The Dyson Spot+Scrub Ai Excels as a Robot Vacuum – But Leaves the Mopping to the Humans

The Spot+Scrub Ai marks a shift for Dyson as its first robot vacuum to combine suction with a built-in mop. It's also the first real attempt at the wet-and-dry category dominated by rivals for years.

When it comes to vacuuming, particularly on carpet and pet hair, it's a strong contender for one of the best robot vacuums I've tried. When it comes to mopping, it falls short.

At $1,199, this isn't a cheap appliance, and after four weeks of testing, I found the Spot+Scrub Ai does most of what Dyson promises, just not all of it. Read on to find out where it excels, and where it let me down.

The One-Minute Summary

Dyson's first entry into the best vacuum-mops category combines serious vacuuming credentials with a disappointing mop.

Across four weeks of testing with a dog and children in the house, it cut my manual vacuuming by more than 90%, the biggest reduction I've seen from any robot vacuum I've tested. Its carpet and pet hair performance consistently impressed me more than my own upright Dyson, and its see-through dustbin reinforces that, regularly revealing just how much debris and hair it's pulling out of carpets I thought were already clean.

In standardized testing, the Spot+Scrub Ai handled sugar and lentils cleanly, but treated scattered cereal as an obstacle rather than mess, working through it in a stop-start pattern that often left pieces behind. It's a similar story with mopping, where ketchup cleared well, mustard was simply smeared around, and a foam trail left by the wet roller would occasionally trigger the robot into a repeated stain-removal loop until it gave up entirely. Over several weeks, I found myself mopping manually more often than I'd like.

The dock handles roller washing and bin emptying automatically, though the bin's release mechanism isn't obvious without checking a video first. If you're after the best robot vacuum for vacuuming and pet hair, this is one of the strongest I've tested. If mopping matters just as much, the Dreame Aqua 10 Roller remains the more dependable all-rounder, and it's the robot vacuum I always come back to at home when I'm not testing anything else.

Dyson Spot+Scrub Ai: Setup

Getting the Dyson Spot+Scrub Ai up and running took a little longer than most robot vacuums I've tested, but that's not a huge surprise for a model with this many moving parts. Inside the box is the robot itself, the docking station, and a docking ramp. The two side sweepers (one red, one blue) and charging cable are in a separate tray, and all of it is packaged neatly and in easy-to-recycle packaging.

The docking ramp clicks onto the front of the station, and the charging cable connects at the back, at which point an LED confirms it's live. This LED was flashing red for a long time, and I wasn't sure what the error was until I filled the clean water tank, at which point it turned white.

To fill this tank, lift it out using its handle, lift the blue rubber flap on the back of the dock, and pour in your floor cleaner. Dyson recommends only using its own 02 Probiotic hard floor cleaning solution, but it doesn't include a bottle in the box, which means spending another $23.99 on top of what is already an expensive robot vacuum.

You can, in theory, use any hard floor cleaning solution or even skip this step completely, but this can cause problems with excess foaming – as I explain more about in the Performance section – and could invalidate your warranty. Once the solution is added, unclip the tank's lid and top it up with clean water before slotting it back into place.

Attaching the side sweepers is the easiest part of the process: turn the robot over on a soft surface, and click the red sweeper into the left mount and the blue one into the right.

Once assembled and positioned, the smart home setup via the MyDyson app is quick and easy. With the robot placed on the dock, the app walks you through connection, and you confirm the pairing by pressing the Power and Home buttons on the robot.

The robot then does a mapping run. Mine created a decent first map in a little under 15 minutes – although it thought my garden was an extra room. Obstacles, furniture, and room boundaries were identified, and the robot was then ready to start deep cleaning my home.

The app recommends charging the robot to 100% before running the initial deep clean, although mine managed it on 52% (the level of battery it had straight out of the box). The dock then takes care of all the prep, including washing the roller mop. All you need to do is clear the floor.

