This is an excellent machine! We couldn't believe just how much it picked up! So much lighter than the industrial ones you rent at the grocery stores and so worth it. We bought an older home recently and our kids are allergic to cats and dust/mold/pollen. We were aware that the previous owner had a cat so we wanted to make sure that everything was thoroughly cleaned before our family moved in. After using the Bissell on the carpets, we are happy to report that there have been NO allergic reactions at all. Clean carpets, clean house, Happy Family! Thank you Bissell!
