My sims can’t vacuum

bmoresvolcano​ Ok, I dled the lot and took a look at it.  I found the issue preventing you from vacuuming on that floor and a fix. The reason your sim can't vacuum on the 2nd level is that the game is not seeing the room with the pink carpet and the attached bathroom as rooms.  It is seeing both the bedroom and bathroom as being outside, rather than a legitimate rooms.  When I click on the floor, the entire floor gets selected, so the game is seeing that entire floor as one outside space.

So, to fix it, you'll need to redraw the walls for the bedroom and bathroom.  Since you've used round walls, you can't use any of the wall tools to simply draw over the existing walls.  You'll need to use 2 round wall sections and then adjust them at the corners, delete the wall you get between the 2 sections and redraw the bathroom walls to get the same layout.  Of course, redrawing walls always wipes out the wall paint and a lot of the wall hung objects so you will have to redo all of that.  You'll probably have to put the furniture back and possibly the stairs.  But you can get it back to your original layout and look with a bit of work.

Hope this helps.
