Referring to FIG. 9, the automatic cleaner 10 according to the fourth exemplary embodiment of the present invention may clean the foreign matter of the cleaning surface 20 while moving in a state of being attached to the cleaning surface 20.

The front and rear parts of the automatic cleaner 10 may be provided with the contact detecting unit 160.

When power is applied to the first moving part 100 to drive the moving motor 135, the first moving part 100 moves toward the right direction.

In the process of moving the first moving unit 100, when the touch sensing unit 160 contacts the frame 25, the movement of the first moving unit 100 is stopped.

In addition, the first moving part 100 retreats in a direction away from the frame 25 (a direction).

In addition, when the direction change motor 142 is driven while the first moving part 100 is retracted, the first moving part 100 is rotated in the b direction.

Here, unlike the first embodiment, the first moving part 100 may rotate itself. The direction change motor 142 may be coupled to the first body 110 of the first moving part 100.

Here, the operation in which the first moving unit 100 retreats may be understood as an operation for securing a rotation radius of the first moving unit 100.

In addition, the moving motor 135 is driven again, so that the first moving part 100 moves downward by a predetermined distance.

The preset distance may correspond to the width or diameter of the first cleaning member 170. That is, after the direction change of the first moving unit 100 is made, the first moving unit 100 is moved by the width of the first cleaning member 170.

When the first moving part 100 is moved by the predetermined distance, the rotating plate 140 and the moving wheel 130 are rotated.

In addition, the first moving unit 100 is moved in a left direction, and when the touch sensing unit 160 contacts the frame 25, the movement of the first moving unit 100 is stopped.

Then, the first moving unit 100 is retracted and rotated again by a predetermined distance, and then moved downward.

Here, the first moving unit 100 may be moved by a predetermined distance as described above.

In this manner, the first moving part 100 may clean the cleaning surface 20 in a zig-zag manner while performing one-way movement and direction change.

130: movement wheel 150: first magnetic member
170: first cleaning member 200: second moving part
250: second magnetic member 270: second cleaning member
