Abstract
A vacuum cleaner including a suction fan and a suction fan drive motor also includes a power control circuit with a controller, and a reset toggle. First and second capacitors are positioned with one on each side of the reset toggle. A zener diode is also provided. Together, the capacitors and zener diode function to reduce the susceptibility of the power control circuit to undesired reset in response to relatively small and otherwise insignificant power supply and static discharge spikes.
