, small and powder debris on its first pass of the area. While its side brush did send some debris flying, the vacuum returned for second and third rounds of cleaning to collect any mess it had missed the first time around. The story was much the same on my low and high-pile carpets, though as I’d expect, there was some residue left behind from the powder and fine debris.

When it comes to mopping, I was most impressed with the X50 Ultra, offering the most thorough mopping I’ve experienced so far, with ample controls in-app to customize your clean. I put the X50 Ultra to the test with sticky spills, wet spills and dried-on stains, and it cleaned each with ease, though did leave some small streaks. You can either mix in the Dreame-approved detergent directly to the water tank or use the built-in automated detergent tank; I found both worked well.

Edge cleaning is similarly impressive, thanks to the extending side-arm and mop pads, which paired with the X50 Ultra Complete’s excellent mapping to offer the most rigorous edge clean I’ve personally experienced.

The X50 Ultra Complete successfully identified all of the flooring types in my apartment, automatically adjusting the level of suction and mopping based on floor type and dirt levels. It features the increasingly popular mop-pad-lifting tech that keeps your carpets from getting soggy.

Broadly speaking, its obstacle detection is solid, though there were some exceptions; you’ll want to make sure small obstacles like shorter wires, crumpled paper and socks are cleared before setting of the X50 Ultra Complete.

Poop detection, however, has a quirk. Before I turned on Pet mode, the X50 Ultra Complete repeatedly failed to spot and avoid my mock pet poop. Instead, it barreled headfirst into the fake feces multiple times, especially when navigating between rooms, in low-light or on dark backdrops. However, its dodge rate improved significantly with Pet mode turned on. The X50 was able to avoid my fake pet poop 95% of the time with this mode on. (This is one of the settings we recommend you adjust when using any robot vacuum.)

Similarly, floor type and dirt detection worked really well for me, and while I’ve seen some reviewers found it didn’t always clock carpet, I didn’t face that issue in my testing. As a result, I also found the lift-off mop pads worked well and kept my carpets nice and dry.

When it’s done with clean-up, the Dreame X50 Ultra Complete returns to its base for self-cleaning and drying, which I was really impressed with. It not only washes the pads with hot water, but also dries them, and uses dual UV lamp bacteria removal technology to keep both the mop pads and the dust bag fresh and clean. Overall, it’s pretty low-maintenance, benefiting further from its effective dual-roller Hypersteam Detangling Duobrush requiring little-to-no hair removal. The side brush, however, is prone to clumps of tangled hair.

One of its only other failings is the battery life; Dreame quotes a 200 minute runtime on quiet mode and a 4.5-hour recharge. When tested in my home, I got an average of 90 minutes use out of the vacuum, which is certainly lower than I’d hope for such a pricey device. I’d assume that’s down to some of the more intelligent features, given the Dreame X40 Ultra features the same 6400 mAh battery but fared better in our testing.

How I tested the Dreame X50 Ultra Complete

I used the Dreame X50 Ultra for two months as my primary robot vacuum, completing regular cleaning cycles in addition to my deeper testing. To test pickup performance, I used everything from fine powder (cornflour) to oats and grains to see how well the vacuum clears up debris both in the middle and at the edges of rooms. To test mopping performance, I made wet, sticky and dry spills for the device to clean up, and I also left various obstacles around my flat to test navigation and object detection.I’ve been testing robot vacuums for three years, and in that time I’ve tried everything from cheaper models to premium devices like the Dreame X50 Ultra, which means I’ve got a solid understanding of what makes a robot vacuum worth the money.

Here's more on how we test robot vacuums

Roborock Qrevo Edge: Two-minute review

Roborock has been making excellent robot vacuums for a while now, with the Qrevo series stepping it up over the Q and S series bots. With more suction power and a wider feature set compared to older models, the Roborock Qrevo Slim and Roborock Qrevo Curv performed really well in our tests. The Roborock Qrevo Edge joined its siblings in January 2025 and is quite effective at autonomous cleaning… provided you use it for the daily (or regular) cleaning tasks.

It’s essentially the love child of the Curv and the Slim: it uses the exact same technology as the former with an identical bot, but inherits the self-cleaning dock design from the latter. So instead of a curvy dock, it’s a more traditional design that’s simple to set up and use.

It’s a nice-looking dock, but I question its lack of proper sealing. The lid of the dirty-water tank in the unit sent to me for this review had tiny gaps even after being clipped closed and I found that if I didn't clean it out soon after a mopping run, it would begin to smell.

It’s similar with the dust bag too, wherein I found that it can emit a slight odor when the bin in the bot is being cleaned out automatically. That means you might have to replace the dust bag sooner than necessary which, in turn, will increase the ongoing costs of running the Qrevo Edge.

There’s not a lot to complain about when it comes to the robot vacuum’s cleaning prowess as long as it’s not expected to handle tough spills. There’s 18,500Pa of suction power, which I found to be good enough to clean up a carpet with hair or fur tangled in the fibers, although a few strands always get left behind as robot vacuums are meant as ongoing maintenance cleaners rather than being the primary cleaning appliance.

It’s also quite good at picking up fine powders and slightly larger debris like oats, but it regularly misses room edges. That’s not unique to the Qrevo Edge but, given its name, I was expecting slightly better edge-cleaning performance.

Mopping, too, is also good when it comes to day-to-day cleaning on hard floors and I found it was excellent at sensing the change in floor type to raise its mop pads when necessary. However, despite the extending mop pads, it often missed about an inch along the edges of a room during my testing, and it can spread tough wet spills (like ketchup or milk) across a floor if you aren’t careful with setting up the correct cleaning routine.

Roborock claims that the Qrevo Edge can handle thresholds of up to 4cm, which is true, but it's worth noting that it takes time to cross over, trying to determine the best angle for it and the amount of power it needs to push itself over.

While it excels at being an effective autonomous cleaner for the daily or regular cleaning tasks – and its SmartPlan feature is a game changer in those circumstances – its inability to tackle tough spills when doing a zone clean and get to room edges consistently makes it hard to recommend at its premium price point.

Roborock Qrevo Edge review: price & availability

• List price: $1,599.99 / AU$2,799 (“coming soon” to the UK)
• Launched: January 2025
• Available: In select markets, with wider availability later in the year

The Qrevo Edge was released a few days before the Roborock Saros 10 series was announced at CES 2025 in January. In fact, the Edge is now part of a duo, with the Qrevo EdgeC joining it in March at a lower price point and with some missing features.

The Roborock Qrevo Edge will set you back $1,599.99 / AU$2,799 in the US and Australia at full price, but it’s already discounted down to $1,299.99 / AU$2,499 when purchased directly from the Roborock online store. Some authorized retailers are also offering the same or a better discount in most markets where it’s already available.

UK pricing and availability is yet to be confirmed, but it’s definitely being added to the Roborock catalogue as it’s listed as “coming soon” on the British website.

Despite the discount, the Qrevo Edge is still an expensive robot vacuum cleaner. That’s exacerbated when you consider that the more powerful Roborock Saros 10 (22,000 Pa suction compared to 18,500 Pa in the Edge) is the same price in the US and AU$200 more in Australia. It costs £1,499.99 in the UK. In fact, the Saros 10 has a retractable LiDAR puck that allows it to go under furniture to clean, potentially making it a better investment.

