Object avoidance is a tough nut to crack on robot vacuums, but Narwal's new Flow 2 promises it has the best yet with a mix of on-board processing and AI cloud computing.

Narwal staggered announcements of the new versions of its two main botvac series: The newest Narwal Freo came out in September, and now, the Narwal Flow 2 is the flagship representing Narwal at CES 2026. The big difference is the roller mop.

At CES 2026, Anker debuted the Eufy S2, a powerful robot vacuum and mop hybrid that cleans your floors while also perfuming your home.
