Curved mop and related method

A mop tool comprising:

• a one-piece, molded polymer mop head of substantially rectangular profile having a length dimension and a width dimension, wherein the length dimension is at least two times greater than the width dimension, the mop head including a substantially centrally located stirrup structure defining an attachment element adapted to operatively connect to an elongated handle structure, wherein the stirrup structure comprises a pair of spaced-apart posts projecting away from an upper surface of the mop head and a pair of opposing projections extending inboard from the posts, the mop further including a lower face having a concave arched profile such that the lower surface defines an arch having an apex disposed at a position in underlying opposing relation the attachment element, a plurality of hooking elements projecting away from the lower face, the hooking elements being disposed in attachment zones adapted to engage a surface of a disposable cleaning element in hook and loop connection, the lower face further including interstitial zones free from hooking elements and hook-free end zones defining substantially smooth surfaces, the hooking elements being adapted to engage a surface of a disposable cleaning element in hook and loop connection, the hooking elements having a length not greater than 5% of the height of the arch at the apex, wherein the mop head is flexibly resilient such that the arch will deflect to a flat condition upon application of a downward vertical force of 1 pound force or greater through the handle structure in a line perpendicular to the center of the mop frame during mopping use and the arch will thereafter recover upon removal the force through the handle structure.
