Abstract
A surface cleaner includes a base housing assembly defining an agitator chamber, and includes an end cap, a bearing disposed axially adjacent to the end cap, and an agitator rotatably supported on the bearing for rotation about an axis of rotation in the agitator chamber. The end cap and the agitator define an axial gap between an axial end of the agitator and the end cap. The surface cleaner includes a motor shaft spaced apart from the agitator, a drive belt operatively connecting the motor shaft and the agitator, and a motor connected with the motor shaft and operable to rotatably drive the agitator via the motor shaft and drive belt. The surface cleaner includes an impeller blower mounted on the motor shaft, and a conduit system at least partially defining an air channel directing air blown by the impeller blower into the axial gap.

A surface cleaner configured for movement across a surface to be cleaned, the surface cleaner comprising:
- a base housing assembly defining an agitator chamber;
- an end cap;
- a bearing disposed axially adjacent to the end cap;
- an agitator rotatably supported on the bearing for rotation about an axis of rotation in the agitator chamber, the end cap and the agitator defining an axial gap between an axial end of the agitator and the end cap;
- a motor shaft spaced apart from the agitator;
- a drive belt operatively connecting the motor shaft and the agitator;
- a motor connected with the motor shaft and operable to rotatably drive the agitator via the motor shaft and drive belt;
- an impeller blower mounted on the motor shaft;
- and
- a conduit system at least partially defining an air channel directing air blown by the impeller blower into the axial gap.
A surface cleaner configured for movement across a surface to be cleaned, the surface cleaner comprising:
- a base housing assembly defining an agitator chamber;
- an end cap;
- wherein the end cap defines at least one opening extending therethrough;
- a bearing disposed axially adjacent to the end cap;
- an agitator rotatably supported on the bearing for rotation about an axis of rotation in the agitator chamber, the end cap and the agitator defining an axial gap between an axial end of the agitator and the end cap;
- a motor shaft spaced apart from the agitator;
- a motor connected to the motor shaft;
- an impeller blower operatively connected to the motor and mounted on the motor shaft;
- and
- a conduit system at least partially defining an air channel directing air blown by the impeller blower through the at least one opening in the end cap into the axial gap;
- wherein the at least one opening in the end cap is configured to direct the blown air at least partially in an axial direction into the axial gap.
