A method of manufacturing a mop wherein a cylindrical member is fixed in a groove of a sponge. The cylindrical member has a smaller length than the sponge and a flat surface located midway between a first end and second ends thereof. The flat surface is located in a same horizontal plane as first and seconds lands defined by the groove in the sponge. A single screw is turned into the cylindrical member at the center of the flat surface and a handle is turned onto the screw until an end of the handle engages the flat surface. A roller with a smaller diameter than the diameter of the cylindrical member has a first axial projection, which is located in a first opening in a strap, and a second axial projection which is in a second opening in the strap. The strap is flexed and the first and second axial projections on the cylindrical member are located in third and fourth openings in the strap such that the roller and cylindrical member are parallel to each other. The roller is retained in first and second rest positions by being positioned on one of the first and second lands of the sponge. The strap is adapted to rotate in an arc about the first and second projections on the cylindrical member from a first rest position to a second rest position. On rotation, the sponge is radially compressed between the roller and cylindrical member and axially compressed between the strap, roller and cylindrical member to remove liquid from the sponge. The diameter of the roller and a space relationship between the first and third and second and fourth openings in the strap assure that the roller is positioned on the first land in the first rest position and on the second land in the second rest position as the strap is rotated about the cylindrical member.
