I purchased your carpet cleaner and the carpet prespotter and a used couch for our community theater. I was amazed how well the carpet cleaner and prespotter were able to clean the couch. (It was really dirty. When I saw it on stage I thought we wouldn''t be able to use it because it looked so bad under the lights.) After cleaning it it looked as clean as new. I couldn''t even see a difference when I lifted back the folds of the fabric.
