ABSTRACT:
A water-conducting cleaning machine, in particular a household dishwasher or a household washing machine, has a processing vessel. A device for repeated, automatic metering of doses of a powdered detergent includes a detergent holder having an interior and an outlet opening. A metering and dispensing device is associated with a duct, is disposed below the outlet opening and has at least one indentation with an interior for receiving individual doses of a powdered detergent from the outlet opening and for feeding the individual doses to the processing vessel in a dispensing position. A compressed air generator generates a flow of compressed air continuously acting upon the interior of the detergent holder and upon the duct, and acting upon the interior of the indentation in the dispensing position.
