Automatic large surface cleaning machine

Abstract

The apparatus consists of liquid/gas reservoirs and a movable reciprocating outlet nozzle connected to a pressure pump and connected to a vacuum unit, all of which are mounted on a small movable machine and all of which are driven by one engine of the small movable machine. The pressure pump is connected in some fashion to the drive shaft of the engine such that the power of the surface cleaning system automatically adjusts depending on machine speed. Also the nozzle systems sucks dirty liquid or dirt collected from the liquid/gas through a filter into a trash receptacle and moves the clean liquid into the mounted reservoir for use again by the pressure pump.

What is claimed is: 
     
         1 . An automatic surface cleaning machine comprising a small self-propelled machine; pump or compressor; manifolds with nozzles; a liquid/gas tank; movable nozzle systems; suction systems, and, liquid/gas transportation systems wherein the pump/compressor is attached to the engine of a small maneuverable machine such that the liquid/gas power system and speed of the delivery system are dependent on the speed of the self-propelled machine. 
     
     
         2 . An automatic surface cleaning machine according to  claim 1 , which has one or more movable nozzle systems supplied with liquid/gas through flexible pipes which move in opposing parallel directions in a sawing motion. 
     
     
         3 . An automatic surface cleaning machine according to  claim 2  wherein the flexible pipes are made from spring steel and simultaneously function as springs to return the manifolds to their initial position. 
     
     
         4 . An automatic surface cleaning machine according to  claim 1  wherein the nozzles are installed in an impeller. 
     
     
         5 . An automatic surface cleaning machine according to  claim 4  wherein the nozzles are installed in an impeller, which impeller simultaneously has a suction function. 
     
     
         6 . An automatic surface cleaning machine according to  claim 4  wherein the nozzles are installed in the impeller vanes with different radii from the center of the impeller. 
     
     
         7 . An automatic surface cleaning machine according to  claim 6  wherein the nozzles are installed in the impeller vanes top surface according to the cross evolventa with the vanes.
