Abstract
A controller for a vacuum cleaner includes a processor and a memory. The memory includes instructions that program the processor to operate a motor at a first power level, receive a temperature of a drive component associated with the motor from a temperature sensor, and compare the temperature of the drive component associated with the motor to a first threshold temperature. The processor operates the motor at a second power level lower than the first power level for a period of time when the temperature of the drive component associated with the motor is greater than or equal to the first temperature threshold, and continues operating the motor at the first power level when the temperature of the drive component associated with the motor is less than the first temperature threshold.
