Eufy X10 Pro Omni review: two-minute review

The Eufy X10 Pro Omni is a quality robotic vacuum and mop. It has excellent suction power, while also being pleasantly quiet in all but its most powerful setting, navigates around obstacles very well indeed, and even reports back with photos of objects it has avoided. The mopping system is especially good, with two rotating pads that press down onto the floor with 2.2lbs of pressure and spin at 180rpm. The result is a top-notch clean with no puddles or streaking.

The base station is larger than some others, including that of the Eufy X8 Pro, but is nicely designed and houses tanks for both clean and empty water for the mop. The robot's navigation system uses a camera and LiDAR to precisely map your home and quickly creates a floor plan that can be edited in the Eufy Clean app – it's then easy to name rooms and create no-go or no-mop zones.

As with other Eufy robots, the X10 can struggle to climb over larger doorway thresholds. This in itself isn't a major problem, but the issue is how the robot sometimes manages (more often than not, to be fair), yet sometimes fails. Some adjustments to your thresholds might be required if your floors are particularly uneven.

Overall, the X10 Pro Omni is a high-end robotic vacuum with excellent performance, especially when it comes to mopping hard floors. The base station is large, but offers a complete, hands-off cleaning experience.

Eufy X10 Pro Omni review: price & availability

• List price: $799.99 / £799 / AU$1,699.95
• Availability: Available now

The X10 Pro Omni sits above the Eufy X8 Pro but below its new flagship, the Eufy Omni S1 Pro. At $800 / £800 it's a little more expensive than the X9, but falls comfortably below the S1, to the tune of over $500 / £500. The X10 Pro Omni’s list price is also comfortably below that of the four-figure Roomba Combo J9+.

Splashing out a four-figure sum on a robotic vacuum might sound absurd – especially when entry-level models start below $300 – but such figures have quickly become table stakes, and at $800 the X10 Pro Omni feels like fairly good value. Especially when the new S1, which is also a robotic vacuum and mop with self-emptying of both its dustbin and water tank, costs a whopping $1,500.

Eufy X10 Pro Omni review: design

• D-shaped vacuum with single side brush
• Two rotating mops
• Charge station empties bin and water tank

The Eufy X10 Pro Omni is a D-shaped robotic vacuum with a roller brush and two spinning mops underneath, plus a single rotating brush on its side for flicking dirt out from the corners of your room. When in use, the two mops push down with a force of 2.2lbs (1kg) and spin at 180rpm to scrub dirt away from hard floors.

The robot’s vision system includes LiDAR technology, so it can see just as well at night as it can during the day, and the mops automatically lift when it drives onto carpets to avoid getting them wet. A specially designed comb is intended to automatically remove hair from the roller brush, preventing it from getting tangled up.

A base station is included and charges the robot and also empties the dustbin, dries the mops with warm air and swaps out the robot’s dirty water for clean. Eufy says the base station's 2.5-liter dust bag only needs replacing every two months, based on a three-person household without pets, or 45 days with one pet and 30 days with two. It also states that the 3-liter water tank provides enough water to mop a 1,500-2,000sqft home two or three times.

Everything feels well made and it’s easy to get the robot set up and ready for its first clean. The base station isn’t particularly attractive – and it's also quite large. That said, I prefer the X10’s simple design over the transparent, glowing water tanks of the Eufy S1 Pro Omni.

The base station measures 18.1in (460mm) tall, but requires an extra 13.7in (350mm) above that to access the dustbin and water tanks. The station is 14.4in (366mm) wide and 18.9in (480mm) deep, including the ramp used by the robot to drive into its charging dock. The robot itself is 4.47in (113.5mm) tall, including the sensor housing, and has a footprint of 12.87 x 13.9inc (327 x 353mm).

As ever with Eufy robots, the base station needs about 20in (50cm) of free space either side, so it can drive up against the wall, and 59in (150cm) in front, where it needs space to drive out from the charger and orient itself before each clean. In reality, you can get away with placing the charge dock in the corner of a room, right next to a wall. The robot still works just fine, but won’t be able to clean between the station and the wall.

Lastly, the robot’s dust bin is easily accessible by opening the lid (which is held closed with magnets) and pulling it out. From there you can retrieve any debris that's got stuck and access the filter, which requires occasional cleaning. Water is automatically fed in and out of the robot when docked at the base station, so there’s no removable tank (as there is with the cheaper Eufy X8), and the mop pads can be removed to be cleaned and eventually replaced.

Eufy X10 Pro Omni review: performance

• Intelligent navigation
• Scales uneven thresholds (most of the time)
• Excellent cleaning performance

Before I tested the X10 with a set of specific tasks, I used the robot for a couple of weeks as any regular customer would. This included setting it up in my kitchen and using it to periodically clean individual rooms, along with the occasional whole-home deep clean.

