I had bought this (under the model 1970R, but it looks to be the same model) because I found it refurbished for a can't lose price ($29.99 shipped, which is cheaper than smaller carpet cleaners that I've looked at), so I gave it a shot. I am very happy with the results of the machine's cleaning abilities. I am also very surprised at just how much dirt has been in my carpets. For what I paid, and the results, I give it 5 stars. However, I know that deal is far and gone, so I am giving it a more realistic 4 stars.The drawbacks are the width of the cleaning (quite narrow, leading to more paths, which is more time consuming) as well as a small container for your water/chemicals. The manual says to work in 3' x 4' areas, so you can imagine how long it takes to do a large room if you have to keep filling up. My other problem with it is the container that holds your dirty water is difficult to clean out the gunk and hair that collects in it.
