They had to use a gas pressure washer with the wand, it is a joke. Don't get it, It is a waste of your money. Buy a good gas pressure washer. I have great water pressure on one side of my house and it still didn't work like they said.
Junk, Junk, I can pee harded than this wand. I tryed this on my Mold on the side of the house, I even used a cleaner for vinly sideing and it didn't clean it off.
