I have had excellent service calling Dyson. Our vaccuum had a few problems and they sent replacement parts. The part arrived fairly quickly, I must say they were excellent to talk to! I recommend calling them.
BTW, the Dyson we have (purple animal) is not all that awesome. While it does a good job and has a strong suction, it is not able to get close to the baseboards or corners. Personally I don't like the attachments and I use an old attachment from my Windtunnel to do our stairs.
But like I said their customer service is outstanding. We had filter problems and then the seal on the main suction cylinder was not right. We ended up getting free parts for almost the whole thing. Very happy that way.
