Floor Vacuum Cleaner

Abstract

The invention relates to a floor vacuum cleaner comprising a dust collector arrangement mounted on rollers and/or runners, a suction hose, a suction tube, and a floor nozzle, wherein the floor nozzle is fluidically connected to the dust collector arrangement via the suction tube and the suction hose, wherein the dust collector arrangement comprises a dust separator, wherein the dust collector arrangement comprises a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged so that an air stream suctioned in through the floor nozzle, the suction tube, and the suction hose flows through the motorized fan unit and into the dust separator, wherein the dust collector arrangement has a housing and the motorized fan unit is mounted on or in the housing, wherein the dust separator is mounted in the housing.
