A compact mobile vacuum boring, and excavation method comprising a device which will create a vacuum condition within a vacuum container and having a vacuum conduit to air convey a liquid and or solid particles into the vacuum container. The vacuum container air inlet & outlet conduit arrangement may also facilitate the separation of solids from the vacuumed air flow by producing a cyclone effect within the vacuum container. A circular cyclone effect is created within the vacuum container by the arrangement relationship between the inlet and outlet vacuum air conduits and baffles. As the air velocity slows, the solids precipitate out of the air and settle in the vacuum container. A housing with filters disposed within it is also adjacently mounted near the vacuum container in order to reduce the quantity of connecting conduits and facilitate a compact, efficient and clean interaction between the vacuum container and the filter housing. The vacuum container access door and the filter housing access door may be adjacently placed in near proximity to each other for user friendly access to empty and clean the vacuum container and filter house or a common door may access both. A compressible seal and conduit arrangement may be used as a quick disconnect between the vacuum producing means and the filter housing. A reversing valve arrangement may be used to back flow air through the filter. Sensors, data gathering, data logging and documentation of a service event may be included. The above systems may be mounted on a variety of mobile platforms.
