This was purchased as a replacement for an older upright from a different manufacturer. The older unit was never particularly reliable, and had become even less so in recent years. I'd had a maid service in to clean at one point and saw one of them had a Zing and watched her use it. Small, portable, and (as I know now) powerful. It was precisely what I wanted. We have two cats, and keeping up with their shedding is always a chore, but the Zing has made it very easy and I can't recommend it enough. When I went shopping for a replacement this was my first choice, and then when I saw that Bissell runs a pet foundation, I knew my mind was made up. Thanks for making quality products and helping to save animals!
