Ok next project after surface cleaner.. Build a better pitch witch... ( Note to Self ) LOL
This thing looks pretty easy t0 build . We cleaned my wifes uncle's roof. and used one of the water brooms from home depot and an extension wand.. We modified the water broom by putting tires from my old roll around pressure washer on it. they were aired up knobby tires .. gave us a 3 inches off the roof spray ..with the big machine and hot water we used no chemical... I will get some pics as soon as I get to the shop this week.
