Abstract: In a mobile floor sweeper/scrubber, a closed hydraulic system directs hydraulic fluid, or oil, to power various subsystems, such as the drive, steering, sweeping, scrubbing, etc., subsystems, which results in heating of the hydraulic fluid to an elevated temperature. The heated hydraulic fluid is provided to a heat exchanger, to which is also providing the scrub water for heating the water prior to application to the floor for improved, more efficient cleaning of the floor. This arrangement allows for the use of higher scrub water temperatures without using a dedicated system limited to the generation of higher scrub water temperatures, or without operating the sweeper/scrubber's drive motor at elevated temperatures higher than its specified normal operating temperature. The use of heated or ambient scrub water can be selected as desired by the sweeper/scrubber operator.
