Question about Electrolux Chill Flex Pro

This only works if you have prepared such a great window kit in each room and then connect the hose to it. The comment 'can be easily changed from room to room' is very exaggerated. It's not that simple. It's always the same with the pictures, you hide all the ugly things like hoses. If you look at the last picture, you can see part of the Premium window kit by the window door. But the hose is nicely hidden behind the unit and not visible.
