ABSTRACT:
A cleaning system utilizes heat from an internal combustion engine to heat cleaning liquid which is sprayed onto a surface to be cleaned. The internal combustion engine drives a vacuum pump which withdraws air and cleaning liquid through a vacuum nozzle for retrieving cleaning liquid and soil. The heated air leaving a vacuum pump is combined with heated exhaust gasses from said engine and heat from the mixture is extracted to heat the cleaning liquid. The cleaning liquid may be further heated by heat extracted from the engine by a cooling system.
