pool during cleaning, and with at least one steerable Wheel 23 on the car for guiding it along the bottom surface. A motor 24 on the car is driven by water under pressure from the supply hose 19 and, in turn, drives the wheels 22. The steerable wheel 23 rides on an endless steering element 25 for guiding the car along a selected endless path around the pool. Thus, the car travels along a definite path along the bottom of the pool and carries the sweep hose or hoses along the path and within reach of all areas of the pool along the path.

In this instance, the car 20 is an elongated housing that tapers forwardly from a thickened rear portion to a relatively narrow nose at thereach from the car 20 to the sidewalls of the pool near the surface of the water, and also from the car to near the center of the pool.

With the car 20 in place on the tube 25, and with the rear wheels 22 straddling the tube and the grooved front wheel 23 resting thereon, all that is necessary to initiate operation of the pool cleaner 10 is to start the flow of water through the turbine 24. For this purpose, the supply tube 19 is inserted in the return pipe and the circulation system is put in operation. The flow of water through the turbine starts the car in motion along the tube, and the exhaust fiow from the turbine, exiting through the nozzles 53, produces two
