Most guides to the best robot vacuums in the UK give you eight machines. This one gives you two, and the reason is the most useful thing on the page.
We went through every robot vacuum on Amazon UK with a visible star rating and checked one thing before anything else: can that rating be traced to the machine you would actually receive? In this category, usually not. Amazon lets a seller group different products under a single listing, and the star rating is then shared across all of them. The result is a 4.5 from three and a half thousand reviews that covers four current models and two machines discontinued seven years ago.
Once you strip those out, only three machines outside Roborock have more than a thousand reviews attached to the specific model being sold. One of those three has an after-sales record we could not get past.
So you get two picks, and then a full account of the eight popular machines we left out and exactly what was wrong with each. If you only read one section, read that one.
All figures in this guide were checked against live Amazon UK listings on 4 October 2026.
Quick picksHow we chose the best robot vacuums in the UK
No robot vacuum in this guide has been in our house. We have not tested them, and we will not pretend otherwise.
What we did instead was read the listings properly. For every machine we considered we checked whether the review count belonged to that model or to a whole family of models, whether the ASIN was old enough to have earned the reviews shown against it, whether the headline specification matched what owners were actually describing, and what Amazon’s own summary of the review text says rather than what the brand says.
That last one matters more than people realise. Amazon generates a Customers Say paragraph from the review text, along with mention counts by theme. It is the only part of a product page the seller does not control, and it is where the real drawbacks live.
We shortlist products sold in the UK, then analyse verified owner reviews for recurring praise, recurring faults and how products hold up over months of use. Unless a product is marked WHC Tested, we have not used it ourselves.
Read how we choose what to recommend →Why both of our picks are not from the same brand by accident
One of our two picks is a Roborock, and so are most of the near misses. That is not brand loyalty, and we are not paid by Roborock.
When we checked every robot vacuum on Amazon UK with a visible rating, only three machines outside Roborock carried more than a thousand reviews attached to that specific model rather than shared across a product family. Roborock has the volume because it has the sales, and because it lists its models separately instead of bundling them together.
In a category where most ratings cannot be traced to the machine arriving at your door, traceable is the whole point.
1. Roborock Qrevo S Pro
4.4 out of 5 from 1,689 ratings. 77% five star, 9% one star.
One review is worth reading before you buy, because it is the only one star we found that describes a failure rather than a disappointment. An owner bought it specifically to clean under her sofa, found it would not fit, then at three months reported internal faults and repeated disconnection from the app. Her closing note is that UK customer service is an email address. That is one account out of 1,689, and the overall nine percent one star rate is the same as the Tapo below, but it tells you where you stand if something does go wrong.
There is a 10,000Pa version of the same dock, listed as the Qrevo Series QV 35S, which sells for meaningfully less. Roborock is retiring it in favour of this model, so we have not given it a slot of its own, but if you find it in stock and the dock matters to you more than the suction figure, it is the same idea for less money.
2. Tapo RV30 Max Plus
4.3 out of 5 from 2,986 ratings. 69% five star, 9% one star.
The thing nearly every happy owner says
Read enough five star reviews of robot vacuums and the same sentence appears unprompted, from people who love the machine: do not throw away your real vacuum.
One owner with two cats, a dog and two children calls it the best purchase of the year and then writes, in capitals, that it is perfect for maintenance but not a hundred percent deep clean. Another says she still deep cleans weekly with a corded vacuum and uses the robot every second day in between. A third keeps a Henry for the stairs.
That is the honest shape of what you are buying. A robot vacuum changes how often your floors are clean, not how clean they can get. The people who are happiest with them run them daily or every other day and keep an upright for the weekend and the stairs. The people who are disappointed bought one expecting to throw the old one out.
If what you actually want is a machine that cleans properly rather than constantly, a cordless vacuum is the better buy at every price point on this page.
What makes the difference, and what does not
Suction numbers are mostly marketing. This category has an arms race running from 5,300Pa to 36,000Pa, and the machine with 36,000Pa in this guide rates lower than the one with 18,500Pa. No owner in any review we read complained that their robot lacked suction. They complained that it got stuck, mopped the carpet, lost the dock or could not fit under the sofa.
Obstacle avoidance is the real differentiator. It is also the hardest thing to buy. LiDAR builds an excellent map of walls and furniture and is nearly blind to anything low and small. Slippers, cables, shoelaces and pet bowls are what stop these machines, on budget models and premium ones alike. The fix is not spending more, it is a two minute tidy before it runs.
