ABSTRACT:
A submersible suction cleaner includes a chamber, an oscillator pivotably mounted within the chamber for movement to and fro with a gap between an edge of the oscillator and a wall of the chamber through which water containing grit flows during operation. The chamber wall or the oscillator has a slidable, retractable seal operable to open when grit lodges between the oscillator and the chamber wall to thereby open the gap and allow the passage of grit therethrough.
