Pool cleaning head

A device for automatically cleaning swimming pool surfaces, said device being adapted for use in a swimming pool cleaning system including a high pressure source which cycles water pressure applied to said device, said device comprising in combination:

• a base, said base having an upper surface, a recess in said upper surface, and an opening for conducting water from said high pressure source into said recess;
• a cover, said cover being connected to said base to form an interior chamber bounded by said recess and a plurality of outlet ports disposed peripherally about said chamber for conducting jets of water outwardly from said device along an inner surface of said swimming pool;
• and
• rotating means disposed in said chamber for receiving water forced into said chamber from said high pressure source and guiding water into various ones of said outlet ports as water pressure from said high pressure source is cycled, said rotating means rotating in response to water ejected non-radially from said rotating means, said rotating means expanding in response to pressure of water forced through said chamber to frictionally engage the walls of said chamber, randomly stopping rotation of said rotating means as the water pressure is cycled.
