6. The remote-controlled vehicle of claim 5 wherein a tip of the vacuum hose is connected to an interchangeable accessory comprising a vacuum hose positioner, wherein the at least one mechanical power receptor of the vacuum hose positioner is connected to a gear assembly having a first gear configured to provide lateral movement to the tip of the vacuum hose.

7. The remote-controlled vehicle of claim 6 wherein the vacuum hose positioner further comprises another mechanical power receptor connected to a second gear configured to provide tilting movement to the tip of the vacuum hose.

8. The remote-controlled vehicle of claim 1 wherein the platform for supporting each of the distinct interchangeable accessory comprises a universal quick-disconnect assembly for enabling a user to manually mount and dismount each interchangeable accessory from the platform.

9. The remote-controlled vehicle of claim 1 further comprising at least one sensor positionable to monitor any of the interchangeable accessories while performing the distinct operational tasks.

10. The remote-controlled vehicle of claim 1, wherein said vehicle is dimensioned and configured to travel through gaps as small as approximately 0.75 inch in height.

11. The remote-controlled vehicle of claim 1, wherein the interchangeable accessory comprises a gripper, wherein said gripper comprises at least one pair of arms for grabbing an object, the arms connected to a gear assembly having a first gear responsive to mechanical power received through the mechanical power receptor.

12. The remote-controlled vehicle of claim 11 wherein the gripper further comprises another mechanical power receptor connected to a second gear configured to provide tilting movement to said arms.

13. The remote-controlled vehicle of claim 1, wherein the interchangeable accessory comprises a brush assembly having at least one brush connected to a gear assembly having a first gear for rotating in a desired angular direction in response to mechanical power received through the mechanical power receptor.

14. The remote-controlled vehicle of claim 13 wherein the brush assembly further comprises another mechanical power receptor connected to a second gear to provide tilting movement to said brush.

15. A platform for performing a plurality of tasks, the platform comprising:

an interchangeable accessory selected from a set of distinct interchangeable accessories, each distinct interchangeable accessory configured to perform a distinct operational task, the platform comprising at least one mechanical power takeoff, each accessory comprising at least one mechanical power receptor configured to interface with the at least one mechanical power takeoff for coupling mechanical energy to the accessory, the platform constituting a universal platform for the set of distinct interchangeable accessories.

16. The platform of claim 15 further comprising a containment pan, wherein the containment pan is responsive to a motorized gear to be selectably movable upwardly and downwardly in a gap through which the platform may travel.

17. The platform of claim 15 further comprising a compartment including a vacuum cleaner responsive to a pressurized air source to create a Venturi-induced vacuum, wherein the compartment further comprises confined volume for accumulating debris collected in response to suction created by the vacuum cleaner in a vacuum hose connected thereto.

18. The platform of claim 15 wherein a tip of the vacuum hose is connected to an interchangeable accessory comprising a vacuum hose positioner, wherein the at least one mechanical power receptor of the vacuum hose positioner is connected to a gear assembly having a first gear configured to provide lateral movement to the tip of the vacuum hose, wherein the vacuum hose positioner further comprises another mechanical power receptor connected to a second gear in the gear assembly configured to provide tilting movement to the tip of the vacuum hose.

19. The platform of claim 15 wherein the platform for supporting each of the distinct interchangeable accessory comprises a universal quick-disconnect assembly for enabling a user to manually mount and dismount each interchangeable accessory from the platform.

20. The platform of claim 15 further comprising at least one sensor positionable to monitor any of the interchangeable accessories while performing the distinct operational tasks.
