I got this to see if it would help me keep up with my dogs shedding, because he doesn't seem to stop, and at first it ran all the time, just because there's so much fur, but now that it's been going for about a week, it's keeping up pretty good. Now granted I still have to vacuum, which I knew I'd have to, but it's taking care of quite a bit of it for me. I love that it's self cleaning also, that's even less for me to do, the less the better!
