ROBOROCK mainboard for robot vacuum (E4 Black, E5 White, E5 Black), 9.01.0618

ROBOROCK 9.01.0618 — mainboard for E4 Black, E5 White, E5 Black robot vacuum; weighs 0.07 kg. The mainboard is the robot's centre: navigation, motor control, dock communication and the app all run through it. If the robot will not start, stops mid-clean, loses its map or stops appearing in the app, the board is an early suspect — but check the battery, the ribbon cables and the charging contacts first. Fitting one is a repair job that involves opening the housing, and the machine usually has to be paired with the app again afterwards.
