I recently tried out the Pledge Fabric Sweeper through bzzagent. Bottom line: it works fairly well but not as good as the old fashioned vacuum. You use short strokes and brush the sweeper over the hairy fabric. It then collects the fur inside the sweeper, and when it's full you throw it away. It costs $4.99 and there are coupons out there right now. The package says it's the equivilant to 145 lint roller sheets. It is nice not to have to deal w/ peeling the roller sheets off--and they get filled up so quickly. On really hairy areas, though, it did leave a little fur behind.
