ABSTRACT:
Apparatus for drawing liquid by suction from a surface and into a reservoir including intake and exhaust conduits communicating with the reservoir. The intake conduit has an inner end which is shaped to provide a continuous change in the path of flow of the liquid flowing therethrough to thereby avoid impact of the liquid with adjacent structure and thereby minimize aeration of the liquid. The apparatus can be in the form of an attachment for a conventional vacuum cleaner or can be self-contained. It is constructed to provide assurance that the suction force produced is such as to prevent liquid from passing out of the reservoir through the exhaust conduit.
