Vacuum attachment including a pressurized air source

A vacuum attachment comprising:

• a body including:
• an adaptor configured to connect to a vacuum assembly,
• a vacuum airflow path configured to be in fluid communication with the vacuum assembly, and
• a dispensing airflow path, distinct from the vacuum airflow path, in fluid communication with a pressurized gas source, distinct from the vacuum assembly, wherein the dispensing airflow path and the vacuum airflow path are in a fixed directional relationship with respect to each other, such that an inlet to the vacuum airflow path into which air flows from an ambient source is adjacent to an outlet from the dispensing airflow path from which air flows into the ambient source such that air flowing into the vacuum airflow path moves in a direction opposing air flowing from the dispensing airflow path, and wherein the vacuum airflow path and the dispensing airflow path are isolated from one another such that air originating from the ambient source flows into the inlet and through the vacuum airflow path simultaneously and in isolation from gas originating from the pressurized gas source that flows through the dispensing airflow path into the ambient source.
