Abstract:
An upright vacuum cleaner includes a nozzle base having a main suction opening formed in an underside thereof. A housing is hingedly connected to the nozzle base. The housing includes a dirt separation chamber and a dirt receptacle for receiving dirt and dust separated by the dirt separation chamber. A conduit connects the nozzle base to the housing. A suction source is located in one of the housing and the nozzle base. The suction source is in fluid communication with the dirt separation chamber. A generally conically shaped filter extends into the dirt separation chamber along a longitudinal axis of the dirt separation chamber.
