The Makita 18V X2 LXT Lithium-Ion (36V) Brushless Cordless 1.6 Gallon HEPA Filter Backpack Dry Vacuum (XCV17Z)is a powerful and portable clean-up solution that eliminates extension cords that trail corded backpack vacuums. The XCV17Z is ideal for cleaning crews, as well as for construction applications when used as part of a dust extraction system. The XCV17Z is powered by two 18V Lithium-Ion batteries (sold separately) for 36V power and performance but without leaving the 18V LXT battery platform. The efficient BL Brushless Motor generates 78 CFM of suction and 44 In. of static water lift for fast clean-ups and improved dust extraction, with no cord to pull along or get in the way. The XCV17Z weighs 15 lbs. (with empty dust bag and two 18V 5.0Ah batteries, batteries sold separately) and has padded shoulder straps and waist belt with multiple adjustments for a comfortable fit. Cordless and compact, the push button power selection controller attaches to the waist belt of the harness for convenient operation. The efficient HEPA filter combined with the filter bag captures large, small and micro dust particulates and the half-gallon dust collection container is easily removed for dust disposal. When using two 18V 5.0Ah batteries, users will get up to 140 minutes of continuous operation on low setting and 40 minutes on the high setting.
