Proper Ventilation/Drying of Interior Plaster / Drying Time

I am currently having very good experiences with window vacuums for windows and water-bead spots on walls (plaster).

What kind of device is that?

What kind of thing is this?

I could imagine something like a Kärcher window vacuum cleaner is meant.

well, if has had such good experiences, I wanted to know exactly that ...

Good question. But actually, I could imagine that it works. We have such a thing and even though the catch container is very small, it does go down from the window quite well.

But do I need something like that even if I'm not currently building a house?

It's actually for window cleaning. You have a squeegee-like attachment, a spray nozzle for glass cleaner, and the vacuum. Makes window cleaning very simple and effective.
