ABSTRACT:
The suction capabilities of a original-equipment (O.E.) extractor providing inadequate suction are enhanced, thereby avoiding the need to purchase another and more expensive extractor, by the addition to it of a vacuum booster. The booster contains its own blower and an electric motor for driving the blower, and the inlet of the blower is connected to the outlet of the O.E. extractor. The booster is conveniently mounted to the O.E. extractor by means of suction cups. A doubling of the suction level can be achieved in this manner.
