I have carpet in my loading room. I constructed a shelf system from 2X12 from floor to ceiling, and 12' wide. I "decked" half the room with the same 2X12 under the loading bench and across the room far enough to roll my chair and comfortably work at the bench. Pressed tightly together and held in place by screwed end strips. I have used a small shop vac (2 gallon) for many years in my loading room. Powder, primers, etc...... No issues. Use a vacuum that has the fan and motor on the BACKSIDE STREAM of the receiver tank. NEVER use a vacuum that passes all the junk past a fan, they will explode if you happen to suck up a live one. The filter canister will prevent powder or primers or anything else from reaching the fan blades. If you do have carpet, Home Depot and Lowes both have carpet adapters that will fit shop vac hoses.
