After nearly 10 years, our Dyson DC07 Animal is going strong, although it is in need of a good cleaning itself, and a new hose (I poked a hole in the hose by accident and have duct-taped it shut - the repair works okay, not great). It has never lost suction, and continues to pick up the massive amounts of dog hair that my two large dogs deposit throughout the house. It works excellent on tile and carpet, and I have no trouble vacumming the stairs, either. I love my Dyson, and because of that I want to get some of the newer technology - the Ball, the quick-draw hose, slim suction head, etc. These have been my (minor) complaints with the Dyson from the beginning, so I am excited to see the improvements Dyson has made over the years. I will be giving my beloved DC07 to a friend or family member, and upgrading to the DC25 Multi-Floor. I am super-excited!
