Abstract: The present disclosure relates to self-diagnosis of a vacuum cleaner including a cleaner body and a brush device connected to the cleaner body. The cleaner body may be configured to perform self-diagnosis on each element of the vacuum cleaner by comparing a flow path pressure value of the vacuum cleaner which is detected by using a pressure sensor mounted to a portion of a suction duct and data related to a load of a brush device with reference values stored in a memory, and to output a result of the self-diagnosis.
