This item was used twice by the original owner and it worked great, but her elderly cat freaked out and kept trying to attack it.  The Roomba survived (so did the cat) and went back in its box, because, as we all know, eccentric old cats are more important than clean floors.  But somebody should have clean floors, so why not you?
