Abstract (en)
[origin: JPH04281967A] PURPOSE: To carry out optimum cleaning by detecting and avoiding an obstacle or the like in a device for cleaning a swimming pool. CONSTITUTION: When a front-side contact rail 18 is operated, a cleaning device 100 is rotated around the axis of the device in a plane until a rear-side switch rail 20 is operated. A signal being detected at that time is used to change a traveling device to retreat traveling and at the same time to straighten out the cleaning device 100 at a place where an obstacle exists. The signal related to the straightening-out is used for changing the traveling device to advance traveling. During a motion direction due to at least one sensor 25 being provided in a casing 1 of the cleaning device, an instantaneous motion direction regarding a running line or being directed toward a running zone-shaped part is detected. The amount of deviation being detected at that time is converted to the signal, and is switched to advance and retreat traveling for reciprocating in a swimming pool so that it can be used to correct direction motion.
