The invention, which belongs to the field of the communication technology and the control technology, particular relates to a mobile smart housekeeper comprising a movable platform, a master control unit, a WIFI module 1, a GSM module, and a security and protection module arranged in a household appliance. The master control unit, the WIFI module 1, and the GSM module are arranged in the movable platform in a built-in mode. The security and protection module consists of an infrared sensor, a light intensity sensor, a smoke detector, a temperature sensor and an anti-theft alarm. The master control unit is connected with the WIFI module 1 and the GSM module. The infrared sensor, the light intensity sensor, the smoke detector, the temperature sensor and the anti-theft alarm are provided with WIF modules 2 in a built-in mode and are connected with the WIFI module 1 wirelessly by the WIF modules 2. According to the invention, the high-performance microprocessor is used for replacing a PC machine and is used as the controller, so that housekeeper can work stably and reliably. Moreover, the mobile smart housekeeper has advantages of light weight, convenient movement, low power and low power consumption. In addition, falling down detection is carried out during the movement process, thereby realizing the electronic security function; and thus the household situation can be monitored in real time.
