Vacuum displays E15; LED indicators show a filter icon, and suction is reduced.

Safety first: Turn off the vacuum and remove the battery. Never operate the vacuum with wet filters installed.

• Remove filters: Take out the pre-motor filter (usually foam or mesh) and the HEPA/post-motor filter.
• Dry cleaning: Gently tap filters over a trash can to remove loose dust. Use a soft brush to clean the filter frame.
• Wash if allowed: If the manual states that the filters are washable, rinse them under cold water until the water runs clear. Do not use detergents. Gently squeeze out excess water.
• Dry completely: Air-dry filters for at least 24 hours until they are completely dry. Reinstall only when no moisture remains.
• Replace if old: If filters are deformed, torn, or heavily stained, replace them with a genuine Roborock Filter Set.
