XIAOMI Robot Vacuum S40 with mopping and LDS laser mapping

Vacuums and mops in a single pass, following a laser-generated map of your home.

The Xiaomi Robot Vacuum S40 is a vacuum-and-mop robot with LDS laser navigation, controlled from the Xiaomi Home app. Its 520 ml dustbin and 270 ml water tank cover a full apartment without a refill, and the robot returns to the dock on its own when the battery runs low.

10000 Pa suction for fine dust and pet hair

The turbine runs in four levels: Silent, Standard, Strong and Turbo. The top level handles carpets and coarse debris such as crumbs or coffee grounds, while the quieter modes cover everyday runs.

V-shaped brush that resists hair tangling

The main brush uses a comb-like structure that guides hair straight into the bin instead of winding it around the roller. The side brush works the same way, sparing you the usual scissor session in a home with pets.

LDS laser navigation with multi-floor 3D maps

The rotating laser scans 360° and builds a floor plan on the very first run. Several floors can be stored, and routes are planned row by row without covering the same spot twice.

Zones, virtual walls and schedules in Xiaomi Home

In the app you draw no-go zones and virtual walls around play areas or pet bowls, set a start time and choose separate settings per room. Water flow has three levels, and carpets get four behaviours, including avoidance and vacuum-only.
