This is a wand mounter water broom for washing car undersides. I was unable to find a water broom that worked without a pressure washer. I often drive on the beach and want to wash off the salt from under the car after a day of fishing. This tool solves that problem. The one end threads onto a hose and the other fits standard threads for a paint pole. Any pain pole should work. After many tries I was able to get the nozzle shape to spray in a nice 45 degree fan pattern.
