摘要： A machine and method for removing coatings and/or membranes from the surface of a floor or the like, which may be uneven, and also conditioning a floor so that it more readily acccepts a new coating. The machine takes the form of a driver member or element which may be abrasive or which may apply or work free abrasive particles against a floor with a controlled application rate that may be related to floor conditions and travel speed of the machine over the surface.

摘要： 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.