Right away, the X10 impressed. The robot quickly and accurately mapped my apartment during its first exploratory clean, using the LiDAR sensor to work out where all the walls and furniture were, and even splitting the floor plan into rooms. I then used the app to name each room and set a no-go zone under the sofa, since there’s so much stuff back there I’m always worried about robotic vacuums getting stuck. The X10 never did, but I’d rather it doesn’t try picking a fight with the random DIY tools, paints cans and pieces of wood from our recent kitchen installation still lurking under there.

I also initially set no-mop zones for the carpeted bedroom and a large rug in the lounge, but soon learned to trust the X10’s ability to spot the difference between hard floors, carpets and rugs. A couple of weeks later, and it hasn’t once tried to inadvertently mop the carpet.

I’ve also been impressed with the robot’s navigation, and how it stops instantly if something gets in its way. Step in front of it and it stops on a dime, before quickly working out an alternative route. It’s also good at climbing over uneven doorway thresholds. Eufy’s newer and far more expensive S1 Pro Omni really struggled with thresholds and climbing from exposed floorboards to carpet; so much so that it sometimes completely failed to enter certain rooms.

The X10 is far better in this regard, but was still inconsistent in its ability to clear raised thresholds. When tasked with a whole-home clean it would manage just fine, but when asked to clean only the kitchen it would drive down onto the floorboards of the hallway, then repeatedly fail to climb back over the circa-2cm threshold. Sometimes it would succeed, only to drive back down and get stuck again.

As with the S1, I wouldn’t mind if the robot accepted defeat and admitted failure every time, but instead its ability to clear the threshold is inconsistent.

The vacuuming performance felt about on par with the S1, especially when turned up to Turbo or Max settings. While a fair bit louder than the Quiet and Standard modes, the more powerful settings produced a deep clean, reliably sucking debris, dust, hair and fluff out of carpets. I also found it works best when configured to vacuum each room twice with either the Standard or Deep intensity setting. I would say the X10’s vacuum performance is about on par with my Dyson V10, and I was especially impressed with its ability to pull fluff and hair out of carpet. That said, the Dyson still picked up some extra dust and hair when used right after the X10 had completed a job at maximum suction.

You’ll also still need a manual vacuum for areas that robots like the X10 simply can’t reach, such as tight gaps between furniture and the stairs. As ever, these robots are great for light, frequent cleans – and free up a nice chunk of your time in the process – but can’t replace a manual vacuum entirely.

I found a single pass with the Fast setting is fine for a quick daily clean, and I can see this working great for little-used spare bedrooms. But for my one-bed flat, where every room is used frequently, a more intensive clean works best. I also found it did a great job of avoiding all manner of obstacles. Eufy says the robot can recognize over 100 types of objects, from toys and cables, to clothes and the all-important pet mess. However, during one clean it mistook a small plant pot for a bin and a stray sock for a shoe. It also labeled a fireplace hearth as a "base" and steered well clear of it, missing a patch of carpet in the process.

The X10’s mopping performance is particularly good, thanks to how the mops press down and spin quickly. This is far more effective than the static mopping pad of the Eufy Clean X8 Pro, which is simply dragged around. The X10 gives hard floors a proper clean, and I like how it drives in a pattern that ensures the mops, which are at the rear of the robot, are pushed into corners and up against the walls at every opportunity.

Now for the specific tests, where flour, biscuit crumbs and oats are used to see how robotic vacuums perform in controlled conditions. First, I combine flour with biscuit crumbs and sprinkle the mix on a patch of hard floor, then ask the X10 to clean that area with its least powerful suction setting, which I recorded at about 62 decibels.

The X10 did an okay job, and took just a couple of minutes to vacuum the whole kitchen, but missed a few obvious patches of crumb mix. I tried again, this time using Standard suction (64dB) and with it set to clean the same area twice instead of once. I’ve found from other vacuum reviews that this makes a huge difference, as debris flicked around on the first pass is often collected on the second. The result this time was better, but some debris remained. 

Finally, switching up to Turbo suction (66dB) and enabling deep cleaning, where it drives a more thorough route across each room, completely cleared the crumb mix and left the floor perfectly clean. As for other sounds, the vacuum briefly hit a rather loud 82dB while emptying its bin into the base station, then settled down to 62dB for a minute to clean the mop, and a barely audible 42dB while the mop was dried with hot air.

I then performed the same test on carpet and saw similar results. The less powerful suction modes are best for frequent, light cleans of lesser-used parts of your home (like the spare bedrooms), while the more powerful settings work great in higher-traffic areas or for spills. I was again impressed with how well the X10 sucks debris out of carpet.

