Abstract: Apparatus movable over an approach surface and down a lane surface includes a shield plate which has a forward edge positionable to prevent cleaning fluid from nozzles from reaching the approach surface behind a foul line while permitting cleaning of the lane surface beyond the foul line. A pair of forward wheels are used for support during movement over the approach surface and are arranged to drop down into side gutters to engage support rollers with the lane surface and to also drop a fluid pick-up head into engagement with the approach surface at the foul line.
