Abstract: An adjustable curvature cleaning structure adapted to clean both flat and curved surfaces. The cleaning structure includes a frame having a base operatively engaging an elongated handle structure and at least one arm projecting away from the base. The arm includes multiple link elements with hinges disposed between the link elements such that the arms are bendable in curved relation to adjust elevation relative to the base. At least one adjustable length cable extends along the arm and is operatively connected to a length adjustment mechanism.

Abstract: A mop head with a structural base and a resilient, compressible cover defining an internal void volume forming a reservoir that can be at least partially filled with a cleaning liquid through a surface opening in the cover. The structural base includes one or more liquid discharge channels which are normally closed off by spring-biased stopper members to prevent discharge of the cleaning liquid. The cleaning liquid may be selectively discharged by application of compressing force against the cover during use. The application of such compressing force displaces the stopper members thereby opening the liquid discharge channels and permitting the cleaning liquid to flow outwardly through the discharge channels and away from the mop head.
