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.

Une perche télescopique pour lavage de fenêtre comprend une pluralité de sections tubulaires rigides allongées et sensiblement creuses, dont chacune comporte une extrémité inférieure et une extrémité supérieure et une paroi latérale extérieure sensiblement cylindrique. L'extrémité supérieure d'une section est reliée mécaniquement à l'extrémité inférieure d'une section de dessus pour former une perche sensiblement continue. Des ouvertures sont formées dans la paroi latérale de chacune des sections tubulaires adjacentes aux extrémités inférieures et aux extrémités supérieures. Un tube souple allongé qui est légèrement plus long que la section tubulaire connexe s'étend à travers l'intérieur de la section tubulaire, ses extrémités passant à travers les ouvertures inférieure et supérieure à l'extérieur de celui-ci. Des connecteurs de fluide aux extrémités de chacun des tubes les relie ensemble de sorte que les tubes soient en communication fluidique l'un avec l'autre.
