- the layer 59 is applied by printing the housing part 30 from the underside.
- the actuating element 58 is printed annularly along the entire circumference on a light-absorbing region 60 which absorbs at least part of the visible spectrum. This allows inking on the actuator 58 from the underside ( Figures 4, 4A).
- an identification 61 on the actuating element 58 is ensured via the light-absorbing area 60 .
- pictograms are printed on the actuating element 58, which will be discussed below.

- the display unit 37 is connected to the housing part 30, in particular to the cover element 57. In the present case, the connection is made by gluing.
- Figures 7 to 10 show the corresponding adhesive layer 66, for example by OCA bonding.
- the bonding is carried out in such a way that the plane of the display unit 37 is aligned parallel to the plane of the housing part 30 .
- an optical coupling of the display unit 37 to the cover element 57 takes place via the adhesive bond. Light reflections between the cover element 57 and the display unit 37 can thereby be avoided.
- the housing part 30 rests against housing side wall parts 29 via a damping element 67 .
- the damping element 67 is made of an elastically deformable material, in this case for example an EPDM foam material. Reference is made to the statements above in this regard.
- the damping element 67 is ring-shaped and extends along the entire outer circumference of the housing 26.
- the actuating element 58 rests along the outer circumference on the damping element 67 which in turn rests on an upper section 69 of the housing side wall part 29 .
- Adhesive bonding of the damping element 67 to the housing side wall part 29 and to the layer 59 on the actuating element 58 is preferably provided.
- the damping element 67 can be elastically deformed by pressure on the actuating element 58 . Conversely, reshaping can take place in order to move the actuating element 58 back into an initial position. For this reason, the damping element 67 also forms a restoring element.
- the damping element 67 seals between the housing part 30 (including the layer 59) and the housing side wall part 29.

- the respective switching element 36 In a basic position ( Figures 7, 9, 11 and 13), the respective switching element 36 is not actuated.
- the actuating area 70 By pressing on the actuating area 70 in an arrow direction 71 ( Figures 8, 10, 12 and 14), the actuating area 70 acts on the actuating element 48 on the respective projection 52.
- the actuating element 48 pivots on the film hinge 50 until the free end 51 actuates the switching element 36.
- the electrical unit 32 can provide information about forward the actuation to the electrical device 15 of the cleaning device 12, 22, 23 or 24.

- the damping element 67 is used to form a defined compressive force and to generate haptic feedback for the operator.
- the actuating element 58 is tilted on the housing 26 (FIGS. 8, 10, 12, 14).
- the actuating device 20 is dimensioned in such a way that a relatively small tilting path of approximately 0.3 mm to 2.5 mm, preferably approximately 0.5 mm to 2 mm, is set.
- the display unit 37 also moves the display unit 37. Specifically, the display unit 37 is moved in the same direction as the cover member 57 and in synchronism with it. The optical coupling, in particular through the connection via the adhesive layer 66, is retained. Visual information on the display unit 37 can be independent of the tilted position of the actuating element
- a structurally identical actuating device 20 is used in each case. Only a program stored in the memory unit 17 is different. The program is used to control the respective cleaning device 12, 22, 23 or 24, and its functions can be addressed. Furthermore, the visual information on the display unit 37 will vary depending on the program provided for the respective type of cleaning device 12, 22, 23 or 24.

Subsequent to an optional greeting 79, the user can select submenus 80 within the main menu level 77 by actuating the actuating areas 70c and 70d. Entry into a respective menu level 81 of the selected submenu takes place by actuating the actuating area 70b.
- the operator can navigate within each menu level 81 by actuating the actuating areas 70c and 70d.
- a respective option 82 in a submenu 80 can be confirmed after selection by actuating the actuating area 70b, whereupon the main menu level 77 is called up again.
- the device 15 can, for example, be switched off at any time by actuating the actuating area 70a.
- the actuation area 70a is the actuation area 70 furthest away from the grip element 18 . Unintentional switching on or off can thus be largely avoided. With regard to access to the menus, it is advantageous if the actuation area 70b is arranged closer to the grip element 18 than the actuation area 70a and/or the actuation area 70 is arranged closest to the grip element 18 .
