A device with two or more regions configured to clean or treat a working surface is disclosed. Preferably, the device is an oral-care device with a power cleaning head. The power cleaning head comprises two or more regions, wherein at least one of the regions is configured to move and wherein at least one of the regions comprises a squeegee element. Preferably, the regions are configured to independently rotate, oscillate, vibrate or otherwise move while cleaning teeth and gums and can each include bristles, nodules, squeegee elements, or any combination thereof.

What is claimed is: 1. A device comprising: a) a cleaning head, the cleaning head comprising: i) a center region with at least one first squeegee element configured to treat a working surface, the first squeegee element being curved and extending across a width of the center region; and ii) elongated side regions flanking the center region, wherein the side regions each include bristles and respective second squeegee elements configured to simultaneously treat the working surface, the second squeegee elements having a generally serpentine shape and extending along the length of the respective side region; and b) a motorized handle coupled to the cleaning head and which is configured to move the center region and the side regions in a linear back-and-forth motion, the motion of the center region being generally transverse to the curved first squeegee element and the motion of the side regions being substantially parallel to that of the center region and along the length thereof. 2. The device of claim 1, wherein the center region further comprises bristles. 3. The device of claim 1, wherein that at least one of the center region and side regions is further configured to vibrate. 4. The device of claim 1, wherein the first squeegee element comprises curved top wiping squeegee edges. 5. The device of claim 1, wherein the second squeegee elements of the side regions comprise curved top wiping edges. 6. The device of claim 1, wherein a portion of the first squeegee element is contoured. 7. The device of claim 1, further comprising nodules protruding from the cleaning head. 8. The device of claim 1, wherein the first and second squeegee elements are independently made of silicon, latex, rubber or polyurethane. 9. The device of claim 1, wherein the first and second squeegee elements independently have a hardness of between about 10 to 100 Shore A. 10. The device of claim 1, wherein the first squeegee element includes an abrasive material. 11. The device of claim 1, wherein the second squeegee element includes an abrasive material. 12. The device of claim 1, wherein a contact edge of the first squeegee element is planar, v-shaped, concave, diagonally contoured or pointed. 13. The device of claim 1, wherein a contact edge of the second squeegee element is planar, v-shaped, concave, diagonally contoured or pointed. 14. The device of claim 1, wherein the side regions and the center region move independently from one another. 15. The device of claim 1, wherein the center region and the side regions move in opposite directions. 16. The device of claim 1, wherein the center region and the side regions move at different frequencies. 17. The device of claim 1, wherein the cleaning head is detachable from the motorized handle. 18. The device of claim 1, wherein one or more of the center region and the side regions vibrate. 19. The device of claim 1, wherein the first squeegee element is surrounded by bristles. 20. The device of claim 1, wherein the first squeegee element is flanked by bristles.