I was less impressed by how it handled larger debris. Like other robot vacuums, it had a habit of flicking oats around the room instead of collecting them up. The rotating brush does a decent job at collecting dust and hair, but fails to pull larger debris, like the oats, away from the edges of a floor and into the robot’s path. Instead it often does the opposite, pushing debris into the corners and up against furniture where it is more difficult to reach, especially on floors where the carpet slopes downwards at the edges.

Larger debris like this requires maximum suction, as even Turbo mode struggled to pick everything up – not including the oats flicked to the corners of the room. As ever, the conclusion is that robotic vacuums are great for simple cleaning but can’t match a manual vacuum for clearing up specific spillages.

Finally, I tested the mopping function by spilling a sugary drink and some hot sauce on a wooden floor and leaving the mess to dry. I set the robot to mop the kitchen and it did a fantastic job, completely removing the stains and using just the right amount of water to clean the floor without leaving any streaks or puddles. It then took just a minute or so to clean the mop, and spent a couple of hours drying them. As with the Eufy S1, the X10’s mopping function is flawless, and far better than the static mop of the X8.

• Performance score: 4 out of 5 

Eufy X10 Pro Omni review: app

• Easy to use
• Lots of configuration available
• Handy pre-set cleaning scenarios

Just like the X8 and S1, the X10 is controlled by the Eufy Clean smartphone app for iOS and Android. It’s one of the better smart home companion apps I’ve used, thanks to it being intuitive and easy to use, but with lots of customization available to those who want it.

Such configurability includes setting the X10 Pro Omni to clean whichever rooms you want, however you like. For example, you can ask it to vacuum and mop the kitchen with deep intensity, Turbo suction and medium water usage, and for it to make two passes on each stage of the clean, then head into the lounge and do a standard vacuum.

I especially like how you can create shortcut icons for specific cleaning scenarios. For example, you can create a scenario called Post-Meal Clean, where the robot will perform a quick, low-intensity clean of your kitchen (or whichever bit of floor space you want) with just a tap. There are also scenarios for deep or daily cleans for the whole home, and you can make your own too.

It’s also easy to split your home map up into sections and name each room accordingly, and to create no-go or no-mop zones to stop the robot doing anything wrong. The Eufy Labs section includes a couple of experimental features, including one called Smart Track Cleaning, where pressing the robot’s front bumper with your foot for three seconds turns it on and has it follow you, cleaning as it goes.

Lastly, the app can be used to manually control base station functions. This is handy for if you’ve had to pick the robot up and return it to its charger for whatever reason, or if you have disrupted its cleaning routine. With a couple of taps it’s easy to have the station empty the robot’s dustbin and wash then dry the mops – which it does very effectively by blowing them with air heated to 45C for around two hours.

How I tested the Eufy Clean X10 Pro Omni

I set up the X10 Pro Omni and used it as my only vacuum and mop for a couple of weeks. During this time I let it create a map of my own, then named rooms and created no-go and no-mop zones.

I then experimented with all of the various vacuuming and mopping modes, before conducting several specific tests to learn exactly how well each mode performs, and how buyers can get the most out of their robot.

Eufy Clean X8 Pro robot vacuum: two-minute review

The Eufy Clean X8 Pro is a powerful robotic vacuum cleaner and mop with LiDAR for smart navigation and a self-emptying bin for hands-free cleaning. The setup process is seamless, with quick and accurate mapping. The app works very well indeed; it is quick, intuitive and makes it easy to adjust your maps and tweak settings, as well as create cleaning schedules and adjust the suction strength.

The vacuum performs well, with very high suction strength, intelligent navigation and the ability to drive over relatively high door thresholds and through medium-thickness carpets and rugs without getting stuck. However, the anti-tangle roller brush can’t handle human hair, and requires frequent manual cleaning.

We also encountered an issue where the robot got confused and added phantom rooms to the map, which required a factory reset. The mopping function is rather basic, since it requires manual fitting and doesn’t move or self-clean. It’s fine for frequent, low-intensity wipes of hard floors, but isn’t suitable for removing dried-on stains.

Overall, the X8 Clean is a compact but powerful robotic vacuum with a top-drawer smartphone app and impressive cleaning abilities, but it falls short compared to today's best robot vacuums when it comes to dealing with human hair. 

Eufy Clean X8 Pro review: price & availability

• List price: $649.99 / £599 / AU$999.95
• Availability: US, UK, Australia

The Eufy X8 Pro hit the market with a US retail price of $649.99, but at the time of writing (July 2024) Eufy’s own website has $250 off, taking the price down to a far more affordable $399.99. At that lower price it feels like excellent value for money.

Elsewhere, the vacuum is priced at a rather steep £599 from Eufy’s own UK website, but at the time of writing it’s just £290 from Amazon. Eufy’s Australia website has it priced at AU$999.95.

