strange idea. Why use many shop vacs if you get a dust collection system with an induction motor at [Harbour Freight for $299](https://www.harborfreight.com/35-gallon-2-hp-high-flow-high-capacity-dust-collector-59726.html). Okay you’ll have to add the cartridge filter to get an acceptable wood dust filtering.

Shop vacs that run permanently like when used in a CNC will make replacing carbon brushes within less than a year.
