Bought it became my dog was sick on the silk rug we brought home from China. I knew I couldn't use detergents and wasn't calling a service cleaner. With a few passes, using just water, my rug is like new! I could not be happier. I also used it with cleaning solution on a couple of spots on a bedroom rug. Those spots are gone! For less than the cost of a rug cleaning service, I took care of everything.