As with other robotic vacuum cleaners – and non-robotic ones too – there are some ongoing costs to consider. This includes the dust bags used by the self-emptying system, as well as consumable components like the robot's side brush and roller brush.

In a world where four-figure robotic vacuums aren't uncommon, some of the deals we've seen make the X8 Pro feel like very good value for money.

Eufy Clean X8 Pro review: design

• Self-emptying charge dock
• Mop attachment fitted manually
• 4.5-inches / 11.4cm tall

The Eufy Clean X8 Pro is a circular robotic vacuum cleaner with an attachable mop. It can be bought on its own or, as reviewed here, with a self-emptying station for an even more hands-off experience.

As with many other robotic vacuums, the X8 Pro has a circular vision system on top. In this case the system is called iPath and it uses lidar and infrared technology to view its environment and work its way around your home. The top panel is also home to buttons for starting/pausing the robot, activating the spot cleaning function, and instructing it to return to base and charge its battery.

The robot measures 13.5 in (34.3 cm) in diameter and is 4.5 in (11.4 cm) tall, including the top-mounted sensor module. This makes it slightly taller than some other robotic vacuums, especially those with their vision system on the front instead of on top, so you’ll want to bear this in mind if you have any particularly low furniture. Eufy recommends creating no-go zones in the app to prevent the robot driving under furniture that is lower than 12cm. You'll also need to set no-mop zones in carpeted areas.

The hinged top cover lifts up to reveal access to the dust bin, which lifts out for manual emptying and filter replacement. Handily, the robot says 'dust bin removed' and 'dust bin inserted' to let you know what you’re doing.

Turn the robot over and you’re greeted by the centrally-mounted roller brush, single spinning brush for flicking debris out of the corner of your rooms, and two wheels.

Since this X9 Pro also works as a mop, the water tank is removed by sliding it out from the rear. You’ll need to fill and empty this manually, and also attach the included mopping pad when you want to use that mode.

The charging and self-emptying station measures approximately 15in (38cm) tall, and is 7.5in (19cm) wide and 6.5in (16.5cm) deep. It is designed to be placed up against a wall, and although not compulsory, it comes with a clear plastic mat onto which the robot and charge station can sit. The mat has sticky pads for fixing it to hard floors, or it can help protect carpets from the damp mop.

The station is more compact than some other models, not least that of Eufy’s S1 Pro, since that model also houses tanks for clean and dirty water. All you'll find in the X8’s base station is a compartment for the included 2.5-liter dust bag, which Eufy says should need replacing roughly every six weeks, depending on usage.

• Design score: 4.5 out of 5 

Eufy Clean X8 Pro review: performance

• Powerful but quiet suction
• Solid navigation capabilities, but sometimes fail to spot all debris
• Mopping is basic

My first task for the X8 Pro was for it to map my apartment. It did this very well, and soon beamed a floor plan back to the Eufy Clean smartphone app (free for iOS and Android). From there it’s easy to split the floor up into rooms and name them accordingly, and you can also have the robot create a map for each floor of your home, if applicable.

After that, it’s easy to either start the robot right away, or create a custom cleaning mode for each room. You can, for example, tell the robot to always use Turbo or Max suction power for the kitchen, pass through the bedroom twice at Standard suction, then clean the lesser-used guest bedroom once with Quiet mode, the least powerful of the four vacuum settings.

A mopping mode can also be assigned to each room, with three options – low, medium and high – on offer. These refer to how much water the robot uses, but since the mop doesn’t actually move (the robot simply drags it around), water quantity is the only variable on offer.

Alternatively, you can draw a specific zone for the robot to clean in, which is useful when you need to vacuum a certain bit of carpet, or when perhaps only the rug needs attention on an otherwise clean hard floor. For the most part, you’ll likely just set the suction power, enable BoostIQ (which increases power depending on debris quantity and floor type) and hit the Auto button. The robot will then vacuum the entire floor plan, before returning to base to empty its bin and recharge.

The robot can even be driven manually, using directional buttons in the app, but you’ll likely only use this once for the novelty value.

Before performing specific tests with carefully measured amounts of debris, I used the Eufy X8 Pro as if it were my own for a couple of weeks. This meant setting it up, then having it clean my flat on automatic mode every couple of days – and let me tell you, its vacuum performance was seriously impressive.

Unlike the (much) more expensive Eufy Omni S1 Pro, the X8 never failed to climb up from the floorboards of my hallway onto the bedroom carpet. The S1 was a bit hit-and-miss in this aspect, and would sometimes get stuck in a relatively thick rug, but the X8 just soldiered right on, turning up the suction when it encountered said rug, or clambering onto the bedroom carpet from the bare floorboards of the hallway. It sometimes got stuck among the frankly embarrassing amount of stuff under the sofa, but never failed to eventually free itself and carry on with the job.

