16GPM Softwash?

I just came across a new 16GPM Softwash pump from Southeast Softwash that has me intrigued. They are taking pre-orders now. It’s $1500 (plus a separate controller-no price yet) which is pretty pricy but I imagine it will pay for itself quickly. I’m trying to imagine how fast I could rinse a house with this monster. I was able to try a buddy’s 11GPM P20 a while back and loved the volume of water it puts out. I don’t love the negative reviews on that system nor the AR’s. With no history of reliability, this is a bit risky. Is this the future of softwashing?

what size hose they recommending?

3/4 inch
