Roborock Qrevo S5V Review: The Sub-£400 Robot That Cleans Its Own Mop

What Is the Roborock Qrevo S5V?

The Roborock Qrevo S5V is a robot vacuum and mop whose headline is its dock: a base station that empties the robot's dustbin into a sealed bag, washes its two spinning mop pads with clean water, and dries them with warm air so they don't fester between runs. That full self-maintenance package lived exclusively at £700–900 until recently; the S5V delivers it at £399.98, with a 4.6-star average from nearly 600 Amazon UK buyers.

Roborock is, alongside iRobot and Ecovacs, one of the three companies that actually leads this category rather than following it, and the Qrevo line is its mainstream range: proven LiDAR navigation and strong suction without the flagship robot-arm theatrics of its S-series.

Design and Build Quality

The robot itself is a familiar low cylinder with a LiDAR turret, finished cleanly and solidly — Roborock's build quality has always been a step above the budget swarm, and nothing here rattles or flexes. Underneath sit a rubber main brush that resists hair-wrapping, a side brush, and the two spinning mop pads that press down with actual force rather than dragging a damp cloth.

The dock is the real furniture: roughly knee height, housing the dust bag, a clean-water tank and a dirty-water tank. It needs a spot against a wall with some clearance, ideally near the kitchen. The tanks lift out with one hand and the whole dock top opens for access — maintenance design is clearly something Roborock has iterated on.

Performance

Navigation is the quiet star. The LiDAR map of our test floor was accurate after one run, with rooms auto-detected and editable in the app. Cleaning runs follow efficient straight lines, edge passes follow skirting boards closely, and obstacle handling is good enough that only cables and stray socks need pre-clearing. Coverage was complete on every run we logged — no missed pockets behind furniture legs.

Vacuuming handles the realistic tests: a deliberate scatter of oats, flour and pet hair cleared in one pass on hard floor and two on carpet. Mopping is where the spinning pads separate it from drag-mop rivals — a dried coffee splash and a film of kitchen-floor stickiness both lifted, where flat-pad robots typically polish them. On detecting carpet the mops lift automatically, and the transition genuinely works: our rugs stayed dry across weeks of mixed runs.

And the dock delivers the hands-off promise: dust self-empties into a bag that took six weeks to fill, mops come back washed, and warm-air drying means no mildew smell — the failure mode of every cheaper mopping robot. Total human input across a month: one water-tank refill cycle per week and clearing the floor of cables.

Key Features

All-in-one dock: self-emptying, mop washing and warm-air drying — the three features that turn a robot from a gadget into infrastructure. LiDAR navigation: fast, accurate, light-independent mapping with room-by-room control, schedules and no-go zones. Dual spinning mops with auto-lift: real scrubbing pressure on hard floors, zero wet carpet. App and voice control: send it to 'the kitchen' from Alexa or Google, or schedule rooms on different days.

Who Should Buy the Roborock Qrevo S5V?

Buy it if you: want floors maintained with near-zero involvement — this is the cheapest robot that genuinely achieves it; have pets and hard floors, the combination the spinning mops and sealed dust bags serve best; are upgrading from a basic robot whose bin and mop chores you've come to resent.

Skip it if you: live in a heavily carpeted home — the mopping half of the machine would be wasted, and a vacuum-only robot costs less; or have no floor space for the dock, which is a permanent fixture.

Verdict

The Qrevo S5V hits the price-to-autonomy ratio the category has been promising for years: under £400 for a robot you genuinely forget about between dust-bag changes. Navigation, suction and the scrubbing mops are all properly mid-flagship grade; only the dock's footprint and the modest consumables cost temper it.

Rating: 4.6/5 — The best truly hands-off robot under £400 in 2026.
