Comment: For our higher quality carpet in the master bedroom it took much longer than 4 hrs to dry. Our other, less expensive carpet dried much faster. The technicians did a great job cleaning our couch—looks and smells as good as new. My only suggestion would be that when they have to run their equipment upstairs, they put something down to cover the stairs. I was a little concerns there might be damage done to our recently refinished wood stair treads, but fortunately there were no problems. We had deordizer applied for a smelly accident on the couch and upstairs bedroom carpet.
