I thought they were very good and I like the results of the carpet cleaning. I have a short shag and first hired Silver Olas Carpet Tile Flood Cleaning for the bedroom. Then I had them come back and do the living room. They did a very good job both times and I was very happy with them. They went over the carpet twice after first spraying it all. I would definitely call them again and recommend Silver Olas Carpet Tile Flood Cleaning