I was also impressed with the X8 Pro’s ability to judge tight gaps, as it would pass through a half-opened door with just 0.4in (1cm) of clearance on either side. That said, it likes to gently bump into its surroundings, seemingly feeling its way around. This is mostly fine, and didn’t cause any damage, but it had a habit of squashing shoes under a bookcase in the hallway.

At one point it spent several minutes fighting with the power cable of a floor lamp. I can’t decide if it’s smart enough to repeatedly try and break free, or dumb enough to not realize what was going on. I suspect the latter, so while I admire the X8 Pro’s ability to keep on going without calling for help – as the S1 Pro does more frequently – I urge buyers to exercise caution and clear away cables before letting the robot loose. Incidentally, if it gets tangled up and needs your help, it stops cleaning as soon as you pick it up, then resumes when you tap the play icon in the app.

Eufy describes the X8 Pro as offering 'tangle-free cleaning', thanks to a roller brush and comb that 'detangles hair automatically', meaning there’s apparently 'no more need to manually clean the roller brush yourself'. This is not entirely true, however, as even in my pet-free home the brush became tangled with human hair after just a couple of cleans, resulting in the robot stopping and asking for help. This only took me a moment to fix, but had I not been at home it would have aborted its cleaning job and headed back to base.

Just 30 minutes later, and the X8 Pro again asked for its brush to be de-tangled, before failing for 15 minutes to find its way back to the charger. Even after I told it to head home via the app, it pondered around a couple of rooms before eventually finding the base station. I thought all was well, but the next morning realized it hadn’t parked properly, despite there being no obstacles, and therefore failed to charge.

I was disappointed by how the robot became tangled up with just a small amount of hair. It seems most hair manages to pass through the brush and into the bin successfully, but when just a small amount remains on the brush the robot stops and calls for help. Eufy promotes the X8 Pro as a vacuum for dealing with pet hair, but in my experience just a small clump of (admittedly long) human hair is enough to render it disabled. This is a shame, because it otherwise performed very well.

Now for the more specific tests, and to see how the X8 Pro’s twin, 4,000Pa turbines get on. My first test was to see how effectively the vacuum sucks up a dry, dusty mixture of flour and biscuit crumbs from a hard floor. The lowest suction mode (recorded at 65 decibels) did a respectable job and picked up most of the debris, but left a few patches. The X8 also managed to flick debris away with its rotating brush, rather than push it into its own path. 

I repeated the test with the next most powerful setting, called Standard and recorded at 68 decibels. It did a better job, but still failed to collect debris from in front of its base station. This is a common theme with the X8 Pro, as it seems unwilling to produce any suction while maneuvering in and out of the charger.

The same thing occurred when using the Turbo (67db) and Max (69db) settings. I found the solution was to set the vacuum to perform each clean twice, which is easy to do thanks to a '2x' icon in the app. That way, any debris flicked around on the first pass is collected the second time around. Smartly, instead of just following the same route twice, the robot covers the majority of the floor by zig-zagging left to right on its first pass, then up and down on its second.

I then tried to repeat this test on carpet but, bizarrely, the robot failed to find its way from the charger in the kitchen to the neighboring bedroom, a journey it had made many times before. Instead it drove around aimlessly for several minutes and began adding new, made-up rooms to the map, compounding the confusion. Since map editing only goes as far as merging, dividing and naming rooms, I had to delete the map for my entire flat and create a new one. There’s a ‘revert’ button in the app, but since this was grayed out it couldn’t be used.

I don’t know what went wrong here, as nothing was relocated or otherwise interfered with between tests. I had to perform a factory reset and have asked Eufy for input on what they think went wrong. I’ll update this review if I get a response.

With the flat remapped, the robot did a great job of vacuuming up debris from carpet, with standard suction and the two-pass technique working a charm, even on hair.

Next, I tasked the vacuum with clearing up larger debris, in the form of oats. I repeated this on the same hard floor and carpet as before, and it did a good job. The rotating brush still had a habit of flicking debris around the room, especially on hard floors, but this is a fault of pretty much all robotic vacuums. Perhaps they should only use their rotating brushes when driving along a wall, instead of in open space.

Finally, the mop. Unlike the much pricier Eufy S1 Pro, the X8’s mop feels like a bit of an afterthought. It has to be attached manually and, unlike the S1’s, it doesn’t move or clean itself in any way. You also have to fill and empty the robot’s water tank manually. In my tests it did an acceptable job of keeping hard floors clean, but this robot should not be used to mop up fresh spillages, as it vacuums first, then mops. Also, because the center of the mopping pad is thicker than the outer edges, it doesn’t clean evenly.

Instead, this is a machine for frequent cleaning – a little-and-often approach, instead of being called upon to tackle something more substantial. I imagine most buyers will relegate the mop attachment to a cupboard and accept that that’s a job they’ll have to do manually for best results. If you want a great robotic mop, the Eufy S1 Pro is far better suited.