You will need to consider ongoing costs as well. The dust bag will be the most frequent purchase you make but, at some point, you will need to replace the mop pads too due to wear and tear. These aren’t too expensive as you won’t need to replace them too often (the dust bag has a 2.7L capacity that could last you 2-3 months, depending on use), but if you take into consideration the Roborock detergent for mopping, that will quickly add up.

If you’re after good value, something like the Ecovacs Deebot T30 Omni (or the T30 Pro Omni) would be ideal. It cleans just as well as the Qrevo Edge, if not better, although it lacks some of the features you’ll find on the Roborock. Still, the bang for buck you get from similar models to the Deebot is a lot more.

Roborock Qrevo Edge review: specs

Roborock Qrevo Edge review: design

• Sleek, modern dock
• Easy to set up, but may require frequent cleaning
• Extending side mop and brush, anti-tangle split main roller

The Roborock Qrevo Edge’s design isn’t particularly standout – it’s nothing we haven’t seen before – however, its white body (dock and robot) makes it look sleeker than its actual footprint would suggest.

The robot is of a similar size to other models, and the dock’s tray – where it sits to get cleaned and recharge – barely extends out beyond its radius, giving the impression of not taking up too much space.

It’s quite a tall dock though, so you may not be able to tuck it under a countertop or kitchen island, like you can with the Ecovacs Deebot T30 Omni, and you’ll need a good amount of clearance to lift the two tanks out of the dock. So it’s going to need a little open space around it.

Robot design

The bot in particular will be very familiar to anyone who’s ever seen a robovac before, let alone used one. The most obvious feature on the circular robot is the puck-like LiDAR housing on the top. The puck has the Roborock logo in a silver-grey color that adds a touch of class.

Also on top is a magnetic cover to keep the 325ml onboard dustbin out of sight, with cutouts for the LiDAR puck and two buttons. You won’t need to access the dustbin much – only to clean the filter every once in a while or if the self-empty function fails. Even the buttons need to be used sparingly.

On the front there's a camera and additional navigation elements. You can use the camera to run security checks while you’re away or look in on your pets remotely. There’s also a light on the front that comes on automatically if the robot is cleaning in a dark area or room.

A semicircular bumper protects the front, and it’s got just enough give to absorb bumps into furniture and larger obstacles.

The undercarriage has a lot going on. Two large wheels catch your attention first and these help the Qrevo Edge traverse thresholds of up to 4cm high. Roborock calls this AdaptiLift, which has been inherited from the Curv and found its way into the newer Saros 10 as well. There’s also a smaller wheel towards the front of the robot for better maneuverability.

The main roller brush is quite unlike any other I’ve seen before. Instead of being a single bar, it’s made up of two pieces and split in the middle. Both halves have bristles and fins and, to avoid getting hair and fur tangled in said bristles, Roborock says the split design helps strands get pushed to the middle from where they’re sucked into the bin.

There’s also a spinning side brush and, again, it’s designed differently to what’s commonly seen on other brands. The brush has only two sets of long bristles (compared to the usual three), both curved to avoid hair entanglements and push dirt and debris towards the main roller.

The arm that the brush is affixed to can extend outward to give the bristles a longer reach. Roborock calls this FlexiArm technology and it’s also used to extend the mop pads as well.

Again, it’s a familiar design for the mops – two circular pads attached to the plates via some seriously strong Velcro. During my testing I found that the pads extend out individually, never both at the same time as I’ve seen on other brands, and both can be raised 10mm to avoid medium and high-pile carpets from getting wet.

Unlike other premium models like the Dreame X40 Ultra, the mops don’t detach if you want a vacuum-only run.

There is, of course, a small water reservoir tucked away somewhere inside the robot, but the design is such that you can’t see it at all. It gets filled automatically from the clean-water tank in the dock every time the bot needs to do a mopping session.

Dock design

Like many other premium all-in-one robot vacuums, the Qrevo Edge’s self-cleaning dock is a do-it-all pit stop.

It houses two water tanks inside, both of which can be pulled up from the top. They’re marked by different silver drops on a corner of their lids to differentiate them – one for clean water, the other collects dirty mop water.

Both look identical at first glance, but closer inspection reveals a small difference in shape, which allows the clean-water tank to have a larger capacity of 4L compared to 3.5L of dirty water. That’s quite a bit and should allow for two mopping runs of an average two-bedroom home, if not more.

If there's any issue with the tanks – whether the clean water needs refilling or one of them hasn't been placed back correctly – the indicator light on front of the dock turns red. You will occasionally get a voice prompt, plus there'll be a notification on the app.

The tanks close via a hinged lid that clips into place, but the seal isn’t as good as I’ve seen in other all-in-one robovac models. This allowed a bit of nasty odor to escape when I forgot to clean out the dirty water after one cleaning session, meaning you might want to ensure the left-hand tank is washed out as soon as possible.

Below the water tanks is a covered nook for the dust bag. The cover comes off very easily and replacing the bag is also just as easy.

As with other all-in-ones, the base tray that the robot sits on has ridged sides, which allows the mop pads to be scrubbed when they’re being washed. Not only can the dock refill the bot’s onboard water reservoir, empty the bin, wash the mop pads with hot water (167ºF / 75ºC), then dry them with warm air (113ºF / 45ºC), but it can also self-clean that tray.

Overall build quality isn’t too bad, but the lids on the water tanks not closing properly takes away from the premium-ness of the whole design. Moreover, the plastic dock – a material that's not uncommon – just doesn’t quite exude oomph despite the silver details. It’s not that it looks cheap, it just doesn’t look… well, premium.

• Design score: 4 out of 5

Roborock Qrevo Edge review: performance

• Excellent vacuuming on higher settings; can handle tangled hair in carpet fibers
• Mopping also very good on higher settings, but regularly misses edges
• SmartPlan is efficient in terms of navigation and battery life, but the automated cleaning may not suffice

If there’s one thing Roborock does well, it’s providing an easy setup for its robot vacuums. My colleagues have said previously that they’ve not faced any setup issues with other models from the brand and it was the same here. In fact, you don’t even need the manual to get you started, it’s all quite intuitive.

As soon as the robovac was connected to my Wi-Fi network, I checked how much battery it had and immediately sent it off on its initial mapping run. This took just six minutes to complete in a test space measuring approximately 40sqm and containing a carpeted bedroom and tiles in the rest of the apartment.

The initial map was quite accurate in the layout of the test space, and I was then able to edit the rooms: adding furniture and dividing open-plan spaces into their correct room names.

The test space was single-storey, so I wasn’t able to see how well the cliff sensors function. It also had no pets, so I can’t comment on how well the Qrevo Edge’s pet avoidance features work, but I conducted all the other standard TechRadar tests to see how it held up.

Vacuuming

The Qrevo Edge’s 18,500 Pa suction power shows itself off quite well when it comes to its vacuuming prowess. I found it very hard to fault it, even when on lower suction settings – albeit on hard floors that aren’t too dirty. The higher suction options are very effective on carpets, even those with entangled hair within the fibers.

As with other Qrevo machines, there are five power levels to choose from: Quiet, Balanced, Turbo, Max and Max+. Importantly, the app allows you to choose from just a single vacuum-only run or two, meaning it can take on some tough jobs.

As good as the Qrevo Edge is at vacuuming, I do have to note that you shouldn’t expect perfection. I found that hair on carpets are mostly sucked up – say about 98% of the strands – but some will remain. This is more so if you happen to have hair, fur or dirt along the edges of a carpeted room as the side brush just doesn’t have the force to gather these up and pull them towards the central roller.

