Bests & Worsts Reviews from Amazon

This product worked great the first time I used it to wash some lawn chairs. Two weeks later, I used it to wash my patio. After about 20 minutes I noticed a drop in pressure and turned the unit off immediately. Then I noticed that the unit was leaking what appeared to be oil that is homogenized with water. I confirmed this when I saw the same type of oil/water mixture in the oil chamber. My guess is that a gasket has failed or something worse has happened. I should have trusted the other reviews and stayed clear of this product. Amazon to their credit gave me a full refund without any hassles--I was very impressed with Amazon's customer service. I will continue to shop with Amazon with confidence.
