Hi , there are only two reasons why you loose cuction on your dyson ,either it has a blockage in the system .or one of the pipes is split, check that brushes are rotating first,if they are this means your belt is ok, then it is one of the reasons I stated .

I've had my Dyson cleaner for 10 years - and thought I should have it serviced - If I can just say almost every part has been replaced for £65 would highly recommend - I got on to the official Dyson website and booked my service through them, they arranged for a local engineer to do the service and he was a real expert - looks like I'll get another 10 years out of it
