VACUUM CLEANER
First Claim
1. A vacuum cleaner comprising:
- a cleaner body;
a suction hose that is located at a front surface of the cleaner body and that is configured to guide dust to the cleaner body;
wheels that are located at both sides of the cleaner body, that are configured to move the cleaner body by rotating, and that are configured to support the cleaner body;
wheel motors that are connected to the wheels and that are configured to rotate the wheels;
a detecting unit that is located in the cleaner body and that is configured to determine whether the cleaner is moving or stopped by sensing an inclination angle of the cleaner body;
a plurality of obstacle detecting members that are located at a front surface of the cleaner body, that are located at both sides of the suction hose, and that are configured to detect an obstacle; and
a controller that is configured to control the wheel motors based on signals from the detecting unit and the plurality of obstacle detecting members.
