Abstract
Leading and trailing cylindrical brushes (14) are moved in an operation direction to sweep and wet scrub a floor In differing aspects, the trailing cylindrical brush (14) is rotated at a greater rotational speed than the leading cylindrical brush (14) to enhance sweeping ability and preferably in the order of 1500 RPMs to enhance polishing. The brushes (14) include spiraled, equally circumferentially spaced rows (R) of a multiplicity of equally spaced tufts (54). The tufts (54) of an adjacent trailing row (R) are indexed laterally from a leading row (R) by an index distance (T) less than one half of the distance (I) of the tufts (54) in the rows (R).
