Abstract
An apparatus for cleaning floors which recycles waste heat and water to provide greater efficiency. An internal combustion engine is used to power the apparatus. Heat from the engine's lubricant is used to heat the wash solution applied to the floor. Heat from the engine's cooling air, radiator, and catalytic converter is used to dry the cleaned floor. A drying brush is also used to accelerate drying. Used rinse water is recycled for use as wash solution. Exhaust from the engine is used to preheat the floor to be cleaned. The engine may be used to propel the apparatus.
