Query: Wow!

This is a great carpet cleaner. I could not believe the color of the water the first time I used it!!! Carpet stayed wet for about 2-4 hours after cleaning. Product is somewhat difficult to set up initially, but once you get the hang of it it's not bad. Product is a little heavy to use, but works well. Also, it does leak if you forget to lock the handle in place AFTER EACH TIME YOU CHANGE THE WATER. You must remember to push the black button on the underside of the handle. All in all it's a good carpet cleaner and I would recommend it to others.
