I have had two Dyson vacs, the first one dc01 was Ok, but eventually gave up the ghost 7 months ago so I've bought one of the new rollerball vacs, and I wish I hadn't. On the plus side it is great picking up hair etc, almost picks up the floorboards, and it is light to carry. I have the smaller one so I have to empty the container more often, and the hose for the staircase isn't long enough. The problem is that it is a carpet vac and a wood floor vac and when I change the beater bar (rollerbrush) to stop to use on a wooden floor I can't restart the brush again without resetting it, this time I can't get the roller brush to go at all, and I'm having to phone the engineer to have it fixed (5year parts and guarantee) I've only had it almost 7 months and I have a feeling this is going to be an ongoing problem with it, It wasn't cheap and I a bit cheesed off with it. A bit of a Mickey Mouse machine this one.
