A former flagship that now costs about $800, with one of the best mops Vacuum Wars has tested and very strong airflow. It suits homes with lots of hard floor and pets. Skip it if you need long runtime per charge or a big onboard bin, or if fringed rugs are common in your home.

- Runtime

A strong pick for apartments and homes that are mostly hard floor, because the self cleaning roller mop scrubs harder than the spinning pads on older Qrevo models. Reviewers found edge and corner cleaning inconsistent and small object avoidance only average. Skip it if you have low furniture, lots of carpet or want detergent dosing built into the dock.

What reviewers found
Ecovacs Deebot X9 Pro Omni
- Vacuum Wars: Measured 2.76 kPa suction and 27 CFM airflow, 93% pet hair pickup, 0% hair wrap, 158 of 184 on dried stains and 89% carpet deep clean. Coverage was 876 sq ft per charge against a 1,015 sq ft average. Source
- MacRumors: Three months of testing. Long hair did not tangle the brush, mopping and navigation beat the X8 Pro Omni, and Siri control through Matter worked. Thin rugs caused frequent tangles and vacuuming was loud. About 1,000 sq ft per charge. Source
- BGR (9/10): Called the roller mop the best robot mop available and vacuuming very good. Mapping was error prone and needed about 20 minutes of fixes, and tanks are no longer see through. Source
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
- 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
- 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
