First Claim
1. A vacuum cleaner comprising:
- a cleaner body;
a cover member that is located at an upper portion of the cleaner body and that is configured to open and close the cleaner body;
a suction hose that is located at a front surface of the cover member and that is configured to guide dust to 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 on a side of a front of the cover member and that are configured to detect an obstacle located in front or beside the cleaner body in the direction of the suction hose; and
