Abstract
A bowling lane maintenance machine (10) performs selected maintenance operations on the surface of the bowling lane, shifts itself to the approach area spanning a plurality of lanes behind the foul line end of the lanes, indexes to another lane, and then shifts to the lane to again perform a maintenance operation thereon. The machine (10) includes structural housing (12) cleaning maintenance assembly (14), propulsion assembly (16), and electronic control system (18); which cooperate for controlled maintenance operations as described above.
