Working on all Milwaukee® 18 V slide-on batteries, RED LITHIUM™ or Ni-Cd, the 0880-20 wet/dry vacuum offers long continuous run time and high air power and suction to provide quick and easy removal of dust, debris and water. A washable, reusable wet/dry HEPA filter delivers excellent fine dust collection and does not need to be changed between wet and dry applications. The stackable toolbox design, on-board hose and accessory storage offer excellent portability and convenience, a built-in blower port allows the vacuum to double as a blower and the 1-1/4 in hose allows standard vacuum attachments to be fastened.
