Patent ID: 7774895

Claim:
A kit for cleaning a surface to be cleaned comprising: a cleaning solution that is adapted to remove soil from the surface to be cleaned and an extraction cleaner having: a housing; a cleaning solution dispensing system mounted to the housing and comprising a cleaning solution tank for storing a quantity of the cleaning solution, a fluid delivery nozzle and a fluid conduit between the cleaning solution tank and the fluid delivery nozzle to dispense the cleaning solution to the surface to be cleaned; a fluid recovery system mounted to the housing for recovering soiled cleaning solution from the surface to be cleaned and including a suction nozzle, a recovery tank and a suction source in communication with the suction nozzle and the recovery tank for drawing dirty liquid from the surface to be cleaned and for depositing it in the recovery tank; and an exothermic heating system adapted to be placed in heat exchange relationship with the cleaning solution dispensing system to heat the cleaning solution to a temperature above room temperature for application to the surface to be cleaned; wherein the exothermic heating system comprises at least one reagent that is adapted to generate an exothermic reaction, and wherein, when the cleaning solution is added to the cleaning solution dispensing system, the exothermic heating system is placed in heat exchange relationship with the cleaning solution dispensing system and the exothermic heating system is activated to generate an exothermic reaction, the cleaning solution is heated, whereby the cleaning solution thus heated can be applied to a surface to be cleaned for enhanced cleaning.
