Kohl's offers the iRobot Roomba 620 Vacuum Cleaning Robot for $359.99. Coupon codes "BIGSAVER" and "HOME10" cut that to $297.49. Plus, you'll bag $50 in Kohl's Cash. (The credit can be redeemed online or in-store from July 21 to July 31.) Assuming you'll use the credit and with free shipping, that's the lowest total price we could find by $27, although we saw it for $19 less a month ago. It features a self-charging home base, side brush, bristle brush, beater brush, brush cleaning tool, and iAdapt sensors. Deal ends July 20.
