Kohl's offers the iRobot Roomba 620 Robot Vacuum for $349.99. Stackable coupon codes "HOME15" and "YES20" cut the price to $267.99. Plus, you'll receive $50 in Kohl's Cash. (It can be spent online or in store from February 5 to 14.) With free shipping, and assuming you'll use the credit, that's $54 below our mention from two weeks ago and the lowest total price we've seen. (It's a current low by $90.) It features a self-charging home base, side brush, bristle brush, beater brush, brush cleaning tool, and iAdapt sensors. Deal ends February 4.
