Auto-Empty System

When docked, the vacuum automatically empties its dust cup into the 2L base, sealing away dirt, dust, allergens, and odors for up to 45 days. This eliminates the need for manual emptying after every clean.

Maintenance

Emptying the Auto-Empty Base

The Auto-Empty base can hold up to 45 days of dirt and debris. When the base is full, the indicator light will signal it's time to empty. Simply remove the dust bin from the base and dispose of the contents.

Cleaning Filters

Regularly clean the filters to maintain optimal suction performance. Refer to the filter locations in your vacuum. Rinse foam and felt filters with water and allow them to air dry completely before reinserting. The HEPA filter should also be cleaned periodically according to instructions.

Brushroll Maintenance

Inspect the brushrolls for any hair wrap or debris. Use scissors to carefully cut away any tangled hair. Ensure the brushrolls spin freely.
