The Holey-Moley Vacuum Assisted Post Hole Digger inventor is Titus Nelson, a registered Professional Engineer in California.  His professional license includes work in Alaska, British Columbia, Washington, Oregon, and Colorado. Ten years of his career includes deep shaft mining for atomic testing.  In addition, his experience includes digging tunnels for water and sewer projects.

His career also includes working as a Smokejumper fighting fires for the Forest Service and BLM.  His experience in the  Landscape Industry while attending college gave him extensive experience with other tools.  Additionally, as a Professional Mechanical Engineer in the Aerospace, Medical, and Semiconductor Industries,  he brings together a broad understanding of many different tools.

Titus Nelson also holds a patent on an automatic sandbag-filling machine capable of filling two sandbags a second. His familiarity with developing and using equipment for moving earth plays a key role in the developments of the Holey-Moley Vacuum Assisted Post Hole Digger.

The Digger

U.S. Patent No. 10,385,537 for the Vacuum-Assisted Hole Digger was issued on August 20, 2019 is the technological basis for the Holey-Moley Vacuum Assisted Post Hole Digger.  As a result, this unique patent covers the design of a hole-digger that fits in-between cheap post hole diggers and expensive industrial drilling equipment.  Consequently, a single person using the Holey-Moley Vacuum Assisted Hole Digger, can now dig straight, uniform holes up to 12-inches in diameter to depths exceeding 20-feet. The average person can dig holes to depths that far exceed that of the typical post hole diggers.  For those that want to dig in a remote location, the company offers a Portable Engine Driven Shop Vacuum System.

The Holey-Moley Vacuum Assisted Post Hole Digger has many different configurations.  Even more unique is the digger with a PVC pipe as the backbone of  the digger.  This digger, comes as a DIY kit and weighs more than the more robust metal diggers.  However, this less expensive digger is also capable of digging holes 6″ to 9″ in diameter to depths of 20 feet or more.

The Holey-Moley Digger is available preassembled or in a Do-It-Yourself kits

The Digger Has Many Uses

The Digger has a number of uses including:

  • Shallow Wells 
  • Cache Tube Burial 
  • Construction Pilings
  • Engineering Soil Sampling
  • Landscaping & Post Holes
  • Mining Core Sampling

How the Holey-Moley Vacuum Assisted Post Hole Digger Works

The Holey-Moley Vacuum Assisted Post Hole Digger has several unique properties.  First of all, it uses a standard shop vacuum cleaner to obtain super cyclonic wind speeds in the digger head.  Secondly, the super cyclonic airflow velocities are are under slight vacuum which increases the wind velocities.  Finally these high wind velocities make the digger suitable for excavating precision holes in hard packed clay, compacted soils with small rocks, sandy soils, and looms.

What You Need To Purchase

The Holey-Moley Vacuum Assisted Hole Diggers include everything except a Shop Vacuum. These vacuums are readily available at your local hardware store.  These as described in the Equipment Requirements page.

Due to the diggers unique design, a standard shop vacuum with a 2-1/2 inch hose is more than satisfactory for digging holes.  Likewise, the Holey-Moley Vacuum Assisted Post Hole Hole Digger can dig precision, smooth bored holes exceeding 20-feet deep.  Additionally with the use of hole reamers, diameters up to 12 inches are possible.  Further information can be found on our Blog for Selecting The Best Hole Digging Shop Vacuum, and for Digging Deep, Straight, Concentric Holes with a Shop-Vac.
