DETAILED DESCRIPTION

[0033] Preferably, all identical components, elements, and/or units are provided with the same reference symbols in all figures.

[0034] FIG. 1 shows a cleaning arm 10. The cleaning arm 10 comprises a bottom element 12. Furthermore, the cleaning arm 10 has a side element 14, which is formed in one piece with the bottom element 12. As can be seen in FIG. 1, the side element 14 is preferably disposed orthogonally to the bottom element 12. The cleaning arm 10 also preferably comprises a bushing 16. The bushing 16 is used to attach the cleaning arm 10 to a cleaning rotary motor 202 of the cleaning system 200. Furthermore, the cleaning arm 10 comprises a pin 34, which can secure a hose 22 in the cleaning arm 10. Furthermore, the cleaning arm 10 comprises an opening 28 which can be used to guide the hose 22 from the outer side 30 of the cleaning arm 10 to an inner side 32 of the cleaning arm 10. The cleaning arm 10 also comprises a web 18. The web 18 comprises a hole 11 in which a stud 20 can be disposed. A spring 26 can be disposed on the cleaning arm 10 by means of the stud 20.

[0035] FIG. 2 shows a cleaning arm 10, which has a second recess 24 on the web 18 for positioning a spring 26. The stud 20 is disposed on the web 18 in such a way that the spring 26 can be disposed on the stud 20. Further preferably, the cleaning arm 10 has a third recess 36. A pin 38 can be disposed in the third recess 36 to secure a windshield wiper 40 to the cleaning arm 10.

[0036] FIG. 3 shows an embodiment of the cleaning arm 10. The cleaning arm 10 has an outer side 30 and an inner side 32. The opening 28 of the cleaning arm 10 can be set up to guide the hose 22 from the outer side 30 to the inner side 32. The cleaning arm 10 also has a web 18 with a hole 11 in which the stud 20 can be disposed.

[0037] FIG. 4 shows the cleaning arm 10 according to one embodiment. The cleaning arm 10 has a web 18 with a hole 11 in which a stud 20 can be disposed. Furthermore, the cleaning arm 10 comprises a third recess 36 for securing a stud 38.

[0038] FIG. 5 shows the method 100 for manufacturing a cleaning arm 10 of a cleaning system 200 comprising the steps: [0039] of cold forming S1 of a blank with at least one hole 11 for forming: [0040] of a bottom element 12, [0041] of a side element 14, which is formed to be essentially orthogonal to the bottom element 12, [0042] of a bushing 16 for attaching the cleaning arm 10 to a cleaning rotary motor 202 of the cleaning system 200, [0043] of a web 18, wherein the hole 11 is disposed on the web 18, wherein the hole 11 is positioned such that a stud 20 can be positioned in the hole 11 to secure a spring 26 to the stud.

[0044] The method further comprises the step S2 of cutting out an opening 28 in the bottom element 12, wherein the opening 28 is arranged to guide the hose 22 from an outer side 30 of the cleaning arm 10 to an inner side 32 of the cleaning arm 10.

[0045] Furthermore, the method 100 comprises step S3 of bending the pin 34 so that the pin 34 secures the hose 22 to the side element 14.
