1. A pool sweeper for removing debris from underwater, comprising:
a pump housing, said pump housing including a pump chamber inside said pump housing, said pump chamber for pulling water into said pool sweeper; said pump housing including a first end and a second end; a connection port as part of said second end of said pump housing, said connection port providing entrance to said pump chamber; a pump shaft movably mounted to said first end of the pump housing, said pump shaft mounted such that said pump shaft moves in and out of said first end of the pump housing and thereby moving in and out of said pump chamber, said pump shaft having a first end inside said pump chamber and a second end outside said pump chamber, said pump shaft including an opening at said first end of said pump shaft that is open to said pump chamber, said pump shaft including an open passage leading from said opening at said first end of said pump shaft; a release opening outside said pump housing that is connected to said open passage of said pump shaft, said release opening being closable to provide pressure during pumping; a pump handle attached to said second end of said pump shaft to provide a hand hold to actuate movement of said pump shaft; a plunger attached to said pump shaft that is within said pump chamber, said plunger including a plunger seal about said plunger to interact with an inside wall of said pump housing which forms said pump chamber, said plunger and plunger seal forming sealed separation between said first end and said second end of said pump housing within said pump chamber; a bag extension attached to said connection port, said bag extension including a first end and a second end with an open passage between said first and said second end of said bag extension, said first end and said second end of said bag extension being open and adapted to allow the entrance and exit of water and debris between said first end and said second end of said bag extension, said first end of said bag extension adapted for use of collection of water and debris, said second end of said bag extension for connection to said connection port of said pump housing, a first collection one-way valve which opens during pulling of said pump shaft away from said connection port of said pump housing adapted to allow pulling of water and debris into said bag extension and which closes during pushing of said pump shaft toward said connection port of said pump housing, said first collection one-way valve mounted inside said bag extension near said first end of said bag extension to open and block movement at said first end of said bag extension; a collection port connected to said bag extension between said first collection one-way valve and said second end of said bag extension, said collection port connected to said bag extension at a collection opening which is adapted to allow entrance of water and debris into said collection port when said pump shaft is pushed towards said connection port of said pump housing, said connection port including an exit adapted to allow exiting of water and debris from said collection port; a second collection one-way valve which opens during pushing of said pump shaft toward said connection port of said pump housing that is adapted to allow pushing of water and debris out of said exit of said collection port and which closes during pulling of said pump shaft away from said connection port of said pump housing, said second collection one-way valve mounted inside said collection port between said collection opening and said exit of said collection port, said second collection one-way valve mounted inside said collection port to open and block movement at said exit of said collection port; and a container connected to said exit of said collection port adapted to receive water and debris from said exit of said collection port, said container including a water release adapted to allow the release of water from said container when said container receives the water and debris from said exit of said collection port. |
