DESC: A powerful mess needs a powerful vacuum cleaner. The Milwaukee line of wet/dry vacuum cleaners offer power to spare. All wet/dry vacs have a positive water shut-off to protect the motor during wet pick-up situations. Heavy duty filters can handle large pieces of material as well as dust. Model 8936-20 offers a poly tank and heavy duty casters. It also offers a 3 position switch, on/off/on demand.
