Abstract

A method for economizing detergent for an automatic-cycle washing machine (60) comprising a tub (61) housing a rotary drum (62), a discharge pipe (3) connecting said tub to a pump (2) and into which a filter (65) is connected, and a delivery pipe (4) from said pump (2), characterised in that the wash water fed into the machine undergoes a pulsating movement by way of the pump, so that said pump (2) and the relative pipes (3, 4) are washed and the detergent present in the water is dissolved.
This method is implemented by a device characterised by comprising means for effecting the pulse-operation of the pump.
