Instead of 1 bristle brush, Roomba® robot vacuums use 2 Multi-Surface Brushes that flex to adjust to different floor types and avoid getting tangled with pet hair.

When driving across clean floors the Roomba will reduce suction power to save battery life, before turning everything up again at the next bit of dirt.
