Abstract
A manual clothes-washing device made up of a handle, which is fastened to a washing body, a sheath and a splash cone. The washing body is a generally concave disc with a plurality of apertures connected to a generally cylindrical tube that extends from a central portion of the disc to a tube end threaded for connection with the handle. The sheath is placed over the washing body and connected to the handle. A splash cone attachment fits over the second end of the sheath. Clothes are washed by alternatively plunging and lifting a portion of the device in a mixture of clothes and liquid to suspend the soil from the clothes within the liquid.
