Vacuum cleaner
First Claim
1. A vacuum cleaner comprising:
- a cleaner body;
a moving wheel that is located at a side surface of the cleaner body, that is configured to support the cleaner body, and that is configured to rotate about a center axis of the moving wheel based on the vacuum cleaner moving in a forward direction or a reverse direction;
a wheel motor assembly that is connected to the moving wheel and that is configured to rotate the moving wheel;
a main motor that is located inside the cleaner body, that is located between a rear of the vacuum cleaner and the center axis of the moving wheel, and that is configured to generate a suction force; and
a battery that is located inside the cleaner body, that is located between the rear of the vacuum cleaner and the center axis of the moving wheel, and that is configured to provide electric power to the main motor and the wheel motor assembly,wherein a center of gravity of the cleaner body is located between the rear of the vacuum cleaner and the center axis of the moving wheel.
