Hello
I can't say anything about the IP protection. But the device itself is a closed system at the bottom. All the modules that can be attached are of course not protected. Sorry, that's all I can say. But the Multibrush is a great device and with the modules, it's quite unique, especially when it comes to surface cleaning. There is no comparison for me.
Greetings

I don't know whether the device belongs to a protection class, but it is not suitable for use in a wet environment.
The operating instructions say that it should be protected from moisture.

Does not work. Instructions for use say:
Do not immerse the appliance in water
or spray or clean it with water. The appliance must be protected from excessive moisture.

I don't think it works under water.
But ask Gloria customer service directly by email.
