Finally, if you’re *really* looking to invest in a top-of-the-line Roomba, you won’t want to miss $400 off iRobot's most powerful model yet. It has a four-stage cleaning system that allows you to choose between vacuuming, mopping or combo both.

So many robot vacuums go on sale for Black Friday that decision fatigue is imminent — unless you're specifically set on a Roomba, that is.

The iRobot Roomba Combo i5+ is a self-emptying robot vacuum and mop, and it’s currently available at an impressive discount of 46%, bringing the price down to $299 from its original list price of $549.
