With regard to surface cleaners, I’ve seen discussion about what degree tips to use, and whether or not you should use 1 or 2 tips per arm (on a 2 arm unit). What I haven’t seen discussed is 4 arm surface cleaners. Why is that? I’m guessing they’re designed for higher flow machines, maybe 8 GPM and higher?
Let’s say you have a 8 GPM PW. All else being equal, would there be a difference between using a 2 arm surface cleaner with 2 tips per arm and a 4 arm surface cleaner with 1 tip per arm?
