We have a Roomba, though I think it's back in its box in a cupboard now. In the end it needed so much babysitting that I gave up and bought a cordless stick vacuum. That is the best home appliance purchase I've ever made. The lower hassle of not needing to extend and roll up the cord compared with my older vaccuum massively outweighs any benefit from the Roomba. Grabbing the stick, quickly buzzing it around for a couple of minutes and putting it away again is far less hassle than babysitting the Roomba.
