The GAS 18V-12 MC cordless vacuum cleaner ensures M-class dust protection. It removes most types of dust found on construction sites - concrete, brick, filler, tile adhesive, and more. The innovative ESD solution automatically dissipates electrical charges, and its auto-start feature operates the vacuum for you, allowing you to focus entirely on your work. Simply attach the auto-start module to your tool and pair it with the GAS 18V-12 MC. Once paired, the auto-start detects vibrations from the running tool and automatically turns the vacuum on and off for you. The powerful BITURBO brushless motor and the larger filter provide excellent suction power for all demanding tasks - all with just one 18V battery.
