The best cheap robot vacuums in the UK
Eight robots between £329 and £649. Cheap machines are where marketing numbers drift furthest from the truth, so every price here was read from the seller's own page and every figure two sources disagreed on has been left blank.

30,000Pa claimed, a 100°C mop wash, a 40mm climb and a 100-day bin for £529. Only Dreame's own page describes it and no outlet has reviewed it, so treat those figures as the manufacturer's claims.

How we chose
Three separate signals, never one invented score. Read the full method.
- Every pick is under £650 at the seller's own page and has a dock that empties the bin. Bare robots with no dock were excluded because their running cost is your time.
- Prices were read from the seller's page in a browser on the date shown. Where a model had more than one live price we quote the product page and say so.
- Specifications are shown only where sources agree. The L10s Ultra Gen 2 and L50 Ultra AE each have several contradicted figures, and those cells are blank.
- Reviews are attached only where the outlet tested the exact model.
- Some links may become paid affiliate links in future and will be labelled. Commission never changes the order.
Questions people ask
What is the best cheap robot vacuum in the UK?
The Roborock Qrevo S Pro at £379.99: a full self-cleaning dock and LiDAR at a price where most rivals give you a bin and a bumper. If it is out of your budget, the Dreame L10s Ultra Gen 2 at £329 is the next step down.
Is a £300 robot vacuum any good?
It can be, if it has LiDAR and a dock. Below that price you mostly lose the dock, and then you are emptying a small bin every run. The two cheapest picks here both keep the dock.
Do budget robots handle carpet?
The ones with lifting mops do — the Qrevo S Pro, X10 Pro Omni and L10s Ultra Gen 2 all lift or raise their pads. Check the mopping column before buying a combo for a carpeted home.
Why are two Dreame models shown with blank specs?
Because Dreame's own pages and Currys publish different numbers for them — suction, navigation, runtime, self-empty interval. We show a figure only when the sources agree.
