Abstract
A sponge mop retainer is attached to the end of a handle with a sponge member removably secured within the retainer. The retainer keeps the sponge member from rolling out when the mop is in use by tending to adhere to a surface while it allows the sponge member to be removed when the sponge member is worn out or dirty. The sponge member has four opposed longitudinal slits, one on each of four opposed surfaces. The retainer has a top wall and two side walls with the bottom edges of the two side walls having flanges which project inwardly, substantially toward one another. The free edges of each of the flanges have enlargements, substantially along their length, of a greater thickness than the thickness of the flanges which are engaged in two of the opposed slits to oppose movement of the sponge member away from the retainer. The enlargements, which may be in the form of barbs, enable the sponge member to withstand the friction forces involving in cleaning a surface without becoming disengaged from the retainer.
