As others have stated, Dyson. I've got a DC28 Animal and that thing is a beast. It is amazing the shi* it will pull up. I won't pay full price, but there are deals to be had. About 2 years into ownership the beater brush seized. Probably just as much our fault for not cleaning it when it was full of hair as anything because it picks it up so quickly. I had to drop it off at a repair shop ~30 miles away and wait about a week, but they replaced the entire head free of charge. I'll buy another Dyson when this one dies.
