ABSTRACT:
A water driven pool cleaning device to sweep a swimming pool floor which includes a housing and a conduit to connect the housing to a water source. Water flow is directed through the housing and through a rotatable pair of arms, journaled for rotation above the housing, to distally arranged nozzles which are arranged to cause the arms to rotate and to cause debris on the pool floor to be flowed by water toward the housing. The housing defines a trap to collect the debris. The arms are connected to the housing so as to permit travel of a roller on the arms over the high and low areas of a pool floor.
