An upright vacuum cleaner includes a housing, a nozzle opening in the housing and a dust collector carried on the housing. A suction fan is also carried on the housing. The suction fan draws air, dirt and debris from a surface to be cleaned through the nozzle opening to the dust collector. The upright vacuum cleaner also includes a first rotary agitator and a second rotary agitator, both carried on the housing. A drive motor carried on the housing drives the first rotary agitator through the belt and pulley assembly. A gear drive assembly drivingly connects the first rotary agitator to the second rotary agitator.
