Usage

Self-cleaning: Place the vacuum on the base, ensure the clean water tank has at least 200ml of water and the dirty water tank is empty. Press and hold the On/Off button for 5 seconds. The cycle lasts 70 seconds.
Filters and tanks: Empty and rinse both tanks after every use. Remove the fine filter from the dirty water tank lid and rinse under running water. Allow all parts to dry completely before reassembly.
Turbo brush: Remove the cover and roller. Use the cleaning brush (which includes a folding blade) to cut away tangled hair and debris. Wash the roller in warm water and let it dry thoroughly.
