Our verdict
At this end of the market most robot vacuums come with a charging plate and a bin you empty by hand. The QV 35A comes with the whole dock: it empties the bin, washes the mops in three stages, dries them and refills the water tank, and that is the case for it. Everything else is the budget version of the idea. 8,000 Pa is a fraction of what the flagships quote, so deep carpet is not its territory; the wash uses cold water and the drying cold air; obstacle sensing is structured light with no camera behind it; and carpet handling is a set of strategies you set in the app, with the main brush turning 10% faster at maximum power, rather than a claimed boost. What you get is a machine that maps properly with LiDAR, spins its twin mops at 200 rpm and lifts them for rugs, crosses a 20 mm threshold and asks nothing of you for weeks. Roborock publishes neither the chassis height nor any capacity, and the warranty is one year.
Pros
- Full self-maintaining dock: emptying, three-stage mop washing, drying and water refill
- Proper LiDAR mapping with no-go zones at a budget price
- Twin 200 rpm spinning mops that lift clear of carpet
- Anti-tangle rubber main brush and arc side brush
- Crosses 20 mm thresholds
Cons
- 8,000 Pa, a fraction of the flagship figure, so deep carpet is not its territory
- Cold-water washing and cold-air drying, no heat anywhere in the dock
- Structured light only, no camera, so cables and pet mess are a risk
- No voice control; chassis height and capacities are not published
Best for
- Hard floors and low-pile rugs
- A first robot vacuum where the dock matters more than raw power
- A second machine for a flat or an upstairs floor
Not recommended for
- Deep carpet or heavy pet hair
- Cluttered floors, since there is no camera to recognise what is on them

In detail
Suction and brushes
The manufacturer rates the suction at 8,000 Pa. That is less than most of the 111 robot vacuums we list. The main brush is the tangle-resistant type, with one side brush.
Mopping
Mop system: twin spinning pads. It lifts the mop over carpet.
Navigation and obstacles
It navigates by LiDAR and avoids obstacles with structured light. It climbs thresholds up to 20 mm. That is less than most of the 69 robot vacuums with a published figure. No-go zones can be drawn in the app.
The dock
The dock empties the bin, washes and dries the mop and refills the water tank.
Battery, charging and noise
The manufacturer publishes neither a runtime nor a noise figure.
