I hated my Dyson and sold it. Maybe I would have liked the one with the ball better but the one I had (the Animal) was heavy and hard to negotiate into small areas. It would probably be great for really large rooms/areas - but that's not what I have. I had wall to wall carpet when I bought it and still didn't like it. Now I only have a couple of small area rugs and I bought a cheap tank type at Sears for the dust bunnies. It is lightweight and easy to haul from room to room.
