Abstract
Abstract A rotating platform is provided with water jets directing water therefrom so as to have a horizontal component of velocity tangential to the platform resulting in the rotation of the platform. An inflexible supply conduit is connected at one end thereof to the platform and is provided with a water jet at its opposite end to urge the platform into contact with the pool side while simultaneously providing water to the jets mounted on the platform. A flexible conduit is connected to the pool pump and to the inflexible conduit to supply the latter with water under pressure for operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
152 words
A pool cleaning device comprising: a rotatable floating platform having a vertical axis of rotation; at least one water jet mounted on said platform to direct water therefrom, the water being directed by said water jet with a horizontal component of velocity tangential to said floating platform to rotate said platform; means urging said floating platform to contact the sides of said pool, said means including an inflexible supply conduit rotatably connected at one end thereof to said platform and having an orifice at another end thereof to direct a stream of water therefrom, said supply conduit having a horizontal offset between the ends thereof; a source of water under pressure; a flexible conduit connecting said source to said inflexible supply conduit; and including a second inflexible supply conduit connected to and forming an angle with said first mentioned inflexible supply conduit between the ends thereof, said angle being less than 45*.
Claim 2
Dependent Claim
152 words
A pool cleaning device comprising: a rotatable floating platform having a vertical axis of rotation; at least one water jet mounted on said platform to direct water therefrom, the water being directed by said water jet with a horizontal component of velocity tangential to said floating platform to rotate said platform; means urging said floating platform to contact the sides of said pool, said means including an inflexible supply conduit rotatably connected at one end thereof to said platform and having an orifice at another end thereof to direct a stream of water therefrom, said supply conduit having a horizontal offset between the ends thereof; a source of water under pressure; a flexible conduit connecting said source to said inflexible supply conduit; and including a second inflexible supply conduit connected to and forming an angle with said first mentioned inflexible supply conduit between the ends thereof, said angle being less than 45*.
Claim 3
Dependent Claim
186 words
A pool cleaning device comprising: a rotating floating platform having a vertical axis of rotation; at least one water jet mounted on said platform to direct said water therefrom against the pool side for cleaning the side immediately above the water line, the water being directed by said water jet with a horizontal component of velocity tangential to said platform; means urging said floating platform in contact with the sides of said pool, said means including an inflexible supply conduit rotatably connected at one end thereof to said platform and having an orifice at another end thereof to direct a stream of water therefrom, said supply conduit having a horizontal offset between the ends thereof so that the direction of the force resulting from the stream of water directed from said orifice is offset from said axis of rotation; a source of water under prEssure; a flexible conduit connecting said source to said inflexible supply conduit; and including a second inflexible supply conduit connected to and forming an angle with said first mentioned inflexible supply conduit between the ends thereof, said angle being less than 45*.
Claim 4
Dependent Claim