The proof is usually in the pudding and when I looked at how much dirt the Qrevo Edge collected after its first vacuum-only run (done at the Max+ setting) in a single carpeted room, I was impressed that its higher suction did a far superior job than the 11,000 Pa Ecovacs Deebot T30 Omni that it replaced in my home.

Even the Turbo and Max modes do a good job on carpets, provided you don’t have pets shedding on them copiously – they’re effective for the usual dust-sucking chores. And I had no issues with tangled hair on the main roller brush.

To test how well the Qrevo Edge can handle other kinds of dirt and debris, I conducted TechRadar’s standard tests by sprinkling some oats, tea dust (from a teabag) and tea leaves onto a mid-pile carpet.

I first set the Qrevo Edge to do just a Zone clean for the carpet only, which defaults to the SmartPlan setting wherein the bot chooses its own suction mode depending on floor type. As you can see from the video clip below, it does a pretty good job, although its navigation in this mode is a little erratic.

While all the oats and tea leaves were cleaned up, I could see some tea dust still on the carpet. As a comparison, I sprinkled a little more dust from a teabag and used my Dyson V15s Detect Submarine in Auto mode to clean it up and saw similar results. I repeated the tea dust test with the Qrevo Edge on the carpet in Max+ mode and found no reason to complain.

It’s a different story on hard floors though. For the exact same test performed on tiles, I found that the side brush scattered the larger debris (oats) when doing a Zone clean on the default SmartPlan settings. The scattering happens on all other settings, but when changed to doing a 2x vacuum at Max, it did a better job.

Where it fails quite badly is edge cleaning. I expected most of the tea dust I had scattered along a room edge on a hard floor to be picked up, but sadly that wasn’t the case. Even running it on a 2x vacuum-only run at Max+ made no difference. I had to use the crevice tool on my Dyson to clean up the tea dust remaining on the floor.

Moreover, if you have gaps between tiles or wood panels on your floor, fine dust will invariably get moved into the grouting or the gaps and even the Max+ setting does nothing to clean that up. Larger debris getting caught in those spots, though, will get cleaned, provided you use the maximum suction setting.

To be fair to the Qrevo Edge, though, robot vacuums weren’t designed to be your primary cleaner, but rather for ongoing day-to-day or regular cleans. You'll still want to have one of the best vacuum cleaners on hand for the more difficult jobs, particularly for carpets and sucking up dirt from nooks and crannies.

Mopping

Like its vacuuming prowess, the Qrevo Edge does a good job of mopping too – again, only if it’s not taxed by too many spills. The regular cleaning jobs of dusty footprints and spilt water is excellent.

This mopping performance is helped by four water-flow levels – Low, Medium, High and Custom/Gentle. I found the Low and Medium weren't very effective for the kind of tiles I had in my test space, as the pads didn’t saturate enough for my needs and barely dampened the floor. While this is excellent for sensitive floor types (like some wood panels), the High setting was perfect for me and that’s what I left it at for the various Routines I set up via the app.

The Custom setting, while allowing you to choose the water-flow level, doesn’t ‘scrub’ as well as the other three and that, again, is good for sensitive floor types. If you do need a better clean, you can set the robot to sense areas of excessive dirt and it will automatically return to do a second mop after it has washed the pads following the first attempt. During my testing, though, this feature failed most of the time.

Depending on your cleaning needs, you can set the bot to mop-only, vacuum then mop, or do both at once. Personally, I’m not fond of the last option as I'm a little paranoid that the mop pads will pick up more dirt and won't get washed properly.

I found that it was also a good idea to assign the order in which it cleans rooms as this can reduce track marks from its own wheels over an area it has just mopped – this can be done in the app by just editing the saved map.

Like I did for vacuuming, I performed a couple of mopping tests to see how well the Qrevo Edge does.

While we usually use ketchup in our standard mopping test, I had none at the time and used oyster sauce instead. I allowed a small spill to dry out a little, but also plopped some of the fresh viscous liquid on another part of the floor to test the scrubbing action on dry and wet messes.

Even with the water-flow rate set at High, the Qrevo Edge had minimal effect on the dried-out sauce on the Standard ‘route’. The route is how the robot moves through a space while cleaning and there are four options for both vacuuming and mopping. After setting the robot to do a 2x mop run in the Deep+ ‘route’ setting, though, most of the dried oyster sauce was cleaned, but not fully. I ended up wiping that spot myself.

Cleaning up a wet spill was another matter altogether. On a default Zone run (which uses the SmartPlan option), the sauce was mopped but, of course, got stuck on the side brush (I’m glad I was able to rinse it), smeared the undercarriage and the mop pads left long, brown streaks as the bot moved on.

After allowing it to go back to the dock for a mop wash, I immediately set the Qrevo Edge to a 2x mop at the High water setting to clean up the remaining mess, which it did well.

I’d expect situations like these are extreme and most users wouldn’t allow their robot vacuum to encounter such messes, but it’s worth noting that it doesn’t handle bigger dry messes well either. For example, I sprinkled copious amounts of talcum powder on a wet bathroom floor, then allowed that to dry completely. On a High water-flow setting, white streaks were left on the bathroom floor, much like the oyster sauce.

While I can’t fault the Qrevo Edge’s mopping issues as it’s not unique to it, I regularly found that it didn’t go all the way to the edge of a room despite the extended mop pads. More often than not, about an inch of floor space along skirting boards would remain unmopped. And that was disappointing, particularly since this robot vacuum comes at such a high price and, conspicuously, has 'Edge' in its name.

Navigation and obstacle avoidance

For a day-to-day regular cleaning run, I found the Qrevo Edge’s navigation to be impeccable. There are two Routes (or paths) you can select in the app when it’s vacuuming or vacuuming and mopping at once – Fast and Standard – but you’re provided four when you opt for mop only – Fast, Standard, Deep and Deep+. These Routes determine how much of the floor gets covered and, after testing all of them, I found that the Qrevo Edge follows the chosen Route correctly.

The Route you opt for will, of course, affect battery life and the app gives you a warning every time you change navigation. Despite that, I personally preferred the Standard (for vacuuming) and Deep for mopping as the results were the best.

Importantly, selecting a 2x cleaning run will automatically prompt the Qrevo Edge to clean in the opposite directions for the two sessions, which I thought resulted in even better results than a single Deep mopping session.

The only time navigation was erratic was if I had chosen a Zone clean for a quick session, which defaults to the SmartPlan navigation. This uses deep learning to determine which part of the zone or room the Qrevo Edge should clean first and I found its movements weren’t as precise on a carpet. It was slightly better on hard floors though.

Still, the SmartPlan navigation is quite efficient. Having learned that there is a medium-pile rug in my living room, for example, the Qrevo Edge always did a vacuum-only clean first on the rug, then went back to the dock to wash its mop pads to clean the rest of the tiled living-room floor. On the rug, though, it wouldn’t always move in straight lines, but I didn’t see that it missed any spots.

The Qrevo Edge’s obstacle avoidance could be better though. While it manages to identify some obstacles in its path and place a marker on the map, this functionality wasn’t consistent. To test this further, I placed its own packing box in its path once and it didn’t add a marker on the map, but it did so for a chair I had moved from its original location.

To check its effectiveness avoiding smaller objects, I ran the standard TechRadar tests of placing a cable, a sock, a slipper (aka flip-flop or thong, depending on which part of the world you live in) and a shoe in the robot’s path.

