I owned one of the first Dyson's which I bought refurbished on Woot. I didn't have any problems with it. Several years later, I boubht another refurbished Dyson and it was terrible. I couldn't "return" it and couldn't get it repaired--there was something creating a very loud noise every time I pulled the handle down to vacuum. I gave it to my brother in law, who fixed it. I'm in need of a new vacuum once again, and I'm tempted but reluctant. With all the money I've spent on vacuums in the last few years, I could have a brand new Miele.
