A sweeper, a server, a sweeper control method and a sweeper control system are disclosed by the present application, which belong to the technical field of smart home. The sweeper has: a main control module, and a detection module, a 5G communication module, a movement module and a cleaning module each connected to the main control module; wherein the main control module sends indoor data detected by the detection module to a server through the 5G communication module, and controls at least one of the movement module and the cleaning module according to a first instruction returned from the server. The sweeper of the present disclosure is capable of directly communicating with the server through the 5G network. On one hand, a large amount of complicated calculation may be performed in the server; on the other hand, the problem of inaccurate control of the sweeper is effectively avoided.
