Will butlers do laundry?

I've honestly only had a couple of butlers and they were practically useless. They always either read a book in the weirdest part of the house or asleep. But I have heard that they are like TS3 butlers who you do have to hire and fire a couple before you get the right blend. And I had a fair few in TS3 with 5 kids but I did have to hire/fire a few to get the most perfect one in the end. Have tried this theory in TS4 yet but when I get back in playing I will.
