1. An autonomous cleaning device for traveling on a working area surface, comprising:
a chassis and an upper housing secured to the chassis, wherein the upper housing comprises a forward portion and a rearward portion;
a buffer arranged along an edge of the forward portion of the upper housing, wherein the buffer is spaced away from the forward portion, and configured to output a buffer signal in response to a collision of the autonomous cleaning device into an object, an edge of the buffer and at least a part of an edge of the rearward portion form a circle;
a laser distance sensor comprising an emitting unit and a receiving unit, wherein the emitting unit and the receiving unit are spaced apart arranged, and configured to rotate to measure distance in all directions by receiving light spots reflected or scattered by obstacles or objects in a cleaning environment, the laser distance sensor is mounted on a top side of the upper housing so that no other structural features of the autonomous cleaning device interfere with the rotating of the emitting unit of the laser distance sensor;
a control system configured to control the movement of the autonomous cleaning device based on at least one of the buffer signal and the laser distance sensor signal,
wherein the autonomous cleaning device further comprises a protection cover to form a shell enclosing the laser distance sensor, and the protection cover is fixed in the autonomous cleaning device in such a manner that the protection cover is unable to move relative to the upper housing.
