Champion Chem-Dry II

I initially liked that they were "green," but I would absolutely not recommend them for pet stains. When the technician was leaving, I could still see the cat pee stains under a black light. The guy told me this was not a problem, that the cat couldn't smell them. In fact he could, and he urinated again in the same area. The manager, Jorge, tried to stonewall me when I complained, saying that their guarantee of satisfaction meant only that people wouldn't be able to smell the cat pee, not cats. (Aside from this not being what I had been told on the phone and in person, it was ridiculous -- I wasn't really worried about the humans in my life peeing on the carpet.) After I read them a section of their website -- which they have since rewritten -- I talked them into coming back for a touch-up on the top carpet. But the treatment still did not work. Only because I have covered over the carpet with another rug has the cat not returned to the scene of the crime. (And I could have done that without spending money at Champion Chem Dry-II. Total money down the drain.)
