As one of its daily deals, offers the factory-refurbished iRobot Roomba 560 Robotic Vacuum Cleaner, model no. 56099, for $175 plus $5 for shipping. That's the lowest total price we could find by $60 for a refurb, although we saw one for $10 less two weeks ago. The Roomba 560 includes a charger, two virtual walls, and brush cleaning tool. It features dirt sensors and on-board scheduling, which provides up to seven automated cleaning times per week. A 90-day iRobot warranty applies.
