Save $270: Robot vacuums are one of the most competitive categories during Prime Day, but few deals stand out as much as this one from iRobot. Amazon has dropped the Roomba 105X Combo with auto empty dock to to just $200 from its usual $470 price. That's the lowest price we've ever seen, and marks a steep $270 discount. Self-emptying robots with Lidar navigation tend to typically cost much more making this deal stand out.
