    Abstract: A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.
