Also at the same time as you're doing something else. I often run the roomba as I clean other stuff or do the dishes when I prepare for a visitor. If you run it daily or every other day, the first couple of days it's full of dust and hair, then less and less. I view this as evidence that it's needed. I don't dare keep it on a schedule nowadays, because I have kids who leave stuff on the floor everywhere, including charging cables for phones that can get tangled up in the roomba. What I usually do is a quick check under the couch and tv bench, then start it manually when I leave for work.
