Abstract
A floor cleaning apparatus includes a body having a suction inlet and an exhaust outlet. A dirt cup assembly is carried on the body. The dirt cup assembly includes a primary cyclone, a plurality of secondary cyclones and an airflow path between the primary cyclone and the plurality of secondary cyclones. A suction generator is carried on the body. The suction generator moves an airstream through the suction inlet, the airflow path of the dirt cup assembly and the suction outlet. The airflow path is characterized by a primary air guide including an airflow surface that provides for laminar airflow between the secondary cyclones.
