Do you REALLY need that many motors? I used to work part time maintaining equipment for a family had several laundries here locally, and a couple of car washes. Those car wash vacuum motors are nothing short of scary. I used two of them to repair a central vac in one of the laundries. Ended up unhooking one and it STILL generated so much static electricity in the hose that it was painful!!
Anyhow this is marvelous. I've dreamed of such, but don't know much head theory LOL
