Abstract
A cleaning system including a motor configured to provide rotational energy, a current sensor configured to sense current provided to the motor, 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.

A cleaning system comprising:
- a motor configured to provide rotational energy to an impeller;
- a current sensor configured to sense current provided to the motor;
- and
- a controller having an electronic processor, the controller configured to
- receive, from the current sensor, a current signal indicative of the current provided to the motor,
