After several months of using this I get about 1/2 to 2 canisters worth of hair out every other day. My allergies and my dog's allergies have subsided tremendously! My house has a cement slab as a floor so I need the carpet to keep the house warm. Thank goodness the Dyson Animal can keep my carpet free of debris and hair.
I love that the canister keeps the dust and odor confined. With my old Kirby you could see the dust floating around (even with a HEPA bag) and smell the doggy odor. The Dyson Animal vacuum is terrific and the ball feature makes it so easy to maneuver!!!
