The aim of the invention is to further develop a device of this kind so that stock liquor can be prepared from cleaning agent powder taken directly from its container without producing any dust, and the stock liquor thus prepared stored for feeding to industrial washing or cleaning machines. This is achieved by locating a secondary suction line end inside the stock liquor container at a point which is remote from the point of entry of a primary suction line into the bottom section. In addition, a fresh water line terminates in the container and has a water outlet aperture disposed so that the water is directed onto the stream of powder passing through the suction line.
