After a wonderful cleaning of most of my home last winter when a several year old Coke stain was removed and a several year old bright red lipstick stain was removed as well as lots of dirt and miscillaneous stains were vanished, I was expecting similiar results with this cleaning. The carpets were not that dirty; however, there were several spots including one large area where our new dog urinated. There was also a tea stain. I did agree to the amount of the special cleaner that would correct the stain cosmetically but not the underflooring. The stains did fade but still are present. I understand that certain stains are difficult or impossible to remove; however, I was expecting better results for the amount of money paid.
