Scrubs away stainsA vibrating mop pressing on the floor.
Right to the edgeThe mop extends to walls and corners.
Over thresholdsLifts its chassis over two-step thresholds.
Hot and dryThe mop is washed hot and dried with warm air.

Thresholds are no obstacle

Sliding-door rails, bathroom thresholds and uneven transitions between rooms it climbs by lifting its chassis – according to Roborock up to 4.5 + 4.3 cm in two steps. It also drives out of U-shaped furniture legs where other robots get stuck.

A dock that washes while the robot vacuums

The dock washes the mop separately with up to 100 °C water, so the robot can keep vacuuming meanwhile. Afterwards the mop and dust bag are dried with 55 °C warm air, and the dock doses cleaning solution and refills hot water.

Out of the dock and under the furniture

The retractable LiDAR sensor lowers when the robot drives under furniture, so it reaches spaces down to 7.95 cm, and rises again for a 360° map in open areas.
