Filter Cleaning and Maintenance
To maintain optimal suction power and filter efficiency, regular cleaning is recommended. Clean the filters at least once a week, or more frequently with heavy use.
- Remove Filters: Follow steps 1-3 from the "Filter Replacement Instructions" to remove both the pre-filter and the high-efficiency filter from the dust bin.
- Wash Filters: Rinse both filters under cold running water until the water runs clear. Do not use hot water or detergents.
- Dry Completely: Allow the filters to air dry completely for at least 24 hours before reinserting them into the vacuum cleaner. Ensure they are completely dry to prevent damage to the vacuum and mold growth. Do not expose to direct sunlight or use a dryer.
- Reinstall Filters: Once completely dry, reinsert the filters into the dust bin and reassemble the vacuum as described in the replacement instructions.
