Needed to clean my composite deck so a few days ago bought the xPX3050, PWSC 15" Rotating surface cleaner and an extender wand to use with the surface cleaner. Assembling was very easy but you will need to unwind the hose before using. I inserted the 25 spray nozzle and rinsed the dirt off, thought the power was great. I connected the surface cleaner and started cleaning, it was so easy, just like a vacuuming a rug. The water comes out around the bottom of the surface cleaner keeping me bone dry. NO MORE SCRUBBING!
