1. A robotic cleaner comprising:
one or more driven wheels;
one or more environmental sensors configured to detect a corner region that is formed at an intersection of a first vertically extending surface of a first obstacle and a second vertically extending surface of a second obstacle;
one or more edge cleaning implements; and
a controller communicatively coupled to the one or more driven wheels and the one or more environmental sensors, the controller is configured to:
cause the robotic cleaner to follow the second vertically extending surface of the second obstacle in a direction of the first obstacle;
after at least one of the one or more environmental sensors detect the first obstacle, cause the robotic cleaner to rotate through a rotation angle according to a first rotation direction such that at least one of the one or more edge cleaning implements moves along the second vertically extending surface and away from the first vertically extending surface; and
after moving through the rotation angle according to the first rotation direction, causing the robotic cleaner to follow the first vertically extending surface of the first obstacle.
