ABSTRACT:
A vacuum cleaner includes a nozzle, an air-filtering dirt receptacle, and a motor. A fan is configured to be driven by the motor to drive a flow of air that carries dirt from a surface through the nozzle and into the receptacle to clean the surface. A controller is configured to provide a notification to a user when the speed of the motor exceeds a threshold value.
