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, also comprising a motorized fan unit for suctioning an air stream through the floor nozzle, wherein the motorized fan unit is arranged between the floor nozzle and the suction tube such that an air stream suctioned in through the floor nozzle flows through the motorized fan unit and into the suction tube.

         4 . The floor vacuum cleaner according to  claim 1 , wherein said suction tube has a diameter in a range from 25 mm to 50 mm and/or a length in a range from 600 mm to 1200 mm. 
     
     
         5 . The floor vacuum cleaner according to  claim 1 , wherein said suction hose has a diameter in a range from 25 mm to 50 mm and/or a length in a range from 1000 mm to 2500 mm. 
     
     
         6 . The floor vacuum cleaner according to  claim 1 , wherein said floor nozzle is configured or said motorized fan unit is arranged such that no contact between a fan wheel and a test probe according to IEC/EN 60335 is possible through said floor nozzle. 
     
     
         7 . The floor vacuum cleaner according to  claim 1 , comprising a blow-out filter. 
     
     
         8 . The floor vacuum cleaner according to  claim 1 , wherein said floor vacuum cleaner is a bag vacuum cleaner. 
     
     
         9 . The floor vacuum cleaner according to  claim 8 , comprising a vacuum cleaner filter bag, where said vacuum cleaner filter bag is a flat bag or a disposable bag. 
     
     
         10 . The floor vacuum cleaner according to  claim 9 , wherein the bag wall of said vacuum cleaner filter bag comprises one or more layers of a nonwoven and/or one or more layers of nonwoven fabric. 
     
     
         11 . The floor vacuum cleaner according to  claim 1 , wherein said floor vacuum cleaner is a bagless vacuum cleaner. 
     
     
         12 . The floor vacuum cleaner according to  claim 11 , wherein said dust collector unit comprises an impact separator or a centrifugal separator. 
     
     
         13 . The floor vacuum cleaner according to  claim 1 , wherein said motorized fan unit is arranged on and/or above said floor nozzle. 
     
     
         14 . The floor vacuum cleaner according to  claim 1 , wherein said motorized fan unit is fluidically connected to said floor nozzle via a tube member. 
     
     
         15 . The floor vacuum cleaner according to  claim 1 , wherein said motorized fan unit comprises radial fan. 
     
     
         16 . The floor vacuum cleaner according  claim 1 , comprising a second motorized fan unit. 
     
     
         17 . The floor vacuum cleaner according to  claim 1 , wherein said floor nozzle comprises no rotating brush.
