Abstract
A mop having a cylindrical core fixed to a handle by a fastener member. An absorbent material is attached to the cylindrical core. A U-shaped bracket has first and second legs attached to the cylindrical core by first and second pins. A roller is positioned a predetermined distance from the cylindrical core by third and fourth pins extending through the first and second legs. A resilient edge on the absorbent material holds the roller adjacent the handle. An input force applied to the U-shaped bracket moves the roller in an arc about the first and second pins to allow the roller to engage and compress the absorbent material and thereby remove material absorbed therein.
