I have a new Jack Russel Puppy as well as some furbaby kitties, so the training messes and the house smell in gener can get pretty potent. I have tried so many products, so many machines for tiles, carpeting and furniture. I will admit, I was a little apprehensive about Petlab, I thought "just another cleaning gimmick"....but I was also desperate. Well, my floors have never looked, felt and smelt cleaner! My carpets, although I was washing them on a regular basis, came up amazingly, ans the smell lasted for much longer than with the products I has been using. In short, I am amazed, impressed and will continue to use and recomment Petlab to any houshold with animals!
