I underwent a 3 month remodel of most of my downstairs. The contractors tracked all manner of dirt and filth on about 1/3 of the carpet in the master BR that left horrible spots and stains. I even had a guy pouring cement in the slab foundation and he tracked some black stuff (cement off his boots, I think) on the carpet that I was sure would never come up. I was going to have my flooring guy replace the whole carpet completely because I was sure it was ruined. How WRONG I was! Miguel Polo got that up and made the bedroom and LR carpets look BRAND NEW. If he can clean up after contractors, he can clean anything. I will use them again!
Pros: Fast, DRY, Smells good
Cons: Can't think of any
