Willen: Can it work in multiple rooms of 200m2?"

We recommend not using more than 2 rooms of 150m2 for Willem to work in.

The reason for this is that Willem stores a map of the rooms he is in. So, if you save 2 rooms in the App and Willem, for example, goes to the next room on a different day, something in that room may have changed. This could be a door that is open or closed, or a shift of objects in the room, causing Willem to close off or split a room and thus not finish the room properly. This would be annoying for you if you expected that room to be completely done, but it wasn't due to the changes in the map.

It is therefore not very wise to use many different rooms for 1 Willem.
