This is the new 12" Whirl-A-Way from BE Pressure. This Whirl-A-Way is great for cleaning driveways, sidewalks, decks, roof tops, sides of houses or any flat surface. This Whirl-A-Way consists of a heavy duty polypropylene cover and a welded steel rotary arm. What is so neat about this Whirl-A-Way is you can use your existing gun and wand. A very fast and easy hook up.
