This company is very profesional. They do a complete cleaning for one price. I was sceptical at first, but my friend told me they were on angie's list and had been in business over 20 years.So I gave it a shot and the carpet was clean! Did'nt take days to dry, and did'nt stink! I would refer them to my friends with no regrets. The big truckmounted units are the way to go.
