Agency Reviews Patent Application Approval Request for 'Adjustable Intake Port for Submersible Pool and Tank Cleaner'

摘要

From the background information supplied by the inventors, news correspondents obtained the following quote: "Automated or robotic swimming pool cleaners traditionally contact and move about on the pool bottom and wall surfaces being cleaned on four axle-mounted wheels, resilient rollers that are transversely mounted at either end of the unit, or on endless tracks that are powered by a separate drive motor through a gear train to propel the robot over the surfaces of the pool that are to be cleaned. The water pump can drive a water turbine connected via a gear train to the wheels or endless track. Robotic swimming pool cleaners have a pump motor that powers a water pump, which in turn causes the drawing of water through the moving unit, and the drawn, i.e., moving water dislodges and/or 'vacuums' debris up into a filter. The water pump can be internal or external to the robotic cleaner. For cleaning apparatus having an internal pump, the water exiting the cleaner in the form of a pressurized stream or water jet can also be used to move the cleaning apparatus by reactive force.
