Abstract
A method of manufacturing a mop and in particular a mop head. The mop head is made from a rectangular piece of open cell sponge, a cylindrical core and a wringer assembly. A groove is cut along a longitudinal axis of the sponge while the external rectangular corners are also removed along the longitudinal axis to define a member with substantially five equal longitudinal surfaces. An adhesive is placed in the groove to join the cylindrical core with the open cell sponge. The wringer assembly has a strap which retains a roller which is attached to the cylindrical core to locate the roller at a fixed distance from the cylindrical core. A handle which is perpendicularly attached to the center of the cylindrical core has a tapered surface which provides a stop for the roller in the rest position.
