Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your robot vacuum.
1. Emptying the Dust Bin
After each cleaning cycle, or when the dust bin is full, remove and empty it. Tap out any loose debris and wipe the interior with a dry cloth.
2. Cleaning Filters
The HEPA filter should be cleaned regularly. Gently tap the filter to remove dust. Replace the HEPA filter every 3-6 months, or as needed, to maintain suction power.
3. Cleaning Brushes
Remove the main brush and side brushes. Use the provided cleaning tool to cut and remove any tangled hair or debris. Ensure the brushes spin freely after cleaning.
4. Water Tank and Mop Pad Maintenance
After mopping, empty any remaining water from the tank. Remove and clean the mop pad. It can be hand-washed or machine-washed. Allow both the tank and pad to air dry completely before reattaching.
