Roomba j7+ vs Roborock S8 MaxV Ultra / Ecovacs: Roomba j7+ wins for cable avoidance

The Roomba j7+ with PrecisionVision is the only vacuum that reliably stops a millimeter from thin Lightning cables. Other brands like Roborock and Ecovacs detect obstacles but don’t specifically recognize cables as things to avoid — iRobot trained its dataset on cables of all thicknesses and colors, so the j7+ knows not to eat them.
