a second brush extending laterally from the free end of the housing in opposed relation to the brush and rotatable about the rotation axis; and
an air motor, drivable by a stream of air flow through the motor, operatively engaging the brush and the second brush to selectively cause rotation of the brush about the rotation axis.
2. The apparatus of claim 1 further including a debris removal apparatus having a vacuum pressure generatable from the stream of air flow.
3. The apparatus of claim 2 wherein the debris removal apparatus includes a collector member in proximity to but spaced from the brush and the second brush and a cleaning conduit extending between the collector member and the stream of air flow.

5. The apparatus of claim 3 wherein the cleaning conduit extends to an exhaust portion of the stream of air flow, with the exhaust portion being downstream of the air motor.
6. The apparatus of claim 1 wherein the motor is an air motor that is drivable by a stream of air flow through the motor.
7. The apparatus of claim 6 further including a debris removal apparatus having a vacuum pressure generatable from the stream of air flow.
8. The apparatus of claim 7 wherein the debris removal apparatus includes a collector member in proximity to but spaced from the brush and the second brush and a cleaning conduit extending between the collector member and the stream of air flow.
9. The apparatus of claim 8 wherein the air motor includes an exhaust conduit through which the stream of air is directed after passing through the air motor, and the exhaust conduit includes a venturi effect feature, and the cleaning conduit operatively engages the exhaust conduit at the location of the venturi effect feature.
10. An apparatus for cleaning an interior surface of a tubular tool rail extending in a first longitudinal direction and including a slotted opening extending in the first longitudinal direction having a predetermined width normal to the first longitudinal direction, with the interior surface facing away from the slotted opening, the apparatus comprising:
an elongated housing having a free end and a housing body extending in a second longitudinal direction, the housing body including a portion adjacent to the free end that has lateral dimensions small enough to allow rotation about an axis normal to the first longitudinal direction when the portion adjacent to the free end is located in the slotted opening;
a first brush extending laterally from the free end of the housing having a rotation axis that is generally normal to the second longitudinal direction, with the first brush having a diameter that is less than the predetermined width of the slotted opening, and wherein the first brush is contactable with the interior surface when the portion of the elongated housing adjacent to the free end is located in the slotted opening;
a second brush extending laterally from the free end of the housing in opposed relation to the first brush and rotatable about the rotation axis, and the second brush having a diameter that is less than the predetermined width of the slotted opening, and wherein the first brush has a first brush width and the second brush has a second brush width such that a combined width including the first bush width, the second brush width and the free end of the elongated housing is wider than the predetermined width of the slotted opening; and
an air motor, drivable by a stream of air flow through the motor, operatively engaging the first brush and the second brush to selectively cause rotation of the first brush and the second brush about the rotation axis.
11. The apparatus of claim 10 further including a debris removal apparatus having a vacuum pressure generatable from the stream of air flow.
12. The apparatus of claim 11 wherein the debris removal apparatus includes a collector member in proximity to but spaced from the brush and the second brush and a cleaning conduit extending between the collector member and the stream of air flow.
13. The apparatus of claim 12 wherein the collector member has a first dimension that is narrower than the predetermined width of the slotted opening and a second dimension that is wider than the predetermined width of the slotted opening, wherein the collector member is insertable within the slotted opening and rotatable relative to the tubular tool rail while in the slotted opening.
14. The apparatus of claim 12 wherein the air motor includes an exhaust conduit through which the stream of air is directed after passing through the air motor, and the exhaust conduit includes a venturi effect feature, and the cleaning conduit operatively engages the exhaust conduit at the location of the venturi effect feature.
15. An apparatus for cleaning an interior surface of a tubular tool rail extending in a first longitudinal direction and including a slotted opening extending in the first longitudinal direction having a predetermined width normal to the first longitudinal direction, with the interior surface facing away from the slotted opening, the apparatus comprising:
an elongated housing having a tree end and a housing body extending in a second longitudinal direction, the housing body including a portion adjacent to the free end that has lateral dimensions small enough to allow rotation about an axis normal to the first longitudinal direction when the portion adjacent to the free end is located in the slotted opening;
a brush extending laterally from the free end of the housing having a rotation axis that is generally normal to the second longitudinal direction, with the brush having a diameter that is less than the predetermined width of the slotted opening, and wherein the brush is contactabie with the interior surface when the portion of the elongated housing adjacent to the free end is located in the slotted opening;
