Abstract
The invention is an improvement in an extendable elongate liquid-applying device of the type used for cleaning interior walls and ceilings. The improvement includes first and second tubular members telescoped together and slideable relative to one another to extend and retract the device. One of the members has a proximal end; the other has a distal end and an attached angularly-oriented nozzle. A continuous length of coiled flexible hose extends within the members and connects to the nozzle member. That is, the hose extends unbroken along the lengths of the members, from the proximal end to the distal end, to provide discharge from the nozzle member regardless of the relative positions of the members. A separate base member plugs into the proximal end and has a valve for controlling liquid flow. With a nozzle attached thereto, the base member can be used alone for 'close in' cleaning.
