I don’t necessarily use it for soaping, though sometimes. It’s just a good utility wand to have. Say for cutting in on concrete, steps, etc where you don’t really need 3000psi maybe. Small fences or decks, rinsing, etc. Basically a more directed and less messy ball valve. I have a soap tip on one side and a 40 deg on the other. Both probably only shoot 5-10 feet. I wouldn’t use it for soaping a house.
But say on a drive or a commercial job, can lay down coat of soap and while it’s dwelling can do your cut ins where surface cleaner can’t get get. Or maybe you got a fairly high brick wall or foundation and need more pressure than you can get with your DS nozzle can use just however much pressure you need.
Kind of like using a short range m5ds nozzle on a wand Except you have high pressure capability also. It’s just infinitely adjustable from 50psi to 3500 psi.
I’ve had several, including some high dollar Sutners but the one I got from NT have had over a year and works great. In fact, after I got it, worked so much better than the Sutner I had I bent the sutner one in half and threw it in the trash can.
