The 20V MAX* 1/2 Gallon Wet/Dry Portable Vacuum Kit comes with a 4 Ah battery and runs off all 20V MAX* battery packs for long runtime. The HEPA wet/dry filter traps 99.97% of dust at 0.3 microns. Dual clean-up modes allow for debris removal with either the front utility nozzle or extendable rubber hose. The portable vacuum is easy to use with a heavy duty tank latch for emptying and cleaning, a large on/off switch for one-hand access, and a heavy-duty rubber hose that provides durability and flexibility.
