Holey-Moley Vacuum Assisted Post Hole Digger is easy to operate

The easily assembled parts when hooked up to a standard shop vacuum cleaner become a robust, simple to use, hole-boring machine. When finished the digger will look like the fully assembled digger in the product gallery. You will need a Shop Vacuum described in our section on Selecting a Shop Vacuum. We also have a blog on Digging Holes With A Shop Vac

As a result of excellent engineering the Digger  is easy to operate. Therefore , it only requires an easy back-and-forth rotational movement to loosen the soil. The unique design results in your shop vacuum doing the hard work. Also, unlike a post hole auger that leaves a lot of soil around the hole, the shop vac removes the soil from the hole while digging making this digger ideal for golf greens and turf grass.   The vacuum also works well for cleaning up the bottom of the hole when digging is complete.

Get better performance out of your shop vacuum with low loss hose.

The Holey-Moley Diggers work on air flow and more importantly air velocity.  Its the velocity that picks up and moves the dirt particles generated in the digger head.   Therefore, to get more velocity and airflow from your shop vacuum use our Low Loss Vacuum Hose. This low loss vacuum hose will increase the flow rate of your shop vacuum by 20% over that of standard shop vacuum hose.   It is all those ripples in the hose that causes resistance to flow.  The low loss vacuum hose is smooth inside.  Not only does this increase the flow rate, but also minimizes particles from hanging up inside.  Best of all this vacuum hose is easy to clean by just washing out.

No matter the name, post hole vacuum auger, or post hole digger, if it uses a vacuum hose, this is the best hose to use.
