Makita XCV09PT .5 gal LXT Brushless HEPA Filter Backpack Dry Vacuum Kit (5.0Ah) 36V 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.
