I have a Hoover Windtunnel Bagless and it's great. You have to replace the main filter about once a year. It cost around 170 and it was rated 2 or 3 on Consumer Reports list last year. I have a dog and it gets up the hair and dander really well. The only down side of the bagless is disposing of the contents of the canister, it's kind of messy, but any bagless will be.
