Hands-free bin emptying, thanks to the auto-empty sealed base

The brush-roll automatically adjusts to carpets and hard floors, actively removing hair as it spins to prevent tangles building up. The mechanism reduces manual cleaning of the brush-head.
Fewer maintenance sessions on the brush-roll make vacuuming quicker for pet owners and long-haired households.
Grab-and-go cleaning, with up to 40 minutes run-time and dock charging
Battery charges while stored on the included UK-plug charging dock, delivering up to 40 minutes run-time in ECO mode when using a non-motorised tool. The main vacuum detaches to a handheld unit with a 0.42L capacity for spot tasks.

❓ Frequently Asked Questions
Q: How often do I need to empty the base?
A: The sealed base can hold dirt and debris for up to 30 days, so emptying is only required after that period depending on usage. Regular checks are sensible in very high-traffic or heavily soiled homes.
Q: How long does the battery last between charges?
A: Up to 40 minutes run-time in ECO mode when using a non-motorised tool, and the vacuum charges while stored on the included UK-plug dock. Actual run-time will depend on power mode and attachments used.
Q: Is it suitable for homes with pets?
A: Yes, the Anti Hair Wrap self-cleaning brush-roll and included Pet Multi-Tool help manage fur, and the sealed base traps fine dust and allergens to reduce airborne particles.
