Abstract: A robot cleaner including a body, a driven wheel, and a side brush coupled to the body. The side brush includes a hub configured to rotate about a pivot axis and a plurality of bristles. Some bristles may form a first angle with the pivot axis and others form a second angle with the pivot axis which is larger than the first angle. Some bristles may have a first bristle length and others have a second bristle length which is larger than the first bristle length. The robot cleaner may include a side brush deflector to deflect debris propelled by the side brush towards the vacuum inlet. The side brush deflector includes a plurality of deflector bristles extending downwardly from a floor facing surface of the robot cleaner towards a floor such that some of the bristles pass through or underneath a portion of the deflector bristles.
