Have a buddy that has a PW business and he got me into it. I just diy my own stuff. It’s therapeutic. I have a little Sampson 4 gpm 4200 psi machine, dewalt turbo nozzle, 18" surface cleaner, normal tips that came with the machine and 2 story tips (pink and baby blue) spray and soap. Its just a basic do yourselfer setup. I’m just a guy who has a machine and cleans his own stuff. Nothing special here!
