Disclosed is a self-propelled cleaner that can reduce power consumption and that is economically advantageous. The self-propelled cleaner normally detects an intruder using pyroelectric sensors that consume less power, and each time a predetermined period of time has passed, detects an intruder with the infrared CCD sensor while turning the body BD. This can reduce the time of operation during which the infrared CCD sensor consuming more power is used, thus making it possible to reduce power consumption. Moreover, since the self-propelled cleaner is designed to cause the drive mechanism provided therein to turn the body BD, it is not necessary to additionally provide a device to turn the infrared CCD sensor, thus reducing the manufacturing cost. |
