Xiaomi publishes separate schedules for the Robot Vacuum X20 Max and the UK Robot Vacuum X20+. Their care frequencies are similar in some rows, but they are not one interchangeable schedule. Check the current X20 Max FAQ or UK X20+ schedule before relying on an updated schedule.
X20 Max robot and Omni station
The X20 Max FAQ recommends cleaning the filter, main brush, and side brush every two weeks. It gives 3–6 months for filter replacement, 6–12 months for the main brush, 3–6 months for the side brush, and 1–3 months for mop pads. Listed robot sensors and contacts and the caster are cleaned monthly.
For its Omni station, clean the clean-water tank every two weeks, the dirty-water tank after each use, and the washboard every 1–2 weeks. The disposable bag has an about-2.5-month replacement example depending on use; station surfaces without a fixed interval are cleaned as needed.
The FAQ permits clean-water rinsing of the dust compartment when needed. Remove the filter first, do not use detergent, and do not brush or finger-clean the filter. Avoid frequent rinsing and dry the parts fully before reinstalling. After cleaning the washboard, seat the water pipe in its groove and do not tilt the station.
UK X20+ robot and Omni station
The UK X20+ page lists two-week care for its filter, clean-water tank, main brush, and side brush. The dirty-water tank is cleaned after use; the cleaning tray is cleaned every 1–2 weeks. It gives replacement examples of 3–6 months for the filter, side brush, and mop pad, 6–12 months for the main brush, and about 2.5 months for the disposable bag depending on use. Listed robot and station sensors, contacts, vents, and surfaces are cleaned monthly.
That page is a schedule, not a complete removal or drying procedure. The X20+ mop-pad replacement example differs from the X20 Max schedule. Use the exact unit’s manual for approved liquids, disassembly, and drying time; do not transfer X20 Max cleaning steps to the X20+.
