Hey Crin!
So when the house is clean, it gives a +2 inspired moodlet. I don't have any focused decor that I can see, and what I found online mentioned items that were given as rewards when 4 came out to those who had certain expansions of sims 3 registered on origin (the plumbom lanterns more specifically). I had all sims 3 expansions, but they are hard disks so I didn't get those.
I did find out that if you let the house get dusty (like stage 1 dust where you see the first dust bunny), it changes to a +1 happiness moodlet, and the focus one can override that.
While I'm glad I was able to find a workaround, the fact remains that I shouldn't HAVE to.
On a side note, I wanted to mention that I also discovered last night that if a sim has a vaccuum in their inventory, they will stop doing anything you ask them to do (like bathe, workout, etc) and constantly keep cleaning the floors even after they are clean. So you have to clean the floor, then remove it out of their inventory. Another thing I found is that the little roomba-like machines won't work on upstairs rooms. My sim is in one of the original upper class houses and it just stalls no matter where I place it. Even on my other file where the sim is in a single level home, it will work and then just give a little "can't move" explanation symbol and then just sit there and do nothing even if you tell it to go back to its dock. You have to go into build mode and manually move it back.
The kit overall is just very wonky.
