I have a 20” whisper wash eagle wash pro with an 8gpm machine. If you have not made the switch get, you won’t regret it. I’ve doubled my speed and completely eliminated any striping. I really don’t even feel the need to post treat anymore but I’m still not sure about that.
They only disadvantage that I have noticed is the 4 nozzle bar is noticeablely lower to the surface as in if I turn the sc on its side, the edge of the bar will hit the ground. I’m getting adjusted to the height, knowing what to hover over and what I can clear. I do some older home in the city, everything was built on swamp around here so a lot of uneven concrete to wash.
Is it normal for the bar to be this much lower from 4 to 2? Do I still need to post treat if my coverage is perfectly even?
