The Makita 18V X2 LXT Lithium‑Ion (36V) Brushless Cordless 1/2 Gallon HEPA Filter Backpack Dry Vacuum Kit (5.0Ah) (XCV09PT) is a powerful and portable clean-up solution that eliminates extension cords that trail corded backpack vacuums. It's also a powerful and portable dust extraction solution for contractors by bridging the gap between low-capacity on-board dust extraction systems and larger capacity but less portable wheeled canister job site vacuums. The Backpack Dry Vacuum Kit is ideal for cleaning crews, as well as for construction applications when used as part of a dust extraction system. The Backpack Dry Vacuum is powered by two 18-Volt Lithium-Ion batteries for 36-Volt power and performance but without leaving the 18-Volt LXT battery platform. The efficient BL Brushless Motor generates 70 CFM of suction and 44 of static water lift for fast clean-ups and improved dust extraction, with no cord to pull along or get in the way. The Backpack Dry Vacuum weighs only 9.9 lbs. (with empty dust bag and two 18-Volt 5.0Ah batteries) 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, and the 39 flexible hose has a telescoping extension wand with 20 - 34 of additional reach.
