Abstract: A surface cleaning appliance having a cleaner head that includes an agitator and a motor for driving the agitator. The appliance includes a switch coupling the motor to a supply voltage, a voltage sensor for measuring the magnitude of the supply voltage, a current sensor for measuring the magnitude of current through the motor, and a controller configured to output a PWM signal for controlling the switch. The controller then adjusts the duty cycle of the PWM signal in response to changes in the supply voltage and in response to changes in the current through the motor.

Abstract: A vacuum cleaner that includes a suction source, a cleaner head, and a controller. The suction source includes an impeller and a first motor for driving the impeller, and the cleaner head includes an agitator and a second motor for driving the agitator. The controller is configured to generate control signals for controlling simultaneously the excitation of the first motor and the second motor.
