iRobot's Roomba Combo j7 is $305 off for Black Friday

Sometimes Black Friday is about picking up a fun new gadget and other times it's about getting a really good deal on that practical item you need. The majorly discounted iRobot's Roomba Combo j7 falls deeply into that latter category, but the $305 savings is enough to get anyone excited. You can access the deal at Wellbots with Engadget's exclusive coupon ENGBF305 -- and get free shipping. The iRobot Roomba Combo j7 is a 2-in-1 vacuum and mop for cleaning all types of floors. It can do both tasks in the same go (without you needing to interfere) due to its retractable mop pad.
