The Roomba 694 robot vacuum drops to a record low of $180

We recommended the $275 Roomba 694 in our budget robot vacuum guide because it did a good job cleaning hard and carpeted floors and has a straightforward mobile app experience that even newbies will learn quickly. Now, you can grab that robo-vac at the best price we've seen it -- an early Black Friday sale at Amazon has knocked the Roomba 694 down to $180, or $94 less than usual. This model just came out earlier this year and it replaces the older Roomba 675. The two vacuums are mostly the same, albeit for the refined design on the Roomba 694. It's a sleek, all-black robot with three buttons on its top in the center, which allow you to manually control it whenever that's easier than using the companion mobile app.
