ABSTRACT:
An extendable pole for window washing includes a plurality of substantially hollow elongated rigid tubular sections, each of which has a lower end and an upper end and a substantially cylindrical outer side wall. The upper end of one section is mechanically connected to the lower end of a section there above to form a substantially continuous pole. Apertures are formed in the side wall of each of the tubular sections adjacent the lower ends and adjacent the upper ends. An elongated flexible tube which is slightly longer than its associated tubular section extends through the interior of the tubular section with its ends passing through the lower and upper apertures to the exterior thereof. Fluid connectors at the ends of each of the tubes connect them together so that the tubes are in fluid communications with each other.
