Abstract
A wringer mop has a conventional handle with mop fibers extending from a lower point on the handle to a collar that can be lifted to a raised axial position and twisted to wring the mop. The mop also has a pawl on a ring fixed to the handle. When the mop is wrung, the pawl automatically engages a set of raised internal ribs inside the collar to prevent the mop from unwinding. The mop can be returned to normal use by simply pushing the collar down, without the need to fuss with button or levers to disengage the pawl from the ribs.
