Roborock Qrevo Curv vs Dreame L40 Ultra

The Dreame L40 Ultra and the Roborock Qrevo Curv are both premium robot vacuums with mopping capabilities and deep feature sets. In addition to seemingly countless customization options, design-wise, both vacuums offer extendable side brushes and mops for dealing with traditionally hard-to-reach areas for robot vacuums with a circular design, like along walls and in corners. That said, the Curv outperforms the L40 in terms of debris pickup. This is because the Dreame model's pathing is finicky, often dragging debris around as it positions itself and ineffectively covering surfaces. That said, the Dreame's hazard avoidance system does a better job of guiding the vacuum around hazards like socks or shoes, as well as furniture.
