Abstract: A double bucket cleaning system for use with microfiber mat mops. One bucket contains clean water; the second holds dirty water. The second bucket has a slide press for extracting dirty water from the mop. The system can use a connector to connect the two buckets together, or a single bucket with two compartments can be used. Both designs use a footpad upon which the user stands during the pressing operation. This ensures that the device remains in place during the sliding. Finally, once the dirty water has been extracted from the mop, the user can pick up clean water from the first bucket for the next portion of the floor to be cleaned. In this way, the user is able to quickly clean a large floor with clean water, instead of repeatedly dipping the mop back into dirty water.

Abstract: The present invention is a unique semi-automatic mop wringer. The mop wringer comprises a hollow housing vertically movably supported on a supporting structure by a suspension mechanism. The housing is engaged with the supporting structure through a rack-and-gear mechanism, so that a downward motion of the housing can be transmitted into the rotation of crank members which in turn drive a wringer roller to squeeze the mop against a wringer plate mounted inside the housing. A user can use the present invention mop wringer to wring a mop by placing the mop inside the housing, holding the mop holder and applying a downward force. The downward motion of the housing causes the wringer roller to move in a circular path to squeeze the mop against the wringer plate. When the user withdraws the downward force, the housing moves back upwardly to allow the user to repeat the process.
