Dreame Aqua10 Ultra Roller Complete

The Aqua10 Ultra Roller Complete mops with a spinning roller instead of a flat pad: it self-cleans while mopping, and the dock heats it to 100 °C and dries it with warm air after every run, dosing detergent on its own. The dock's two tanks, 4 litres of clean water and 3.5 of dirty water, fill and empty themselves; the kit that connects it to the plumbing is sold separately. When the roller meets a carpet, the AutoSeal protection seals it to keep it dry.

A pair of stereo cameras and a structured-light projector recognise obstacles; the body drops to 9.75 cm when the mapping laser sensor retracts to pass under furniture, and rises to 12 cm when a full scan is needed. Two retractable legs lift the frame over thresholds: 4.2 cm on a single step, up to 8 cm over two closely spaced steps.

The filter rinses with clean water only, no detergent. Wi-Fi is 2.4 GHz only, Matter support will arrive with an update not yet released, and the battery can only be replaced by a service centre. It suits someone after continuous mopping without a pad that gets dirty, who accepts the bigger, pricier dock of the D and L range.
