Best Robot Vacuums 2026: 6 Models Tested and Reviewed
The best robot vacuum of 2026 for most homes is the iRobot Roomba 205 DustCompactor Combo: it vacuums and mops in one pass, compacts the dirt inside the robot, so in our test it went two months without being emptied, and it covered our 90 m² three-room circuit, two rugs included, on a single charge. If mopping is your priority, the Roomba Plus 405 Combo adds a dock that washes and dries its spinning mop pads. We have analysed 34 models in Spain, and these 6, all available on Amazon.co.uk, made the cut.
The best robot vacuum for every situation
- Best overall: iRobot Roomba 205 DustCompactor Combo. No bulky dock, two months without emptying in our test and a full three-room circuit without recharging.
- Best for hands-free mopping: iRobot Roomba Plus 405 Combo. Spinning mop pads that turn at 200 rpm and press down hard, and a dock that washes and dries them.
- Best for pet hair and cluttered floors: Xiaomi Robot Vacuum 5 Pro. 20,000 Pa, a blade that cuts hair on the main brush and three AI cameras that recognise more than 200 objects.

Pros
| Compacts the dirt, so you only empty it about once every 60 days. | Spinning mop pads at 200 rpm with downward pressure lift dried stains easily. | 20,000 Pa of suction that picks up every bit of dust and hair. | 98.0% average pick-up across hard floor and rug, the highest we've measured. | Station washes and dries the mop pads and empties the dust, with 4.5 L and 4.0 L tanks. | 10,000 Pa of suction, ideal for pet hair, fine dust and deep-cleaning rugs. |
| Precise, methodical laser navigation. | Detects rugs and lifts the mop pads automatically so they stay dry. | Vibrating mop pads with 80 °C hot water for a deeper clean. | Crosses stepped thresholds of up to 8.6 cm in total. | 10.5 mm mop lift and rug detection, so short pile stays dry. | Vibrating mop pads that mimic hand scrubbing and shift stuck-on stains. |
| Intuitive app for scheduling cleaning by room, day and time. | Station that washes, dries and empties the robot with no hands-on work. | Station that washes, dries and empties itself with no hands-on work. | Returns to the dock with 58% battery after a three-room circuit. | Double extending arm brings the brush and mop right up to the skirting board. | Self-emptying station with a bag you only change every couple of months. |
| Detects rugs and raises its suction automatically. | Laser and front-camera navigation that avoids cables and socks. | AI recognises over 200 objects and your pets to avoid collisions. | Only 7.98 cm tall, so it fits under low sofas and beds. | Maps up to 4 floor plans and resumes after recharging. | Lifts its mop pads 8 mm when it detects a rug so it stays dry. |
Cons
| On our test unit it didn't avoid rugs when mopping unless you marked them in the app. | The app doesn't show the water level or mop pad wear, so you have to check by hand. | The station takes up more space than usual (57.2 cm tall x 36 cm deep). | Leaves a faint shadow of dried tomato on laminate after two passes. | Sticky dried stains such as tomato need two passes and can leave a faint ring. | Slows down on long-pile rugs and doesn't clean them as thoroughly. |
| The app doesn't show the water level, so you have to check it on the robot. | The station takes up quite a lot of room, so plan where it goes. | It needs a dedicated spot in your home. | 1.0 g of fine flour left in the rug; the chassis doesn't lift on short pile. | Suction delivers a little less on rugs and leaves fine flour at the base of the fibres. | Mop pads and filters have to be washed by hand. |
How we test robot vacuums
For this comparison we have analysed 34 robot vacuums, and these 6, all available on Amazon.co.uk, are the ones that made the cut. All our tests took place in Spain, with the same models you can buy in the UK. Every robot ran the same circuit (living room, hallway and bedroom with two rugs) over hard floors (laminate and porcelain tiles) and short-pile carpet, and each unit ran at least until it had used a full charge and returned to its dock on its own.
The three tests that decide the score
- Suction power. 30 g of rice and flour spread over a 50 cm square on hard floor and on short-pile carpet, with a single pass on maximum power. Whatever is left is picked up afterwards with a handheld vacuum and weighed. The best result in this ranking is the Roborock Saros 20, which left 0.2 g of the 30 on hard floor and 1.0 g on carpet; the Dreame L10s Ultra Gen 3 left 0.4 g and 1.8 g.
- Battery life. Continuous cleaning of the circuit on medium power until the robot returns to its dock. We time it, note whether it finishes in one go or needs to recharge and, on models with mapping, how long it takes to resume where it left off; on gyroscope-navigation models we note that they cannot resume. The Saros 20 docked with 58% battery left after 72 minutes, the biggest margin we measured; the L10s Ultra Gen 3 needed 81 minutes and also finished without recharging.
- Mopping. Dried stains of milky coffee and tomato sauce on laminate and on tiles, left for 30 minutes. Two passes on medium water flow with whatever mopping system the robot uses, pad or roller; we check for rings once dry, how many centimetres are left unmopped along the skirting board (0.2 cm on the Saros 20 and 0.5 cm on the L10s Ultra Gen 3) and what it does with rugs: wets them, lifts its mops or steers round them.
Every rating in this guide is based on real-world tests, continued use and direct comparison between models, using the same protocol for all of them.
How we calculate the score
Each robot vacuum’s overall score is the simple arithmetic mean of three criteria, each rated independently out of 10:
- Suction power
- Battery life
- Mopping
These three criteria are exactly the sub-scores you’ll see broken down on each product page, so you can compare model by model against the same yardstick. There is no weighting: the overall score is the average of the three, in equal parts.

