ABSTRACT:
The present invention provides a walk-behind mobile sweeper for cleaning dust and collecting garbage from surfaces. The sweeper has a motorized cart maneuverable by a human operator, a flow-through collection apparatus supported on the cart for collecting garbage therein, a suction inlet located forwardly of the collection apparatus and a vacuum blower for creating air suction, the vacuum blower drawing garbage and dust via suction through the suction inlet and into the collection apparatus, wherein the vacuum blower is positioned downstream of the container such that garbage does not enter the vacuum blower. The walk-behind mobile sweeper is easily maneuverable, is compact and not only cleans dust and dirt from surfaces but also collects garbage which is further compacted or compressed within a bag. The sweeper can be configured not only as a walk-behind sweeper but also as a stand-on skateboard sweeper or as a ride-on sweeper.
