Claim Text:
1. A vacuum cleaner agitator system comprising: a housing; an inlet nozzle through a lower surface of the housing; an agitator chamber in the housing adjacent to and in fluid communication with the inlet nozzle; a rotary agitator comprising: a cleaning blade comprising a linear contact surface extending along the longitudinal direction, the cleaning blade being mounted to the housing adjacent the spindle and movable between a first position in which the contact surface is spaced from the one or more friction surfaces when the spindle rotates, and a second position in which the contact surface engages the one or more friction surfaces when the spindle rotates; wherein the one or more friction surfaces and the agitating devices are spaced about a circumference of the spindle a sufficient distance to prevent the agitating devices from being pinched between the one or more friction surfaces and the linear contact surface when the cleaning blade is in the second position and the agitator is rotated in at least one direction.
