Robot Vacuum Cleaner Xiaomi X20 Max

The Xiaomi X20 Max is an all-in-one robot vacuum cleaner with an auto mop-pad washing base station that also performs hot-air drying and dust collection. The unit integrates LDS laser navigation and a high-capacity battery to cover extensive floor areas while offering adjustable suction and water flow for combined vacuuming and mopping tasks.

Advantages

The base station automatically soaks, spins and rinses the dual rotary mop pads, then dries them with hot air to reduce mould and odours. Automatic dust collection transfers debris into a 2.5 L dust bag to minimize manual emptying. A 4 L clean water tank and a 3.8 L dirty water tank allow an actual single-run mopping area up to 120 m². The robot uses 360° LDS laser mapping with 120° structured-light and edge sensors for precise obstacle avoidance, and it supports carpet recognition with automatic mop pad lifting and Carpet Boost suction.

Suitable for

• Homes requiring combined vacuuming and wet mopping
• Large apartments or houses up to about 120 m² per run
• Households that prefer hands-free maintenance with auto dust collection
• Mixed-floor homes with carpets and hard floors requiring automatic carpet detection

How to use

Place the base station on a flat surface with enough clearance for docking. Fill the clean water tank and ensure the dust bag is installed. Use the Mi Home / Xiaomi Home app to start cleaning, schedule runs, and set restricted areas. The robot will vacuum and mop according to the selected mode; when docked, the base station washes and spins the mop pads, collects dust into the bag and performs hot-air drying. For carpeted areas, enable Carpet Boost to lift the mop pads and increase suction automatically.

Usage recommendations

Maintain the detachable cleaning tray and mop pads by cleaning them regularly; replace the dust bag according to usage (the 2.5 L bag typically needs emptying or replacement about every 75 days under average use). Keep furniture edges clear and update maps in the app after rearranging rooms for optimal navigation.
