As any pet owner (I have a cat) knows, even if you own a good vacuum (I have two of our picks, a Miele canister and a cordless Dyson V7), there still always seems to be some pet hair around. So instead of asking what's the best vacuum for pet hair, we asked ourselves something more to the point: What's the best way to keep pet hair to a minimum in your home? Any good vacuum--upright or canister, corded or cordless--will do an excellent job of picking up pet hair, on both hard floors and carpets. We've tested all these styles, using bagfuls of genuine cat and dog hair, and all our picks excelled at the task. The reason you're seeing pet hair around is that pets shed constantly, so no matter how good your vacuum is, you're unlikely to keep up--unless you have a vacuum that can work constantly.