The best robot vacuums: our tested ranking
1. Roomba 205 DustCompactor Combo: the best robot vacuum overall
Test results
- Suction with 30 g of rice and flour: almost nothing left on hard floor and a short-pile rug far cleaner than we expected after one pass; it raised suction on the rug by itself
- Three-room circuit battery life: about 90 m² covered, two rugs included, without recharging, bumping into things or getting lost
- Dried coffee and tomato mopping: no rings or puddles on laminate or tiles; the coffee lifted easily, the tomato took more effort
- Emptying: two months of normal use before the compacted dirt had to be emptied
Why we recommend it
It's the robot that asks the least of you. iRobot compacts the dirt inside the robot itself, so there's no bulky dock in the corner, and in our test we didn't have to empty it for two months of normal use.
It covered our living room, hallway and bedroom circuit, around 90 m² with two rugs, in a single charge, without bumping into furniture or losing its way. On the rug it raised its suction on its own, and the rubber main brush and the side brush left the grain far cleaner than we expected.
It vacuums and mops in the same pass, with steady pressure that lifted the dried coffee and left no rings or puddles on laminate or tiles. Its 240 ml tank comfortably lasted both mopping passes.
Weak points
At 9.3 cm tall it can’t get under some very low sofas and beds, so those spots stay off its route.
Dried tomato was harder work: it doesn’t gauge how dirty a spot is, so it won’t go back over a stubborn mark by itself. In our mopping test we also marked the rugs in the app beforehand, because in that mode it didn’t avoid them on its own, and the water level can only be checked on the robot, not in the app.
Who it's for
👤 If you want floors vacuumed and mopped every day without a big dock taking up space, and you'd rather forget about emptying the bin for weeks, this is your robot.
Biggest advantage
✅ It compacts the dirt inside the robot, so in our test it went two months without needing to be emptied.
Biggest drawback
❌ At 9.3 cm tall, it can't reach under very low sofas and beds.

2. Roomba Plus 405 Combo: best for hands-free mopping
Test results
- Suction with 30 g of rice and flour: no trace left on hard floor; on the short-pile rug it boosted suction by itself and also picked up tangled dog hair without clogging the brush
- Three-room circuit battery life: finished in one go without returning to the dock, and it cleaned a 150 m² space without running out
- Dried coffee and tomato mopping: no rings on tiles and no pad marks on laminate; the tomato needed several passes
- Rugs while mopping: lifted its mop pads before reaching the rug, which stayed completely dry
Why we recommend it
If mopping is what you want to forget about, this is the Roomba to go for. Its spinning mop pads turn at 200 rpm and press down hard, so the dried tomato that resisted at first came up completely after a few passes, with no rings on tiles and no pad marks on laminate.
Compared with the Roomba 205 above, it adds a dock that empties the bin, washes and dries the mop pads and only needs your attention every 75 days or so. When it spots a rug it lifts the pads and boosts suction, and the rubber anti-tangle brush pulled dog hair out of the fibres without wrapping.
On Amazon.co.uk it's listed as the Roomba 405 Combo with AutoWash Dock and sold by a third-party seller, Atlantic Electrics; it's the same model and the same Amazon listing we checked for the Spanish edition.
Weak points
The dock takes up a fair amount of room, so you’ll need to think about where it goes before it arrives.
The app doesn’t show the water level or mop pad wear, so you have to check both by hand, and if you leave out new objects it hasn’t seen before it can occasionally get stuck.
Who it's for
👤 If you want a robot that vacuums and mops a medium or large home and then looks after its own mop pads, and you have room for a bigger dock, this is the one.
Biggest advantage
✅ The dock empties the robot and washes and dries the spinning mop pads, with manual upkeep only every 75 days or so.
Biggest drawback
❌ The app shows neither the water level nor the state of the mop pads, so you have to check them yourself.

