Abstract
A surface cleaning head includes an openable agitator chamber to provide access to an agitator, such as a brush roll, for purposes of removing debris and/or removing the agitator. The openable agitator chamber is covered by an external cover that is movable between an open position and a closed position. A sealing member may be located between the external cover and a surface cleaning head housing and around a perimeter of the agitator chamber. A surface cleaning head includes a removable rotatable agitator, such as a brush roll, which is driven by a drive mechanism that axially engages the driven end. At least one end of the removable agitator may be secured in the agitator chamber by the external cover. The surface cleaning head may also include one or more transparent regions (e.g., on the openable cover) to allow visual inspection of the agitator during use.
