A suction excavator, or vacuum excavator, is a construction vehicle that removes heavy debris or other materials from a hole on land using vacuuming. Suction excavators are meant to be more non-destructive than regular excavators.^[1] The suction excavator uses suction fans for the airflow to suck up the material that is then transported into the holding tank.

Hydro excavation, a type of suction excavator using high-pressure water jets, is sometimes referred to as daylighting, as the underground utilities are exposed to daylight during the process.^[2] Some suction excavators also use an air filter.
