Our carpet is 15 years old and had never been professionally cleaned. It is a light color and had become dingy in the traffic patterns plus had a stain from dog puke 3 weeks earlier. I chose Master's Touch because of the high ratings I read online. I was impressed that extra care was taken to not damage the corners of doorways by placing plastic protectors where the hoses would rub. But the most amazing thing is the carpet literally looked brand new when they left! Not only was it clean, the pile on the carpet was lifted and noticeably restored. The cost was reasonable as well. We'll use them again.
