A vacuum cleaner includes a housing having a hammerhead-shaped nozzle assembly with an agitator cavity formed in the nozzle assembly. An agitator is received in the agitator cavity and an agitator drive motor is held in that agitator. A suction fan is driven by a separate suction fan drive motor carried on the housing. An airflow pathway extending through the agitator and over the agitator drive motor communicates with a suction intake port leading to the suction fan. A light source may also be provided in the housing so that the airflow pathway directs air over the light source. A temperature sensor may also be provided in the airflow pathway between the agitator drive motor and the suction intake port. A method of cooling a light source and/or drive motor is also disclosed.
