Abstract A vacuum attachment (10) for an LHD (load, haul, dump) machine (1) includes a holding tank (14) for receiving waste material; mounts or horns (2) associated with the holding tank (14) for cooperating with an LHD fitting; a vacuum blower or liquid ring pump (16) in fluid communication with the holding tank (14); and connectors (5) for connecting the vacuum blower or liquid ring pump 16 to power from the LHD machine (1) for powering the vacuum blower or liquid ring pump (16). A method of collecting waste includes mounting the vacuum blower or pump (16) with the holding tank (14) on the LHD machine; connecting QDS (quick detach system) hoses to the vacuum blower or pump (16) to create a negative pressure inside the holding tank (14); connecting a hose to an inlet of the holding tank; and placing a hose end near the waste material to draw it into the hose.
