1. A mop, comprising: a mop head comprising a cleaning face including a first end portion and a second end portion, the first end portion interconnected to the second end portion by a hinge device so that the first end portion can be pivoted about the hinge device relative to the second end portion for forming a coplanar state or a non-coplanar state with the second end portion; a mop shank; a joint connecting the mop head and the mop shank; a position-limit mechanism interfacing with the joint to limit movement of the joint relative to the mop head, wherein the position-limit mechanism includes a slotted opening, and further wherein the joint is moveable within the slotted opening; and a drive device positioned between the hinge device and the joint to bias the mop head to the coplanar state; wherein the mop is configured such that the non-coplanar state between the first and second end portions is realized when a downward force is exerted on the mop shank in a direction of the mop head; and further wherein the non-coplanar state includes a forward edge of the first end portion, opposite the second end portion, extending upward in a direction of the mop shank.
