I have a 4000psi 4gpm cold water machine, 30gal tank as a buffer tank when needed, 100ft hose, 2 ladders, pump sprayer for applying chems to concrete and decks, of course chemicals, and I'll be getting x-jet next week. I dont have a surface cleaner yet which I should have by the time im up there, and hopefully a burner. nothing fancy but I have to start somewhere....
