I do not own one but have considered. Those that I know that have one AND that have pets ALL have horror stories of the thing encountering poo on the carpet. Picture this, a robot dragging around soft poo on your carpet accompanied by a rotating brush that swirls and pushes into your carpet all while covering every square inch of your floor. Then there is the cleaning of poo out of the roomba. Those I know that have experienced this all said the same thing. They would rather just vacuum/sweep on their own not to have to clean this mess again.
