A deeper clean for your peace of mind
7 major flagship improvements
One machine to handle your entire home floor cleaning
Dual extended mechanical arms with millimetre-level edge cleaning
15000Pa powerful suction fan blower
Main and side brushes with anti-tangle technology
Clean a 180m² home in one go
129° ultra-wide-angle structured light for smart obstacle avoidance
Smart carpet cleaning
360° scanning for automated route planning
Deeper cleaning of dust in corners
Extendable brushing and mopping arms for precise edge cleaning
Dual mechanical arms dynamically extend and retract the side brush and mop pad to effectively clean along edges and in corners, for wider edge coverage and more efficient cleaning.
The side brush extends and retracts flexibly as needed
When a corner is detected, the side brush actively extends to achieve zero-distance edge cleaning for a deeper clean.
0mm* Distance from corners
100%* Coverage of edges and corners
Outward, flexible mop pad extension delivers millimetre-level edge cleaning
The vacuum automatically extends the mop pad to clean along walls and around obstacles, reaching as close as 1mm* for more efficient edge cleaning.
15,000Pa powerful suction fan blower* eliminates stubborn dust efficiently
Equipped with a flagship proprietary high-speed fan and aerospace-grade aluminium-magnesium alloy fan blades, the vacuum delivers enhanced cleaning performance, efficiently removing hair, fine dust and daily dirt from floors.
99%
Large particle collection rate*
*15,000Pa powerful suction fan blower: The suction of the fan blower was measured to be up to 15000Pa using a vacuum gauge with a 0–35kPa measurement range and 0.01kPa precision at the inlet of a fully charged robot vacuum. Data comes from Xiaomi Internal Labs. Results may vary slightly depending on different testing environments.
*99% large particle collection rate: Data comes from Xiaomi Internal Labs. The S40 Pro achieves a 99% collection rate for large particles on hard floors when operated in standard vacuuming mode. Actual results may vary depending on environment and usage scenario. Please refer to the actual experience.
Dual-mop pad rotary cleaning for high-efficiency dirt removal
The vacuum simulates a hand-wiping motion to effectively remove dirt from floors. Its water tank features adjustable flow, ensuring the mop pads stay optimally wet for deep cleaning with minimal water stains.
Dual anti-tangle system for the whole vacuum means less hassle for you
The innovative Y-shaped anti-tangle roller brush with bristles and an anti-tangle side brush provide a safe and efficient solution to hair entanglement so less maintenance is required overall.
Clean a 180m² home in one go without needing to worry about battery life or running out of water
Equipped with a 5200mAh* large-capacity battery, a single charge powers vacuuming and mopping across an area of up to 180m²*. Featuring a 310mL water tank and a 430mL large dustbin, it ensures continuous water supply for consistently wet mopping and efficient cleaning.
430mL dust box capacity Just empty it on weekends
310mL water tank volume No need for frequent refills
Large 5200mAh battery Clean large homes in one go
*5200mAh is the nominal battery capacity.
*180m²: Data comes from Xiaomi Internal Labs. In an open environment under routine maintenance mode, at quiet suction level and level 1 water flow, with a full water tank and vacuum set to vacuuming & mopping mode, the cleaned area recorded on Xiaomi Home app was no less than 180m². Actual cleaning area may vary depending on home environment and usage habits. Please refer to the actual dimensions.
Nimble obstacle avoidance
The smart carpet-recognition system automatically lifts mop pads to keep carpets dry
Equipped with ultrasonic sensors, the vacuum automatically lifts the mop pads by 10mm* upon detecting carpets to prevent them from getting wet. At the same time, you can enable automatic carpet boost to powerfully remove dust embedded deep within carpet fibres.
*10mm: Data comes from Xiaomi Internal Labs. The mop pads can automatically raise up to 10mm. For carpets with pile heights over 5mm or for extra moisture protection, it is recommended to use "Bypass Carpet" mode. Actual experience may vary depending on the environment and usage. Please refer to actual performance.
129° wide-angle laser scanning is precise to the millimetre to avoid getting stuck
Equipped with a wide-area structured light obstacle avoidance system, its 129° ultra-wide field of view allows the vacuum to detect low-lying obstacles. It navigates precisely and avoids collisions with ease, even in low-light environments.
*Before the vacuum maps your space for the first time, it is recommended to clear obstacles to ensure the best user experience. Obstacle avoidance performance may vary depending on your home environment. Please refer to the actual usage experience.
20mm obstacle-climbing* capability
Easily cross thresholds and continue cleaning
Equipped with a smart floating main brush cover that automatically adapts to varying floor heights and a durable brushless motor, the vacuum easily climbs over obstacles up to 20mm high. These features reduce the risk of collisions and getting stuck, ensuring smooth and efficient cleaning.
*20mm obstacle climbing: Data comes from Xiaomi Internal Labs. Under laboratory testing conditions, the vacuum was tested on a platform with a 20mm height difference to verify its climbing ability in different operating modes.
Efficient autonomous cleaning
LDS laser navigation with 360° scanning for quick mapping
Featuring cutting-edge LDS laser navigation, the vacuum performs a 360° scan of your home, quickly creating an accurate map. It remembers your layout for seamless cleaning without repeated scans.
Automatically plans cleaning routes using comprehensive S-curve coverage
Every cleaning step is accounted for, allowing the vacuum to operate normally under both low and bright lighting conditions.
Supports 4 cleaning modes
The four cleaning modes cater to multiple home cleaning scenarios with ease, for a deeper clean every time.