It nearly swallowed the little sock, which got stuck on the central roller, and because of the sock taking up space on the undercarriage, it ran over the cable without getting entangled. The first time it encountered the slipper, it went over it, but the subsequent times it just pushed the lightweight rubber footwear along in front of it. The shoe was the only obstacle it managed to avoid each time it encountered it on its path.

This shouldn’t come as a surprise though as most robot vacuums have difficulty with the smaller obstacles and would chew up a slim charging cable or a sock. That’s why all brands recommend you pick up the smaller items before you do a cleaning run.

That said, Roborock does call out the Qrevo Edge’s obstacle avoidance, so I expected more. It’s perfectly fine for general cleaning, but the performance doesn’t quite match its high price tag.

The robot can use its onboard camera to take a picture of the obstacle and, when you tap on the corresponding marker (if any) on the map in the app, it will come up. Every time I wanted to try this feature with a specific obstacle, it didn’t place a marker on the map. The only time it worked was for a chair that is permanently a part of the map.

Dock performance

Other than the bit of bad odor I could smell when I hadn’t cleaned out the dirty water the day of the cleaning run, I can’t fault the dock’s performance. There’s plenty of suction that pulls out nearly every bit of dust, debris and hair from within the onboard dustbin.

The only thing I found in the bin after a self-empty was a thin film of fine dust along the sides, which is perfectly normal and can be washed out. Just be sure to fully dry out the bin before placing it back into the robot again.

Even the washing seems adequate. At the time of writing, I’d used the Qrevo Edge for two months, running it a couple of times a week, and the mop pads still look good to me. That said, I found the mop pads looked a lot better after three months of using the Ecovacs Deebot T30 Omni, and I also found the air drying to be more effective in the competition as it uses hot air rather than warm as in the Qrevo Edge.

This means the mop pads take longer to dry on the latter and, if there’s not a lot of ventilation in the area you’ve positioned the robot vacuum, you could smell the pads if there's even a little dampness left. During my testing, I had to increase the air-drying time to eliminate any smells.

Another indicator of how well the mop washing works is the color of the dirty water in the tank – it was always dark brown, even if I ran the robot on subsequent days, thinking the floor wouldn’t be too dirty. Boy, was I wrong.

The dock’s self-cleaning features also includes one for the tray the robot sits on (and uses to scrub the mop pads). That can get grimy too and the 5-minute self-cleaning session means you need the least amount of work to maintain this machine.

Battery life

Battery life is where the Qrevo Edge truly shines. It’s got a 6,400mAh pack that easily did a full clean session on Max suction and Standard/High mop (on a vacuum-and-mop run) in one go in my test space and still had about 36% battery left.

If I set the robot to do 2x cleans at its highest settings, then it would run down to about 12% battery, head back to the dock for about three hours, top up till about 48% and finish the rest of its cleaning. That’s an impressive battery performance in my books considering it was doing power-intensive sessions.

Roborock says that the Qrevo Edge is capable of fast charging (up to 30% quicker than previous models apparently), but I saw no evidence of that during my testing. Considering it took about three hours to get just 40% topped up during my testing, I think the best time to run these kinds of modes is when you’re away for the day – that way, you can return to a clean home and not get impatient with half a job done.

• Performance score: 3.5 out of 5

Roborock Qrevo Edge review: app

• Very detailed app as compared to some of the competition
• Offers plenty of precise control
• Matches system dark mode that looks very classy

Roborock arguably has the best-designed app that I’ve used for a robot vacuum cleaner. When you first download it, it will ask if you want it to match your phone’s system settings, which means it will automatically convert into dark mode and I found that it looks very nice indeed – colors pop and everything is clearly laid out.

It will take time to get used to the app, though, but that’s only because there’s a lot going on. In fact, I kept discovering quirks and better ways to use the robot all through my two-month testing period and I don't think I've still completely figured it out at the time of publication. While my test space was a single-storey home, the Roborock allows you to save multiple floor maps and swap between them, although you will have to go through the Edit Map menu to do so.

Map editing is a lot more straightforward here than I’ve found with other robovac apps, and it identified carpets and hard floors in the test space correctly, requiring minimal intervention on my part. You can add furniture if you wish, but that can be fiddly. The usual features of adding no-go zones and virtual walls are also available.

Diving into what the robot can actually do is time consuming, particularly if you plan to set up custom Routines. The app gives you some default options that you can edit, but it’s not always as straightforward as its map editing.

For example, a couple of full-home routines I tried to set up refused to show me a vacuum-only option, but only gave me a vacuum-and-mop. I had to then break up that option and have two Routines for a full-home clean.

You can always edit those Routines as you learn more about the app, but it really shouldn’t be as difficult as it is currently set up.

Perhaps the best part of the app is the SmartPlan option you’ll see as soon as you select the robot vacuum. While you can run this from the get go, you won’t get the best clean early on.

I found that it’s the most effective after you’ve run the robovac a few times throughout the home on specific Routines. It will use this information, leveraging some AI smarts, to customize the best cleaning path, suction and mop settings for subsequent runs.

There are some other advanced features in the app that you can use, including using the onboard camera to do a quick security check around your home while you’re away. You can guide it remotely using the app navigation, but you can also keep the camera on while it's cleaning.

You can even photograph obstacles or conduct a video call with your pet. The camera features are turned off by default, which is a good thing, and all photos and videos are saved locally, according to Roborock. Moreover, you’ll even need to be the primary account holder to enable these camera features, adding a layer of security.

Roborock has its own voice assistant called Rocky, which is available to use on the Qrevo Edge, but the prompts it can understand are very limited. There are more Siri voice prompts, but even these I found to be a little unreliable. You can connect the Qrevo Edge to Google Home or Alexa, which offers better control but, again, quite limited prompts. In general, I think the app itself should be your go-to for full control of the robot vacuum and its dock.

Roborock Qrevo Edge: alternatives to consider

How I tested the Roborock Qrevo Edge

• Used in single-storey, one-bedroom apartment with mixed flooring
• Used two to three times a week for eight weeks
• Tried various settings and modes, with specific tests for fine dust and larger debris

I used the Roborock Qrevo Edge regularly for a period of two months in an approximately 40sqm one-bedroom apartment that has both full carpet and hard floors (tiles). This test space has no pets, but I did my best to make sure there was enough of my own hair on the carpet to make for tougher cleans.

I also set up several custom routines, running each at least two or three times to test for not just cleaning abilities, but also consistency. I even ran it on some default settings and modes, particularly testing the SmartPlan option several times for Room and Zone cleaning.

I ran TechRadar’s usual tests for suction, mopping and obstacle avoidance, plus did an extra test to test for cleaning fine dust and powder (using talc).

I compared its performance with other robot vacuums I’ve tested previously, having gone from the Ecovacs Deebot T30 Omni directly to using the Qrevo Edge.

Roborock Qrevo Master: two-minute review

Originally launched in May 2024, the Roborock Qrevo Master is a high-end robotic vacuum and mop that produces an impressive blend of power, intelligence and convenience. Boasting 10,000Pa suction, dual rubber rollers and flexible side brush, the Qrevo Master effectively tackles dust, debris and pet hair on a variety of surfaces, while its dual spinning mops and consistent downward pressure ensure a very decent level of hard floor cleaning and light stain removal.

Navigation is always a key standout feature among Roborock models and this one's no different. The Qrevo Master's LiDAR mapping and AI-powered obstacle avoidance allows the bot to maneuver around furniture and most larger household objects. However, when it comes to small obstacle avoidance there are more efficient models out there that perform better in this regard.

