ABSTRACT:
A mop assembly including a mop head and handle, and a supply of liquid connected to a valve assembly on the handle. The valve assembly includes a replaceable length of resiliently flexible tubing having a portion extending transversely through the handle and members on opposite sides of the length of tubing that are relatively movable between a closed position pinching together opposite sides of the tubing to stop the flow of liquid through it, and a spaced open position affording flow of liquid through the tube. A storage cart includes a main portion and a tray portion having a receptacle for receiving the mop head mounted on the main portion for relative movement between a vertical closed position at which the main portion covers an open side of the receptacle; and a horizontal open position at which the mop head can be inserted into or removed from the receptacle.
