  • Publication number: 20060021184
    Abstract: A motor and brushroll mounting system for a cleaning device. The mounting system includes a motor, an agitator, a drive system, and a bracket. The motor has a rotary driving component adapted to rotate about a drive axis centerline, and a motor housing. 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.
