This means, as a rule, a German plug. In addition, a transition plug is supplied that connects firmly to the existing plug. Works without problems. Caution is only advised with those vacuum cleaner models that have an internal socket for connecting another device (e.g. saw, grinder, etc.). In this case, the CH plug does not fit either and would also require a transition plug.
With this product, it is only the plug. If you don't mind having a Schuko plug with a CH adapter, you can order the EU version.
Country version
Describes the version of the unit. CH versions usually come with Swiss power plugs and Swiss warranty. EU versions are supplied with power adapters for CH sockets and an EU warranty.
Good evening, I have a nice older Kärcher dry/wet vacuum cleaner and have not used a bag for a long time. It works perfectly. Of course, you have to clean the air filter more often (best to blow it out with the air gun). LG Markos
