Vacuum Excavators for Underground Utility Locating

VACMASTERS is the leader in air-vacuum excavation. Our systems use high-pressure air for excavating anything from small holes to large trenches at depths in excess of 10' for underground utility location, inspection, maintenance (keyhole technology). They are designed to help you locate underground utilities precisely, safely, and with no damage to the buried utilities, all advantages of potholing with air versus hydro excavating.

Air-Vacuum Excavation Systems

VACMASTERS engineers, develops, designs, and manufactures four major air-vacuum excavation systems:

System 6000 Air-Vacuum Excavator for potholing, trenching, and underground utility locating

SYSTEM 6000 -– the world’s most powerful air-vacuum excavation system and the first with the power to trench as well as pothole. 

System 5000 Air-Vacuum Excavator for potholing and underground utility locating

SYSTEM 5000 – substantially faster digging than the 4000 with a modest size and the added benefit of a full-opening rear door.

System 4000 Air-Vacuum Excavator for potholing and underground utility locating

SYSTEM 4000 – smaller and lighter in weight than the 5000, yet with the capacity to pothole in the hardest soils, including ground frost.

System 3000 Air-Vacuum Excavator for potholing and underground utility locating

SYSTEM 3000 – offers you a mid-priced system with big-time power. Highly maneuverable and easy to operate.

System 1000 Air-Vacuum Excavator for potholing and underground utility location

SYSTEM 1000 – our smallest air-vacuum system. Designed for trailer, truck or skid mounting, offering low cost, small size and high performance.


These air-vacuum excavation systems may also be used to remove excess directional boring slurry, or for a variety of other clean-out jobs, such as valve boxes, catch basins, etc. Check out a side-by-side comparison of our four air-vacuum excavation systems.

SpoilVac Mud Vacuum System

SpoilVac Hydro Excavation Mud Vacuum System: hydro excavator for directional boring slurry removal and clean out of valve boxes, catch basins, underground vaultsSpoilVac is VACMASTERS' mud vacuum for removing directional-boring slurry. This system also has an optional high-pressure water system for digging. The SpoilVac was designed primarily to vacuum up mud but can also perform limited potholing duties using high-pressure water only. Please consider however, that if your primary business revolves around locating underground utilities, we strongly recommend one of our air-vacuum excavation systems listed above, which are safer for the buried utilities and the operator, but can also be used to remove slurry.

Like all VACMASTERS' Vacuum Excavation Systems, SpoilVac is sold factory direct, saving you an average of 30% compared to buying one of our competitors' hydro excavators from a dealer. SpoilVac can be ordered online (click here), or by calling us directly at 1-800-466-7825.
