The vacuum itself is a good product but the head attachment has a design flaw for pet owners. I just blew my second vacuum head and decided to open the second one to find the problem. Apparently my dog's long hair was slowly growing out and squeezing the rotor belt into the side panel. I regularly pull my hair out of the rotor, but those hairs got caught out of sight near the belt. I hope Dyson replaces this nozzle or I'll buy a brand new vacuum.
