Windshield wiper with swivel facility

Normally wiper works from bottom to top, sweeping any dust, dirt. Sometimes if one is not careful to manually remove dirt before operating wiper, there are scratch marks on the glass.

Proposed modification will have swivel function to slightly lift the wiper above glass surface, move to top, spray water to wash out the dirt on glass, lower the wiper to make contact with glass & then operate it.

There will also be provision for compressed air to clean any dirt on wiper surface that remains in contact with glass.
