摘要： A dust extraction device for a hand-held power tool includes a housing, a mechanical interface for releasably connecting the dust extraction device to the hand-held power tool, a dust-collecting chamber which is connected to a filter unit, and a filter-cleaning unit. The filter-cleaning unit has an impact element which is mounted moveably in and/or on the housing of the dust extraction device. The impact element is designed to act upon the filter unit directly with an impact-like force.
