My household consists of two cats and two toddlers (who make messes on par with pets), so I was thrilled to try out this Pet Stain Eraser, which I received to try as a part of the Stellar Product Testing Panel. Our house has carpet, tile and wood, and the cats don't seem to have a preference on where they make messes. Testing out this product was so easy, it went from in the box to lifting stains in under 2 minutes. It was so simple to set up and very intuitive to use, and very very satisfying to watch the stains be sucked up into the vacuum. I love that I can take the cleaner anywhere in the house (and on the stairs!) easily since it's cordless, and can maneuver it into tight places. We had some very deep set stains that the product really got rid of - this product has allowed us to delay replacing our carpet!
