A new CNET article notes that the iRobot Roomba is a hot item among Christmas shoppers this season. Best Buy claims it's the most popular gift item at their stores this year and the Roomba 4100 has also recently reached the number four position on Amazon's Housewares top sellers list (it has since dropped to position six). The San Mateo Daily Journal recently picked the Roomba as number six on its list of the top ten holiday gadgets. So you better watch out, Santa may be bringing you an autonomous robot vacuum cleaner this year.
