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
Dreame X50 Ultra
- Vacuum Wars (3.60 Vacuum Wars stars): Removed 83% of embedded sand and 98% of pet hair with 0% hair wrap and avoided 20 of 24 obstacles. Dried stain score was 80 against a 94 average. Estimated coverage was about 1,130 sq ft per charge. 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