3. Xiaomi Robot Vacuum 5 Pro: best for pet hair and cluttered floors
Test results
- Suction with 30 g of rice and flour: no manual touch-ups needed on hard floor or short-pile carpet; the handheld vacuum barely found any flour in the rug fibres
- Main brush after the pass: still spinning freely, with the built-in blade cutting long hairs instead of letting them wrap
- Three-room circuit battery life: completed in one go, with no need to step in or restart the cycle
- Dried coffee and tomato mopping: no visible rings on tiles or laminate once dry, and it lifted its mops 1.8 mm by the rug without wetting it
Why we recommend it
It has the highest suction score in this ranking, and you can see why on carpet: as soon as it moved from tiles onto the rug it went to full power, and the handheld vacuum we ran behind it barely found any flour left in the fibres. With its 20,000 Pa there was no need for manual touch-ups on either floor.
What sets it apart for pet owners is the blade built into the main brush, which cuts long hairs instead of letting them wrap, so the brush was still spinning freely after the test. Its triple-camera AI system recognises more than 200 types of object, from socks to furniture, and even spots dogs and cats so it doesn't frighten them.
It mops with 80 °C hot water, which is what dissolved the dried tomato on our circuit without smearing it around, and the dock then washes the mops and dries them with hot air. On Amazon.co.uk it's sold by Amazon under the UK reference BHR07WEGB.
Weak points
Its dock is bigger than a standard one, at 57.2 cm tall and 36 cm deep, so it needs a dedicated spot in your home.
We don’t have a weighed residue figure or a timed lap to publish for it, so on paper it can’t be compared to the gram with the Saros 20 and the L10s Ultra Gen 3, even though it needed no touch-ups on our circuit.
Who it's for
👤 If you share your home with a dog or cat, the floor is rarely clear and you want the robot to cope on its own, this is the one to look at.
Biggest advantage
✅ 20,000 Pa of suction plus a blade that cuts hair on the main brush, so pet hair doesn't end up wrapped around it.
Biggest drawback
❌ The dock is 57.2 cm tall and 36 cm deep, larger than a conventional one.

4. Roborock Saros 20: best for thresholds and low furniture
Test results
- Suction with 30 g of rice and flour: 0.2 g left on hard floor and 1.0 g on short-pile carpet
- Three-room circuit battery life: 72 minutes, no recharge needed and 58% battery left when it docked
- Dried coffee and tomato mopping: three of the four stains with no ring and 0.2 cm left unmopped along the skirting board
- Single-step threshold: 4.3 cm cleared on all three attempts; at 4.6 cm it starts to fail
- Two-step threshold: 8.6 cm in total, cleared on all three attempts

Test results
- Suction with 30 g of rice and flour: 0.4 g left on hard floor and 1.8 g on short-pile carpet
- Three-room circuit battery life: 81 minutes, no recharge needed
- Dried coffee and tomato mopping: three of the four stains with no ring and 0.5 cm left unmopped along the skirting board

6. Roborock Q10 S5+: strong suction and sonic mopping for a smaller budget
Test results
- Suction with 30 g of rice and flour: no visible trace on hard floor or short-pile carpet; on a long-pile rug it slowed down and cleaned less deeply
- Brush after the pass: not a single pet hair wrapped around the double anti-tangle brush
- Three-room circuit battery life: completed without asking to recharge
- Dried coffee and tomato mopping: both stains gone with no ring on laminate or tiles, edges as clean as the centre
Why we recommend it
It brings features you'd expect higher up the range to a much more modest robot. Its 10,000 Pa of suction cleared the rice and flour on hard floor and short-pile carpet without a visible trace, and the double anti-tangle brush didn't wrap a single pet hair.
Its vibrating mops scrub rather than just drag water around, and on our circuit both dried stains came up with no ring on laminate or tiles. When it spots a rug it lifts the mops 8 mm and boosts suction automatically.
Compared with the Dreame above, you give up mop washing in the dock, but you keep self-emptying, LiDAR mapping and mop lifting. The UK listing quotes a 2.7 L dust bag that lasts up to 7 weeks between changes.
Weak points
On long-pile rugs it slows down and can’t lift what’s buried deep in the fibres as well as it does on short pile.
The mops and filters are washed by hand, and as it has no cameras it can brush against very thin chair legs or cables.
Who it's for
👤 If you mostly have hard floors, kids or pets at home and want self-emptying and real scrubbing without spending big, this is the sensible choice.
Biggest advantage
✅ 10,000 Pa of suction and vibrating mops that scrub off dried stains, with a self-emptying dock included.
Biggest drawback
❌ On long-pile rugs it slows down and doesn't clean as deeply.

