Surface cleaner with suction and simplified operation

Abstract

A surface cleaner with suction and simplified operation, which can be moved by hand using a push bar ( 30 ) over a cleaning surface on the floor, and consists of a pot-shaped housing ( 6 ) that is open towards a cleaning surface, in which housing at least one rotor arm ( 7 ) having spray nozzles ( 10 ) attached to it is driven to rotate under the action of a high-pressure medium, wherein a manually operated valve device ( 1, 3, 25, 26 ) is present, which supplies the high-pressure medium selectively to one or more rotor arms ( 7 ) and/or to the suction device ( 8 ), wherein, for two-handed operation, the manually operated valve device consists of two spatially separated operating handles ( 1, 3 ) with manually operated operating levers ( 25, 26 ), which are arranged at the two ends of the push bar ( 30 ) of the surface cleaner.

1 . A surface cleaner with suction and simplified operation, which can be moved by hand using a push bar over a cleaning surface on the floor, and consists of a pot-shaped housing that is open towards a cleaning surface, in which housing at least one rotor aim having spray nozzles attached to it is driven to rotate under the action of a high-pressure medium, wherein a manually operated valve device is present, which supplies the high-pressure medium selectively to one or more rotor arms and/or to the suction device, characterized in that, for two-handed operation, the manually operated valve device consists of two spatially separated operating handles with manually operated operating levers, which are arranged at the two ends of the push bar of the surface cleaner. 
     
     
         2 . The surface cleaner according to  claim 1 , wherein, in a first operating state with the actuation of the first operating lever in the first operating handle, the high-pressure medium can be supplied to the rotor aim, wherein, in a second operating state with the actuation of the second operating lever in the second operating handle, the suction device is supplied with the high-pressure medium alone, and wherein, in a third operating state with the actuation of both operating levers in the two operating handles, the high-pressure medium can be supplied to both the rotor arm and the suction device. 
     
     
         3 . The surface cleaner according to  claim 1 , wherein the high-pressure medium is applied via a high-pressure connection to the input of the first operating handle, to which a T-shaped adapter attaches, via which the high-pressure medium is directed into a connecting hose which opens into the input side of the second operating handle. 
     
     
         4 . The surface cleaner according to  claim 1 , wherein the push bar consists of two parallel push bar tubes which open into two parallel swivel joints in the region of the housing of the surface cleaner. 
     
     
         5 . The surface cleaner according to  claim 1 , wherein the upper, operator-end of the push bar opens into two oppositely positioned fork tubes, to which the operating handles are attached. 
     
     
         6 . The surface cleaner according to  claim 1 , wherein the actuating handles are designed as pistol grips. 
     
     
         7 . The surface cleaner according to  claim 1 , wherein the Venturi nozzle arranged in the suction device is preceded on the inlet side by a pressure relief valve. 
     
     
         8 . The surface cleaner according to  claim 7 , wherein the pressure relief valve, in the event of overpressure, directs the high-pressure medium at least partially into a bypass line bridging the Venturi nozzle and opening into the outlet of the suction device. 
     
     
         9 . The surface cleaner according to  claim 1 , wherein in the double operation mode with both surface cleaning and suction, the water consumption of the suction device is about 20% to 40%, preferably 33%, of the total amount of water. 
     
     
         10 . The surface cleaner according to  claim 1 , wherein the swivel angle of the push bar is continuously adjustable.
