I have absolutely nothing but good things to say about Steam Sweepers LLC! They are fabulous! Their service people are nice and professional, but that is only the icing on the cake - and that is great icing! But what I really like is their method of cleaning. They use water, and they have a big, flat water bath they keep renewing. And this method cleans better than anything else that I have ever seen. Nothing cleans better than water, and there is no residue or chemical smell left behind! They are the best, and there is no one who does a better job!
