Maintenance

Emptying the Dust Cup (Auto-Empty Base)

The auto-empty dock automatically empties the vacuum's dust cup and stores debris for up to 30 days, providing hands-free convenience.

• After each cleaning session, dock the vacuum onto the auto-empty base.
• The base will automatically activate to suction debris from the vacuum's dust cup into its sealed container.
• When the base's container is full (approximately every 30 days, depending on usage), simply remove and empty it into a waste bin.

Cleaning Filters

Regularly clean the filters to maintain optimal suction power. The Shark PowerLite features sealed HEPA filtration.

• Pre-Motor Filters: Rinse with water monthly. Allow to air dry completely for at least 24 hours before reinstalling.
• Post-Motor HEPA Filter: Rinse with water annually. Allow to air dry completely for at least 24 hours before reinstalling.

Refer to the filter access points on your handheld unit for removal and reinstallation instructions.

Maintaining the Brush-roll

The PowerFins brush-roll is designed with anti-hair wrap technology to minimize hair tangles. Periodically inspect the brush-roll for any debris.

• Turn off the vacuum and disconnect it from the power source.
• Access the brush-roll by opening the cover on the floor nozzle.
• Carefully remove any string, hair, or debris that may have wrapped around the brush-roll.
• Ensure the brush-roll is free of obstructions before reassembling.

Troubleshooting

If you encounter any issues with your vacuum, refer to the following common problems and solutions.

• Vacuum not turning on: Ensure the battery is fully charged and correctly inserted. Check if the power button is pressed firmly.
• Loss of suction: Check if the dust cup is full or if the auto-empty base needs emptying. Clean all filters as per maintenance instructions. Check for blockages in the nozzle, wand, or hose.
• Brush-roll not spinning: Ensure the vacuum is in a mode that activates the brush-roll (AUTO or BOOST). Check for obstructions in the brush-roll area and clear any tangled hair or debris.
• Vacuum not charging: Ensure the vacuum is correctly docked on the auto-empty base and the base is plugged into a working power outlet. Check for any debris preventing proper contact.
• Auto-empty base not emptying: Ensure the vacuum is fully seated on the dock. Check if the base's debris container is full or if there are any blockages in the emptying path.
