  • the lateral plate 16 is inserted into the separating slot 722 of the first inducting member 72 to cut off the infrared, the first inducting member 72 sends a signal to the PCB 54 and then the PCB 54 sends an instruction to one of the gear-box member 52 connected to the PCB 54 to reverse the motor 53 according to the signal, thereby the cleaning portion 37 is reversed by the PCB 54 so as to form a movement direction of the cleaning robot 100 .
  • a corresponding second inducting member 74 sends a suspended signal to the PCB 54 , and then the PCB 54 controls the motor 53 to be reversed according to the suspended signal, thereby the cleaning robot 100 can avoid the steps or other ground structures with a drop.
