Reiner Sauberhasi appeared in Sesamstrasse episode 2350.

He tried to sell a vacuum cleaner, the Saugi2000, to Rumpel, but did not have any luck with that. But then he came to Nils' store and lucky for Reiner, Nils vacuum cleaner broke down and he made a sale. He then got the idea of selling Nils' used vacuum cleaner to Rumpel, and that also turned out to be a successful sale. He ended up concluding that it has been his lucky day.

The puppet was recycled from Sesame Street's Preston Rabbit.
