Abstract
In accordance with the present invention, an apparatus is provided wherein cleaner is applied to all or a portion of the lane and the cleaner, oil and other residue is picked up by a vacuum head trailing the cleaner applicator in one trip from the foul line to the pit leaving the lane clean and dry. The cleaner can be applied either by means of an applicator pad or by a sprayer. If desired, the cleaning operation can be limited to the last forty-five feet or so, since it is generally desirable to clean this portion of the lane more often than the front portion. On the return or reverse movement of the stripper, no cleaning operations are undertaken but cleaner may be permitted to flow from the cleaner storage tank to the applicator so that the applicator will have sufficient cleaner in it for the beginning of application on the next lane. A mechanism is provided for bowing the vacuum head so that the center is lower than the side edges so that it conforms generally to the concave shape of a bowling alley. A waste tank is provided with appropriate baffles to separate the waste liquid and solids from an air stream created by a vacuum motor attached to the outlet of the waste tank.
