High pressure extractor

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.
