What reviewers found
Roborock Qrevo CurvX
- TechGearLab (85/100): Ranked first of 23 robots. Hard floor and mopping 9.3, carpet 8.4 with about 79% of debris cleaned, but only 52% of pet hair. Avoided 88% of obstacles. Measured 56.3 dB vacuuming. Source
- Vacuum Wars (3.69 Vacuum Wars stars): Long term test in a 750 sq ft home with a dog. Mopping was strong with vacuum then mop runs and nothing wrapped the brush, but the 260 ml bin clogged almost daily and it often tried to climb objects and needed help. Source
Roborock QV 35S
- Tom's Guide: 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. Source
- Ideal Home: 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. Source
