I used Stanley Steamer in Idaho and they were OK! They were the only cleaner in our town! We called the McKinney Frisco Allen Stanley Steamer to our home and they not only left the carpet soaking wet, it was full of very strong soap! They pressured me into tile cleaning and I couldnt even tell they did anything!
I called didn't call back to complain because frankly the one man was creepy and I didn't feel safe with him leering at me! I had to call another carpet cleaner to extract the water from the carpet, and they showed me all the dirt and soap Stanley Steamer left behind!
Word of warning: Don't get fooled by all of their self written reviews, every single reviewer on Yahoo only reviewed 1 company, Stanley Steamer! I was told by the professional carpet cleaner who fixed their mess, if I had left that dirty water on my carpet, in a day or two it would have been moldy and could have ruined not only my carpet, but could have ruined my entire home!