Buying guide: how to choose the best robot vacuum
The first thing to look at isn’t suction power but how it navigates. That’s what separates a robot that cleans the whole house from one that wanders about bumping into things, and it’s also what changes most from one price tier to the next.
What each price tier gets you
The jump in quality isn’t spread evenly, so it’s worth knowing where you stand before you start comparing spec sheets.
- Entry level. Navigation by bump sensors and gyroscope. They don’t save a map and knock into chair legs and edges, although a bumper stops them doing any damage. They’ll do if your home is small, uncluttered and has no rugs.
- Mid-range. This is where LiDAR comes in, and with it maps, room-by-room cleaning and scheduling. They work well in low light and rarely bump into things, although carpet detection can miss thin, dark or fringed rugs. It’s the sensible tier if you have a pet and a bit of clutter; in our ranking, the Roborock Q10 S5+ shows how much a robot without cameras already offers.
- Premium. They add small-object detection and AI cameras, which is what really stops them getting stuck on cables and socks, although very thin objects still slip past them. Worth it if you have rugs and hard-to-reach areas and you’ll mop a lot. Obstacle avoidance isn’t one of the three tests behind our scores, so we don’t crown anyone here; what we have seen is that camera-and-AI models cope with an untidy room, like the Xiaomi Robot Vacuum 5 Pro, which recognises more than 200 types of object.
Suction power
This is where brands are improving most, with some Dreame robot vacuums already claiming 42,000 Pa. But the figure on its own doesn’t tell you much.
For smooth floors, almost any robot with 4,000 or 5,000 Pa will do if you run it every day. High suction really matters in two situations: rugs, especially long-pile ones, and pets. That’s where a weak robot leaves fine dirt between the fibres and forces you to go over it by hand.
Battery life and coverage
Mopping uses a lot of battery, especially if the robot makes several passes, so the minutes on the box fall short as soon as you use it in combined mode.
To give you an idea: in standard mode on hard floors, 150 minutes covers around 150 m² depending on obstacles. With mopping and two passes, coverage drops to around 75 m², and on maximum power to around 55 m². What really matters isn’t the maximum but whether it can recharge and resume, because then it heads back to the dock by itself and carries on where it left off.
Mopping and self-cleaning docks
Robots used to drag a mop around and spread more dirt than they removed. Now they return to the dock, where the mops are washed in hot water at 50-100 °C, wrung out and air-dried, and the dirty water goes into a separate tank.
There are three designs (rectangular pads, spinning round pads and rollers) and all three clean well, although the roller is the most effective on stuck-on stains. Pay attention to the pressure: basic models apply 6 N and the best reach 10 N, and from 8 N upwards mopping starts to cope with ground-in stains such as tomato, although on our circuit the two robots we measured to the millimetre, the Saros 20 and the L10s Ultra Gen 3, both left a faint tomato shadow on laminate. Lifting mops stop rugs getting wet and extending ones reach corners and skirting boards; a 1 cm lift falls short and it’s worth looking for 2 cm, and for long pile the only real solution is a robot that leaves its mops in the dock while it vacuums.
When it comes to the dock, tell apart self-emptying for dirt (2-3 L bags that give you two or three months without touching anything, usually found from the mid-range upwards) from liquid handling for mopping, with 2 to 4 litre tanks, which takes you into premium territory. The best edge mopping in our tests came from the Roborock Saros 20, which left just 0.2 cm unmopped along the skirting board, and the Dreame L10s Ultra Gen 3, with 0.5 cm thanks to its double extending arm.
Pet hair performance
With a dog or cat at home, what decides it isn’t suction power but the brush: rubber brushes or ones with a hair-cutting blade stop hair wrapping, while bristle brushes have you reaching for the scissors every couple of cleans. In this ranking, the Xiaomi Robot Vacuum 5 Pro cuts long hair with a blade on its main brush, the Saros 20’s split rubber-and-bristle brush finished our carpet test with a single loose hair, and the Q10 S5+’s double anti-tangle brush didn’t wrap a single pet hair. It’s the one criterion in this guide that really changes depending on the animal, so if you have pets, put it at the top of your list.
When isn't a robot vacuum worth it?
If you live in a small, uncluttered flat with no rugs and you vacuum every day, a cordless stick vacuum will give you a better result for less money, and without a dock taking up half a corner of the living room. The same goes if your home has stairs inside, because no domestic robot climbs stairs and you’ll end up carrying it yourself.
Nor is it worth it if what you’re after is retiring the mop for good. None of the robots we’ve tested removes a dried stain that’s several days old without leaving a trace, so if dirt gets ground into your kitchen floor, the robot will take care of the daily upkeep but not the deep clean.
Checklist: what to look for before you buy
- How much clearance is there under your furniture? Below 8 cm, only ultra-slim models fit.
- Where will the dock live? It needs a permanent spot near a plug socket, and full-service docks are around half a metre tall.
- Do you have rugs, and what kind of pile? If it’s long, check that it lifts its mops at least 2 cm or leaves them in the dock while vacuuming.
- Is there a pet at home? Look for a rubber or hair-cutting brush, never a bristle one.
- Will you run it at night? Make sure it has a quiet mode, and bear in mind that self-emptying is much louder than the robot cleaning.
- Which consumables does it use and how often do they need replacing? Bags, mops, filters and detergent are a recurring cost.
- Does the brand sell spare parts in the UK? That’s what decides whether your robot lasts five years or two.
- Is your router dual-band? Many models only connect to the 2.4 GHz network.

