1. A vacuum cleaner comprising:

  • a cleaner body;

    a cover member that is located at an upper portion of the cleaner body, that is configured to open and close the cleaner body, and that includes a connector at a center of a frontal end of the cover member;

    a suction hose that is connected to the connector and that is configured to suck dust into the cleaner body;

    wheels that are located on both side surfaces of the cleaner body;

    a wheel motor assembly that is connected to the wheels and that is configured to, based on force applied to the suction hose, rotate the moving wheels to move the cleaner body in a direction of the suction hose;

    a plurality of obstacle detecting members that are located along an edge of the cover member, that are configured to detect an obstacle located near the cleaner body in a moving direction of the suction hose, that are located on a left side of the connector and a right side of the connector, and that include;

    front sensors that are located at the left side of the connector and the right side of the connector, that are configured to face a frontal area between a front side of the cleaner body and a lateral side of the cleaner body, and that are configured to detect an obstacle located in the frontal area; and

    side sensors that are spaced apart from the front sensors laterally and towards a rear of the vacuum cleaner, that are configured to face the lateral side of the cleaner body, and that are configured to detect an obstacle located at the lateral side of the cleaner body; and

    a printed circuit board (PCB) that is configured to control an operation of the wheel motor assembly according to a signal from the obstacle detecting member,wherein each of the front and side sensors have a detecting range of a preset angle, andwherein a detecting distance of each side sensor is shorter than a detecting distance of each front sensor.
