I had them come out and clean my couch. It was a couch bought from a friend that had a lot of dog hair and old dog smell in it. They did a great job explaining what they were doing as they went along. Very fastidious work and they try very hard to make sure it is as clean as possible. They were honest with me saying the deodorizer is good, but the amount of smell in my couch might take a few more rounds to get out. Regardless, the couch is wonderfully clean and the smell is so faint, I can live with it until the next routine cleaning in 2 years. I highly recommend them.
