ABSTRACT:
A floor mop has a stick 10, a mop head 11 including a mop fabric 12 and an lower handle 14 and an upper handle 19. The lower handle is axially and rotatably movable relative to the stick 10 and is attached to one end of the mop fabric 12 of the mop head. The other end of the mop fabric is non-rotatably attached to a lower end of the stick 10. The upper handle 19 is attached to a sleeve 16 that is mounted on the stick 10 to enable the rotation of the stick relative to the lower handle 14 to wring the mop fabric 12 of the mop head. According to the present invention, the upper handle movably engages the sleeve 16 via a protrusion that extends into a helical groove 17 defined in the sleeve 16. The helical groove may have a slope that is gradually reduced as the helical groove extends from an upper portion of the sleeve to a lower portion of the sleeve.
