Therefore they do not work very well when working in shallow water. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The advantage of the power jet is that the operator of the dredge has to only deal with one hose when he is dredging. The answer is that they each have advantages and disadvantages. Which system is better - a power jet or a suction nozzle? A vacuum is created which sucks up water and gravel but the material is pushed through the hose instead of being sucked through the hose, as in the case of the power jet. Hoses and other dredge accessories are not included.Ī suction nozzle works in a similar fashion to a power jet except instead of being attached directly to the header box the nozzle is attached at the far end of the material hose.
