For all of you current and potential Roomba hackers out there, you better watch out for strange behavior and read this FAQ on McSweeney’s:

How do children and pets react to Roomba?

In general, children and pets react positively to Roomba. In some rare cases, however, Roombas have been known to kill those they view as threats to their continued survival. If you notice your Roomba acting aggressively toward your pet or child, simply return the Roomba to your place of purchase for a full refund.

How can I tell if my Roomba is depressed?

Excessively long charging periods. Vacuuming the same spot over and over. Not moving.

I say, if all else fails, put some kittens on it.
