Can anyone tell me what model #4130 is? I can't find it anywhere else, even at Roomba's home page. Is this a reconditioned model? The picture at buy.com looks like model #4230 (schedular) but I really would like to know if it is or not... If anyone has any information on this, could you please post it here? Thanks. By the way, is it just me, or is it kind of strange to have all 4 reviews written on the exact same day?
