Abstract
A turbo brush for cleaning a surface comprises a housing having an upper surface, a lower surface, a front end and a rear end, the lower end having a dirty air inlet. A primary air flow path extends from the dirty air inlet to a dirty air outlet. A rotary brush is associated with the dirty air inlet and extends transverse to a forward direction of movement of the turbo brush. A drive mechanism comprises an air driven turbine, a drive gear drivingly connected to the rotary brush and a worm gear directly drivingly connecting the air driven turbine and the drive gear.

A turbo brush for cleaning a surface comprising:
- (a) a housing having an upper surface, a lower surface, a front end and a rear end the lower surface having a dirty air inlet;
- (b) a primary air flow path extending from the dirty air inlet to a dirty air outlet;
- (c) a rotary brush associated with the dirty air inlet and extending along a brush axis that is generally parallel to the front end, the rotary brush comprising a first end and an opposing second end that is axially spaced from the first end;
- (d) a drive worm gear that is provided on the rotary brush between the axially opposed first and second ends;
- and,
- (e) a drive mechanism comprising an air driven turbine drivingly connected to a shaft having a worm provided thereon, and the worm directly drivingly engages the drive worm gear
- wherein the front end is spaced from the rear end in a first direction and the air driven turbine has a turbine axis of rotation that is generally parallel to the first direction and is generally orthogonal to the brush axis.
