Abstract

A method of mopping a floor is disclosed.

1 . A method of mopping a floor comprising: 
 providing a mop assembly for applying liquid to a surface, said assembly comprising:    a mop head;    an elongate handle having a first end pivotally attached to said mop head, an opposite second end, and a portion adjacent said second end adapted to be manually engaged to move the mop head along the surface;    a container for a supply of the liquid separate from the handle and adapted to be supported above the mop head, said container having an opening closed by a closure mechanism through which the container can be refilled;    a valve assembly mounted on said handle adjacent said first end, having an inlet opening and an outlet opening, and having first and second members relatively movable between a closed position to stop the flow of liquid through said valve between said inlet and outlet openings, and an open position allowing the flow of liquid between said inlet and outlet openings;    a flexible hose extending and being connected between said container and said inlet opening of said valve assembly for conveying liquid from said container to said valve assembly; 
 wherein said valve assembly comprises a length of resiliently flexible tubing having an inlet end providing said inlet opening, an outlet end providing said outlet opening, and a portion of said length of tubing between said inlet and outlet ends extending between said first and second members of said valve assembly, said first and second members being positioned to press together opposite sides of said length of tubing in said closed position to stop flow of liquid through said length of tubing, and being spaced apart in said open position to afford separation of the opposite sides of said length of tubing and flow of liquid through the length of tubing;  
   engaging the valve assembly to release liquid onto the floor; and    moving the mop head to spread the liquid over the floor.
