Did you know there is a new Roomba model? Neither did we, but we read over at Popgadget that it's now available on Amazon. Which begs the obvious question, what is new about the Roomba 560? iRobot touts that it has improved cleaning performance and navigation. We looked at the product comparison and deduced that the 560 has become middle price-point between the 530 and 570 models. At $350, the Roomba 560 is the 530 model with some of the features added from the higher end machine, including Lighthouse guidance technology and on-board scheduling.
