every room has only a finite number of cool doodads at any given time. the room will be cleaned eventually, it just might take a little longer. not to mention that the extra time will be spent discussing cool doodads and will thus be time well spent.
That’s assuming you can only spend a finite amount of time on each cool doodad and can’t switch between them.
you bring up a good point that my original comment blindly assumed the cleaner would be a mortal. if they are immortal and thus able to spend an infinite amount of time on each doodad, then we might be in some real trouble here. depending on how interesting the doodads are, there’s a chance the room will be occupied forever. the only solution i can think of would be to lure the cleaner out with increasingly cooler doodads, but this may be easier said than done.
