Roomba 4230 Scheduler Robotic Cleaner

This particular Roomba is a scheduler and you can schedule 7 different times that Roomba will come out of his base and start to vacuum. My sister just loves this Roomba. It picks up the dog hair and finds the littlest crumbs. She purchased two additional Virutal Wall Schedules and very happy she did. I laughed the first time I saw Roomba in action. Truly Amazing!
