摘要

To clean the swimming pool (10) a first rotating cleaning head (16,18,24,26) is placed in the bottom of the pool which effects cleaning over a 180o circle. A second rotating cleaning head (20,22,28,30) is placed in the pool bottom between each first head and a suction return (12) to carry out cleaning over a 180o arc directed towards the suction return. The heads are supplied alternately with pressurized water through a recycling pump circuit. An Independent claim is included for a pool cleaning system.
