As a owner of Austrian Shepard I have to deal with a lot of dog hair everywhere! Normally i have to take the covers off of our couch just to clean it because the suction on our vacuum would never pick up the hair. Now with the special pet hair brush on the Hoover Windtunnel 3 High Performance Pet Bagless Upright I can easily get all the dog hair up without having to take apart my couch. I was shocked to see how much dog hair was in our carpets. I had just vacuumed with our old vacuum the night before but the canister was full of dog hair after re-vacuuming with the Hoover - WindTunnel® 3 High Performance Pet vacuum. I love the super long cord that allows you to vacuum multi able rooms without having to unplug your vacuum.
