I previously had a Bissell Proheat rug cleaner, but it was so big and heavy, I donated it and purchased the PowerDash Pet machine. I used it today on old coffee spills and Cat stains (I have 2 cats, one a very long haired cat). I was amazed at how lightweight and efficient this machine is! My cats LONG hair did not jam it or wrap around the roller, but stayed on the bristles where I could easily pick it off. I am an older woman with not much strength, so this machine is a wonder to me! Thank you!
