Xiaomi Robot Vacuum S40 Pro
The Xiaomi Robot Vacuum S40 Pro combines strong suction, rotary mopping and intelligent navigation to handle everyday floor cleaning throughout the home.
Dual extending mechanical arms improve coverage beside walls and in corners, while smart carpet recognition and structured-light obstacle avoidance support more adaptable cleaning.
Key Features
-
15,000Pa suction: Removes hair, fine dust, large particles and everyday dirt from hard floors and carpets.
-
Dual extending arms: The side brush and mop pad extend dynamically for closer edge and corner cleaning.
-
Rotary mopping: Dual mop pads rotate at approximately 180rpm, with three adjustable water-flow levels.
-
Dual anti-tangle design: The Y-shaped main brush and anti-tangle side brush help reduce wrapped hair.
-
Smart carpet cleaning: Ultrasonic detection raises the mop pads by up to 10mm and supports four carpet-cleaning preferences.
-
Structured-light obstacle avoidance: A 129-degree wide field of view helps detect low obstacles, including in low light.

Threshold climbing: Can cross obstacles up to 20mm high under Xiaomi test conditions.
Extended Cleaning Coverage
The extendable side brush can reach corners with zero-distance edge contact under Xiaomi laboratory conditions, while the outward-moving mop pad cleans as close as 1mm to walls. An anti-collision mop tray helps protect furniture edges.
Battery and Capacity
A 5200mAh nominal-capacity battery supports vacuuming and mopping across up to 180m² under Xiaomi test conditions. The robot includes a 430ml dust compartment and a 310ml water tank.
