Abstract
A vacuum sweeper vehicle has a sweeper body including a frame. A pair of front wheels are supported by an axle apparatus at a forward end of the sweeper body. The axle apparatus is constructed to provide a space between the front wheels. A pair of rear wheels are supported at a rearward end of the sweeper body. A container is coupled to the sweeper body for receiving debris. A suction hose extends between the container and a vacuum nozzle proximal a forward end of the body. The suction hose extends through the space between the the front wheels. A suction device draws the debris from the nozzle, into the container, and a brush coupled to a forward end of the sweeper body sweeps debris from a ground surface.
