Beating a dead horse here, but if you've come here BEFORE buying a Dyson vacuum, pat yourself on the back and buy a Shark. Dyson has a deliberately fraudulent support process in which they make cheap parts that break (wheels falling off of heads, for example) and do not provide a way for you to buy replacement parts, trying to force you to buy the new model instead. Be smart, don't buy Dyson. They also promised me support would call me back after my last ridiculous chat session, and of course they didn't. No new story here, just adding to the pile-on in hopes that some readers benefit.

CLARIFICATION: I’ve gotten flamed by some people because they got their warranteed parts replaced. I should have been clearer. After you are out of warranty, they will not sell you replacement parts. You can confirm this on their website, lots of parts like cleaner heads are listed as out of stock. Their support guy, in that same session mentioned above, told me they won’t sell me parts because they are saving them for warranty replacements.
