1. A floor cleaning device comprising:
- a base;
a cleaning fluid supply tank carried by the base;
a source of pressure communicating with the cleaning fluid supply tank that pressurizes a cleaning fluid held in the cleaning fluid supply tank to a pressure above atmospheric pressure;
a fluid delivery system which delivers pressurized cleaning fluid from the cleaning fluid supply tank to a surface to be cleaned;
a heater which heats the cleaning fluid before it exits said fluid delivery system, the heater operating at a first power level in a warm-up phase and at a second power level, lower than the first power level, in an operational mode;
a suction source supported by the base and separate from the source of pressure; and
a control system which controls delivery of power to the suction source and the heater, wherein in the warm-up phase, the control system controls delivery of power to the pressure source for pressurizing the cleaning fluid supply tank.
