Abstract
A pop-up cleaner for a swimming pool. The gear housing of the cleaner is removably positioned in a fitting in a circular opening in the floor of the pool. A jet block is mounted on a linear movable hollow tube that rotates with a rotor mounted in the gear housing, which rotor is connected through a reduction gear train mounted in the gear housing to an impeller mounted in a turbine casing on the gear housing. The fitting is adapted to be connected by a conduit to a water pump. When water under pressure is present in the conduit, the jet block projects out the fitting and a stream of water under pressure is directed substantially parallel to the surface of the pool in the vicinity of the cleaner. Water flowing through the cleaner rotates an impeller which through the reduction gear rotates the jet block at a substantially constant angular velocity. When the pump is turned off, the jet block returns into the fitting.
