Further down, a question was never answered from 2016! The unit has a socket for connecting additional devices. The question was asked what kind of socket it is, i.e. whether it is Swiss standard or also European and therefore useless if you need another adapter for it (at least unsightly). Does it need it there and would the second adapter also be included, was the question from 2016! I also noticed that they mix things up easily. For example, you can click on the Swiss version. But this is not the Swiss version, but a different model and with different accessories. For example, it does not have the suffix "P" (Extension Kit!) and even with "P" it would not have an additional hose or hose extension.
