## What reviewers found

### Roborock Qrevo Curv 2 Flow

- CyberShack (8.7/10): Excellent hard floor vacuuming at 91% to 95% and good mopping close to skirting, above average on short and medium pile carpet, but weak on carpet pet hair and no edge or corner cleaning on carpet. Measured 100 to 125 minutes of real runtime. [Source](https://cybershack.com.au/cleaning/roborock-qrevo-curv-2-flow-another-great-robovac-roller-mop-review)
- Gizmodo: Called the roller mop the most powerful robot mop it had tested where it can reach, with good hair and sand pickup, but edge gaps of around 8 inches at times, a swallowed USB C cord and sock, and limited battery for large homes. [Source](https://gizmodo.com/roborock-qrevo-curv-2-flow-review-ultimate-robot-mop-if-you-dont-have-corners-or-walls-2000745723)
- Vacuum Wars (3.64/5): Strong vacuum with 87% carpet sand removal and 0% hair tangles, but a combined mopping score of 13.7 against a 22.75 category average and 16 of 24 obstacles avoided. Headline verdict: strong vacuum, disappointing mopping. [Source](https://vacuumwars.com/roborock-qrevo-curv-2-flow-review)

### 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](https://www.tomsguide.com/home/roborock-qv-35s-review)
- 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](https://www.idealhome.co.uk/house-manual/floorcare/roborock-qv-35s-robot-vacuum-with-mop-review)
