Abstract
A surface cleaning apparatus can include a housing adapted to move across a surface to be cleaned, an edge brush, and a brushroll driven by a brush motor. The edge brush is connectable with a drive coupling for rotating the edge brush, and is indirectly driven by the brush motor via the brushroll. In one aspect, the edge brush and drive coupling comprise a modular unit removably coupled to the housing. In another aspect, the drive coupling can include a worm and a belt.
