ABSTRACT:
An improved deck mop to retain yarn comprising an elongated rod having an upper section and a lower section. An exterior rotatable sleeve threadedly surrounds the lower section which includes an interior movable piston which is further connected to a stationary spring. The lower section at its bottom end is connected to a first and second rotatable and removable clamp member comprising a respective bottom brush and bottom scrubber for cleaning. The mop through a respective clockwise and counter-clockwise rotation of the sleeve controls a respective closing and opening movement of two clamp members to thereby respectively hold or release a mop yarn, wherein the closing movement further results in contracting the spring so that the reduced spring stores a compression force having sufficient power to enable it to push the clamp members rotatably apart when the sleeve is rotated in the counter-clockwise direction.
