My house has three floors. The first and second floor is no problem, the Sims are able to vacuum and the dust disapears.
But on the third floor the Sims cannot vacuum. They try once but fail. And then the option for vacuuming is gone and instead there is the option to empty the vacuum cleaner. But no matter how many times my Sims empty this thing, the vacuume option doesn't come back.
The upstairs is fully enclosed with walls and ceiling. You can see the difference by the lights, because the lights would be different if there was a hole somewhere hidden.
The only solution I found is to build another tiny room inside this room, teleport the Sim inside and let him do the vacuum job. After that the floor is clean.
This may be a temporary solution, bus it is not ideal because first you always have to have the room and the money to build another room and when deleting it you have to delete it one by one wall to make sure you're not deleting anything importand in that room.
I really hope that this will get fixed soon! Even with mods this happens...
