Abstract
This disclosure relates to a sponge mop refill assembly designed for use with different mop head designs. The assembly includes a sponge, a pair of backing plates secured to one side of the sponge, and an adapter for each backing plate. Sponge mop heads include a squeeze plate that extends across the upper side of the sponge and is removably attached to the two backing plates on the sponge. In one mop head design, the squeeze plate and the backing plates include mating slot and flange parts for connecting the backing plates directly to the squeeze plate. In another mop head design, the connecting part on the squeeze plate is recessed and therefore not directly accessible to the mating part on the backing plate, and in this instance the adapters are positioned between and interconnect the squeeze plate with the backing plates. In still another mop head design, screw holes are formed through the squeeze plate, and the assembly may further include screws and nuts for connecting the backing plates to the squeeze plate.
