This is one of the coolest features I’ve seen on a robot vacuum. The side arm actually swings out to reach edges and corners instead of just hoping the brush gets close enough.
You can see it extend when it gets near baseboards and furniture, and it actually pulls debris out instead of leaving that thin line behind. Most robots just kind of miss that area.
Between this and how precise the navigation is, it feels way more intentional about cleaning instead of just roaming around.
