Dreame D30 Ultra vs Roborock Qrevo Curv 2 Flow

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Dreame and Roborock sites.
2026 verdict
25000Pa and a 3-year warranty hold the line: the Dreame D30 Ultra wins this robot vacuum comparison against the Roborock Qrevo Curv 2 Flow, adding a lower price, a larger 3.2L dock bag, and a bigger water tank.
The Curv 2 Flow answers with a 242-minute battery versus 230, a self-rinsing roller mop, and a slightly better-reviewed package plus upcoming Matter. Both are LiDAR combo robots with self-emptying wash-and-dry docks. Choose the Dreame D30 Ultra for suction and ownership terms; choose the Roborock Qrevo Curv 2 Flow if the roller mop and extra minutes matter more than 25000Pa.