The Qrevo Master's self-maintaining dock, meanwhile, adds an extra layer of convenience, automatically emptying the dustbin, refilling the robot's water tank and washing and drying the two mop pads. For those seeking a premium, low-maintenance floor cleaning solution, the Qrevo Master is an excellent choice, and holds its own against the best robot vacuums on the market, despite not being the very newest model out. Read on for my full Roborock Qrevo Master review.

Roborock Qrevo Master review: price & availability

• List price: $1,599 / £1,199 / AU$2,199 (regularly discounted in all territories)
• Launched: May 2024

At list price, the Roborock Qrevo Master costs $1,599 in the US (although at time of writing, it was down to $899.99, which is the kind of price you should expect to actually pay for this model). In the UK it's £1,199, but again you should expect not to have to actually pay that – at time of writing it's down to £799.99. In Australia, the list price is AU$2,699 but it's currently discounted to AU$2,199.

Even at those discounted prices, it's still a premium robot vacuum. However, it's far from the most expensive model on the market – most brands' newest flagship models are well into the four figures in the US and UK.

At time of writing the Qrevo Master is still a relatively new model – it launched May 2024. However, the world of robovacs moves fast, and there are now several newer bots in the Roborock range. It occupies a spot somewhere in the middle of the Qrevo lineup, between the basic and budget-friendly Qrevo Q5 Pro+ and the expensive but excellent Qrevo Curv. The latest options to join the lineup are the Saros 10 and Saros 10R, both of which cost far more than the Qrevo Master and introduce some cool (if not wholly essential) new tech.

While not the best or most advanced robot vacuum in the Roborock lineup, the Qrevo master is still a mighty fine option that delivers on many fronts, not least its excellent navigation and vacuuming skills.

While there are other sterling robot vac manufacturers out there – namely Dreame, Eufy and Narwal – I personally always gravitate to the Roborock brand simply because the Chinese company's products are so reliable and usually ahead of the curve. Where Roborock goes, others follow.

Is the Qrevo Master good value? I'd say it sort of is given that most robot vacs with this level of smarts retail for around the same price. Nevertheless, there are some outstanding cheaper options around if you know where to look. (In the UK, the phenomenal Xiaomi X20+ performs almost as well as the Qrevo Master for around £500 less – it's the best budget robot vacuum I've tested, by some margin).

Roborock Qrevo Master specs

Roborock Qrevo Master review: design

• Slightly basic looking hybrid bot, and a little on the tall side
• Dual rubber brush rollers and rotating mop pads
• Comprehensive dock, including mop cleaning and drying

I guess I've been spoiled by the clean Scandinavian-style design aesthetics of Roborock's latest premium models, the Saros 10 and 10R, because the Qrevo Master's robot unit looks a bit old fashioned with its large, plastic LiDAR unit and oversized bumpers. At 10.3cm in height, it's also quite tall which means it will have trouble passing under some low-slung furniture.

Roborock's newer (pricier) robots outshine the Qrevo Master in this area – the Saros 10 has a puck that can pop up and down, and the Qrevo Slim and Saros 10R don't have a puck at all. All look significantly slicker and more modern than the Qrevo Master.

I'm not too enamored of the medical white color scheme of my review model – I much prefer the back version that appears in the studio photos in this review.

Let's tackle this model's navigation system first. Like all the very best robots, the Qrevo Master uses LiDAR and an RGB camera to find its way around a home, and its accuracy is second to none. In fact you can see the results during its very first mapping run in real time on the Roborock app. The RGB camera can also be used to monitor a room by driving the robot around like a remote controlled car.

However, while the Qrevo Master's large obstacle avoidance (furniture legs, etc) is above par – its Reactive AI software can identify and avoid 62 objects across 20 categories – its obstacle detection isn't as precise as the company's very latest navigation systems. After all, today's technology moves at such a pace that something considered groundbreaking a few months previous is very soon superseded by another that's lightyears ahead.

You do get a very decent tranche of vacuuming tech with this unit, including very effective dual rubber brush rollers with an anti-tangling device and an automatically extendable side brush that pops out in corners of a room. This model boasts 10,000Pa which is short of its higher-end stablemates but still perfectly acceptable for practically all cleaning scenarios, bar perhaps very deep pile carpet.

There are five levels of power to choose from – Quiet, Balanced, Turbo, Max and MAX+. Since the robot's battery is more than up to the task of vacuuming a large space (it has a running time of about 60 minutes in Max mode) , I would always opt for Max or MAX+ because, well, why wouldn't you?

On the mopping front this model comes with two circular toweling pads and, like many current high-end models, one of the mopping pads can also extend outwards to clean along skirting boards and around furniture legs. Both mops are pushed into the floor while they spin at 200rpm, giving any hard floor a good seeing to. This style mop tends to do a more effective scrubbing job than the static D-shaped pad still found on many robot vacuums – even the high-end models.

The mops themselves are pre-dampened by a small onboard 80ml water tank that is in turn filled in the dock just before going out on a mopping run. You can select up to 30 levels of water flow in the excellent Roborock app.

Of course, one wouldn't want any damp mops running slipshod over one's lovely carpets so the mops on this model lift by a few centimeters whenever the bot is traversing carpets or rugs. Likewise, its vacuum brush rollers also rise up whenever the robot is mopping or returning to base.

Dock design

At 521 x 340 x 487mm, the Qrevo Master's dock is considerably taller than many of its peers and that means it will be harder to position without it being too conspicuous. In fact this dock shares some design aesthetics with the Dreame L40 Ultra I reviewed a while back, including a very similar looking dust bag cover. But thankfully Roborock steered away from giving it any tasteless gold colored details.

It's not the most unpleasant looking dock I've seen, but compared to the gorgeous mirrored finish Roborock has applied to its Saros range, it certainly could do with a bit of a facelift. Thankfully the black option doesn't look quite as ungainly because, well, it's black and therefore less noticeable in a room filled with wooden furniture.

Like all good contemporary hybrid robot cleaners, the Qrevo Master's dock offers a fully automated maintenance system that empties the contents of the robot's small internal 220ml bin into the dock's larger 2.2-liter dust bag whenever it has finished a vacuum session. Having a robot with a self-emptying feature is an absolute must, especially if you have shedding pets in the home. Without one you will need to continually empty the robot's tiny bin yourself, sometimes halfway through a cleaning session and, believe me, that's no fun.

Since this model also wet mops hard floors, it comes equipped with a mop cleaning facility that washes both mops with hot water at 60C to break down dirt and bacteria. Aside from emptying the mucky contents of the 3.5-litre dirty water tank, filling the 4-liter fresh water container, and very occasionally removing the entire mopping tray from the dock to rinse and scrub it under tap, there's very little human interjection required with this machine.

Roborock Qrevo Master review: performance

• Very good vacuuming and mopping performance
• Reliable LiDAR navigation but poor obstacle avoidance
• Effective dock with minimal human interaction needed

This robot vacuum does a lot of different things, so to keep everything clear, I've separated this section into a range of different performance elements. I'll start with navigation performance, then move on to obstacle avoidance. Next I'll get into vacuuming and mopping performance and finally I'll cover how well the dock held up during testing.

Navigation performance

Top marks as usual to Roborock for this bot's navigation prowess. From the moment you set it all up – a breeze, it must be said – the bot trundles off without getting lost and quickly maps your entire floor plan in about five minutes. It then returns to its charging station and proceeds to dock as accurately as a spaceship.

