I have been complaining to Dyson for 20 years now about how difficult it is to clean the tiny wheels. Why do they not simply make them removable. With 2 dogs and a cat all long haired the wheels must be cleaned every single vacuum. 20 min to vacuum and 20 min to clean those darn wheels. Anyone have a better solution than scrapping away at it with a sharp knife. I love my Dyson and the only thing that would make me buy another brand would be those awful tiny wheels.
