Abstract: A valve for controlling flow of fluid from an inverted fluid reservoir, the valve comprising: retaining mechanism for coupling the valve to a fluid reservoir; a central fluid opening for flow of fluid from the fluid reservoir through the valve; a valve post slidably disposed within the central fluid opening, the valve post having a sealing portion adapted to seal the central fluid opening and prevent fluid flow through the valve in a closed position; a biasing mechanism coupled to the valve post for biasing the sealing portion of the valve post against the central fluid opening when the valve is in the closed position; and an air vent system.

Abstract: An advanced cleaning system having a handle portion with a proximal end and a distal end, a cleaning head portion, the cleaning head portion adapted for use with a removable cleaning pad, and a cleaning fluid reservoir fluidically coupled to the cleaning head portion such that cleaning fluid is controllably allowed to flow via gravity onto the surface to be cleaned adjacent the cleaning head portion.
