2.  Description of Related Art
As far as Applicant is aware, the existing vacuum heads which are known using water pool facilities i.e. city tap water having a municipal watertap pressure, and a water pump for pools, are provided only with suction or with suction and a brush.  Such devices, when used, give the impression of resulting in a clean pool.  However within a day, a suspension in the pool returns to the bottom, indicating that the dirt that was expected to be removed, was in part put in suspension during the cleaning process.
