I believe jr.trhodes was talking about the short flexible hose within the contact head. I have the same problem and Dyson told me there are no spare p[arts available. It’s obviously a weak link in the design as it takes a beating and is constantly being flexed. A real shame Dyson doesn’t do more to help it’s customers as the vacuum cleaner is efficient and expensive but one small hose brings it to a halt - or you buy an entire contact head and have to throw the old one away instead of repairing it.
