Abstract: A system for removing trash items from a space includes employing an autonomous robot to detect trash within the space, to approach the trash item upon detection and to remove the trash item from the space. The autonomous robot may have two or more trash bins with each trash bin being designated to be filled with a particular category of trash. The categories of trash may be different from one another. The autonomous robot is configured to detect the trash category of the trash item that will be picked up and, after picking up the trash item, to insert it in the appropriate trash bin. This way, the autonomous robot can collect and sort trash items according to their kind. A pan with sweeper arms can be used by the robot for collecting a trash item. In another approach, a trash item can be suctioned by the robot using vacuum.
