A simplified and more convenient cleaning head for a wall washing machine includes a shell adapted for holding in the hand or mounting at one end of an elongated wand and also adapted to receive cleaning and rinse fluid lines contained in a vacuum hose attached to the shell. A fluid distribution manifold having a hinged connection in one end of the shell receives cleaning and rinsing fluids from a fluid switching valve in the shell and also serves to securely retain a replaceable sponge insert within the shell without the necessity of employing other fastening means for the sponge insert.
