Probably somewhere in all the comments most of mine are addressed, but here goes:
I have a yellow DC33 I bought at Sam's a few years ago, mostly based on the hype and my brother (an engineer) recommending Dyson. Right out of the box I had an issue because we have rugs, not carpets - the thing screams like crazy when the beater bar becomes trapped by suction or material. The only way to stop it is pick up the vacuum and break the suction. Dyson did, in all fairness, give me some adjustments to the head, but they didn't help much.
I also do not like the cord (too much memory from wrapping) or the hose (drags the machine around when you extend it). And the "your hands never touch the dirt" is a great line, but cleaning out the canister does require digging around for stuff that gets pulled up into it.
Anyway, this might be a good unit for carpets or homes with pets, but I wouldn't buy another, especially at the regular price.
