A self-contained portable device for collecting dust and other particulate matter or the like. There is a housing with partially open sides sufficiently large to allow the entrance of an operator\s hands. A sensor is activated when the operator\s hands are placed within the device. The sensor activates the vacuum motor and light source so that the work area is illuminated and particulate matter and dust can be drawn away from the work area. A removable and disposable filter bag collects the dust particles and can be disposed of when full. The operator does not come in contact with any contaminated dust or particulate matter in disposing of the filter bag.
