Roborock QV 35S
Affordable full dock robot that shines on hard floors
Researched by Riley Hart · updated Oct 30, 2026
Is the Roborock QV 35S worth it? A good value full dock robot for homes that are mostly hard floor. It costs $550 as of Nov 4, 2026, and 2 independent reviewers tested it.
A good value full dock robot for homes that are mostly hard floor. Tom's Guide and Ideal Home both found it excellent on hardwood and tile but weak on thicker carpet and pet hair in rugs. Skip it if you have lots of high pile carpet or heavy shedding pets.
Best for: mostly hard floor homes on a mid budget. Skip if: you have high pile carpet or heavy shedding pets.

What independent reviewers found
- On hardwood it picked up 92% hair, 94.5% puffed rice and 98% flax seeds. On high pile carpet it got 40% hair and 38.5% flax seeds. About 55 dB mopping and 60 dB vacuuming. Called it ideal for hardwood homes.
- Tom's Guide
- Handled rice, flour, ketchup and dog hair on hard floors, mapped each floor in about 5 min, and had about 40% battery left after the whole house. Weaker on carpet and dog hair in rugs, and the app was buggy at times.
