I know nothing about shop environments but I do know about vacuums and the rumbas we use are fantastic. They can be programmed to go out at certain times each day. They return themselves to their chargers as well. The only human work is emptying the dust cartridge and replacing the filters when needed. I now work in a practically dust, lint, thread free environment thanks to "Hal," my favorite sewing tool. Some models are pricey but I recommend making the investment in the very best one they have. It's so worth it.
