Xiaomi Robot Vacuum S40

10,000Pa Suction, Laser Mapping and Three Hours of Runtime

The Xiaomi Robot Vacuum S40 brings serious cleaning power to a compact, minimalist white body. Its fan generates up to 10,000Pa of suction in Turbo mode, pulling dust, crumbs and pet hair out of hard floors and carpets alike, while four power levels (Silent, Standard, Strong and Turbo) let you balance noise against intensity for each room.

An LDS laser navigation system scans the room in 360° to build an accurate 3D floor map, then plans efficient routes so no area is cleaned twice or missed. Multi-story map memory means the S40 works just as well in a multi-level home. The V-shaped anti-tangle main brush keeps hair from wrapping around the roller, and the robot clears thresholds up to 20mm high while cliff sensors stop it from tumbling down stairs.

Vacuuming and mopping happen in a single pass thanks to an integrated 270mL electronic water tank with three flow levels. A 5,200mAh battery delivers up to 180 minutes of combined vacuuming and mopping, and the 520mL dustbin needs emptying far less often. Everything is managed through the Xiaomi Home app, with scheduling, remote start, no-go zones and child lock, plus voice control through Amazon Alexa and Google Assistant.