Eufy claims up to 180 minutes of battery life, but I found half that is more realistic. As an example, 30 minutes of cleaning took the battery from 90 to 62 percent.

Eufy Clean X8 Pro review: app

• Easy to set up and use
• Can schedule cleans and target individual rooms
• Offers lots of configurability

As with the pricier S1, the X8 Pro is controlled via the Eufy Clean app, which is intuitive to use and works really well. It’s easy to control how the robot functions (suction strength, which rooms to clean, etc.) and there are plenty of settings to adjust to help you get the most out of the robot. You can set a daily or weekly schedule, tell it to only clean a specific room, or clean a designated area of your choice. All that’s missing is the option to have the robot mop and not vacuum. Instead, no matter which setting you pick, it’ll first vacuum then mop.

The app also acts as a service center for your robot, clearly showing how far through their lifecycle each of its components are, including the dust bag, filter, side brush and rolling brush. The app tells you how many hours of cleaning each item is still good for, and there are links to purchase replacements. There’s even a tool to help find your robot, should it have somehow got itself lost under the sofa.

My only wish is that the phantom rooms plotted by the X8 Pro during my testing could be removed without creating a whole new map.

How I tested the Eufy Clean X8 Pro

I set up the Eufy Clean X8 Pro in my apartment and used it as my only vacuum cleaner for a couple of weeks. After this, I conducted several specific tests to see how well it worked in each of its four suction modes. I also tried out the mopping feature and recorded the volume of both the vacuum itself and the self-emptying bin.

I closely observed how the robot tackled different types of debris and how it navigated between rooms with different flooring.

Eufy S1 Pro robot vacuum: two-minute review

• View Omni S1 Pro at Eufy

The Eufy Omni S1 Pro (or just Eufy S1 Pro if you're not in the US) is a robotic vacuum cleaner and mop with a docking station that automatically empties the dust bin, replenishes the water tank with clean, ozonated water, dries the mop and charges the battery after each clean. It uses lidar to help with navigation around your home, creates accurate maps of every room (even across multiple floors) and employs the Eufy Clean smartphone app to let you set schedules and customize how you want the S1 to clean. I tested one out to see how it performs in practice, how it compares to the rest of today's best robot vacuums, and if it justifies its premium price tag.

On test, I found the S1 to mop hard floors incredibly well, thanks to its rotating mop that spins at high speed and pushes down onto the floor with 2.2lbs (1kg) of force. The S1 also does a good job of vacuuming, with four suction strengths available and two rotating brushes for getting into the corners of every room. The Eufy Clean app works very well, and so too does the docking station, which adds a cleaning solution to water before it’s pumped into the robot.

The S1 navigates effectively, driving close to walls without crashing into them and avoiding steps, while automatically raising its mop when driving over rugs and carpets. Its ability to clear raised room thresholds can be inconsistent, however, with the robot sometimes failing to enter rooms it has previously driven into without a problem. This can be fixed by turning off an anti-drop function. It also struggled a little when tasked with vacuuming up fine, engrained debris, and it sometimes failed to spot obvious, medium-sized debris.

The lower suction modes are quiet, the app is quick and responsive, and the battery life is excellent. Eufy insists that only its own cleaning solution is used with the mopping system, adding to the ongoing costs. It also sits in the premium price bracket –

Eufy took the unusual move of launching this robotic vacuum and mop as a crowd-funded Kickstarter project. It raised a whopping $3.5m from almost 3,200 backers at the time of writing, with many backers paying $999 for their S1 Pro. The actual retail price is significantly higher, at $1,499 / £1,499 (it's not currently available in Australia, but that's equivalent to AU$2,699) from when the vacuum robot went on sale on 19 June 2024.

Being a vacuum cleaner and mopping system, there are several parts that can be replaced over time. Eufy includes several spares in the box – more on which later – but buyers should bear in mind that they’ll need to pay for replacement dust bags, filters, mops and brushes when the included ones wear out. Eufy also insists S1 Pro owners buy the company’s own hard floor cleaner, which comes in a $19.99 bottle specifically shaped to fit the S1 Pro. Other cleaners, Eufy says, may cause 'irreversible damage' to the machine.

The idea of a four-figure vacuum might be shocking to some readers (and it does sit in TechRadar's premium price bracket), but it's not so unusual these days, at least when looking at flagship models. The Roomba Combo j9+ by iRobot costs a similar amount, while the Roborock S8 MaxV Ultra isn’t far off $2,000.

Eufy Omni S1 Pro review: design

• Self-emptying charge dock handles dust and water
• Rotating mop applies pressure and self-cleans as it goes
• 3.78-inch / 9.6cm tall

With the S1 Pro, Eufy has gone against the trend for robotic vacuums with smaller, more compact docking stations. Instead, this is a robot with a large, imposing base station that houses the dust bin, as well as tanks for clean and dirty water, and a cleaning solution.

