ABSTRACT:
An industrial scrubbing machine is provided including a foam and spray suppressor in the detergent solution recovery system. The foam suppressor decreases the velocity of the detergent solution as it is drawn from the floor back into the apparatus by the squeegee. The decrease in velocity of the detergent solution allows the solution to be redeposited in the scrubbing apparatus with a minimum of agitation, thus suppressing the tendency of the detergent solution to foam and form spray. The apparatus may have a foam filter in the solution recovery tank to assist in controlling foam development and movement. Further, the apparatus may have spray nozzles to apply a mist to break foam that has developed.
