We live in an RV and experience a high level of road dirt plus our animals don't help clean much. Several times a year we use professional carpet and upholstery cleaners in many place in the U.S.A. Without exception they were popular nationwide businesses, they were often late or lost, and all used water as a base cleaner. This time we decided to try local there were two outfits available one with the standard water base and HealthTech an advertised green and dry cleaners. We chose Health Tech and have never been more pleased. They were right on time when and where they said they would be. The agent was not only knowledgeable but a pleasant, professional. He went right to work and cleaned in a timely fashion with the best results ever.. Our usual experience is locked out of the house for about a half a day and the spots slowly return within a day or two.This time we moved right back in, the carpets never smelled better, and the spots have not returned as of this writing two weeks later. We will recommend all our friends and family to use these wonderful folks. read more
