ABSTRACT:
An extension pole including an outer tube connected to a water source and an inner tube positioned in a telescoping relationship to the outer tube. The inner tube includes a series of spaced apart openings that are engaged by a biased locking member positioned on the end of the outer tube. The locking member may be manually released by activation of a release button connected to locking member, thereby allowing inner and outer tubes to be moved with respect to each other. The extension pole also includes a locking nut assembly positioned on the free end of the inner tube for attaching the tube to cleaning tool and preventing rotation of the cleaning tool during use.
