By short cuts, do you mean short circuited? Meaning she shorts out and stops working? SimBots are prone to this type of thing, especially if you put them in water. I had mine get in a hot tub and he shorted out.
As for the other issues, they don't have anything special. They sleep as much as a regular Sim. They live longer than a normal Sim, but I don't think anyone knows for sure how long. On top of that, all the other Sims get that interruption "Oh! A SimBot!" that is very annoying. I don't bother with SimBots anymore. You can always just kick it out of the house and it'll live on it's own.
