An apparatus and a method for repeated, automatic metering of precisely metered quantities of a powdered detergent into water-carrying cleaning machines, in particular household dishwashers and household washing machines, include a detergent holder and a metering and dispensing device having a movable metering device with at least one metering receptacle. The interior of the detergent holder and a guide of the metering and dispensing device are acted upon continuously by a stream of compressed air. Therefore, clumping of the highly hygroscopic powdered detergent and an expensive, complex apparatus, which requires a high drive torque and a high air pressure, are avoided. The metering device has only one metering receptacle. The metering and dispensing device has two chambers communicating with one another. The detergent fed into the first chamber is fed gradually, during the motion of the metering device, into the second chamber, which has an opening toward the treatment vessel. The treatment vessel-side opening of the second chamber is closed by a lid connected to the metering device. The lid, in the dispensing position of the metering and dispensing device, uncovers a discharge opening, from which the metered detergent is fed gradually to the treatment vessel. Sealing elements which surround the treatment vessel-side opening of the second chamber are provided, which cooperate with the lid.