In my test, this initial setup took around 25 minutes, including water tank filling and the first mapping run. This puts it on par with the Dreame Aqua 10 Roller, which I found similarly quick to map but more fiddly to assemble.

Dyson Spot+Scrub Ai: Design and Features

The Spot+Scrub Ai is unmistakably and unapologetically a Dyson, complete with its red, purple, and gray colour scheme running throughout.

The dock is matte gray with a large, see-through dustbin on the left that has Dyson's iconic purple plastic lid with red clips and buttons. Next to this dustbin are two cylinders: one with a small, filled purple circle on the top (clean tank, right-hand side) and one with an outline of a circle (dirty tank, center).

It's not immediately clear which is the clean tank and which is the dirty water reservoir, and even now, after a month of testing, I occasionally forget and have to remove each to see which has the cleaning solution port behind it, and is therefore the clean tank.

Below the tanks are the two charging ports and the textured ramp where the robot sits when it's charging.

The charging cable that comes with the dock isn't very long, which limited where in my kitchen I could set it up so it was close enough to a plug but not in the way. Dyson's manual recommends putting the dock against a wall, on a level surface, with at least 19.7 inches of clearance around the sides and a staggering 59 inches in front, which narrows down suitable locations even more.

As does the fact that this isn't a unit you can tuck unobtrusively into a corner; at 17.9 inches high, 17.3 inches wide, and 20 inches deep, it has a large physical footprint, and I'd recommend checking the space in your own kitchen or boot room before committing.

As a side note, 59 inches is almost 5 ft, and for a lot of kitchens that will be impossible. I positioned mine in a much smaller area, and it had ample space to move around.

The robot itself is a round disc made of matte black plastic. Power and Home buttons sit on the top, and a status light between the buttons pulses white when charging and turns amber if something is wrong.

Just behind these buttons is a hinged panel marked Filter, where you'll find the removable built-in dustbin and filter. To access this bin and filter, you need to push the bottom of the robot up to release the latch. This isn't immediately clear and can be fiddly.

Flip the robot over, and you'll see the wet roller on the front half, which consists of a horizontal blue microfiber cylinder. The two side sweepers, which are used for pulling trapped debris from corners and edges sit above it.

Behind the wet roller is the anti-tangle brush bar, a shorter red-bristled roller beneath a hinged cover with a red release tab, two large treaded wheels and a camera and sensor cluster is built into the front.

According to Dyson, the wet roller uses a "12-point hydration system" that refreshes the roller with heated water on every rotation rather than dragging a single damp pad around the floor. It also extends to both the left and right as and when needed for better baseboard cleaning.

A camera and sensor cluster is built into the front edge, and this is where the Spot+Scrub Ai's stain-detection system lives. This system beams a blade of green light over the floor to spot and catch dust, crumbs, and stains that can sometimes be missed in normal lighting.

On carpet, for example, the AI lifts the wet roller out of the way to avoid spreading stains, while the dry brush bar retracts when it senses liquid, so wet messes don't dirty the roller.

The HD camera then sits just above this light strip, sending what the light sees to an onboard AI processor that compares the image against a reference bank of nearly 200 different substances, from food and liquid to pet mess and hidden dust.

This AI decides how the robot should respond, and all of this happens locally on the robot itself rather than in the cloud, which Dyson positions as a privacy benefit as much as a speed one.

The dock then handles everything else. Its cyclonic system empties the robot's bin, while the wet roller is washed in 60°C water and dried with 45°C warm air, ready for the next cycle without you touching it.

All of this runs through the MyDyson app, which – if you've used any smart Dyson product before – will be instantly recognisable and is where all of your Dyson appliances and tools live.

If you haven't used the app before, it has a black background with white text and icons. The home screen shows a 3D render of the robot and dock, sitting above a navigation bar split into Overview, Manage maps, and Product settings tabs. From Overview, you get a live status showing battery percentage, current activity (washing or drying the wet roller), and an Activity history screen where you can check previous cleans.

