Surface cleaning machine having double glide apparatus

Abstract

A surface cleaning machine includes a cleaning head having a double glide apparatus formed by a first glide member in front position and a second glide member in rear position. The first and the second glide members are joined together along a portion of their facing walls, a longitudinal cavity being defined therebetween that opens to the surface to be cleaned. Each of the first and the second glide members has one or more suction openings defined in its bottom wall, and the second glide member also has one or more inlet openings defined in its rear wall to receive a cleaning solution, which is delivered through the cavity to a surface to be cleaned and is removed from the surface by action of vacuum applied through the suction openings.

         7 . A double glide apparatus for a surface cleaning machine, the double glide apparatus comprising:
 a first glide member having,
 a first inner and a first outer longitudinal wall, and a first bottom wall, and 
 a first suction opening defined in the first bottom wall; 
   a second glide member having,
 a second inner and a second outer longitudinal wall, and a second bottom wall, and 
 a second suction opening defined in the second bottom wall, and 
 a plurality of inlet openings defined in the second outer longitudinal wall to receive a cleaning solution, 
 wherein the first and the second glide members are fixedly coupled to one another along the first and the second inner longitudinal walls, and 
 wherein a cavity is defined between the first and the second inner longitudinal walls, the cavity receiving the cleaning solution from the inlet openings and delivering the cleaning solution to a surface to be cleaned; 
   a plurality of Venturi tubes fluidly coupling the inlet openings to the cavity, each of the Venturi tubes delivering the cleaning solution from one of the inlet openings to a nozzle on a wall of the cavity; and   a plurality of nozzles nozzle each ejecting the cleaning solution from one of the Venturi tube into the cavity, the nozzle projecting the cleaning solution in a direction perpendicular to the surface to be cleaned.   
     
     
         8 . The double glide apparatus according to  claim 7 , wherein walls of the first and the second suction openings have walls with ridges defined thereon. 
     
     
         9 . The double glide apparatus according to  claim 7 , wherein the first and the second suction openings each comprise a plurality of suction openings longitudinally communicating with one another to form the first and the second suction openings, each of the suction openings being in fluid communication with a plurality of first and second suction vanes defined in the first and the second glide members. 
     
     
         10 . A surface cleaning machine comprising:
 a cleaning head having a double glide apparatus that comprises:
 a first glide member having,
 a first inner and a first outer longitudinal wall, and a first bottom wall, and 
 one or more first suction openings defined in the first bottom wall; and
