  • Publication number: 20080083080
    Abstract: A plurality of ridges is woven into the water-absorbing material on a floor mop's attachment, eliminating the undesired “flip-over” caused by the wet stickiness of the fabric surface when users are mopping the floor. The parallel ridges provide the “push-away” force to resist the stickiness, and also increase the scrubbing power of floor mop due to the hardness of the ridge material.
