The IROBOT ROOMBA 780 model is flagship, it refers to the average price segment. At a height of 9.5 cm and a diameter of 34 cm, it weighs 4 kg. On the upper «bumper» there is a sensor, which is designed to determine obstacles. Since the robot always goes only forward, then before a collision with furniture and other objects, it slows down the course so as not to damage the surface of the interior object. Then it unfolds smoothly, moving around the object, and again gains speed. The clamp on the right surface disconnects the container with dust. The power and cleaning button is in the middle. Separately there are buttons for controlling the robot through the DU and to send the robot to the base.
