I am always confused when i have to buy a new hoover? the market is really full of brands,some friends recommended Dyson DC25 Vacuum Ball cleaner,what do you think about it?

This one really looks unique but i have never heard about it before,i am using Hoover FloorMate SpinScrub 800, H3060,it washs, vacuums and dries all non-carpeted hard surfaces . Seven scrubbing brushes cover a 15-inch cleaning path, and the dual tank design allows you to have separate tanks for clean and dirty water so you don't put dirty water on clean floors.