I've since placed the Qrevo Master in our village hall – an extremely demanding 127 square metres of wooden flooring – and the Qrevo Master has never once lost its way or missed a section. Sometimes very large spaces with lots of reflective windows can affect a robot vac's LiDAR navigation performance and this usually manifests itself as a strange anomaly on the app's map interface where the room is mysteriously multiplied in size. This happened on a couple of occasions with the Dreame L40 Ultra. By contrast, the Qrevo Master's complex three-room map hasn't altered at all in three weeks of regular use.

Obstacle avoidance

This is the only test where the Qrevo Master showed its Achilles Heel. For my test I used a collection of small and large dog toys, plus a phone cable. At first the Qrevo Master simply steamrollered even some of the larger toys. Activating the 'Pet' setting in the Reactive Obstacle avoidance menu in the app makes a big difference to Roborock bots' detection skills, but I double-checked and I had indeed already selected this option.

I then ran the test again and, for some bizarre reason, it behaved a little bit better – as if it was going through a learning process. Nevertheless, like the vast majority of bots I've tested, it ran right over the small nylon dog bone and failed to extricate itself. And, while it at first appeared to avoid the charge cable, it soon changed its mind and simply ran over it and then dragged it around the rug.

It's difficult to tell why this model had such issues with obstacle avoidance, but in its defense, its day-to-day schedules have always gone without a hitch – when it has encountered a stray dog toy, it's simply pushed them to the side when not actively avoiding them. However, I agree that this is not ideal given the cost of the machine in the first place.

Hence, if you have a messy home with small items littering the floor, you'd be better off with the Roborock Qrevo Curv, the newer Roborock Saros 10R or the Dreame L40 Ultra. All three of these bots excel at obstacle avoidance.

Vacuum performance

For my hard floor test I measured 22 grams of oats, uncooked orzo, cornflakes, flour and a crushed cheese cracker. I then set a cleaning zone in the kitchen and commanded the robot to perform two passes using Max power. While some of the debris was scattered by the spinning side brush (a common occurrence with all robot vacs), it generally performed extremely well, collecting 21g when measured on the scales.

Granted, a few remnants of oats remained and some flour was left in the cracks but this was easily fixed by using a standard stick vac to finish the job. While not as successful as, say, the Roborock Saros 10R or Dreame L40, the Qrevo Master still proved to be very adept at hard floor sweeping.

I then set up a similar medium-pile rug test using the same 22g of ingredients. This test produced excellent results, with 22g back on the scales. However, it had also collected some extra pet hair and dust in the process so I would say pickup was nearer to 21g. That's an excellent result in my opinion. Best of all, I couldn't see any remnants on the rug from head height – and that's about as much as anyone could wish for.

Mopping performance

I'm not a big fan of robot vacs that also mop because I don't believe any of them are capable of replacing a human's ability to deeply wash a hard floor or target a specific area using either an old fashioned mop and bucket or one of those newfangled wet-and-dry cordless mops that are doing the rounds.

For instance, I would never consider going through the rigmarole of sending a robot mop to attend to an accidental spill when I can get the job done in a fraction of the time. However, I can see robot mops being useful at keeping on top of a pre-cleaned floor if programmed to run a series of regular mopping schedules.

Since this model uses two circular spinning mop pads, I knew before even starting my test that it would be efficient enough for a pass. And sure enough it mopped up all traces of the milk and soy sauce mix I spilled on the floor – in a single sweep no less. It even continued to move over the same spot a number of times, just for good measure. However, like most robot mops I've tested, it did leave a slightly sticky but invisible residue behind after the floor had dried. After the cleaning test, the robot duly returned to its dock to have the mops cleaned and dried using hot air to help keep mold at bay.

Dock performance

Since I have two Labradors and three cats, my home is always full of hair. In fact, I often find odd strands of Labrador hair in the most surprising places. As a consequence of all this hair, some robot vac docks I've tested have become blocked due to an excessive amount of hair stuffed into the robots' tiny bins.

If the dock's suction isn't powerful enough, chances are a bundle of hair will block the air intake, either where the robot meets with the dock's suction tube or, more than likely, at the end of its travel where the suction tube connects with the dock's dust bag. This kind of anomaly is easily rectifiable but also unnecessarily messy, especially given the fact that you buy a robot vac to do all the graft so you don't have to.

Well I'm pleased to say that the Qrevo Master's dock suction levels are easily high enough to draw everything out of the robot's bin and into the dock's large 2.2-liter disposable dust bag with no issues whatsoever. (I'd rate it amongst the best robot vacuums for pet hair in this regard.) In fact, the dock's suction was powerful enough to draw a heavy snooker cue tip into the dust bag, and not many robot docks are capable of that level of suction.

As a postscript, I should add that this robot has been employed full-time in our village hall for several weeks now, and the hall's main floor, its kitchen and toilet area have never looked cleaner. The Qrevo Master vacuums this enormous 127 square metre space three times a week and mops it twice a week. At no time has it ever got stuck in five weeks of regular use. It deftly vacuums the entire hall (even beneath a pile of chairs in one corner), keeps the hall's loos spick and span and stays on top of any kitchen mess. This just goes to prove that robot vacs – and mops – are just as suitable for commercial use as they are for domestic settings.

• Performance score: 4.5 out of 5

Roborock Qrevo Master review: app

• Highly customizable
• Easy to navigate
• Extremely comprehensive

I've said it before and I'll say it again – right now there is no better robot vac app for sheer comprehensiveness and ease of use than Roborock's. This app has it all, from scheduling and specific zone tasks, to a myriad of deep customization tweaks. That includes changing the amount of time the bot returns to the dock to have its dustbin emptied, editing the room surface and direction of wooden flooring, adding no-go zones, even adding furniture icons to the map so it looks like something out of the Sims.

Another great thing about this app is that you can programme a set of ‘Routines' like ‘vacuum the lounge' or ‘mop the kitchen' and save them all on the home screen for instant access. Roborock's tech bods left no stone unturned when developing this app and the results speak for themselves.

How I tested the Roborock Qrevo Master

I lived with the Qrevo Master for several weeks to get a real feel for its performance. I also TechRadar's standard robot vacuum tests to assess performance.

The first thing we're looking for is overall suction performance on different floor types. For this, I spilled a selection of loose ingredients on both hard flooring and carpet and observed the results. Did the robot sweep it all up in a single sweep or did it snowplough everything? Did it scatter the ingredients in the process? Did it leave anything behind after a few passes? I then ran similar tests using liquids, to test this hybrid robot's mopping efficiency.

Aside from performance, I also looked at the design of the robot and self-emptying dock, tested the effectiveness of its obstacle avoidance, and considered how quickly it mapped my home's floor plan when first taking it out of the box. I spent time digging into its app to see how extensive and usable it is, and if any improvements could be made.

Roborock Saros 10: two-minute review

Launched in January 2025, the Roborock Saros 10 is a premium robot vacuum with some seriously cutting-edge features. Primary among these is a navigation puck that retracts down into the bot when it senses it's entering a low-height space. That, combined with a suspension system that can bounce it over tall thresholds, means this bot can reach places other robovacs can't.

On test, I found that both these features worked reliably well. And while the pop-down puck will only really come into play in homes with furniture that's a quite-specific distance off the floor, if you do fall into this category then this robotic will prove a game-changer. No more shifting the sofa once every six months to find a horrifying amount of dust sitting below it!

