Abstract: A mop head assembly includes a backer plate and one or more rods provided on the backer plate. The rods are provided to maintain the shape of the plate, with a planar cleaning surface geometry, and to further resist warping of the plate.

Abstract: A resilient device for joining a handle to a pivot bar of a wire support frame of a dust mop or other work member which allows for hands free operation to attach and remove the mop head or other work member. The holder includes a resilient member having first and second jaws extending generally parallel from one end of a base. Each of the jaws has an inner wall and an outer wall and which define at least an outer engagement slot and an inner engagement slot between their respective inner walls. The jaws also define an open end distal to the base and a closed end proximal or at the base. The outer engagement slot being arranged transversely to an axial direction of the first and second jaws proximal to an open end portion of the jaws opposite to the base. The inner slot is proximal to a closed end portion of the jaws proximal to the base. Typically, the entire apparatus can include a single or unitary piece of plastic or a single substance.