The base station is 67 cm tall and has a footprint of 38 x 47cm. I was able to tuck it into a corner of my small flat for a few weeks to conduct this review, but had to move a table to make sure the base station had the required 50cm of clear space either side. It’ll function without this clearance, but the robot won’t be able to clean between its charger and the nearby wall.

The robot itself is broadly similar to most other automated vacuums, albeit slightly taller than the Roomba Combo J9 Plus. The Eufy measures 9.6cm tall, 32cm wide and 34cm long. Turn it over and you’ll find a pair of heavy-duty wheels, a 290 mm rotating mop, a pair of spinning brushes for clearing dust and debris from the corners of your floor, and a rubber roller brush for scooping dust and debris into the suction system. This is all easily accessible without tools, by simply removing the top cover (which is held in place magnetically) then lifting out the robot’s dust bin.

Handily, the robot speaks aloud when items have been removed and installed. It’ll say things like 'dirty water tank removed' and 'dust bin installed' to help you quickly identify each component.

The charge base has a control panel on the top, complete with buttons for operating the robot and a display that shows animations to help with maintenance, such as how to replace the water tanks. It also says when filters and other components need cleaning. This means you can use the robot without even touching the smartphone app (once it has been set up, anyway). Printed instructions make the setup process very simple, and you’ll be up and running in just a few minutes.

The S1 Pro's design means it empties its dust bin into a larger bag in the base station at the end of each cleaning session. It also fills its onboard tank with clean, ozonated water from the base station’s larger tank before each session, then empties itself into the base’s dirty water tank when finished. Eufy says the dust bag should only need replacing every couple of months, while the water tank managed half a dozen mopping sessions before running dry. Naturally, this will depend on your floor space and how much is mopped.

I was impressed with the quality of the Eufy’s hardware. It all feels very sturdy, but takes up plenty of space. I would have liked to see storage space in the dock for spare parts, as with the iRobot Roomba Combo J9 Plus, but that isn't the case here. To its credit, Eufy suggests the taller base station makes it easy to pick up and replace the water tanks, since smaller base stations mean stooping over.

Lastly, there's no option to plumb the base station into your home’s water supply, but Eufy says 'water accessories' for the S1 Pro are currently under development.

Eufy Omni S1 Pro review: performance

• Superb mopping abilities
• Solid navigation capabilities, but could fail to spot even larger debris
• Vacuuming is good but not great

As with any robot vacuum, its first task was to map my apartment. Our property has a lounge, hallway, kitchen and bedroom, plus a bathroom with a step, so the robot has access to every corner of the property, except for part of the bathroom. If I wanted to map that small section, I could have, since the app lets you save maps of multiple floors.

The S1 Pro quickly plowed into a relatively thick rug and got stuck, before calling for help. My bad. I’d not reviewed a robotic vacuum in this property before and, while the style of rug isn’t uncommon, it’s a little higher than the 25mm maximum carpet height Eufy says the S1 Pro can cope with.

Lesson learnt, rug rolled up and robot restarted, it quickly mapped the entire flat and returned to base, having not slipped down the bathroom step.

The Eufy Clean app now shows a very accurate map of my home, and it takes just a few seconds to separate the rooms into different zones and give them each a name. That way, you can tell the robot to go clean one room, or vacuum all rooms but one.

Eufy claims 8,000 Pa of suction power, which is the same as some of the brand’s cheaper robotic vacuums, like the Eufy X10. There are four suction levels to pick from, called Quiet, Standard, Turbo and Max, plus mopping settings of Soft, Standard and Deep, and the option to clean an area once or twice in each session.

You can also tell the robot to vacuum and mop an area, or just vacuum – since you won’t want it to mop your carpets. And on that note, the robot automatically detects carpet, then lifts the mop to keep it clear of the floor. There’s no option to mop only, so it shouldn’t be used to clear up large liquid spills, since it’ll try to vacuum the floor first.

Before giving the S1 Pro a set of specific challenges, I used it for a week as a normal robotic vacuum and mop. I found it very easy to use and the mopping results were fantastic. It really does a great job of cleaning wooden floors, administering just the right amount of water to not leave puddles or streaks, and cleaning the mop as it goes. Eufy says the mopping roller spins at 170 rpm and pushes down onto the floor with a force of 2.2lbs.

My varnished floors shone clean and, if more proof were needed, the murky contents of the waste water tank looked like it had been scooped out of the River Thames.

After vacuuming and mopping, the S1 Pro returns to its charger and empties its dust bin and water tank, then dries the mop. The emptying takes just a few seconds (but is rather loud, peaking at 79dB, compared to just 62dB when vacuuming on the quietest mode and 76dB on max suction), then the mop is cleaned and dried over a period of about 4.5 hours. There’s a quiet humming during this time, but at just 50dB it isn’t really noticeable.

