ABSTRACT:
A pool cleaner and method for removing debris from the surface of a pool. The pool cleaner comprises a body having an open first end, open body sides, and a filtration second end, the body being generally hollow to form a conduit for water and having a water supply member which may be operably connected to a source of pressurized water. The body is supported by support means so that the body does not substantially interfere with the circulation of water through the open first end, the open body sides, or the filtration second end. A filter net is attached to the filtration second end of the body and one or more water jets are operably connected to the body for propelling water substantially toward the filter net to direct debris into the filter net.
