My shop vac is on casters.I avoid oily metal shavings because of the chance of combustion.Fire in a vacuum cleaner will get exciting real fast.I use a magnet in a plastic bag to collect steel shavings.Aluminum and iron dust can burn as in thermit welding.A boy used his dads belt grinder on some aluminum parts.Dad was grinding away on an iron part when the dust lite off.Dads beard was burned a little.
