ABSTRACT:
A street sweeper with vacuumized dust control where a rotary broom chamber surrounds a rotary broom. The rotary broom chamber connects by a conveyor housing containing a conveyor mechanism to a hopper having a powered fan and a filter. A vacuum or low pressure is created within the hopper which communicates through the conveyor housing to the rotary broom chamber which creates an airflow therebetween which carries dust or other light debris to a filter which filters out the dust particles or other light debris. The conveyor housing and other components are positionable to accommodate various modes of operation.