I was also impressed with the Saros 10's cleaning powers. Suction is strong enough to pull large volumes of dog hair off carpeted floors without fuss, and the anti-tangle roller does exactly what it's designed to do. Mopping is good, too, with the lowest mopping modes creating only the lightest mop; perfect for floors that are sensitive to too much moisture. On balance, I still think spinning mop pads (such as those that feature on the Saron 10's sister model, the Roborock Saros 10R) do a better job of scrubbing, but I did like how the additional mini side mop on the Saros 10 got right up to the edges of rooms.

I should also give special mention to the impressive hands-off dock, which not only empties dust and charges the bot (in double-quick time), but also dispenses detergent, washes the mop pads with hot water, and dries them with warm air. All this while looking far more stylish than basically any other dock I've seen in all my time reviewing robovacs.

At list price, the Saros 10 is far from cheap, but it's roughly in line with other brands' top-of-the-range models offering similarly advanced features. If you just want decent cleaning and are happy to take care of some of the maintenance tasks yourself, there are cheaper options to be found. However, if you're after an advanced model that makes use of the very latest tech and requires minimal intervention from you, this might be the best robot vacuum for you. Read on for my full Roborock Saros 10 review.

Roborock Saros 10 review: price & availability

• List price: $1,599.99 / £1,499.99 / AU$2,999
• Launched: January 2025
• Available: Worldwide

The Roborock Saros 10 was one of three new Roborock robot vacuums announced at CES in January 2025, alongside sister model Saros 10R and the Saros Z70, which has a mechanical arm.

At list price direct from Roborock, the Saros 10 costs $1,599.99 in the US, £1,499.99 in the UK, and AU$2,999 in Australia. At time of writing, it isn't available via any third-party retailers, but it may come to Amazon at some point.

That price puts it firmly into the premium bracket for robovacs. In fact, it's one of the most expensive models we've tested so far, although its price is roughly in line with many other brands' top-of-the-range models. Build quality, performance and featureset help justify that price somewhat, and I'm not going to score it down too much on price because I'm glad this kind of innovation exists in the robovac world – plus, it's a truly excellent robot vacuum. Having said that, I'd still hold out for a discount (or for the price to come down over time) before buying one.

This is a super-advanced robot vacuum, and you don't need to spend this much to get an appliance that will keep your floors clean. For most people's needs, there are models at even half the price that will do the job – especially if you're willing to sacrifice the mop washing / drying / self-cleaning dock functions, all of which will bump up the price significantly.

Note, however, that there are a couple of ongoing costs to factor in, too. The first is replacement dust bags, although with a 2.5-liter capacity, each bag should last a decent amount of time. The second is floor cleaner: Roborock recommends you use only its own branded detergent, and I'm disappointed to report it's very expensive.

Roborock Saros 10 specs

Roborock Saros 10 review: design

• Pop-up navigation puck and bouncy chassis for traversing thresholds
• Bulky but smart mirrored self-empty dock, with mop cleaning
• Side mop and brush, and split main roller for directing hair

The bot itself looks similar to your standard disc-shaped robovac, but the main difference here is that rather than having a fixed navigation puck, it has one that can pop up and down. It will generally be up (this allows for better navigation); however, it will retract when the bot is docked and if it senses it's entering a low-height space.

On the front there's also a camera and additional navigation elements. The camera can also be used as a security cam, or to check in on your pets while you're out.

Flip it over and you'll find two chunky wheels and a smaller front wheel, all of which can raise and lower independently to get the bot over tall thresholds. It's designed to be able to traverse thresholds up to a total of 1.6 inches / 4cm in height, including double-step thresholds, using the same AdaptiLift technology included with the Roborock Qrevo Curv. The bot learns the best process for each threshold in the mapped area.

The roller is rather unusual. It combines rubber fins and bristles, and is split in the middle to allow hair to escape into the bin, rather than becoming tangled and requiring you to then manually cut it off.

There's a spinning side brush that tucks itself away when it isn't in use. Again, the design is a little unusual: it has two arms, which sit near each other and extend at a slanting angle, to resist hair from becoming tangled.

For mopping, the Saros 10 has a fixed, D-shaped mop pad. This has two vibrating zones that are designed to help dislodge dirt, and can also press down on the floor. (It's still not my preferred style – I find dual-spinning discs do a more thorough scrubbing job, which is the reason for docking a half-mark in this section).

There's also a tiny extra side mop designed to get closer to the edges of rooms. Cleverly, if you opt for a mode where the mop isn't needed, it can drop the mop off in the dock, so there's no danger of damp carpets.

The panel on the top of the robovac is magnetic, and can be removed to reveal the onboard dustbin. You shouldn't need to access this often – only if the self-empty process fails because something has jammed the mechanism. Presumably there's also a water tank in there, but I couldn't find it.

The Saros 10 dock is one of those does-it-all units that not only charges the bot and empties its small onboard dustbin, but does a whole load more besides. It can refill its onboard water tank, disperse detergent, clean the bot's mop pads (at up to 176ºF / 80ºC), dry them (at 140ºF) over the course of a few hours, and also clean itself (at up to 176ºF).

It's designed to be able to recognize what's on the mop and adjust the temperature to suit; so it knows to use hotter water for grease and coffee stains than items such as mashed potato.

As such, the Saros 10 is fairly bulky. However, it's one of the best-looking docks I've seen, with a smart, mirrored front that simply reflects the rest of your room back at you. So if it looks messy, that's on you.

The dustbag is hidden behind a front flap that opens when you press it, and two large water tanks (one for clean, one for dirty from cleaning the mop) are housed in the top, again behind a door.

There's a removable ramp up into the dock, and inside you can see the brushes for cleaning the mop pad.

Roborock Saros 10 review: performance

• Excellent vacuuming on higher settings; can handle pet hair
• Mopping also very good on higher settings – edge mop is useful
• Navigation great but object avoidance unreliable

Setup was painless. I unpackaged the bot, left it to charge on its dock, and then was prompted to complete a quick mapping run. Here, the bot made its way briefly into each room, looked around a bit, then left. It then provided me with a suggestion of what it thought the rooms were, and their floor types.

I was testing this bot in a town house with multiple levels, so I repeated the process for each floor, carrying the bot up to each level to do so (advanced though this robovac is, it still can't climb stairs).

The initial plans were generally very accurate. After they'd been created, I went back in and corrected room types, removed unnecessary areas (it included the stairs when mapping higher levels, although its cliff sensors reliably prevented it from trying to go down them), and added no-go areas.

Vacuuming

On the vacuuming front, there are five power levels to choose from: Quiet, Balanced, Turbo, Max and Max+ (there's a battery life warning with this mode). You can also opt to clean the space once or twice. I did find this bot a little noisy in vacuum-only mode, but it certainly wasn't any louder than a manual vacuum.

To try out vacuuming, I first set off the Saros 10 to clean each floor of the house, using a mix of different power levels, in vacuum-only mode. After cleaning, and before the bot returned to the dock, I inspected the onboard bin to see what it had gathered collected.

I found Turbo mode was enough to extract plenty of dog hair from carpeted floors, and even more if I amped it up to a higher power mode. I was also impressed that the bot had no trouble auto-emptying, even when full with hair. I could hear the tell-tale "whoomph" sound as the wodge of dog hair made its way from the onboard bin to the dock dustbag.

I was also generally impressed by the roller design – there was next-to-none of my long hair wrapped around it at the end of a vacuuming session. That isn't the case with some of the robovacs I test.

