Abstract: A convertible sweeper has a main rotating cylindrical brush and a second rotatable cylindrical tool. The second tool is movable between a first position in front of the main brush where it rotates to assist in very effectively loading debris comprised mainly of dry leaves, paper, etc. into the hopper, and a second position in the upper part of the hopper entrance. There it may be held stationary when the debris to be swept is mainly sand, which is very efficiently swept by the main brush alone, or it may be rotated if the debris also includes some light material, because such rotation assists to a degree in loading that material.

Abstract: This invention is concerned with a machine in the nature of a scrubber for removing dirt, grime, etc. from a surface to be cleaned and includes a mobile machine with a scrub brush mounted for rotation about a generally vertical axis with a housing therefor which is pivotally mounted and concentric with the scrub brush drive. The brush, brush drive, brush housing and squeegees which are mounted on the brush housing, also make up a brush head assembly that is raised and lowered as a unit.