Mop lifting matters more than mop quality. A machine without it will drag a wet pad across your carpet, and owners of several models describe exactly that happening. If any part of your floor is carpet and you want the mop function, mop lifting is not optional.
Where the dock goes decides whether it works. One owner’s mapping was hopeless, repeatedly recleaning the same room, until she moved the dock out from beside the sofa into a hallway with space around it. Then it was faultless. Give the dock clear wall and clear floor in front of it before you blame the robot.
Thresholds are a hard limit. A centimetre is fine. Two inches is not, and no amount of climbing technology in the marketing will change that. Measure the worst step in your house before you order.
The robot vacuums we left out, and why
This is the section we would want to read. Every machine here is popular, several are bestsellers, and most other guides recommend them.
For each one we have given what the listing claims, what the data actually shows, and what would change our minds. Nothing here is a verdict on how well the machine cleans. In most cases that is precisely the point: we cannot tell you, because the evidence will not allow it.
Ratings we could not attribute to the machine
eufy Omni C20 and eufy C28 Omni. Both listings show 4.5 from 3,474 ratings. It is the same 3,474 on both, at two different prices, with the same Best Sellers rank on both, and both pages serve reviews for the eufy 15C and 11S Max dated 2019 and 2020. One pool covering at least four current models and two machines from seven years ago. In fairness, the C20 carries a Which? Best Buy badge from June 2026, which is worth considerably more than an Amazon average, and eufy is a serious brand in this category. This is not a verdict on the machine. We simply cannot tell you what its owners think.
What would change this: eufy splitting the review pools by model.
Lefant M5 Pro and M5max. Both show 4.3 from 1,288. The same 1,288 also appears against the Lefant M310. The colour options on these listings run from a used machine at under eighty pounds to a premium model at nearly five hundred, all sharing one rating. The reviews confirm it: one one star opens by saying she only paid seventy pounds, another is reviewing the M310 and M210, another says he chose the cheaper model and now wishes he had bought the one with the self-cleaning bin. The most useful and most entertaining review on the listing, about a robot with a death wish for the cables under its owner’s sofa, is almost certainly about a machine costing a quarter of the one being sold.
What would change this: separate listings per model.
Bagotte Robot Vacuum. 4.5 from 2,827 ratings, which looks excellent until you read them. They discuss the BG600 at 1,500Pa, dated 2019 to 2021, one quoting a price of a hundred and ninety-nine pounds. The current listing claims 8,000Pa and gives the model number as BG750 while the images say BG800 Pro. Separately, Amazon’s summary flags reliability as mixed, with some customers reporting it stops working after several months of use.
What would change this: a listing for the current hardware with its own reviews.
Support and specification problems
HONITURE G20 PRO. This one has its own 1,016 ratings at 4.3, so it clears the bar on paper. Two things stopped us. First, the specification has been relabelled: the listing says 10,000Pa, but the HONITURE brand panel on the same page lists this model at 4,500Pa, and owners from 2023 describe it in detail at 4,500Pa. Same machine, headline figure more than doubled. Second, and more seriously, one of the customer videos on the listing is titled Three Months Lifespan, and a detailed one star describes a faulty component, support acknowledging it, a replacement part promised repeatedly over several weeks, and nothing ever arriving before communication stopped. Two further owners report failures inside a month with the brand declining to help and Amazon stepping in instead.
What would change this: an honest spec and some evidence the after-sales has improved.
Too new to judge
The Shark robot range. Shark’s current robots sit at 90, 91, 64, 28, 92, 123 and 32 ratings depending on the model, several of them selling for many hundreds of pounds. We like Shark and they appear elsewhere on this site on the strength of thousands of reviews. These machines are simply too new. Buying one means being part of the sample rather than reading it. Worth noting that one of our Qrevo owners bought it after returning a Shark robot that did not live up to expectations, which is a single data point and not a verdict.
Dreame, Ecovacs, Xiaomi, Proscenic, Vexilar and Dyson. Current flagship models at 68, 247, 665, between 72 and 222, between 14 and 808, and 48 ratings respectively. Some of these will turn out to be very good. There is no way to know yet.
What would change this: time.
