1. A vacuum cleaner comprising:
- a cleaner main body;
a suction device in communications with the cleaner main body;
a wheel to move the cleaner main body;
a motor to drive the wheel;
a sensor to detect a rotation angle of the cleaner main body;
a memory in which a plurality of reference angles are stored; and
a controller which determines one reference angle of the plurality of reference angles and controls the motor depending on a difference between the rotation angle detected by the sensor and the determined reference angle,wherein the controller determines the one of the plurality of reference angles after operating the motor to position the cleaner main body at each of the plurality of reference angles.

Abstract
A vacuum cleaner includes a cleaner main body; a suction device communicated with the cleaner main body; a wheel which may move the cleaner body; a motor for driving the wheel; a sensor for detecting a rotation angle of the cleaner main body about a rotation angle of the wheel; a memory in which a plurality of reference values about the sensor are stored; and a controller determining one reference value of the plurality of reference values and controlling the motor according to a size of an angle value detected from the sensor based on the determined reference value.

9. A vacuum cleaner comprising:
-
a cleaner main body; a suction device in communications with the cleaner main body; a wheel; a motor to drive the wheel to move the cleaner main body; a sensor to detect a movement of a detection target about a rotation center of the wheel; and a controller which determines one reference value of a plurality of reference values, each of the reference values being associated with a respective starting position for the detection target, and controls the motor according to a relative movement of the detection target based on the movement of the detection target detected by the sensor from the starting position associated with determined reference value, wherein the controller determines the one reference value of the plurality of reference values after operating the motor to position the detection target about each of the starting positions associated with the plurality of reference values, and wherein, when the detected value exceeds a forward reference value, the controller controls the motor so that the cleaner main body moves forward, and when the detected value exceeds a backward reference value, the controller controls the motor so that the cleaner main body moves backward.
