• a motor is arranged inside the roller 15 and to provide the controlled rotation of the roller 15.
• the motor can be electric. It can also be hydraulic, the pressure of the cleaning liquid circuit providing the energy for the rotation of the roller.
• the energy supply can be provided by a mobile unit described later.
• the roller 15 comprises an outer layer formed by a cleaning fabric 20, this fabric 20 being ideally made of a microfiber material having a high absorbency.

• the outer layer can comprise several turns of strip of fabric, the junction between each turn following a helical shape around the longitudinal axis which avoids forming a fabric junction along the longitudinal axis and thus limits possible tearing of the fabric.
• the chassis 14 carries means for supplying a cleaning liquid.
• Said supply means are supported by a support 22 fixed to the central part 16 of the chassis 14.
• the support 22 comprises two arms 22a, 22b substantially parallel to each other and connected at their opposite ends to the central part 16 of the chassis 14 by a plate 22c. itself supporting a plurality of nozzles 24 for spraying a cleaning liquid.
• Each nozzle 24 is capable of spraying cleaning liquid along a cone 26. It is understood that other means than nozzles 24 could be used, for example means for spraying cleaning liquid along a line. It would also be possible to supply liquid to the fabric via its radially internal face by means of flexible conduits which could be carried by the side plates L1, L2.
• the nozzles 26 are supplied with cleaning liquid via a common connector 28 connected to a cleaning liquid supply conduit coming from a mobile unit 30 which will be described later with reference to FIG. 10.
• the nozzles 26 for spraying cleaning liquid make it possible to bring liquid onto a longitudinal zone 32 of the fabric 20, which zone 32, once impregnated with cleaning liquid, will come into contact with a glass surface 18 (see figures 3 and 4).
• the nozzles 26 are substantially aligned longitudinally. As shown in FIG. 3, the nozzles 26 may have a central axis 24a for spraying cleaning liquid that intercepts the longitudinal axis L of the roller 15. The axes 24a of the nozzles 24 are then coplanar. It is observed that the nozzles 24 spray cleaning liquid upstream and downstream and over the entire portion of the roller 15 arranged opposite the nozzle 24. This configuration is not optimal since it leads to spraying liquid below the roller 15 and can lead to excess consumption of cleaning liquid.
• FIG. 4 illustrates a variant in which the spray nozzles 24 are shaped so that the axis 24b of each nozzle 24 has a central axis that does not intercept the longitudinal axis of the roller. It is observed that the central projection axis 24b has been offset so as to project more cleaning liquid in front of the roller 15.
• the cleaning device 10 also comprises wringing means and means for collecting waste water.
• the wringing means make it possible to continuously wring the fabric 20 of the roller 15 so as to prevent it from becoming saturated with water and also so as to continuously recover the dirt.
• the wringing means comprise a scraper 34 which is here a substantially rectangular plate and which is carried by the frame 14.
• This scraper 34 comprises a longitudinal edge 34a for scraping the fabric 20 of the roller 15.
• This longitudinal edge 34a is arranged in contact with the fabric 20 of the roller 15 and more specifically so as to penetrate the fabric 20 in order to compress it and therefore extract the waste water therefrom.
• the used liquid is recovered by the collection means and more particularly by a bowl.
• These collection means comprise a concave curved wall 36 arranged in the immediate vicinity of the fabric 20 and which is connected to a collection wall 38 so as to form a leading edge 40, that is to say a projecting edge facing the wringing means 34 so as to promote the orientation of the waste water towards the collection wall 38.
• the concave curved wall 36 here has a profile with a constant radius of curvature centered on the axis of rotation. This profile could also not be constant.
• the leading edge 40 has a substantially rectilinear shape and parallel to the longitudinal axis L.
• the collection wall 38 has at least one trailing edge 42 comprising at least one portion 42a extending from a longitudinal end of the collection wall 38 to a discharge orifice 44 for the waste water from the bowl. It can be seen that the trailing edge 42 comprises two portions 42a converging towards each other from opposite longitudinal ends, and up to a plane perpendicular to the longitudinal axis L passing through the waste water discharge orifice 44 (FIG. 9).
• the trailing edge 42 of the collection wall is connected to a blocking wall 45 which thus forms, with the collection wall 38, the waste water recovery bowl.
• the discharge orifice 44 is formed at the end of a connector 46 connected to the distal end of a discharge conduit itself connected to the mobile unit 30. It can be seen that the collection wall is also curved.

• connection 48 for supplying cleaning liquid to the device 10 connected to a tank 50 of cleaning liquid, this connection 48 is connected to the connection 28 of the nozzles 24 of the device 10 by a flexible conduit (not shown),
• this connection 52 is connected to the discharge connection 46 of the device 10 by another flexible conduit (not shown).
• the mobile unit 30 also comprises means 56 for supplying energy to a pump 58 for supplying the cleaning liquid and to a pump 60 for discharging waste water.
• the cleaning liquid spraying means spray cleaning liquid onto a given or predetermined longitudinal area of the fabric. Due to the rotation of the roller 15 in the direction R, this area comes into contact with the glass surface 18 at t+t1 and by rotation of the roller 15 makes it possible to clean the glass 18. At a later time t+t2, said area 32 then comes into contact with the scraper and the waste water flows into the bowl of the collection means.
• the discharge port allows the water to be discharged through the discharge pipe to the waste water tank 54 of the mobile unit 30.
• the invention thus makes it possible to simply and quickly clean a glass surface by limiting the quantity of water required and without requiring a physical connection to a water circuit.
• the specific arrangement of the collection means relative to the scraper and the water spraying means makes it possible to carry out impregnation, scraping and water collection on each tower, which allows optimal cleaning of the glass surface.

• the hooding means may comprise a concave curved wall 68 with a concavity oriented towards the roller and one end of which is connected to the longitudinal blocking wall 66 and at a second end to the collection means, more precisely to the bowl.
• This concave curved wall may be longitudinal, i.e. extend along the longitudinal axis of the roller 15.
• a first end around the longitudinal axis may be connected to a longitudinal end or edge 66b of the longitudinal locking wall 66 which is opposite the longitudinal end or edge arranged opposite the roller 15.
• a second end around the longitudinal axis L may form a part of the bowl as can be seen in FIG. 13A. In this way, the cleaning liquid projections are contained inside the cover means.
• the longitudinal zone 32 is housed inside the enclosure and formed between the end of the blocking wall facing the fabric 20 and at a distance from it, and the wringing means 34.
• the curved wall 68 carries on its concave curved face the wiping means, more particularly the scraper, which are therefore housed in the enclosure.
