I just bought my Carpet Washer and haven't used it yet, but I owned a Hoover Carpet Washer previously and was pleased with its' performance. The packaging was great and the instructions are straight forward. One negative. Not until you buy the product and READ the instructions that there is a warning about Berber carpets. My past experience was that the Washer works on Berber, but now I'm going to have to test a closet area to ensure no carpet damage. Thus the four star rating v. five.
