Abstract
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.

The agitator has a rotary member having a driven component and at least one agitator, and at least one fixed member. The rotary member is rotatably held by the fixed member such that it is rotatable about a driven axis centerline. The drive system operatively connects the driving component and the driven component. The bracket is attached at a first end to the motor housing and at the second end to the at least one fixed member, and extends substantially directly therebetween to substantially prevent relative translation between the drive axis centerline and the driven axis centerline. A cleaning device nozzle and an alignment bracket are also provided.
