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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
