Scared to invest and build another simbot? But it's so easy...
Either way, the sims are still being surprised by a simbot every second they spend near one, cancelling the whole queue (like that 8-action queue you make for your sim while he/she sleeps) and stop doing whatever they're doing* to react to a SimBot, even if they have already seen the same SimBot at least a thousand times and live with it.
*Picture this little thing that happened to Steven Brustle (my signature's sim) when he had a SimBot:
-So I'm gonna take out the trash, lalala...
*Stops walking*
*Drops loaded trashbag in the middle of the living room for no apparent reason*
*Forgets what he was about to do next*
*Looks at Robbie Brustle, the SimBot that he built, who has also been his best friend and roommate for over 2 generations*
-OH MY GOD! A SIMBOT!
*Gets frightened as if he saw a mummy, and panics upon thinking what technology is capable of doing and if it will take over the world*
