The Xiaomi Robot Vacuum S40 Pro is a comprehensive, feature-rich robot vacuum and mop that brings together powerful 15,000Pa fan blower suction, dual rotating mop pads with intelligent 10mm carpet lifting, dual extended mechanical arms for superior edge and corner cleaning and LDS laser navigation in a single autonomous cleaning solution — delivering whole-home cleanliness for both dry vacuuming and wet mopping in one pass without requiring a separate mop or manual floor washing at any stage. Powered by a flagship proprietary high-speed fan blower with aerospace-grade aluminium-magnesium alloy fan blades, the S40 Pro generates 15,000Pa of suction that efficiently removes hair, fine dust, large particles and daily dirt from every floor surface with a confirmed 99% large particle collection rate on hard floors in standard vacuuming mode. The anti-tangle design built into both the main brush and the side brush actively reduces hair entanglement during cleaning — preventing the brush wrapping that makes conventional robot vacuum maintenance time-consuming and ensures the S40 Pro maintains consistent cleaning performance across every session without manual brush clearing between uses.

The dual extended mechanical arms — a side brush swing and mop swing design working together — are the engineering innovation that gives the S40 Pro its superior edge-cleaning performance compared to conventional fixed-brush robot vacuums. The side brush swings outward to reach further into corners and along skirting boards, sweeping debris directly into the robot's suction path, while the mop swing extends the mop pads outward to cover floor area right to the edge of walls and furniture legs — ensuring that the zones closest to obstacles and boundaries receive the same thorough cleaning as open floor areas rather than being left with the visible dust lines that fixed-width vacuums leave behind. The dual rotating mop pads provide powerful scrubbing action on hard floors with the kind of rotary cleaning force that passive mop pads cannot replicate — lifting and removing stubborn dried-on residue, footprints and surface stains that simple dragging mop pads leave behind. The 290ml water tank with smart water replenishment control delivers consistent, steady moisture to the rotating pads throughout the entire cleaning session, ensuring wet mopping performance remains effective from the first room to the last rather than running dry mid-session.

Intelligent mop pad lifting raises the mop pads up to 10mm automatically when the S40 Pro detects a carpet or rug — keeping the carpet pile completely dry during vacuuming passes without requiring you to manually set exclusion zones or remove rugs from the robot's path. For carpets with pile heights exceeding 5mm or where extra moisture protection is needed, Bypass Carpet mode diverts the robot around carpeted areas entirely. The LDS laser navigation system maps your home with high precision — using a single-line laser combined with collision sensors to plan optimal cleaning paths, detect obstacles and avoid falls on stairs and elevated surfaces. The complete map is saved through the Xiaomi Home App, where you can set restricted zones, define no-go areas, configure custom cleaning programmes for individual rooms, set cleaning schedules and monitor the robot's cleaning progress in real time from anywhere. The S40 Pro automatically returns to its charging dock when the battery is low or when the cleaning session is complete, docking precisely every time without manual guidance. The 5200mAh lithium-ion battery supports up to 120 minutes of continuous operation in standard vacuuming and mopping mode — sufficient to clean most homes on a single charge. The 400ml dust compartment provides generous capacity for extended cleaning sessions before requiring emptying. Compatible with Android 9.0 and above and iOS 14.0 and above through the Xiaomi Home App, the Xiaomi Robot Vacuum S40 Pro is the most complete and most thoughtfully engineered robot vacuum Xiaomi offers at this price
