Xiaomi S40 Pro Robot vacuum cleaner

The Xiaomi Robot Vacuum S40 Pro utilizes LDS laser navigation to accurately map and structure the cleaning area. Movement is supported by integrated obstacle detection via a 129° ultra-wide-angle structured light system, allowing the unit to maneuver efficiently even in low-light conditions. The robot is capable of crossing internal thresholds up to 20 mm and includes separate sensors for stairs detection, preventing accidental falls. Cleaning path planning ensures systematic coverage of the floor surface.

The cleaning apparatus employs a Y-shaped anti-tangle roller brush designed to manage debris across hard floors and carpets, activating a boost function when required. Vacuum performance operates across four adjustable suction levels, providing up to 15,000 kPa for debris removal into the 0.43 L bagless container. Wet mopping functionality is integrated, utilizing a 0.31 L water tank.

The included base station manages charging and automatically retracts the mop pads when the unit docks, preventing unwanted floor saturation. Filtration relies on a washable HEPA H13 system designed to capture fine particulate matter. Control is managed via the companion application over WiFi, and voice control integration is supported through both Amazon Alexa and the Google Assistant ecosystem. The unit reports a nominal operational noise level of 58 dB.
