Our Verdict

Dreame X50 Ultra

Roborock Qrevo Curv 2 Flow

The Dreame X50 Ultra and the Roborock Qrevo Curv 2 Flow are both robot vacuum and mop combos, but they have different strengths. If obstacle avoidance is a priority, the X50 Ultra is the better pick, because it detects and avoids objects far more reliably on both hard floors and carpet. The Curv 2 Flow has the edge when it comes to hard floor debris pickup and stain removal, where its roller mop applies more consistent pressure than the X50's spinning pads. Both models handle carpet similarly, though neither excels at pet hair.
