Abstract: A mop wherein the mop head has two mirror symmetrical plate-like sections which are attached with play to a support at one end of a mop handle by hinges each of which enables the respective section to move toward or away from the other section while the sections confront each other in collapsed position of the mop head. This renders it possible to expel moisture from cushions at the undersides of the sections. The sections are pivotable to and can be releasably held and propped in extended positions in which they are substantially or exactly coplanar and the cushions at their undersides are ready to sweep the floor.
