connected to the return pipe of the pool circulation system so that the water being pumped back into the pool by the system was directed as jets into the pool and against the various surfaces thereof. Such sweep hoses are made flexible so as to whip and writhe around in the water as a result of the jet action of the water ejected through nozzles on the ends of the hoses.

These water jets served to disturb the dirt and other debris that has accumulated in the pool, and to place it in temporary suspension in the water for removal by the filtration system. That is, the suspended dirt is drawn out through the skimmer, skim gutter, or other outlet from the pool, and separated from the water intwo, of the wheels and having an inlet for attachment to the return of the water circulation system and an exhaust outlet for water that has passed through the turbine, and a steerable wheel for guiding the car about the pool. At least one sweep hose is attached to the car to direct water under pressure as a jet into the pool While moving sinuously about the car, and the guiding means is in the form of an endless steering element defining an endless track for the steerable wheel.

The preferred steering element is a weighted tube, and the steerable wheel has a peripheral groove for riding on the tube. Two sweep hoses of different lengths preferably are attached to the exhaust outlet of the turbine to receive water
