Abstract: A window washing pole system incorporates a linear actuator that causes the washing head to move in a reciprocating manner to provide a scrubbing action for the washing of windows at a height above the operator's head. A standard extendable window washing pole system in which extensions can be added to vary the length of the apparatus, and thus the height the apparatus will reach, is adapted to be connected to the distal end of a linear actuator, or the actuator is incorporated into the proximal end of the pole system, and operable on compressed air to provide the reciprocating action for the washing head. Supply lines for delivering washing solution to the washing head can still be utilized. Controls for operating the linear actuator can be provided to enable the washing head to be operating in a scrubbing mode or in other modes, such as a squeegee operating mode.
