Xiaomi Robot Vacuum S40 Pro

Xiaomi Robot Vacuum S40 Pro is built for households that want a single device to handle both vacuuming and mopping with minimal daily intervention. It combines powerful 15000Pa suction with a dual spinning mop system that mimics the motion of hand-wiping. The standout feature is its pair of extendable mechanical arms, which push the side brush and mop pad outward to reach corners and edges within millimeters of the wall. With a 5200mAh battery, a 430mL dustbin, and a 310mL water tank, it can cover up to 180 square meters in a single run. Navigation relies on LDS laser mapping combined with a 129° structured-light sensor for obstacle avoidance, while a dual anti-tangle system on the brushes reduces the amount of manual maintenance needed. Key Features : 15000Pa Powerful Suction: Powered by a proprietary high-speed fan with aerospace-grade aluminum-magnesium alloy blades, the S40 Pro achieves a 99% large particle collection rate on hard floors. This level of suction is noticeably stronger than the standard S40's 10000Pa, making it effective against pet hair, fine dust, and everyday debris. Extendable Dual Mechanical Arms for Edge Cleaning: When the vacuum detects a corner, the side brush extends outward to reach a 0mm distance from the edge, while the mop pad extends to clean within 1mm of the wall. Together, these arms achieve 100% coverage of corners and edges without needing a second pass. An anti-collision mop pad tray also protects furniture edges during operation. Dual Spinning Mop Pads at 180rpm: The two mop pads rotate to replicate a hand-wiping motion for removing stubborn dirt and stains. The water tank offers 3 adjustable flow levels, letting you control how wet the mop pads stay depending on the floor type, which helps minimize water marks. Dual Anti-Tangle System: The Y-shaped main roller brush uses bristles designed to block, detangle, and gather hair before it's pulled into the dust box by the 15000Pa suction. The side brush is also anti-tangle, and sealed end caps on the main brush prevent hair from being pulled in from the sides — reducing the frequency of manual cleaning. Cleans Up to 180m² in One Run: The 5200mAh battery, combined with a 430mL dustbin and 310mL water tank, allows the S40 Pro to handle larger homes without needing to stop for water refills or frequent dustbin emptying. Smart Carpet Detection with Automatic Mop Lift: Ultrasonic sensors detect carpets and automatically raise the mop pads by up to 10mm to keep them dry. Four customizable carpet modes are available: clean carpet first, carpet avoidance, carpet crossing, or ignore carpets entirely — all adjustable per room through the app. LDS Laser Navigation with 129° Structured-Light Obstacle Avoidance: A full 360° scan builds an accurate map of the home quickly, and the layout is remembered to avoid repeated mapping. The wide-angle structured-light sensor helps detect low-lying obstacles and navigate precisely, even in low-light conditions. Climbs Obstacles Up to 20mm: A smart floating main brush cover automatically adjusts to different floor heights, allowing the vacuum to cross thresholds and low obstacles smoothly without getting stuck. Full Control via Xiaomi Home App with Voice Assistant Support: Schedule and start cleaning remotely, set no-go zones, target specific furniture areas (such as around a dining table or pet litter box), monitor remaining cleaning time, and review a cleaning report after each run. The vacuum also supports voice commands through Amazon Alexa and Google Assistant.
