Upon receipt of this inexpensive surface cleaner, I was pleasantly surprised with the quality of the materials. The metal components were high grade stainless steel and bronze. The plastic shroud was heavy duty and the wiper brush was very well made and attached. The quick-connect male plug provided on the cleaner fit my pressure washer disconnect perfectly with no leaks. It's maiden voyage was to clean a 1,800sf painted wood deck. The results were equal to if not better than if I had used my pressure washer with a rotating nozzle, in half the time. Next was the stamped concrete pool deck. it was a little harder to push around on the concrete than the painted deck, but it still gave me excellent results. I have already told my brother that he needed to buy one. I am very pleased!
