An apparatus for cleaning a carpet which includes two reservoirs mounted on a frame over the rear wheels of a truck to store a supply of cleaning fluid which is heated in a heat exchanger is disclosed. The reservoirs reduce the sloshing of fluid when the truck is in motion. Pivot flanges are used to balance the reservoirs on the frame to provide effective transfer of the apparatus from one truck to another. The truck engine generates heat energy which is convectively transferred to the engine coolant fluid which is subsequently cycled through the heat exchanger. The cleaning fluid is also transported to the heat exchanger where heat transfer takes place between the cycling engine coolant fluid and the cleaning fluid. The cleaning fluid is heated to a higher temperature condition prior to being sprayed on and into the rug while the engine coolant fluid is cooled prior to being recycled through the engine. A vacuum, enhanced by the flexing movement of the walls of a dirt container or soil tank, provides for suctioning of dirt from the carpet.
