A cleaning device has a support body with two foldable frame elements and a cloth which has two pockets for receiving the frame elements. The two frame elements can be detachably arranged in the pockets. A holder may be arranged inside each packet, the holders and the corresponding frame elements may be interconnected in a nondestructive manner.

A mop frame with a base, a first extension that is slidably coupled to the base, a second extension that is slidably coupled to the base, a first lock that is mounted to the base, and a second lock that is mounted to the base. The first extension and second extension are each operable to slide with respect to the base between a retracted position and an extended position. The first lock and second lock are operable to releasably lock the first extension and second extension, respectively, to the base in any position between the retracted position and the extended position.

The device includes a substantially cylindrical oblong rigid extension member having a distal end upon which is formed an articulatable jaw structure, and an opposite proximal end including a hand-operable trigger for actuating the jaw structure between open and closed positions. A collector sock made from a pliable sheet material can be mounted upon the jaw structure. The sock has an open end and an opposite closed end. The inner surface of the sock surrounding its open end includes a plush surface which can conform to uneven or embossed surfaces on the fan blades. The sock can be mounted to the paddles of the jaw by folding the opening backward over the paddles to engage fasteners. When the jaw structure is in the open position, the open end of the mounted sock forms a maw for accepting the end of the fan blade therethrough. The maw can be translated over the fan blade until the sock enwraps essentially the entire fan blade. By allowing the jaw structure to return to the closed position, the maw collapses and the closely contacts the top, bottom and edge surfaces of the fan blade. As the closed jaw structure can be withdrawn from the fan blade so that the sock scrapes off and captures dust and other debris from the fan blade.
