Claim 15:
16. A method of providing customized cleaning information associated with a vacuum cleaner having modular cleaning modules and a smart device on which an application linked to the vacuum cleaner is installed, the method comprising:
obtaining, by one or more processors, information related to a cleaning module from a sensor of the vacuum cleaner, the vacuum cleaner including a driver configured to transmit a suction force to the cleaning module,
transmitting, by the one or more processors, the information to a server through a transmitter,
determining, by the one or more processors, whether the cleaning module is in use from among pre-registered cleaning modules based on the information related to the cleaning module,
storing, by the one or more processors, last used time information of the cleaning module based on the information related to the cleaning module,
obtaining, by the one or more processors, current time information,
comparing, by the one or more processors, the last used time information with the current time information to determine whether unused time of the cleaning module exceeds an unused time threshold specified for the cleaning module,
providing, by the one or more processors, to the smart device, an indication that the cleaning module needs to be used when the unused time exceeds the unused time threshold,
separately storing, by the one or more processors, last used time information for a plurality of usage modes of the cleaning module based on the information related to the cleaning module,
applying, by the one or more processors, a weight for each usage mode of the cleaning module to each of the last used time information for the plurality of usage modes of the cleaning module stored separately,
storing, by the one or more processors, the last usage time information applied with the weight; and
transmitting, by the one or more processor, a control command to the vacuum cleaner and controlling an operation of the driver according to the control command, the control command being based on the last usage time information applied with the weight.
