Robot vacuums are always big at CES. Narwal is trying to set itself apart with its Flow 2 robot vacuum. It'll utilize AI-powered cloud computing to enhance object avoidance. Unlike past robot vacuums, which may only be trained on 20 to 30 objects to avoid, the Flow 2 can send footage to the cloud and better detect almost anything. Its Baby Care mode will also lower the noise when vacuuming near cribs and can identify lost toys.
