Provided is a washing machine which includes: a washing drum having an inner drum capable of rotating around an axis; a agitator capable of rotating in order to agitate the washings in the inner drum; a motor for rotating the inner drum and the agitator; a rotating mechanism; and a microcomputer. The rotating mechanism can rotate the washing drum about the axis in a manner of crossing with an up-down direction, so as to change a rotating angle of the washing drum. The microcomputer controls the motor and the rotating mechanism so as to execute washing operation for rotating the agitator in reverse or rotating the inner drum at multiple rotating angles.
