The operating principle provided by the disclosure is as follows. The robotic vacuum cleaner 1 receives the signals sent out from the four groups of the infrared emitting lights 10 on the dust collector 9 through the infrared receiving lights at six positions including the left front side infrared receiving light 2, the front side infrared receiving light 3, the right front side infrared receiving light 4, the left rear side infrared receiving light 5, the tail portion infrared receiving light 6, and the right rear side infrared receiving light 7. The robotic vacuum cleaner 1 receives the signals sent out from the four groups of the infrared emitting lights 10 in the dust collector 9 through the left front side infrared receiving light 2, two groups of the front side infrared receiving lights 3, and the right front side infrared receiving light 4. The robotic vacuum cleaner 1 continues moving towards the dust collector 9 and reaches a certain range in front of the dust collector 9 by avoiding the virtual wall signal transmitted by the virtual wall signal light 11. The robotic vacuum cleaner 1 continues moving towards the location of the dust collector 9. A distance between the robotic vacuum cleaner 1 and the dust collector 9 is detected through a distance sensor on the robotic vacuum cleaner 1, and the robotic vacuum cleaner 1 turns 180° at a position 300 mm away from the dust collector 9.

The dust collector 9 and the robotic vacuum cleaner 1 generate a charging current and perform charging to the robotic vacuum cleaner 1. The dust collector 9 issues a command to stop the robotic vacuum cleaner 1 from moving backwards. The robotic vacuum cleaner 1 transmits a signal to the communication receiving light 19 in the dust collector 9 through the communication transmitting light 16, and the dust collector 9 starts collecting dust after receiving the signal. The nozzle 13 on the dust collector 9 and the dust collecting opening 8 in the robotic vacuum cleaner 1 are attached and sealed.
