great features. Love the long hose it comes with
just tried the washer; it is almost too powerful, works great! my time is cut in half or more with this washer. Cleans concrete and the home better than all the old one I bought in the past. Look forward to trying it on the farm equipment.

First Amazing Pressure Washing
I bought this last week. Setup was fairly quick and I was so shocked by the power that I almost got knocked off of my feet. It leaves the small section I did clean and I didn't even have to use chemicals.
