This dust extractor features the Milwaukee AUTOPULSE Filter Cleaning Mechanism that automatically cleans the filter after each use, ensuring more effective drilling for longer before needing to empty the dust box. The dust box comes equipped with a vacuum port that allows for suctioning out the dust with a large vacuum or dust extractor (such as the 8960-20) instead of dumping the dust out into a trash receptacle, ensuring minimal exposure.
