Patent number: 7774895Abstract: An extraction cleaning machine comprising dispensing and recovery systems, the dispensing system including a system for generating heat with an exothermic reaction upon activation for heating the cleaning solution prior to dispensing of the cleaning solution onto a surface. The cleaning solution dispensing system comprises a cleaning solution reservoir to which the heat of the exothermic reaction can be added and a dispenser. The heat of the exothermic reaction can also be added in line to the cleaning solution between the cleaning solution reservoir and the dispenser. The recovery system includes a suction nozzle, a recovery tank and a vacuum source for drawing recovered liquid from the suction nozzle into the recovery tank. A method of cleaning a surface comprises the steps of heating a cleaning solution by an exothermic chemical reaction, applying the cleaning solution to the surface and recovering the cleaning solution from the surface.Type: GrantFiled: December 19, 2006Date of Patent: August 17, 2010Assignee: Bissell Homecare, Inc.Inventors: Eric J.

Patent number: 6880199Abstract: An upright extraction cleaning machine comprises a base module, an upright handle pivotally mounted to the base module, a cleaning solution dispensing system for depositing a cleaning solution on a surface to be cleaned, and a fluid recovery system for recovering expended cleaning solution from the surface to be cleaned. The cleaning solution dispensing system includes at least one tank for holding solution to be dispensed and the recovery system includes a tank for holding recovered solution. Each of the tanks comprises a flexible bladder that is collapsible when empty and will expand as it is filled by the respective fluid. In one embodiment, the upright extraction cleaning machine further comprises additional tanks for holding detergent and carpet treatment to be dispensed. In a further embodiment, the additional tanks for detergent and carpet treatment each comprise a flexible bladder.Type: GrantFiled: September 30, 2002Date of Patent: April 19, 2005Assignee: BISSELL Homecare, Inc.Inventors: Eric C.