The Manage maps tab is where the floor plan lives, and tapping into a clean brings up a "Set up clean" screen with two toggles at the top: Room and Target. This lets you either select specific rooms or draw a target zone for one-off cleans.

For the cleans themselves, you can switch between Auto, Quick, Quiet, and Boost cleaning modes, choose vacuum-only, wash-only, vacuum-then-wash or even adjust hydration level, plus create cleaning schedules. It's a similar level of control to the Dreame Aqua 10 Roller and is one of the best parts of the Spot+Scrub Ai in my opinion.

Maintenance features are built into the app too. You can check the condition of brushes, filters, and bags, see when parts need replacing, and order spares directly. Plus, it's a good place to start if your robot vacuum keeps getting stuck or isn't working as it should.

What Is the Dyson Spot+Scrub Ai Like to Use?

Living with the Spot+Scrub Ai is mostly hands-off, which is the point of a robot in this category, but the app takes longer to get used to than the interface suggests.

The basics are easy, but where it often slowed me down was room identification. The dark background and white labelling look sharp, but the room icons on the map aren't always easy to tell apart, and working out which numbered room matched which actual space in my home took some trial and error. Zooming and panning around the 3D map view is also less smooth than the flat 2D view, which I found easier to read during a clean.

The robot moves with the deliberate pace I'd expect from a LiDAR-equipped robot – it knows where it is and easily moves around and avoids furniture legs, shoes, and messy cables left on the floor. It also moves well over the thresholds between rooms.

I have a high threshold between the Karndean flooring in my kitchen and the solid wood of my hallway and the Spot+Scrub Ai didn't once hesitate or get tripped up by this in the same way other robots – even robots that cost a similar amount – have in the past.

Where the AI navigation is less convincing is how it interprets what it finds. You can visibly see the robot reacting to mess and on the most part, this is impressive. The Spot+Scrub Ai can return to areas time and again until it's successfully cleared the mess.

However, there were several occasions where I watched it treat larger debris as obstacles, rather than mess. It would approach, pick up a piece, divert, approach again, pick up another, divert again, rather than running a few passes over the whole area the way it does with finer debris. It would then effectively give up and say 'clean complete,' which meant I had to finish the job manually.

Finally, onto noise. When I first started using the Spot+Scrub Ai, it rattled and was annoyingly loud until I realised the cover on the dry brush compartment hadn't been locked into place properly, after which it was near-on silent during cleans.

The only time its noise felt intrusive was at the end of cleans when the dock automatically emptied the dustbin. It also makes a low hum when it cleans the mop, and that hum lasts for a few hours as the dock dries the mop too, but neither is a problem, and you soon get used to it.

Dyson Spot+Scrub Ai: Vacuuming Tests

To assess how well the Spot+Scrub Ai handles different types of mess, I ran a set of standardized tests on both hard floor and carpet, scattering a quarter cup each of sugar, lentils, and cereal across the floor with some pushed into corners and edges.

Sugar is used as a stand-in for fine debris like dust, lentils are a good proxy for medium debris, and cereal represents larger crumbs, kibble, or similar.

Sugar and lentils were handled well on both surfaces. The Spot+Scrub AI lifted around 95% of the remnants cleanly in a single pass without scattering further across the floor and picked up the rest on a second pass.

I was consistently impressed, both during these fine and medium debris tests and in day-to-day use, by how much was picked up and emptied into the dock each time.

Having the see-through bin helps with this, and it regularly highlights just how dirty my floor can be (even when it's recently been manually vacuumed), and just how much the Dyson Spot+Scrub Ai collects.

The standout performance and depth of cleaning, on carpet particularly, also makes the Spot+Scrub Ai a fantastic robot vacuum for pet hair.

Not only could I see just how many hairs had been collected on each run thanks to the see-through dustbin again, but even while building Lego, playing chess or sitting on the floor with my dog, I noticed far fewer dog hairs ending up on my hands, the board or the pieces. This was more impressive than my upright Dyson and gave me huge confidence about how clean my floors were with the Spot+Scrub Ai.

