ABSTRACT:
An upright vacuum cleaner is provided. The upright vacuum cleaner includes a nozzle base section including a main suction opening formed in an underside thereof. An upright housing section is hingedly connected with the nozzle base section. The housing section includes a cyclonic airflow chamber and a dirt cup for receiving dirt and dust separated by the cyclonic airflow chamber. A hose connects the nozzle base section to the upright section and is selectively detachable from the nozzle base section. The hose communicates an airstream that flows from the main suction opening to airflow chamber. A suction source is located in one of the upright housing section and the nozzle base section and is in fluid communication with the cyclonic airflow chamber. A filter assembly is located in an airflow chamber upstream from the suction source.
