  • a cover wall 90 is provided, in which the passage openings 88, however, are surrounded by frame-shaped enclosure, which form-fit the frames 78 of the contact element carrier 76.
  • the frames 78 at the loading station 102 are oriented at an angle with respect to the wall 66 which results from a right angle and the inclination of the ramp 110 with respect to the horizontal. This is advantageous because the contact portions 92 of the contact elements 62 also define a plane in the cleaning system 100 which is aligned perpendicular to the contact plane of the floor cleaning device 12 arranged on the ramp-up area 106.
  • the Cleaning system 100 is also guaranteed. Even with the cleaning system 100, the contact elements 54, 62 can be coupled to one another in a simple manner, although they are arranged with respect to the outer contour of the housing 16 or the end face 86 of the frame 78 set back on the floor cleaning device 12 and the charging station 102.
