A vacuum cleaner includes a housing, a debris chamber defined within the housing, a filter disposed within the debris chamber, a motor assembly including a motor and an impeller connected to the housing and operable to generate airflow through the debris chamber and filter, a voltage sensor positioned to detect an input voltage applied to the motor, a temperature sensor positioned to detect a temperature associated with the motor and a controller communicatively coupled to the voltage sensor, temperature sensor, and motor. The controller includes a processor and memory having instructions that program the processor to determine a threshold temperature based at least in part on the input voltage detected by the voltage sensor, compare the temperature associated with the motor to the threshold temperature, and output a warning that the filter is full of debris when the temperature associated with the motor exceeds the threshold temperature.
