Abstract
A cleaning head for a floor cleaner including a housing, a brushroll, a suction inlet, and a mounting plate.

The edge brush is configured to direct dirt and debris from the lateral side of the floor cleaner to the suction inlet.
Claims23
A floor cleaner comprising:
- a housing including a front side, a rear side, a top side, a bottom side, a first lateral side, and a second lateral side;
- a suction source;
- a brushroll chamber having an opening in the bottom side of the housing, the opening having a front edge, a rear edge, a first lateral edge, and a second lateral edge;
- a brushroll mounted in the brushroll chamber extending in a longitudinal direction between the first and second lateral edges and extending through the opening to contact a surface to be cleaned;
- a suction inlet formed between the brushroll and the rear edge;
- a recovery tank in fluid communication with the suction source and the suction inlet, the recovery tank configured to contain debris drawn by the suction source through the suction inlet from the surface to be cleaned;
- and
- an edge brush adjacent the bottom side of the housing, the edge brush having a first end, a second end, and a row of bristles between the first end and the second end,
- wherein the first end of the edge brush is adjacent the suction inlet and the second end of the edge brush is adjacent the first lateral side of the housing forward of the suction inlet, and
- wherein the edge brush extends in a diagonal direction relative to the longitudinal direction of the brushroll, extending in a direction along a plane which is parallel to the bottom side of the housing and also in a diagonal direction relative to a direction perpendicular to the longitudinal direction of the brushroll.