Even areas my dog tends to settle in, which usually need a manual vacuum to remove the dander once a day, stayed visibly clearer for longer than I'm used to.

Sadly, this performance set my expectations so high that when the Dyson performed so poorly with large debris, it made it all the more disappointing.

Rather than clearing the scattered cereal pieces in a few passes – or at all in some cases – the robot seemed to treat them more like obstacles than mess. When used in Room mode, the vacuum worked relatively methodically and was able to capture most of the large debris other than pieces at the edges of rooms and furniture. It wasn't perfect, and it didn't live up to its performance with fine and medium debris, but it was passable.

In Target mode however, when cleaning hardwood floors as well as carpet, the Spot+Scrub Ai consistently failed at the most basic of tasks.

It would often approach a piece of debris, recoil slightly as if it was an obstacle, go back to it, pick it up, divert slightly, approach the next piece, bounce away from it, return to pick it up, divert again and repeat.

It worked in a stop-start pattern rather than running a clean sweep over the area, and this meant that sometimes it cleared the lot, but at other times it only cleared small pockets of debris. It would then announce it had finished and return to the dock, leaving me to finish the job myself again with a manual sweep or vacuum.

In practical terms, and for most day-to-day messes and general upkeep of the house, I can hardly fault the vacuuming prowess of the Dyson Spot+Scrub Ai. It cut my manual vacuuming by in excess of 90% – the biggest reduction I've seen in all my time testing robot vacuums. I still used my cordless vacuum on carpets and stairs every weekend, but for daily maintenance, the robot handled most of the work.

I rarely have spills that involve large debris, so beyond the standardized tests, its poor cereal performance didn't make a noticeable impact on my everyday life. It's most definitely worth noting and is a significant flaw in an otherwise brilliant vacuum, but it didn't end up being a dealbreaker.

Dyson Spot+Scrub Ai: Mopping Tests

As the first Dyson robot vacuum to come with a mop, a feature that was missing from its predecessor, the Dyson 360 Vis Nav, I was most excited to see if Dyson's vacuuming expertise could expand to mopping. Sadly, it didn't.

I tested its mopping skills using our standard two-stains method. For the first test, I poured a quarter cup of ketchup onto my kitchen floor; for the second, I used a quarter cup of mustard.

The ketchup, which is slightly thinner, was cleared reasonably well. The mop lifted it within a couple of passes without much residue left behind.

Mustard, being thicker, didn't fare nearly as well.

The robot moved over it repeatedly but largely just spread it around rather than lifting it away. Similar to how it handled the large debris, the vacuum incorrectly concluded it had finished, even when there were still large blobs of mustard on the floor. It scanned the area, announced it was done, and returned to the dock.

After both tests, the floor felt sticky rather than clean, and even when my husband returned home three hours later, he said he could still smell ketchup.

The issues didn't stop there, though. The wet roller would leave trails of foam, evenly spaced, behind it as it worked. Unless caught early, these trails would dry and become water marks, and you could visually see the route the Spot+Scrub Ai had taken.

On the odd occasion, the stain-detection system that makes the robot so attentive to spills also made it overly sensitive to problems like the foam trails. It kept reading each foam trail as a fresh stain; it would then spin back around to deal with it, which would leave more foam behind it, which it would read as a stain, and it got stuck in a stain removal loop to the point I had to send it back to the dock manually.

On one hand, this may be my fault for not using Dyson's own solution. On the other, it's poor form that you're forced to spend more on a very specific product to not have to suffer poor performance. Plus, I've never had this problem using my own solution with any other robot vacuum-mop I've tested, so it's hugely disappointing.

After mopping, floors were left slightly damp but not soaked on the default hydration settings, but you can increase or reduce how much water is used in the app. In most cases, they were dry enough to walk on comfortably within five minutes, albeit a bit sticky.