More expensive, but rated lower
Roborock Saros 20. The Roborock flagship, at roughly two and a half times the price of our first pick, scores 4.2 with eleven percent one star. Its rating pool is not clean either, including a Swedish review from 2023 and an Italian one from 2024 about a machine whose listing gives a manufacture year of 2026, plus one headed with a different model name entirely. The detailed one star is instructive: it drove onto carpet with the mop still engaged and soaked it, tried to climb dining chair legs and got stuck repeatedly, and needed remapping three times. If you assume that spending more buys reliability in this category, that is the review to read.
Cheaper, but rated poorly
Roborock Q10 S5, Q10 S5+, Q7 L5+ and Q7 M5. The affordable end of the Roborock range rates 3.9, 3.9, 3.7 and 4.1, against 4.3 and 4.4 for our two picks. The Q7 M5 is the pick of them on rating and still carries thirteen percent one star, which is half again the rate of either machine we recommend. It also has no obstacle avoidance and no mop lifting, so with the mop fitted it will wet your carpet, and one owner describes exactly that happening in her hallway. Amazon’s summary says some owners find it just pushes dirt around.
What would change this: better ratings, which may come as these models mature.
Which of the two
If your home is a mix of hard floor and carpet, you want the mopping done properly, and the appeal of a robot is that it deals with itself, the Roborock Qrevo S Pro is the one. The dock washing and drying the mops is the feature that stops a mopping robot becoming a chore in its own right.
If your downstairs is mostly hard floor, this is your first robot, and what you actually want is for the vacuuming to happen daily without you thinking about it, the Tapo RV30 Max Plus does that for a great deal less. Leave the mop attachment in the box if you have carpet.

Robot vacuum questions
Common questions
Will a robot vacuum replace my normal vacuum?
No, and the owners who love them say so themselves. Read through the five star reviews of any robot vacuum and the same line appears unprompted: do not get rid of your old one. A robot changes how often your floors are clean rather than how clean they can get. It cannot do stairs, it will not shift ground-in dirt, and it misses corners by an inch or two. The people happiest with theirs run one daily or every other day and keep an upright for the weekend.
Why do so many robot vacuums show thousands of reviews that do not match the model?
Amazon allows a seller to group several products under one listing as variations, and the star rating is then shared across all of them. It is designed for genuine variations such as colour, but in this category it is routinely used across completely different machines and across generations. We found one listing whose options ran from a used machine under eighty pounds to a premium model near five hundred, all sharing a single rating, and another where reviews from 2019 for a discontinued model appeared against a machine launched this year. Before you trust a review count, scroll down to the reviews and check what the owners are actually describing.
Do I need the self-emptying dock?
It is the feature most worth paying for, more than suction and more than mapping. Without it you empty a small bin every clean or two, which is the daily job you bought the robot to avoid. With it you change a sealed bag every two months or so. If your budget stretches to only one upgrade, make it this one.
Will a robot vacuum work on carpet?
On low and medium pile, yes, and most will raise suction automatically when they detect it. Two things to watch. Deep pile and long tassels will stop them, and lightweight rugs get pushed around until you fit anti-slip pads underneath. More importantly, if the machine has a mop and no automatic mop lifting, it will drag a wet pad straight across your carpet. Some models solve this by refusing to clean carpeted rooms at all while the mop attachment is fitted, which is a surprise worth knowing about in advance.
Do robot vacuums get stuck?
Regularly, and almost always on the same handful of things: cables, slippers, shoelaces, low pet bowls, rug tassels and the bases of swivel chairs. Navigation technology has largely solved walls and furniture and has barely touched small low objects, on expensive machines as much as cheap ones. A two minute tidy before it runs is the real answer. Most apps also let you draw no-go zones around the cables behind a TV stand, which owners say works well.
How much maintenance is there really?
More than the marketing suggests, less than vacuuming yourself. Even with a full dock you will top up clean water and empty dirty water weekly if you mop, change a dust bag every couple of months, clear hair from the brush, and wipe the mop washing plate in the dock occasionally. Owners of machines with mop washing and warm air drying report the biggest saving, because a damp pad left in a tray starts to smell within a few days and hand washing it is the job people give up on first.
Is more suction better?
Barely. Suction figures in this category have run from about 5,000Pa to 36,000Pa in a few years, and the 36,000Pa machine in this guide rates lower than the 18,500Pa one. Across hundreds of reviews we read, not one owner complained that their robot lacked suction. They complained about getting stuck, mopping carpet, losing the dock and not fitting under the sofa. Spend your money on the dock and the body height instead.
