Embodiments of the invention relate to an attachment for a pressure washer to facilitate cleaning of secondary surfaces. The attachment includes a body with three walls, two of the walls are in a parallel relationship and a third wall is substantially perpendicular to the two parallel walls. A single rolling element is in communication with the two parallel walls and spaced apart from the third wall. The single rolling element may be applied to a secondary surface so that the attachment rolls along the surface thereof while liquid is ejected from the pressure washer to clean the secondary surface.

1. An apparatus comprising: a first body having first and second oppositely disposed walls, and a third wall substantially perpendicular to the second and second walls;an aperture formed in the third wall and adapted to receive a spray nozzle;a first rolling element extending between the first and second walls and substantially oppositely disposed to the third wall, and including a first guide post in communication with the first wall and a second guide post in communication with the second wall, the first and second guide posts extending distally from the position of the first rolling element;an open area formed between the first and second walls, the open area extending from the third wall to the rolling element;the aperture to support freedom of movement of the spray nozzle within the aperture with discharge of a spray from the nozzle extending along a range defined by the open area; andthe first rolling element adapted to be applied to a secondary surface between the first and second guide posts, including the first guide post in communication with a first side wall area of the secondary surface and the second guide post in communication with a second side wall area of the secondary surface, with the first and second side wall areas being in a substantially parallel arrangement. 2. The apparatus of claim 1, wherein the first and second walls have a first height adjacent to the rolling element and a second height adjacent to the third wall, including the first height being less than the second height. 3. The apparatus of claim 2, further comprising the spray nozzle coupled to the aperture, wherein a trajectory of a liquid discharged from the spray nozzle extends above the first height. 4. The apparatus of claim 1, wherein a straight position of the spray nozzle in the aperture causes the spray discharge to extend over a top surface of the rolling element. 5. The apparatus of claim 1, further comprising a second body secured to the first body, the second body having an extended position and a retracted position. 6. The apparatus of claim 5, further comprising a recess formed in the first body to receive the second body in the retracted position. 7. The apparatus of claim 6, further comprising the second body having two oppositely disposed walls and a second rolling element extending between the two oppositely disposed walls. 8. The apparatus of claim 7, further comprising the recess to receive the second rolling element in the retracted position. 9. The apparatus of claim 7, further comprising the first rolling element parallel to the second rolling element. 10. The apparatus of claim 7, further comprising a secondary set of guide posts in communication with the second body and extending distally from the second rolling element. 11. The apparatus of claim 10, further comprising the second body in an extended position and the second rolling element to be applied to the secondary surface, and the secondary surface having a width equal to or less than a distance between the two oppositely disposed walls of the second body. 12. The apparatus of claim 7, further comprising an aperture formed in one of the two oppositely disposed walls and a locking spring in communication with the aperture, the locking spring to engage the aperture and hold the second rolling element in a fixed position. 13. An apparatus comprising: a first body having first and second oppositely disposed walls, and a third wall substantially perpendicular to the second and second walls;an aperture formed in the third wall;a shaft extending between the first and second walls and substantially oppositely disposed to the third wall;the shaft being a single body have a first end and a second end spaced between the first and second walls, with the first end in relative communication with the first wall and the second end in relative communication with the second wall;a rolling element substantial concentric to the shaft and to extend around an exterior circumference of the shaft, the rolling element to rotate along a first axis, the first axis substantially perpendicular to the third wall; anda first guide post in communication with the first wall and a second guide post in communication with the second wall, the first and second guide posts extending distally from the position of the rolling element. 14. The apparatus of claim 13, further comprising the first rolling element adapted to be applied to a secondary surface between the first and second guide posts, including the first guide post in adjacently positioned with a first side wall area of a secondary surface and the second guide post adjacently positioned with a second side wall area of the secondary surface, with the first and second side wall areas being in a substantially parallel arrangement. 15. The apparatus of claim 14, further comprising a second body secured to the first body, the second body having two oppositely disposed walls and a second rolling element extending between the two oppositely disposed walls. 16. The apparatus of claim 15, further comprising the second body having an extended position, wherein the extended position includes the first rolling element parallel to the second rolling element. 17. The apparatus of claim 15, further comprising the second body having a retracted position, including a recess in the first and second walls of the first body adapted to receive and secure the two oppositely disposed walls of the second body. 18. The apparatus of claim 15, further comprising a secondary set of guide posts in communication with the second body and extending distally from the second rolling element. 19. The apparatus of claim 14, further comprising the second body in an extended position and the second rolling element to be applied to the secondary surface, and the secondary surface having a width equal to or less than a distance between the two oppositely disposed walls of the second body. 20. The apparatus of claim 15, further comprising an aperture formed in one of the two oppositely disposed walls and a locking spring in communication with the aperture, the locking spring to engage the aperture and hold the second rolling element in a fixed position.
