I foster dogs for two local rescues and at all times I have a minimum of seven dogs in my home. They track in dirt, dust and they shed like crazy. I have had several Kirby vacuums for the last 35 years, and was sold totally on them. I had noticed lots and lots of dust in my house even after cleaning. We vacuum every other day so I thought my carpets were reasonably clean. I bought the Dyson because it was recommended to me by another dog-owner. Talk about happy! I am thrilled to the maximum with this vacuum. It is light weight, easy to maneuver, and boy does it ever pick up the hair and debris in the carpet! I almost died when I saw how much this unit picked up the first time I used it. The canister had to be emptied twice!!! I have 1500 Sq Ft of carpeting in my house, and it was literally overflowing with stuff my Kirby had missed. I put my old vacuum on the curb and am dedicated to this Animal. I highly recommend it to anyone who has animals in their home - it will make much difference in how much you have to dust your furniture. My home is much cleaner since I've been using this Dyson Animal. As I said, It's a beast!
