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.
Claims20
A surface cleaning apparatus, comprising:
- a housing adapted to move across a surface to be cleaned;
- a brush motor;
- a brushroll rotatable about a brushroll axis, wherein the brushroll is operably coupled to and driven the brush motor;
- and
- a modular unit removably coupled to the housing, the modular unit comprising:
- an edge brush comprising an attachment hub rotatable about a rotational axis and a cleaning implement configured to contact the surface to be cleaned;
- and
- an edge brush drive coupling to operably couple the edge brush with the brushroll, the edge brush drive coupling comprising:
- a gear train operably coupleable with the brushroll;
- and
- a gear casing housing the gear train.
A surface cleaning apparatus, comprising:
- a housing adapted to move across a surface to be cleaned;
- a brush motor;
- a brushroll rotatable about a brushroll axis, wherein the brushroll is operably coupled to and driven the brush motor;
- and
- an edge brush mounted on the housing, wherein the edge brush is operably coupled to and driven the brush motor, the edge brush comprising:
- an attachment hub rotatable about a rotational axis that is substantially perpendicular to the brushroll axis;
- and
- a cleaning implement configured to contact the surface to be cleaned;
- and
- a drive coupling between the attachment hub and the brushroll comprising:
- a worm operably coupled with brushroll for rotation therewith;
- a two-stage gear having a first gear enmeshed with the worm and a second gear coupled with the first gear for rotation therewith;
- and
- a belt coupled with the second gear to transmit the rotational force of the two-stage gear to a driven gear coupled with the attachment hub of the edge brush.
