  • Patent number: 5263223
    Abstract: The invention is an improvement in floor-standing machines for cleaning inside surfaces of buildings such as walls and ceilings. The improved machine includes a first support for supporting the apparatus in an upright orientation and a second support for supporting the apparatus in a horizontal orientation. The machine may readily be moved on the floor in the upright orientation and in dolly-like fashion and supported on the floor for use in a "face up" horizontal orientation. The machine has modular dirt-collection, cleaning solution and rinse water tanks, each of which is slidably attached to a mounting member. The tanks are readily removable for filling and/or emptying as needed. Implements such as cleaning wands and the like are conveniently stored at the side of the machine.

  • Patent number: 5186392
    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.
