Keeping a clean house has topped a lot of people's priority lists these days. Luckily, Amazon is having a huge sale one of our favorite robot vacuums--the iRobot Roomba i6 --which is at its lowest price we've ever seen. This model is actually a variant of our favorite robot vacuum ever, the iRobot i7 ($799), and we love it because it's a set-it-and-forget-it kind of robot.
