Kohl's offers the iRobot Roomba 620 Vacuum Cleaning Robot for $359.99. Coupon code "SEPT20" cuts that to $287.99. Plus, you'll bag $55 in Kohl's Cash. (It's redeemable online or in-store from September 6 to September 14.) With free shipping and assuming you'll use the gift card, that's the lowest total price we could find by $62, although we saw it for $2 less in July (respective of its gift card). It features a self-charging home base, side brush, bristle brush, beater brush, brush cleaning tool, and iAdapt sensors. Deal ends September 5.
