AbstractAn apparatus for producing heated water, including steam, to be used as a cleaning fluid, includes an internal combustion engine, a water heating assembly, a vacuum generating device, a cleaning assembly and a dirty water collector. The heating assembly includes piping and three heat exchangers. Two of the heat exchangers are located to receive exhaust gas directly from exhaust ports respectively of the engine. The third heat exchanger receives a mixture of gas which includes residual exhaust gases from the first and second heat exchangers and the output of the vacuum generator. Water is preheated in the third heat exchanger and finally heated in the first and second heat exchangers. The heated water is used at the cleaning assembly and partially reclaimed by the vacuum generator. Condensed water and dirt are collected in the collector and water vapor is further heated by and passed through the vacuum generator to the third heat exchanger.
