ABSTRACT:
The invention relates to a device for removing material from a submerged surface. The apparatus has a liquid manifold which supports downwardly directed liquid jets to dig or remove material and upwardly directed liquid jets to impel the removed material into the interior of a material removing housing and a gas manifold having a plurality of air jets to help urge the material into and through the material removing housing. Means are provided for dividing the liquid and gas manifolds into zones and for directing all of the supplied liquid and gas to one or more zones of the respective manifolds to either intensify and localize the effect of the fluids or to maintain the device in an operable condition when the source of gas and/or liquid is partially impaired.
