Abstract
Disclosed is a dispenser (10) for use with an automatic floor scrubbing machine (75), and a method for cleaning a floor. The dispenser (10) has a solid chemical (13) which is dissolved by water spray from a spray nozzle (21). The detergent solution is then directed by a conduit (25) to a scrub brush (85). A water reservoir (83) provides water for the detergent solution, and a valve (38) directs water to a rinse conduit (37) for rinsing of the floor. After cleaning, the dirty water or detergent solution is carried through conduit (36) to a recovery tank (84).
