Claim 10:
11. A vacuum cleaner configured to be combined with modular cleaning modules, the vacuum cleaner comprising:
a driver configured to transmit a suction force to a cleaning module in use;
a sensor configured to obtain sensor information indicating at least one of current, voltage, load, or torque for the cleaning module;
a memory configured to store information regarding pre-registered cleaning modules and last used time information of the cleaning module;
a processor configured to identify the cleaning module by comparing the information regarding pre-registered cleaning modules with the sensor information;
a first wireless transmitter configured to transmit information related to the identified cleaning module to a server; and
a usage mode selection unit configured to provide a plurality of usage modes that vary the suction force of the driver,
wherein the memory is further configured to store usage time information for each usage mode for the cleaning module in use,
wherein the transmitted information related to the identified cleaning module includes the usage time information for each usage mode, and
wherein the processor is further configured to:
convert the usage time information by applying a weight for each usage mode to generate converted information; and
