PROTECTANT APPLICATION
A hand-held nozzle is attached to the end of a vacuum and fluid delivery hose of an upright deep cleaner. The nozzle includes a reservoir to contain a solution to be applied to a surface. When a solution delivery system of the deep cleaner is pressurized, water from the upright cleaner clean water tank is routed through the hose to the hand-held nozzle. The water is routed through a venturi valve connected to the reservoir, which draws the solution to the valve to mix with the water stream. The resultant mixture flows from the hand-held nozzle for application to a surface being treated. One embodiment of the solution reservoir includes a retainer cap bonded to the reservoir and utilizing a bayonet-type mounting arrangement for mounting the reservoir to a nozzle assembly.
1 . A method of applying a liquid protectant solution to a surface comprising the steps of:
placing the liquid protectant solution into a dispensing tank in an extraction cleaning machine which includes the dispensing tank, a dispenser for applying a solution to a surface to be cleaned in fluid communication with the dispensing tank, and wherein the extraction cleaning machine further includes a liquid recovery system for recovering soiled liquid from a surface on which a liquid cleaning solution had been applied;
dispensing the liquid protectant solution in the dispensing tank onto the surface through the dispenser.
2 . A method of applying a liquid protectant solution to a surface according to claim 1 wherein the surface is a carpet surface and the act of dispensing the liquid protectant takes place as the extraction cleaning machine is moved over the surface.
3 . A method of applying a liquid protectant solution to a surface according to claim 2 and further comprising the step of disabling the liquid recovery system prior to the dispensing step.
