A vacuum cleaner control system by using a cellular phone is provided to stop a vacuum cleaner which is in operation during talking on the cellular phone. A vacuum cleaner control system by using a cellular phone(12) comprises a base station(11), the cellular phone, and a vacuum cleaner(21). The base station relays signals between cellular phones. The cellular phones include an RF transceiver unit(43), a control unit(41), a ringing unit(42), and a light emitting unit(44). The RF transceiver unit receives a signal delivered through the base station and processes the signal to a wireless data signal to transfer information to a receiver. The control unit of the cellular phone controls communication with the base station and ring of the cellular phone through the RF transceiver unit. The ringing unit makes cellular phone sounds with an incoming call transferred by the base station. The light emitting unit lights when the cellular phone rings. The vacuum cleaner includes a power unit(18), a speed control unit(17), a control unit(20), a sensing unit(19), a drive power sustaining unit, a switching unit(31), and a reset unit(27). The power unit of the vacuum cleaner unit converts and outputs voltage necessary to drive the vacuum cleaner. The speed control unit outputs a control signal to control the rotation speed of a motor through the control unit. The control unit of the vacuum cleaner receives the control signal from the speed control unit and accelerates or decelerates the motor. The sensing unit senses the light emitted by the light emitting unit. A signal converting unit converts the light signals into a current signal and inputs the current signal to the control unit to determine absence and presence of a sensing signal.
