Abstract
A cleaner unit for carpet and upholstery and the like includes an adjustable power control so that electrical power usage can be set in accordance with available circuit capacity. The cleaner unit includes multiple electrical loads such as a vacuum motor, a pump for delivering a cleaning fluid to a cleaning head or tool, and one or more resistance heaters for heating the cleaning fluid, wherein these loads are adapted for plug-in connection by one or more power cords to a standard domestic power circuit. An ammeter permits the current load to be monitored. In the preferred form, the adjustable power control is associated with one of the resistance heaters and permits the heater current load to be variably set according to the available current capacity of the power circuit.
