ABSTRACT:
Disclosed herein is a floating brush floor cleaner characterized in that a plurality of brushes are pivotally connected to the bottom face of a floor polishing machine. The manner in which these plural brushes are connected thereto provide independent action for each of the brushes to conform to the contour of the surface to be cleaned and includes a brush portion, a steel band nested around the brush, angle irons fastened to the top face of the brush, and a connection link between the bottom of the floor cleaning machine shroud or steel plate and the brush so that each brush is independently connected and capable of tracking an uneven contour of the floor.
