The LDS laser navigation system quickly maps your home and helps the robot plan efficient cleaning routes. It supports 360° mapping, multi-storey maps, and precise navigation to reduce missed areas, repeated cleaning, and navigation errors.
Through the Xiaomi Home app, you can personalise your cleaning experience with room cleaning, area cleaning, scheduled cleaning, custom zones, restricted areas, and virtual walls. You can also set specific carpet cleaning preferences, including carpet avoidance or vacuum-only cleaning.
Multiple sensors help the robot detect its surroundings, avoid obstacles, detect steps, and prevent falls. It can also automatically return to the charging dock when the battery is low and cross door thresholds up to 20mm high under specified conditions.
The Xiaomi Home app allows you to control and monitor the robot remotely. You can start or stop cleaning, schedule cleaning times, check cleaning history, activate the child lock, and receive OTA updates.
