20090126144 | PROTECTANT APPLICATION - A portable surface cleaning apparatus has a first tank connected to the housing and with a body of a liquid protectant composition therein, a second tank mounted to the housing with a body of water therein, and a fluid delivery system with an inlet in fluid communication with each of the first and second tanks and an outlet in fluid communication with a spray nozzle for spraying a mixture of the liquid protectant and water onto a surface. | 05-21-2009 |
20090126800 | 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. | 05-21-2009 |
