I had a large area rug that had been given to me by a relative. It was old, and it had not been cleaned for quite some time. I wanted a carpet cleaning company that used the cold water immersion cleaning method, and I got on the internet to find one. The only company that used that method was Steam Sweepers LLC. I called them, and they picked the rug up. They brought it back when they finished, and they did a great job! It came out much better than I expected! They were very professional and efficient people!
