Abstract
A cleaning system including a motor configured to provide rotational energy to an impeller, a current sensor configured to sense current provided to the moto, and a controller having an electronic processor. The controller is configured to receive, from the current sensor, a current signal indicative of the current provided to the motor, filter the current signal to produce a filtered current signal, and control the motor based on the filtered current signal.
