Claim:
1. An apparatus for cleaning above and within an aqueous body, comprising: a fluid inlet receiving a pressurized cleaning fluid from a pressurized fluid source; a drain conduit receiving waste fluid from said aqueous body and discharging said waste fluid externally therefrom; a tank flush source conduit coupled with said fluid inlet and operative to conduct said pressurized cleaning fluid from a tank flush source conduit inlet adjacent said fluid inlet to a tank flush source conduit outlet distal to said fluid inlet and within said aqueous body; and a siphon return conduit concentrically arranged about said tank flush source conduit for conducting said waste fluid from a siphon return conduit inlet opening within and generally surrounded by said waste fluid in said aqueous body to a siphon return conduit outlet adjacent to said drain conduit and conducting said pressurized cleaning fluid into said aqueous body simultaneously with said siphon return conduit inlet conducting said waste fluid out of said aqueous body, said tank flush source conduit outlet protruding from said siphon return conduit inlet and blocking said siphon return conduit inlet from being held by vacuum against a surface on an interior of said aqueous body while simultaneously developing an eddy current entraining waste fluid and matter therein.
