Prices from the maker or retailer named on each pick below, checked 25 October 2026. A dash means the price changes too often to quote: tap through for today's.

A robot that vacuums and mops for you, for under £300 at the maker's regular price: these are the four best. Three things decide the choice: the dock (does it empty itself, and does it wash the mop?), the suction, from 5,000 Pa to 13,000 Pa, and how the mop handles carpet. Some lift the mop on carpet, while others skip carpet altogether.

1★ Top pickBest for most budget buyers

Roborock Q10 S5+ Robot Vacuum with Auto-Empty Dock

Strong suction, anti-tangle system and a self-emptying dock.

What it is: The Roborock Q10 S5+ uses 10,000 Pa HyperForce suction, a strong pull for dirt and dust, and its RockDock Plus empties the bin for you. Roborock says the large dust bag lasts up to 7 weeks, so emptying is rarely on your to-do list.
Perfect for: Anyone who wants the lowest-priced self-emptying robot here, with laser mapping.
Why we picked it: The VibraRise 2.0 vibrating mop lifts automatically on carpet, and suction boosts on carpeted areas. PreciSense LiDAR navigation guides it through your rooms, and a 5200 mAh battery runs for up to 150 minutes, according to Roborock.
Price: £189.98 (uk.roborock.com, checked 25 October 2026)

2Best for big water tanks

Xiaomi Robot Vacuum H50

Mop more floor in one go with big water tanks.

Perfect for: Homes with lots of hard floor, where the mop pads need washing after every run.
Why we picked it: The dock washes the mop pads for you and dries them after cleaning, so you do less work. It uses LDS laser navigation and crosses obstacles up to 20 mm high. Its extra-large dust bag lasts up to 75 days, says Xiaomi.

3Best for most suction for a self-emptying dock

Tapo RV30 Max Plus Gen2 Robot Vacuum & Mop with Compact Auto-Empty Dock

Strong suction and a compact dock that empties itself.

What it is: A robot vacuum and mop with 13,000 Pa suction, the power it uses to pull dirt up. Tapo says that is 245% more suction than the previous generation, and the dock empties the dust for you.
Perfect for: Carpet-heavy homes that want the most suction here and a dock that fits a small hallway.
Why we picked it: Carpet settings boost suction on carpet, and the mop avoids carpets when mopping. Tapo says the tangle-free brush detangles hair automatically in the dock. Its 2600 mAh battery runs for up to 150 minutes in Quiet Mode, all in a compact package.
What's new: Tapo says suction rises to 13,000 Pa, 245% more than the previous generation, with a new tangle-free brush and a compact dock.
Price: £199.99 (uk.store.tapo.com, checked 25 October 2026)

It has 13,000 Pa suction and a tangle-free brush that Tapo says detangles hair automatically in the dock.
The compact dock holds a 3.3 L dust bag that Tapo says gives up to 90 days hands-free.
The datasheet lists a 2600 mAh battery, up to 150 minutes in Quiet Mode, and a 300 ml water tank with 3 water levels.
Carpet settings boost suction on carpet and avoid carpets when mopping.

The catch: The water tank holds 300 ml and the dock empties dust only, with no mop washing listed on Tapo's pages.

4Best for lowest price, slim body

Hoover HG2 Hydro TurboSlim Robot Vacuum Cleaner & Mop (HG230H)

What it is: This robot vacuums and mops at the same time, so one run gives you cleaner floors with less effort. Its 8.3 cm tall body is built for cleaning under furniture.
Perfect for: Small flats with low sofas and beds, where a dock would not fit anyway.
Why we picked it: It has 5,000 Pa suction, and Point Laser Navigation scans and updates your home layout. Hoover says it runs for up to 160 minutes on one charge, and you choose three water levels in the HG Robots app.

How we chose

Our buying criteria

To make this list, a robot had to vacuum and mop, cost under £300 at the maker's regular UK price (not a short-term offer) and be in stock on Amazon UK. Suction is stated in Pa (pascals): how hard the robot pulls dirt up. Every pick is checked against the maker's UK spec sheet and live UK listings, with one honest catch each.

Dock type: dust-only auto-empty, mop washing and drying, or no dock at all.
Suction, from 5,000 Pa to 13,000 Pa.
Carpet handling: a mop that lifts, or a robot that avoids carpet while mopping.
Navigation: laser or LiDAR mapping plans a tidy route, room by room.

How we choose every pick

Your questions, answered

Do I need a self-emptying dock on a budget robot vacuum?

Not strictly, but a dock means less emptying for you. The Roborock Q10 S5+ comes with a RockDock Plus, and Roborock says its large dust bag lasts up to 7 weeks without emptying. Prefer a compact dock? The Tapo RV30 Max Plus Gen2 fits that, and Tapo says the compact dock's 3.3 L dust bag gives up to 90 days hands-free.

Which of these robot vacuums wash their own mop pads?

One does: the Xiaomi H50's dock washes the mop pads automatically, then dries them after cleaning.

Do budget robot mops cope with carpet?

Three of them keep the mop off carpet. The Roborock Q10 S5+ lifts its VibraRise mop automatically on carpet. The Xiaomi H50 lifts its mop pads on carpet only in zones you set up in the Xiaomi Home app. The Tapo RV30 Max Plus Gen2 has carpet settings that avoid carpets when mopping.

Do lower-cost robot vacuums map your home with a laser?

Most do. The Roborock Q10 S5+ uses PreciSense LiDAR navigation, and the Hoover HG2 Hydro TurboSlim uses Point Laser Navigation. The Xiaomi H50 uses LDS laser navigation.

How long is the warranty on a budget robot vacuum?

The Roborock Q10 S5+ comes with a 2-year warranty from Roborock.
