A motor-driven appliance system in one aspect of an embodiment of the present disclosure includes a motor-driven appliance having a motor, at least one control circuit, and a communication device. The control circuit is configured to execute a process related to control of the motor-driven appliance. The communication device is configured to communicate with an external device. The control circuit is further configured to switch, when at least one predetermined sleep condition is satisfied, from an active mode in which the control circuit performs a normal operation to a sleep mode in which the control circuit stops part of the normal operation to thereby suppress power consumption; and to switch to the active mode when the communication device receives an external wakeup signal transmitted from the external device while the control circuit is in the sleep mode.
