摘要：
A dirt collection and separation module can include a suction air flow around the perimeter of a tank to ingest fine dust that becomes airborne during the emptying process. Additionally, a trash can suction nozzle around a rim, a hand vacuum docking station, and an auxiliary suction nozzle that can fluidly couple the hand vacuum.
