I want to be the very best I can at my service I offer, I would never wash a home with a 12 volt, maybe a stucco home to apply chemical but rinse with a 10 gpm for sure
Hey Dave a matter of fact you can clean both with 12v but run one tank for your roof mix an a seperate tank house wash doing only residential ! Just doing roofs your leaving a lot of cash on the table! It's a pain in the but using 2 tanks but depends on your cash! A small investment in a pressure washer an DS is the way to go .But for roof cleaning you would still need a tank an designated pump.Not to knock Xjeting. Do a little research on this forum an you decide whats best for you.
