I've done it. The uncloggable vacuum that never loses suction, has lost suction. Granted, I don't think Dyson considers what I vacuum a normal household. I have two mini schnauzers that like to tear up stuffed animals, my house is constantly covered in cotton. I pick most of it up by hand, but occasionally I'll vacuum some of it up with the Dyson. Therein lies the problem, cotton clogs. I think I'll have to have the dogs start up some manual labor to earn enough money for a new vacuum. Time to strap a shovel to their necks so they can plow the field.
