Abstract:
A robot cleaner is provided. The robot cleaner includes a communication unit configured to communicate with the robot cleaner using a near field wireless communication (NFC) and a processor configured to detect a state of the robot cleaner among a plurality of predefined states. The processor is also configured to, in response to NFC tagging being performed with the mobile terminal, control the communication unit to transmit information corresponding to the detected state to the mobile terminal.

Abstract:
Disclosed is a method for providing information in a server. Said method for providing information in a server includes: a step for repeatedly receiving at preset intervals, data related to a plurality of sensors provided in an electronic device; a step for storing the data received at the preset intervals; a step for comparing data corresponding to a first period and data corresponding to a second period among the stored data, and thereby sensing a change in the performance of the electronic device; and a step for providing guidance information corresponding to the sensed change in performance to a user terminal device which corresponds to the electronic device.
