  • each of the flexible conduits 85 which rubs on the ground is bevelled.
  • each of the flexible conduits will adapt by tilting more or less relative to the wall 84 to the reliefs of the ground helped in this by its beveled end.
  • This arrangement of the invention makes it possible to obtain the suction of the rinsing water without it being able to be retained by the hollows in the ground in the case of soils having a succession of hollows and reliefs as is the case fear certain floor coverings in synthetic materials likely to be defined by their configuration in honeycombs.
  • the shoe has electrical wiring for supply and control of its various organs.
  • control can be carried out either from the operating bar fitted with devices for controlling the brushes, the spraying of detergent liquid, the suction and the spraying of the rinsing fluid, or from the control panel. control of the vacuum cleaner as stated above with a connection cable to that of the shoe.
  • the shoe according to the invention is fixed to the front of the vacuum cleaner by any known means so that by pushing one, the user pushes the other.
  • the device according to the invention is however provided with separate controls for each of the above functions so that it is possible at first to spray detergent, to clean by brushes and to vacuum and secondly during a second pass, rinse with or without mechanical action of the brushes and suction of the rinse fluid.
  • FIG 14 is shown another embodiment of the suction shoe intended to be connected to the suction device as defined.
  • the chassis constituted by an assembly constituted by the assembly of longitudinal members and crosspieces covered by a cover is provided with a rear rolling member constituted by a roller 86 freely rotatable transversely to the chassis.
  • the brush rotates in bearings fixed to the chassis. Its axis is provided with a grooved pulley rotated by a belt 88 cooperating with the output shaft of an electric motor of known type 89 fixed to the chassis
  • a nozzle or a ramp of nozzles 92 for spraying a rinsing liquid supplied by a conduit as described above, either from the device for projecting the floor cleaning machine according to the invention , either by the water network of the room to be cleaned, or by a reserve of rinsing water, the duct being in this case next to a solenoid valve and a pump which can be fixed to the chassis between the ramp of projection nozzles and the source of rinse aid.
  • the shoe according to the invention is provided with two nozzles 93 and 94 transverse to the chassis joined to the suction duct 22 by forming a bypass 95.
  • the suction nozzle 93 comes in front of the cylindrical brush 87 and 18 ramp of spray nozzles 90 of the detergent liquid, the suction nozzle 94 .is placed at the rear of the cylindrical brush 87 and before the projection ramp 92 rinse aid. The lips of each of the tips are above the level of the floor to be cleaned.
  • an articulated valve 96 is actuated by a solenoid valve 97 connected to the valve by a rigid rod.
  • An axis transverse to the bypass and the ends of which feel fixed on either side of the shoe, for example in holes in the sides of the cover, makes it possible to tilt the assembly 93.94 e so that one or the other of the nozzle tips are in contact with the ground.
  • Failover can be achieved by any means.
  • cn uses an electromagnet 99 fixed to the chassis and connected to one of the suction nozzles by a rigid rod.
  • each of the end pieces is provided with a flexible accordion sleeve which allows by means of a screw, rack or chain system to raise one or the other of the nozzles above the ground.
  • Rinsing is carried out by pushing the shoe in the opposite direction, that is to say in reverse after raising the end piece 94, lowering semert of the nozzle 93, obturation by the valve of the nozzle 94 and projection of rinsing liquid, by the rail 92.
  • the rinsing liquid is, after the action of the brush, sucked up by the nozzle 93.
  • the shoe according to the invention is provided with electrical control means and control of its various organs.
  • the different members will be coordinated in operation so that the tilting of the suction nozzles causes, depending on the case, the interruption of the spraying of detergent or the spraying of rinsing liquid and the obturation by the valve of one or the other. other tip.
  • the user connects satisfactory lengths of water supply pipes, drainage pipes and suction and projection pipes chosen according to the respective location of the water point, connection to the drainage network wastewater and the area of soil it intends to clean.
  • the extraction pump will be started or stopped and the tank will empty in the drainage system worn without special monitoring or handling, which saves a lot of time.
  • the user interrupts the water supply, for example by closing the solenoid valve (s), as well as the operation of the hot water generator and the spray pump by electrical interruption.
  • the extraction and projection pumps are interchangeable.
  • the said bag inflates and stretches, scn bottom bends in a panty curved towards the orifice of the turbine casing, without however the walls of said bag pressing against that of the fan.
  • the air flow is directed tarentially to the cylindrical wall of the enclosure and following a turn.
  • Said air flow is intercepted by the conical wall of the bag and by the bottom curved in a cap so that it is. returned to the cover which by its conformation in a spherical cap plays a role of deflector of said air flow which performs inside the bag an elliptical swirling movement.
  • the vacuum cleaner according to the inversion can also receive a water tank shown in Figure 1 deté a central suction duct, said tank being fixed by the quick coupling system.
  • the machine according to the invention had the advantage of being versatile since it can be used as a machine for cleaning floors by wet or dry process and its suction shoe in its two embodiments makes it possible to produce a effective floor cleaning.
