A washing machine having an impulse pulsator is disclosed. The washing machine has a pulsator assembly having a first pulsator rotating in the washing tub and the impulse pulsator assembled with the first pulsator. The first pulsator has a supporting bar being extended to the axis direction thereof, and the impulse pulsator has a cylinder part assembled with the supporting bar by insertion. On an outer surface of the cylinder part, many wings are disposed symmetrically to be centered with the axis. The first pulsator and the impulse pulsator are fixed with each other to be capable of relative rotation within a predetermined angular distance. When the motor begins to drive the pulsator assembly, the first pulsator begins to be rotated first, and after the rotation of the first pulsator at the predetermined angular distance, the impulse pulsator begins to be rotated by the first pulsator. Due to the wings of the impulse pulsator, a strong water current is generated in the upper part of the washing tub, so that the washing efficiency is improved. In that situation, the water current in the lower part in the washing tub by the first pulsator and the water current in the upper part in the washing tub by the impulse pulsator are generated at different times from each other. Accordingly, the turbulent force between the water and the laundry is greater, and the washing efficiency is much improved.
