• a plastic material is ABS (acrylonitrile-butadiene-styrene copolymers) as an example of a thermoplastic terpolymer.
• the ice removal tool 62 can be exchanged in a simple manner.
• a labyrinth seal can be formed in a simple manner in order to prevent the penetration of fluids into the housing 12.
• a simple coding results, so that only correct ice removal tools 62 can be used with the ice removal machine 10.
• other adapted tools can also be used, for example for cleaning vehicle windows.
