VACUUM CLEANER MOTOR ASSEMBLIES AND METHODS OF OPERATING SAME

Abstract:

A vacuum cleaner includes a housing, a debris chamber defined within the housing, a motor assembly connected to the housing and operable to generate airflow through the debris chamber, and a controller communicatively coupled to the motor assembly. The motor assembly includes a motor and an impeller. The controller includes a processor and a memory. The memory includes instructions that program the processor to operate the motor to cause the impeller to generate airflow through the debris chamber, detect an alert condition, and generate a human perceptible audible alert in response to the detected alert condition.
