Not quite a power washer, but almost! I clean old driftwood and anything in my garden, auto, rocks and whatever. It has two ends so you can fan out or pin point. Works excellent!The only caution I have is the nibs can easily fall in the tall grass to never be seen again. When you change nibs, be sure to do it over a surface that you can easily see brass on. I had this nozzle in the past and lost both nibs in no time=no pressure. Now I'm more careful and it's fine.
