I have the ROOMBA! Yes the robotic vacuum cleaner. I love it. My dad sent it to us for Christmas. The cats are not afraid of it at all and it can do under the sofas and the king sized bed without a problem. Although I do use a canister to get along the walls and in the smaller places but it has saved so much time and effort. I just clear the space of cat toys...turn it on and go do something else like read or watch TV...hehehe
