I have always loved a canister vacuum. Have a Kenmore now and it's O.K., but had decided that when necessary I will bite the bullet and get a Dyson. Son just recently did all of the online research on the Dyson and Shark and ended up going with the Shark. He thinks that it's great. We'll see how long it lasts. If he continues to have good things to say about it, I might get one.
