Abstract (en)
[origin: CA2558765A1] The invention relates to an immersed surface cleaning device comprising a filtering chamber (6) provided, through a lower rigid wall (8), with at least one liquid inlet (9a, 9b) which has a non-return unit, at least one filter (7) remote from each liquid inlet (9a, 9b) in such a way that a solid impurities retaining area (12) is defined and with a hydraulic circuit for forming a liquid flow by pumping means (4). At least one non-return unit comprises an anti-return conduit (20) which extends through the retaining area (12) away from the liquid inlet and whose free end (21) enters said retaining area (12), wherein the conduit is used for preventing at least the passage of impurities in an opposite direction from the retaining area through the liquid inlet at least when said pumping means is unused.
