Abstract
A mop has an elongated mop head fabricated in sections, with each section being connected by a hinge to the adjoining sections on either side. The outermost sections can be rotated upward independently about their respective hinges so that they lie flat and inverted on the adjacent inner sections, forming a mop with a narrower mop head. The two outer sections thus folded on either side can again be rotated upward about the next hinge to lie flat and inverted on the adjoining inner section, with the outer section nested between the other sections in this folded position. By thus folding the various sections the mop head can be adjusted to a variety of lengths. A locking mechanism at each hinge causes each pair of sections to lock in either the extended or folded positions. The mop handle is attached to the center mop head section by means of a universal-type joint. A removable swab is further provided for the mop head.