Over several weeks of testing, I found myself actively avoiding using the mopping feature on the Dyson and mopping manually more often, which is far from ideal.

Dyson Spot+Scrub Ai: Maintenance

One of the main reasons to buy a robot vacuum is to cut down on day-to-day chores rather than add to them, and the Spot+Scrub Ai is a mixed result on that front.

Most routine maintenance is meant to be handled by the dock. After each run, it empties the dustbin, washes the wet roller to stop odor and dries it with warm air automatically. During my tests, the roller always came out clean and dry and never damp or musty.

Hair management is also good, helped by the anti-tangle design on the main brush bar. With a dog in the house and my long hair, I still needed to check the brush bar every couple of weeks and pull out the odd wrapped strand by hand, rather than never touching it at all but it was minimal.

Day-to-day, the clean and dirty water tanks are easy to lift out and refill, but the dustbin itself is trickier, and I had to watch a video to work out how to empty it – it's very easy once you know how, but it's not immediately obvious.

The bin and filter assembly pops up from a hinged panel on top of the robot with a gentle press, and both the robot's filter and the docking station's filter can be rinsed under a tap and left to dry for 24 hours before refitting. The wet roller and brush bar slide out in a similar way, each released by a button or tab rather than anything more involved.

Dyson recommends washing filters monthly and replacing the water filter in the dock annually, and the MyDyson app doesn't yet flag these reminders automatically in the way some rival robot vacuums do, so it's on you to keep track in the Product Settings menu.

It does, however, let you order replacement parts from the app, and because knowing how to clean a robot vacuum is key to extending its lifespan, this is a welcome touch.

Overall, maintenance sits somewhere between hands-off and hands-on. Topping up water, emptying the dirty tank, and the occasional hair check are unavoidable, but the dock does handle the bulk of the day-to-day work without intervention. For a robot at this price, that's about what I'd expect, even if it isn't quite as effortless as the most hands-off robots on the market.

How Does the Dyson Spot+Scrub Ai Compare?

Against the eufy Omni S1 Pro, our current favorite robot vacuum, the Spot+Scrub Ai's biggest advantage is its dock, which stores debris for up to 100 days versus the eufy's 60. That means longer stretches between having to manually empty the bin. The eufy edges it on overall vacuuming and mopping consistency, though, and fewer of the stain-detection quirks I encountered.

The Roborock Saros Z70 sits at a similar level but takes a different approach, using a mechanical arm to physically pick up socks, tissues, and other small objects from the floor. It's a novel answer to a problem the Spot+Scrub Ai still hasn't solved, given how it treated cereal more like an obstacle than a mess during my tests.

For a more direct mop comparison, the Dreame Aqua 10 Roller offers stronger suction on paper at 30,000 Pa against the Dyson's 18,000 Pa, along with a longer-running self-cleaning system that I found much more dependable on tougher stains. The Dreame Aqua 10 Roller is my go-to robot vacuum at home when I'm not reviewing alternative models, which says a lot about how highly I rate it.

Alternatively, if budget is the priority, the Shark PowerDetect 2-in-1 costs less but still offers a capable clean across both vacuuming and mopping. It doesn't match the Spot+Scrub Ai's hair pickup on carpet, but for homes without pets that gap may not justify Dyson's premium.

How I Tested the Dyson Spot+Scrub Ai

I used the Spot+Scrub Ai as my main robot vacuum for four weeks, running it across hard flooring and carpet, with a dog, children, and the usual day-to-day mess that comes with both.

Alongside daily cleans, I ran our standardized vacuum tests, scattering a quarter cup each of sugar, lentils, and cereal on both hard floor and carpet to assess fine, medium, and large debris pickup, and setting two stains, ketchup and mustard, on hard flooring to test the mopping function.

I tracked how the robot navigated my home, how it handled the dock's self-cleaning and self-emptying cycles, and how the MyDyson app held up across day-to-day scheduling, room management, and cleaning history.
