1. A mobile robotic vacuum cleaner, comprising:
- a machine body;
a first running wheel and a second running wheel mounted in said machine body at two opposite sides, said first running wheel and said second running wheel each having a wheel shaft, the extension line of the wheel shafts of said first running wheel and said second running wheel dividing said machine body into a front part and a rear part;
at least one front obstacle sensor mounted in said front part of said machine body and adapted for sensing the presence of an obstacle in front of said machine body;
wherein the mobile robotic vacuum cleaner further comprises at least one rear obstacle sensor mounted in said rear part of said machine body and adapted for sensing the presence of an obstacle behind said machine body.

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.
