摘要： A cleaner is provided and includes a cleaner main body including a suction motor, a battery module and a control module configured to control an operation of the cleaner. The control module is mountable on and separable from the cleaner main body. The control module includes a main processor configured to communicate with the battery module at a preset interval in a state in which the control module is mounted on the cleaner main body. The battery module is configured to identify that the control module is separated from the cleaner main body and to stop a supply of power to the cleaner main body based on not receiving a communication signal from the control module for the preset first time period or longer.
