S.S.
We bought an upright Dyson animal and just returned it for the Dyson canister animal. Reasons: upright couldn't vacuum under the bed/couch, stairs were a pain - you had to extend a wand with a hose that's too short to do the whole stairs, so you had to hold on to the upright while dealing with the wand. The canister Dyson seems to be a keeper. Also has a nice feature that "hooks onto" the stairs so it doesn't fall off if the wand isn't long enough.
