Swimming pool cleaner
First Claim
1. A swimming pool cleaner of the submersible type comprising casing means;
- first wheel means on one end of said casing means;
second wheel means on the other end of said casing means;
brush means rotatably mounted on said casing means for dislodging dirt from a pool bottom;
pump means in said casing means for pumping water through said casing means;
filter means in the path of travel of the water pumped by said pump means for rotating said first and second wheel means and said brush means;
switch means for causing the drive means to reverse the direction of travel upon reaching a pool wall;
cable means for connecting said casing means to a point on the periphery of the swimming pool for causing the cleaner to follow an arcuate path of travel, the trajectory of the path being dependent upon the distance between the cleaner and said point;
winding means for changing the length of said cable means whereby the distance between said point and the cleaner is changed;
release means connected to said winding means permitting coiling or uncoiling of said cable means; and
spring means biasing said second wheel means to a turning position, whereby, by changing the tension on said cable means, while continuing to drive said wheel means, the cleaner can be caused to turn to effect corrections to the path of travel of the cleaner.

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.
