The technicians who helped me from Mass Carpet Care were very professional when they cleaned five or six rooms of carpeting. The reason why they didn't get a five is because when they left, I asked if they had an air freshener--just something that makes the carpet smell clean; but, when they left, it smelled like wet carpet. I wanted it to be clean and fresh smelling, and it didn't. And I don't think they prespotted at all because there were a couple spots that didn't come all the way out.
