Thought my carpets were clean and well vacuumed. Brought this Dyson Animal home, and gasped at the amount of pet hair and dust my old vacuum had left behind. EXTREMELY powerful, not noisy; easy to push. Very heavy to carry up stairs, though. So easy to dump the canister- a simple thumb release. Accesories suck the dust from everywhere. Extension rod a bit unwieldy until the hose loosens up a bit (with use). No dust bags. Would buy it again in a minute- best vaccuum i have ever owned. Great for asthma sufferers.