As for intelligence, the S1 Pro’s ability to drive around obstacles is good. It uses what Eufy calls its 3D MatrixEye Depth Perception System to understand its environment. This comprises a camera with a 120-degree lens and a lidar system. I found the Eufy does a great job of driving close to walls and furniture while very rarely crashing into anything. It even uses a set of icons on the map to indicate where it has avoided some common items, like shoes and cables.

Moving to more specific tests, and the results were mixed. First up, I tested the S1 Pro on a mix of biscuit crumbs and flour. It had no trouble picking this up from a hard floor, even with the lowest and quietest suction mode, but had a habit of flicking debris into the corners of the room with its spinning brushes, which it then failed to collect. It also struggled to clear a floor threshold strip that had previously caused it no problems; I noticed how the robot tried a few times to drive over it, then drove more quickly and succeeded.

I repeated this test on carpet but the higher Turbo and Max suction settings were needed, and even then some of the flour and crumb mix was left behind.

During these tests the robot sometimes failed to enter one room. There’s a small, ~2cm threshold to clear between the wooden hallway and carpeted bedroom, and the Eufy managed this just fine on numerous previous cleans, but failed on this occasion, before succeeding on a subsequent clean.

I later learnt this hesitancy is solved by digging into the settings pages of the Eufy Clean app and disabling a function called Visual Anti-Drop. After that, the robot drove over thresholds with more confidence.Pictured below, this must be right on the threshold, so to speak, of what it’s capable of clearing.

I expected a little more from its vacuuming abilities during this test, and was left with the impression that, while good at performing a daily clean of an otherwise tidy home, the S1 Pro can’t be relied upon to clean a specific area of dirt, or a recent spill of food or other debris. I instead reached for my Dyson V10 and had the carpet spotless in just a few seconds.

Next up, I tasked the Eufy with clearing larger dry debris from the same wooden floor and carpet as the previous test. For this I used oats, and thankfully the Standard mode was enough to pick up almost every single piece from a wooden floor. The rotary brushes still flung some dirt into the corners, but it was mostly a success.

It performed similarly well on carpet, with most of the oats picked up and just a few left behind. Frustratingly, the robot declared the clean complete and shut down the vacuum with a bunch of oats right in front of it.

The large oats also highlighted a problem with the S1 Pro’s self-emptying system. It appeared to have done everything correctly, but when I picked it up a couple of hours later a load of oats, dust and fluff fell out from under the robot. I couldn’t see an obvious blockage and the dust bag in the base station was only around 20 percent full, but contained only half the oats it should have. The rest were caught up in the rotor, having not made it to the bin, and fell out.

I’ve now realized you need to set the robot to empty its dustbin every time it returns to the charger (an option in the app), instead of less frequently. Otherwise, debris will spill out when you pick it up, for example to move it to a different floor.

All that said, I need to reiterate just how good the mop function is, and how thoroughly it cleans both the floor and itself. I hope a future software update will suggest owners turn off the Visual Anti-Drop function if the robot struggles with thresholds.

Finally, the battery life seems very good indeed. On one particular clean, the charge level fell from 100 percent to 94 percent after 22 minutes of vacuuming an area of 140 square feet. Eufy says the robot can run for 3.6 hours and cover a space of up to 1,976 square feet on one charge.

Eufy Omni S1 Pro review: app

• Easy to set up and use
• Can schedule cleans and target individual rooms
• Offers lots of configurability

The Eufy Clean app is impressive and makes it easy to control the vacuum, create schedules and split your home into zones. The latter works especially well, with the robot quickly mapping our flat and correctly splitting up the rooms and hallway. Once that’s done, it’s easy to tell the robot to clean an individual room, or draw a box over a specific area that needs vacuuming or mopping.

The app gives access to all four suction modes, both mopping modes, and lets you tell the robot how you’d like each room cleaning. For example, you could ask it to do an extra thorough job of the kitchen and hallway, while going easy on the spare bedroom. There are lots of settings to fiddle with, but it’s all intuitively laid out and neatly explained. The app is also used to create virtual walls and set up no-go zones to stop the robot entering certain areas of your home.

How I tested the Eufy S1 Pro

I lived with the S1 Pro for a few weeks before writing this review. I let it map my home, then used it to keep on top of the vacuuming and mopping, leaving to clean every room on the standard setting every few days. After this, I carried out several specific tests to see how well it picks up different types of dry debris from both hard floors and carpet.

I observed how the robot navigated, how it avoided objects and steps, and how it managed with raised thresholds. I also kept tabs on battery usage and used an app to test how loud it is in all of its various cleaning modes.