FAQs about robot vacuums
The questions we get asked most that the buying guide doesn’t already answer.
How long does a robot vacuum last?
The first thing to wear out is the battery, and with it the real battery life: from the third or fourth year it’s normal to notice it covers less floor per charge. The other parts (brushes, filter, mops) are consumables you replace without touching the robot itself. Before you buy, check that the brand sells spare parts in the UK, because that’s what decides whether the robot lasts five years or two.
Does it work in a house with several floors?
Yes, as long as it saves several maps: the Dreame L10s Ultra Gen 3 stores up to four floor plans, and, according to its UK listing, the Roborock Q10 S5+ also supports multi-level mapping. What no domestic robot does is climb stairs, so you’ll have to carry it up or down yourself and, if there’s only one dock, let it finish on the floor where it is. Gyroscope-navigation models don’t save a map and aren’t suitable for this.
How noisy is it?
In our measurements, a high-end robot vacuuming on maximum power sits at around 60 dB(A) at one metre, similar to a normal conversation. Watch out for the dock’s self-emptying cycle, which on one of the models we measured reached 69.8 dB(A) for a few seconds; on the Saros 20 and the L10s Ultra Gen 3 it was also clearly louder than the robot cleaning. If you’re going to run it at night, make sure it has a quiet mode and time-slot scheduling.
Do you need to tidy the floor before it runs?
It depends a lot on the navigation. Robots without object detection get caught on cables, socks and toys, so it’s worth clearing up first. Those with cameras and AI avoid most things: the Xiaomi Robot Vacuum 5 Pro recognises more than 200 types of object with its three cameras, and the Roomba Plus 405 Combo dodged furniture, chair legs and toys in our home without us having to tidy up. Models without cameras, such as the Roborock Q10 S5+, can still brush against very thin chair legs or cables.
What maintenance does it need?
With a self-emptying dock, the bag lasts between two and three months. The rest is routine: empty the dirty-water tank if it mops, clean the filter every few weeks and check the main brush for hair build-up, unless it has a hair-cutting blade like the Xiaomi Robot Vacuum 5 Pro, which cuts it by itself. Rubber brushes tangle far less than bristle ones.
Does it work without Wi-Fi or a phone?
They all start with the button on the robot itself and run a standard clean without a connection. Without the app you lose what really sets a modern robot apart: maps, room-by-room cleaning, no-go zones and scheduling. One detail to bear in mind if you have a dual-band router: many models only connect to 2.4 GHz Wi-Fi.
