Abstract
A bowling lane maintenance machine is operable at different speeds for applying selected lane dressing profiles to the lane and for reducing the time required for performing lane maintenance, including cleaning. In the preferred machine, absorbent wicks are used to transfer lane dressing from a reservoir to an applicator assembly. Lane dressing is recycled through an overflow in the reservoir to maintain a constant level and thereby maintaining a constant transfer rate through the wicks. The preferred machine also includes a cleaning assembly for applying a cleaning liquid to the lane and removing the liquid into a spent liquid storage tank. A vacuum pump induces air flow through the cleaning assembly for removing spent cleaning liquid which subjects the liquid in the tank to foaming. A controller stops the vacuum pump for a selected time in order to allow the foam to settle and then restarts the pump.
