Bad vacuum cleaner - don't buy it.
After about 10 mins of use the filters clog up. You then have to dismantle, clean, wash and dry parts before re-assembling to enable another 10 mins of vacuuming. Apparently this is a common fault with this vacuum. My mum has one and a friend has one and they both have the same problem.
It's so frustrating, so don't buy it!!!
