Systems for reducing or preventing pluggage of spoil material in an excavation vacuum apparatus wherein the pluggage prevention system of the excavation vacuum apparatus may trigger one or more mitigation operations (e.g., addition of water through spray nozzles) to loosen the build-up of spoil material and/or to at least partially shut down the excavation vacuum apparatus to prevent more material being fed to the system.
