A portable machine for steam cleaning carpets, rugs, automotive engines and soiled areas including an electrolytic generator for substantially instant production of steam, a positive displacement pump for delivering a water-chemical solution from a tank to the electrolytic generator and from the electrolytic generator a discharge of steam via a flexible hose and nozzle onto a soiled area including automotive engines. When adapted primarily for rug and carpet cleaning the machine includes an air pump and solenoid for delivering detergent from a tank to the nozzle and a vacuum motor with nozzle for picking up excess moisture and dirt particles released by the steam solution.

A portable steam cleaning machine comprising, in combination, a casing, a plurality of casters attached to said casing for ready movement thereof, an electrolytic generator for generating steam consisting of a pair of spaced carbon rods, a sealed receptacle mounted within said casing for containing said carbon rods, a positive displacement pump mounted within said casing adjacent to said receptacle, a tank mounted within said casing for holding a liquid solution consisting mainly of water and a small amount of ammonium nitrate, tubular means for connecting said positive displacement pump to said tank and to one side of said receptacle, tubular nozzle means having one end connected to another side of said receptacle, and electrical means for energizing said carbon rods and said positive displacement pump, whereby liquid from said tank is fed by said positive displacement pump into said receptacle to contact both of said carbon rods and close an electrical circuit for said electrolytic generator for producing substantially instant steam to be discharged from said nozzle means upon a surface to be cleaned. A portable steam cleaning machine in accordance with claim 11, including a tank containing a detergent solution mounted within the casing, an air pump mounted within said casing, a solenoid valve mounted within said casing adjacent to said air pump, tubular means interconnecting said air pump and said detergent tank, tubular means interconnecting said detergent tank and one side of said solenoid valve, tubular means interconnecting another side of said solenoid valve and said nozzle means, and a second electrical means for energizing said air pump and said solenoid valve, whereby atmospheric air is pumped into said detergent tank by said air pump to force detergent solution from said detergent tank through said energized solenoid valve and discharged from said nozzle means in conjunction with said steam discharge. A portable steam cleaning machine in accordance with claim 12, including a vacuum motor mounted within said casing, a suction tank mounted within said casing contiguous to said vacuum motor, a hose having one end disposed within said suction tank and having its other end included as part of said nozzle means, and a third electrical means for energizing said vacuum motor, whereby suction produced by said vacuum motor renders the nozzle means effective to pick up soil loosened by said steam and detergent from a surface of a carpet being cleaned and deposited into said suction tank by said hose.
