Abstract: The majority of currently available, submersible swimming pool cleaners operate in a random manner, i.e. follow no set path of travel along the bottom of a swimming pool. The result is that a lengthy period of time and large power consumption are required to clean an entire swimming pool. This problem is solved by a swimming pool cleaner of the submersible type including a casing which tapers from one end to the other thereof, a pair of wheels at the wide end of the casing, a single wheel at the narrow end of the casing, a drive system for driving each of the wheels, a cable for connecting the cleaner to a fixed point on one side of the pool, a cable tensioning device in the casing for changing the length and tension on the cable whereby the cleaner is caused to follow a predetermined path of travel over the entire inside area of the swimming pool.
