FAQs
How often do I need to empty the auto-empty base?
The auto-empty base is designed to hold dirt and debris for up to 30 days, depending on your usage and the amount of dirt collected. An indicator will typically signal when it's time to empty the base.
What is the actual run-time of the vacuum?
The vacuum provides up to 40 minutes of run-time when used in ECO power mode with a non-motorised tool. This duration will be shorter when using higher power settings or motorised attachments.
Is this vacuum suitable for pet hair?
Yes, absolutely. The Anti Hair Wrap self-cleaning brush-roll is specifically designed to handle pet hair effectively, preventing it from tangling around the brush-roll as you clean.
Can I use this vacuum on both carpets and hard floors?
Yes, the Anti Hair Wrap brush-roll automatically adjusts to clean both carpets and hard floors efficiently, making it versatile for various surfaces in your home.
How heavy is the Shark Clean & Empty Cordless Vacuum?
The vacuum unit itself weighs 2.7kg (approximately 5.95 lbs), making it a lightweight option that is easy to maneuver and lift for extended cleaning tasks.
What tools are included with the vacuum?
The vacuum typically includes a Motorised Hand tool, Crevice tool, Multi Surface tool, and an Anti-Allergen Brush, alongside the main vacuum unit and the auto-empty charging dock.
How does the 'seals away fine dust' feature benefit me?
The sealed system in the auto-empty base traps up to 99.9% of dust and allergens down to 0.3 microns. This significantly reduces the amount of dust released back into your home environment, which is especially beneficial for those with allergies or asthma.
Troubleshooting
Vacuum is not turning on or charging.
Ensure the charging dock is properly plugged into a live UK power outlet. Verify that the vacuum is correctly seated on the charging dock and the charging lights are illuminated. Check if the battery pack is securely inserted into the vacuum. If issues persist, try a different power outlet.
Poor suction or debris not being picked up effectively.
Check the dust cup for blockages or if it's full. Inspect the floorhead and wand for any obstructions. Ensure the filters are clean and properly installed; rinse and air dry if necessary. Make sure the Anti Hair Wrap brush-roll is free from any large debris.
Auto-empty system is not activating or emptying properly.
Ensure the vacuum is correctly docked onto the auto-empty base. Check if the base's collection bin is full and needs emptying. Verify that there are no obstructions in the vacuum's dust cup or the base's intake port. Close the vacuum's dust cup lid completely after manual emptying to allow the system to engage.
Run-time is shorter than expected.
The 40-minute run-time is achieved in ECO mode with non-motorised tools. Using the vacuum in higher power modes, with motorised tools (like the main floorhead), or on thick carpets will reduce battery life. Ensure the battery is fully charged before use.

Care & Maintenance
- Emptying the Auto-Empty Base: The base holds dirt for up to 30 days. When the indicator light signals, or the base appears full, unlatch the top, remove the bag (if applicable) or container, and dispose of the contents responsibly. Info needed: [Confirm if base uses bags or bagless container to empty and specific instructions for emptying the base.]
- Cleaning Filters: Regularly check and clean the filters (pre-motor and post-motor, if present) to maintain optimal suction. Tap loose dirt from the pre-motor filter and rinse it with water when necessary. Allow filters to air dry completely for at least 24 hours before reinserting.
- Brush-roll Maintenance: While the Anti Hair Wrap technology largely prevents tangles, occasionally check the brush-roll for any stubborn debris or blockages. Remove any obstructions manually.
- Exterior Cleaning: Wipe the exterior of the vacuum and the charging dock with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