To test how the Roborock Saros 10 handles different kinds of debris, I ran TechRadar's standard suction tests. I sprinkled a teabag of dry tea on the carpet, alongside a handful of oats. I then ran the vacuum over them. On first pass in Turbo mode, the results were a little disappointing – the bot failed to pick much up, and what it did, it spat back out on a different area of carpet.

I ran another spot clean in Max+ mode and was far more impressed. This time, the bot picked up most of the debris, both large and small. To be clear, this is a tricky test. I went back over the tea spillage area with my Dyson Gen5detect vacuum and even that struggled to get the very last specs of tea from the carpet.

It's worth pointing out here that, in general, robot vacuums are designed for maintenance cleans – for deep cleaning, you'll still want to keep one of the best manual vacuums to hand. Among robot vacuums I've tested, the Saros 10's suction performance in general was very good.

I ran the same test with tea and oats on a hard, tiled floor. This time, the bot picked up almost everything first time in Turbo mode, albeit with a fair bit of flicking around of debris. The only remaining bits were in the grouting cracks, and I managed to get those by remote-controlling the bot over the relevant area afterwards.

To assess this bot's edge-cleaning powers, I sprinkled team and oats along the edge of the tiled kitchen. It did a pretty good job of clearing it, although it did ping everything around a bit, and there were a few remnants left that it was quicker to tackle with a manual vacuum that try and get the bot to handle.

Mopping

There are four mopping levels to choose from – Mild, Standard, Intense and Extreme. These increase not just the amount of water used, but also the enthusiasm of the scrubbing. Standard mode is really very light; I found the floor had almost completely dried by the time the bot had finished cleaning the room.

That's great news if you have floors that are sensitive to too much moisture – wooden floors, for example. However, if that's not the case and you want a more thorough mop, you'll want to deploy one of the higher mopping modes.

You can choose for the bot to mop only, vacuum first and then mop, or do both at once. I tend to avoid combination mopping and vacuuming since it will often lead to messy rollers and side brushes, due to the combination of water and dry debris. In mop-only mode, the Saros 10 really is extremely quiet.

On test, I found it could take a while for the mop pads to fully saturate, and especially in Standard or Mild modes. Initially, I could see damp streaks on the floor where the bot had cleaned incompletely. However, the tiny extra side mop does a good job of getting right up to the edges of rooms.

For my mopping test, I smeared a tiny bit of ketchup on a tiled floor and left it to dry. After one pass in Standard mode, the Saros 10 had hardly cleaned up any of it. Amping it up to higher mop levels yielded better results.

On balance, while this bot does a good job of mopping, I still prefer the spinning dual disc-shaped mop style when it comes to pure scrubbing power.

Navigation and obstacle avoidance

The pop-up puck is an interesting one, because in reality it's a very specific situation in which it's actually useful – you need furniture that's taller than 3.3inches / 8.2cm but shorter than 4.5inches / 11.4cm (the height where the puck wouldn't need to retract) off the ground. If you have that, though, it's super useful.

There's only one piece of furniture in my testing house that falls into the correct bracket, and the puck worked exactly as stated here. It also didn't impede navigation at all, although said piece of furniture is quite small, so it probably didn't present the biggest challenge.

I also ran TechRadar's standard obstacle avoidance tests, placing a sock, a charge cable, and a shoe on the floor, spread apart. I also added a box of tissues, for good measure. Results were mixed here.

The bot tried to eat the sock. It successfully identified and avoided the shoe, and at first also the tissue box, although it then went back and pushed it around a bit.

The Saros 10 also chewed the cable. That isn't a massive surprise, because I've yet to come across a robot vacuum that can successfully spot cables. However, it's something Roborock specifically states the Saros 10 can do, so it's disappointing in this regard.

In general use, however, I found this robovac pretty good at obstacle avoidance. There are various bins, speaker bases and ornaments on the floor that it successfully avoided – but as mentioned, it isn't quite the "exceptional" obstacle recognition and avoidance promised by Roborock.

Advanced features include the ability to use the robot to hunt out, photograph, and even video-call your pet. I did not try these features, because I suspect the dog would find such an intrusion wildly unsettling rather than reassuring.

Any photography and video features are turned off by default. To enable, you have to manually press some buttons on the robot vacuum, and you also have to be the primary account holder.

Battery life

I can't fault the Saros 10's battery. While it's less of an issue with robot vacuums than a cordless stick vacuum – because the bot will automatically return to the dock to charge whenever it runs out of juice, before resuming its cleaning task – it's still helpful for a robot to offer decent runtimes. That's especially true if you're going to use it in a house with multiple floors, where it can't always get back to its charge dock without help.

The Saros 10 managed an impressive amount of cleaning on a single charge. I was concerned that the Max+ mode – which comes with a "battery draining mode" warning – would run the battery down super quickly, but on test it trundled through three complete room cleans in vacuum-only Max+ mode (from a not-full battery in the first place) before running out of juice. Impressive.

Roborock also promises fast charging; it claims the dock will take the robovac from flat battery to full in 150 minutes. On test, I found this accurate. I went from 14% battery (at which point the bot told me it needed to return to dock to recharge) to 100% in under two and a half hours. If it goes flat mid-task, the bot will also figure out how much more power it needs to complete the task, and only charge to that point, for maximum efficiency.

Dock performance

Based on a couple of weeks of testing, the dock seems to be performing as stated. I've experienced no issues with the bin failing to empty completely, and the washing function seems to be working as claimed based on how clean the mop pads look and how dirty the water in the waste water tank is.

I'll update this section when I've been using the bot a little longer, and have a more complete view of the dock performance over time.

Roborock Saros 10 review: app

• Lots of settings for precise control
• ... but will also figure things out automatically, if you prefer
• Generally very usable, with a few usability quirks

The Roborock app is well designed and nice and usable, although it can take a little time to learn your options and explore all the settings at first – in part because there are so many of them. There are also a few areas I found unhelpful. For example, to swap between different floorplans in a multi-storey home, you need to go via the "edit map" menu, which feels unintuitive.

Otherwise, mapping is straightforward, and you have the option to set no-go zones and invisible walls, as well as removing sections that are added in error. You can also add furniture, and create cleaning preferences for different rooms and floors.

Strangely, you can't manually select the floor type for each room. You can create "carpet areas", but this is fiddly – no areas can overlap, making things tricky if the plan includes carpet rooms and hard floor rooms. The app will automatically identify floor type, but the areas that have been designated as carpet isn't always clear. I'd prefer to be able to set this as a backup – no one wants a mopped carpet.

A relatively new addition to the setup is SmartPlan 2.0, which uses AI to customize the cleaning route, suction power and mop settings based on the bot's knowledge of its environment and previous use. Roborock says it can even reduce suction power during designated "quiet hours".

In short, you can have as much or as little control as you want here. If you don't want to get involved, you can basically leave the bot to figure out everything on its own, and it will do a very good job. Alternatively, you can really dig into the different features and set up everything exactly as you want it.

Roborock Saros 10: alternatives to consider

How I tested the Roborock Saros 10

I used the Roborock Saros 10 regularly for two weeks in a four-storey town house that has a mixture of carpeted and tiled floors, and houses a very hairy cocker spaniel. I used it to map and clean each of the levels, exploring the different settings and modes. For a more objective performance review, I ran TechRadar's standard suction tests (using dry tea and oats on hard and carpeted floors), mopping tests (using ketchup and juice on a hard floor), and obstacle avoidance tests (using socks, a cable and a shoe). I compared my experience of the Saros 10 against other robot vacuums I've tested, in terms of both ease of use and cleaning performance.
