I'd love to try the Dysons, probably the one labelled "Absolute"...we have a Kenmore canister and unfortunately (I should say fortunately, depending on how you look at it) it's still working fantastically well. It has always worked very well and sucks big time. But it's a bit inconvenient to have to lug around, plug in and use for quick pick-ups. We've tried so many different variations of those quick dust busters, and either took them back within a week or gave them away after a few months.

We did buy a cordless vacuum for quick pick-ups upstairs in the bedroom area. I forget the brand name, but it's also very good. The battery only lasts about 30 minutes though, which I knew when we bought it, but it had such high reviews anyway, we took a chance. I'm not sorry we bought that, it's perfect for that small area of the house.

Anyway, I can't justify buying a new one, but if I could, would splurge on the Dyson.
