I had a Dyson and it was an overpriced POS IMHO. I bought a Miele canister (thing is on rollers, long hose, want with attachments, has a bag) great fucking vacuum! Quiet, sucks like a chick you would take to Waffle House and she would be happy, bags were kinda cool. Then I moved, in to a house with wood floors throughout, everywhere. Miele became a PITA, bought a Shark because it had a wood floor brush (and a carpet one, you can switch them), damn thing works great! Small canister on mine, but it works great.
ETA: Mine is just a hard floor vacuum, it doesn't have a wand or attachments (I still have the Miele for that)... My previous Dyson wouldn't suck up a penny, but the worst part is all the attachment clips kept breaking and the hose was so stiff it was a nightmare.
