TL;DR - The Xiaomi Robot Vacuum X20+ launched at GBP 299 with 6,000 Pa, two spinning mops and a station that empties the bin, washes the pads and dries them. TechRadar called the package "a steal" at the price. NextPit's lab found solid hard-floor pickup, weak carpet pickup and damp carpet edges, and advises against it for homes with a lot of carpet. For hard floors with pets, it's the budget pick. For carpeted homes, spend more.
Updated October 2026: An earlier version of this page described the X20+ as tested here, with a spec table that said 4,000 Pa and vibrating mop pads while the text said 6,000 Pa and spinning mops, a "bagless" station that in fact uses a 2.5-litre bag, and a star rating. Nobody on this site has used the robot. The page was rewritten from Xiaomi's UK spec page and the published tests at TechRadar and NextPit, and the hands-on claims and the rating were removed.

What Do You Get for GBP 299?
The X20+ launched into a market where a robot with a self-washing station typically started at GBP 500 or more. Xiaomi's answer was a full-featured machine: LiDAR navigation, two spinning mops, a station that empties the bin and washes and dries the pads, 6,000 Pa of suction and a pair of 4-litre tanks. TechRadar's verdict on the price was blunt: "At a snip under GBP 300, this package is a steal," with a 5 out of 5 for value.
To put 6,000 Pa in context, Xiaomi's own X20 Pro moves to 7,000 Pa at an RRP of EUR 499.99 in Germany, and the X20 Max goes to 8,000 Pa at EUR 649.99. The X20+ matches the entry-level spec of machines that cost noticeably more, and the station does the same three jobs as the premium ones.
Is there a catch? A few. The published tests found them.
How Does the Cleaning Performance Stack Up in Published Tests?
NextPit's lab put the X20+ at 86 percent pickup for oat flakes on tile and 84 percent for sand on tile. On carpet, sand pickup dropped to 73 percent. Those aren't standout numbers, premium machines pull 90 percent and up, but they're solid for the price tier. NextPit's wording on carpet was less kind than the number: "the suction power on carpets is not convincing either."
Where the X20+ earns its price in that test is hair. NextPit found no tangled hair on the side brush or the roller after its practical run. A rubber roller lets hair slide off the ends instead of matting around the axle, which is a design difference rather than a tuning one, and it's why the machine suits exactly the homes where bristle machines don't.
Noise is listed at 68 dB maximum in TechRadar's spec box. That's not silent, you'd notice it if you were trying to sleep, but it's fine for daytime runs.
Is the Base Station Where the X20+ Earns Its Money?
The station handles auto-emptying into a 2.5-litre bag, mop washing and hot-air pad drying. You fill a 4-litre clean tank, the dirty water goes into a separate 4-litre tank, and the station washes the pads after each run. Xiaomi quotes up to 75 days between bag changes, which is a manufacturer's figure for a tidy home, not a promise.
That means you don't touch the mop pads between emptying sessions, which is the whole promise of a self-maintaining robot, delivered at a price point where competitors don't.
The station itself is big: 586 x 427 x 340 mm, roughly the size of a kitchen bin. TechRadar's reviewer wrote that "it's an incongruous white plastic monolith that sticks out like a sore thumb," and listed the "huge, unattractive cleaning base" as the main reason to avoid the machine. If the station has to sit in a hallway rather than a utility room, that's the trade.
What Are the Honest Downsides?
Carpet detection isn't reliable. The mop pads are supposed to lift up to 7 mm when the robot detects carpet. NextPit's conclusion was that it "leaves damp carpet edges in practice and the carpet detection does not work perfectly," and the testers added that carpets had to be added to the map by hand. Xiaomi's own spec page says the same thing more quietly: if the carpet is thicker than 5 mm, set the app to avoid carpets. Workaround: draw no-mop zones around your rugs once. It takes ten minutes, but you shouldn't need to.
Battery runs short on large homes. 140 minutes is enough for most UK homes under 100 sq m, but a large open-plan space or a multi-floor layout may need a mid-run dock-and-recharge. The robot resumes on its own; the run just takes longer.
No cleaning agent dispenser. Premium machines like the Dreame L20 Ultra dispense cleaning solution from the station, and the Samsung Jet Bot Steam Ultra uses steam at 100 degrees C, per Samsung, instead of detergent. The X20+ uses plain water only. For most households that's fine, but heavily used kitchen tile will show the limitation.
No US availability. If you're reading this from North America, the X20+ isn't for you. NextPit says it plainly, and Xiaomi doesn't sell it there.
How Good Are the Navigation and App?
LiDAR navigation maps from the first run, and the Xiaomi Home app offers zone scheduling, no-go zones, cleaning history and per-room suction and water levels. TechRadar's one reservation was that "obstacle avoidance isn't quite up there with the iRobot bunch," so cables on the floor are still your job.
One gap NextPit called out: the app doesn't show a battery percentage during a run, only a bar. You can't tell whether it'll finish the floor before needing to dock, which is a careless omission on a machine this polished elsewhere.
Voice control works with Google Assistant and Amazon Alexa.
Where Does the X20+ Sit in Xiaomi's 2026 Range?
The line has grown since launch, and the X20+ is no longer the obvious pick within its own family. Above it, the X20 Pro moves to 7,000 Pa at EUR 499.99, and the X20 Max adds 8,000 Pa and an extendable mop arm at EUR 649.99, both RRPs from German launch coverage. If mopping is your main reason for buying, the step up inside Xiaomi's own range is where the money goes.
Availability has shifted too. The X20+ is now the older model in an active lineup, which usually means better discounts and a shorter shelf life; PriceSpy UK has shown it under GBP 280. Check whether the retailer is clearing stock before you assume the price you see is a bargain rather than a run-out.
Who Should Buy the Xiaomi X20+?
Buy it if:
- You have mainly hard floors (tile, wood, LVT) and pets
- GBP 300 is your ceiling for a robot vacuum with a self-cleaning station
- You're in the UK or EU, where it's officially sold
- You're willing to mark carpet areas in the app yourself
Don't buy it if:
- Your home is mainly carpeted; NextPit says so outright
- You need a machine for a home over 120 sq m with stairs or complex layouts
- You want certainty that the mop pads won't reach carpet, in which case spend more on a Roborock
The X20+ launched at GBP 299 through Xiaomi UK and major UK electronics retailers. In this price band Xiaomi holds the best value-for-money position. The closest European-brand rival in spirit is covered in our PURON PR12 Pro review, a self-emptying machine that adds UV mop sterilisation but loses on suction.
