I've had that happen once. I kept finding puddles all over the floor and couldn't figure out why. Then saw her drinking from the bar and a few seconds later a big puddle. I had to remove the bar to keep her from it. She was still lazy about cleaning, so I replaced her. Her replacement didn't seem to want to clean either. She would get a book out and read it, go into a room check herself out in the mirror and wander around, like she was lost. Go back to reading a book again.
I got rid of her and three times the charm she has been a good boney maid.
Sometimes you have to just go through several maids until you find one that works out for your family. I have one that is great in everything, except the baby/toddlers. She won't leave them alone, she will give a bottle, change a diaper and play wih them, but won't let them sleep at all.
I dismissed her, she went into her coffin stayed there for a few mintues and then came right back out heading straight to the baby. I ended up waiting until she shut the door, paused it and then built a small room just big enough for her coffin as far away from the house as I could. Stuck her in it, she couldn't get out so just stayed in it. Returned her to the house after the last toddler aged up to child.
They all seem to have different quirks about them.
Just keep trying until you find one you like is my suggestion.
