After you’ve tried more than three or four robot vacuums (which I have), you become acutely aware of how hard it is to innovate within such a limited set of constraints. Robot vacuums all tend to be around the same size and shape. The dust bin and the ports are usually in the same place. Maybe the app looks a little different, maybe one has better mapping capabilities. Maybe one has sacrificed a little suction power to have longer battery life. Not so with the Powerbot R7065.
