Dust laden carpet is 11% more absorbent than clean carpet is.
Just flood the carpet each time you fuel up, then use your on board vacuum cleaner to extract fuel, and empty into the tank and needed

Very few commercial vacs remove all dust.
I agree on the Milwaukee vac especially if you already have Milwaukee cordless gear.
I've messed around with cyclonic dust separators for a shop vac a couple of times.
They are about 95% effective of you get the design right...
