We've been using Monster Clean for several years now. We happened upon them by chance. We had used several different carpet cleaners in the past and were not happy with any of them. But with Monster Clean, it was a different experience. They are always professional and their fees are reasonable. They even talked us out of certain things because they didn't think it would be a benefit to us. They offered us a less expensive alternative. For examply, they cleaned the top part of the upholstery that shows and not the bottom part and charged us less for that. They are always on time and are competent and knowledgeable people.
