We have a big-beast Dyson, a hand-held Dyson and a Dyson V6 rechargeable job. They are all brilliant - when they work. Thankfully, during our tenure of these machines there's always been a five-year warranty. We have had to call on it a number of times. I won't regale you with the multifarious problems we've had. When they work well they're brilliant. But there are still issues. It's hard to empty the dust without breathing it in. Emptying leaves the outside parts dirty. Filters are hard to wash properly. On one occasion I had to seek advice on filter cleaning from their helpline. Hoses break, tubes get clogged, non-return flaps sieze up, mains cords break inside the machine. They're good but they haven't solved the problem of everyday users actually using the machines.
