Part of the beauty of this film is where Jarmusch leaves each story. He's rarely been one for buttoned-up conclusions. And here, he essentially offers not even a day, but a few hours in the lives of people bound by blood, and — what else? We get a window into their lives, and a glimpse of how they see each other.

Flipping the robovac over, there's another Shark classic underneath: The singular flat mopping pad... again. Shark is the only big robot vacuum brand that hasn't branched out to dual spinning mop pads (elite corner mopping) or a roller mop (elite spill soaking) in at least one model. But there are a few special features baked in to separate this Shark from the basic vacuum mop combos.
