Abstract
A mobile robotic vacuum cleaner with obstacle sensing function is disclosed to include a machine body, a first running wheel and a second running wheel mounted in the machine body at two opposite sides in such a position that the extension line of the wheel shafts of the first and second running wheels divides the machine body into a front part and a rear part, and one or multiple rear obstacle sensors mounted in the rear part of the machine body to detect rear obstacles, avoiding the mobile robotic vacuum cleaner from falling down the stairs or dropping in a hole during its backward movement.
