## 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 S8 MaxV Ultra

- TechRadar: Strong vacuuming and effective mopping on coffee and dried honey, fast accurate mapping. It got stuck on cables repeatedly, tried to vacuum a sock, and the extending side brush and voice assistant were unreliable. Subscores: Value 3.5/5, Design 4.5/5, Performance 4/5. [Source](https://www.techradar.com/home/robot-vacuums/roborock-s8-maxv-ultra-robot-vacuum-review)
- Vacuum Wars: Measured 0.18 kPa max suction and 13 CFM airflow, 1.41 min per 1% battery and 0.62 m² per min navigation. Handled dried coffee and grape juice stains with minimal streaks, and its feature score was the highest Vacuum Wars had recorded at the time.
