    Advantageously, the coupling portion 23 and the internal sun gear 24 are in one piece, and the speed reducer 21 comprises a frame 28 fixed on the internal support wall 22 and on which the external sun gear 25 is formed. The external sun gear 25 can by example be formed by an internally toothed crown. The frame 28 may optionally include a fixing finger 29 extending through a passage orifice provided on the internal support wall 22. Advantageously, the fixing finger 29 extends parallel to the longitudinal axis A of the rotary brush 13 and is offset from the longitudinal axis A. The frame 28 is also advantageously fixed to the internal support wall 22 using fixing screws.
    An elastic ring 32, also called a circlip, is advantageously provided on the internal sun gear 24 in order to maintain the speed reducer 21 assembled during the removal of the rotary brush 13. The elastic ring 32 prevents, or at least limits, a translation of the internal planetary 24 with respect to external planetary 25
    According to the embodiment shown in the figures, the rotary brush 13 also includes a bearing 33, such as a rolling bearing and in particular a ball bearing, interposed between the fixing part 17 and a support ring 34 located inside the brush body 14 and fixed to an end portion of the brush body 14 which is situated opposite the drive motor 19. The presence of the bearing 33 makes it possible not to drive the part in rotation fixing 17 when the brush body 14 is rotated by the drive motor 19. Advantageously, a damping element 35 is interposed between the fixing part 17 and the bearing 33. For this purpose, the part fixing 17 may include a receiving housing in which is mounted the damping element 35, the bearing 33 being disposed between an internal surface of the damping element 35 and a central portion of the support ring 34.
    Advantageously, the cleaning head 2 is devoid of any bearing capable of cooperating with the second end 14.2 of the brush body 14 which is located on the side of the drive motor 19.
    Of course, the present invention is in no way limited to the embodiment described and illustrated which has been given only by way of example. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
