Our pick for the best robot vacuum (or at least one of its many variants) is on sale. Amazon’s Black Friday deals include the Shark AI Ultra robot vacuum. The list price of this model is $599, but you can buy it for $250. That’s 58 percent off — and a record low.
One of the distinctive features of this model is its bagless design. Like many robovacs, it has an auto-empty station. But here, you can remove part of the base, dump its contents into the trash, and lock it back in place. The base retains up to 60 days of dirt and debris, and you’ll never need to order a bag refill.

The Shark AI Ultra has strong suction and good obstacle avoidance (via LiDAR). RoboVac cleans in a matrix grid. It auto-maps your home and supports Google Assistant and Alexa for voice control.
The runtime of the vacuum is approximately 120 minutes. (If it needs to stop and charge, it will automatically restart afterward.) Also note that this is a vacuum-only model: no cleaning here.
But if you’re interested in a robovac that also mops, or a cordless stick vacuum instead, Shark has other Black Friday deals as well. The Shark Stratos 2-in-1 Robot Vacuum and Mop is 55 percent off and down to $450 right now, while the Power Detect Pet Plus Cordless Vacuum with Self-Empty Base is down to $400.
