The Aardvark has a permanently charged magnet in it that weighs close to 600 lbs and with a magnet this big, clean off has to be automated in some way.
The Aardvark utilizes the simplest most proven and effective method of automating clean off which is to rotate the magnet around a pivot point on one side to rotate the magnet upward to physically separate the magnet from the debris.
To do this a 4000 lb winch is used. Rotating the magnet around a pivot point on one side takes less effort than lifting the magnet straight up and the 4000 lbs winch does this with no problem. The normal steel winch cable is replaced with an Amsteel blue synthetic winch rope in order to withstand more frequent unwinding and winding. A normal steel winch cable would fatigue and break with a limited number of uses.
The winch is designed to be powered by a deep cycle marine battery. A marine battery does not come with the unit but should be used instead of a regular battery because they are designed to be used in these circumstances much like they are used for trolling motors in boats. They can also withstand some bumping and bouncing.

It’s awesome, very pleased. Beyond the nails it was expected to pick up, it has picked up a three foot piece of rebar, circular saw blades, and hedge clippers.

Good morning Mike, I had my guy pull the road this morning, and this is what we picked up in only 1 pull.
I have decreased flats by more than 80% so far.
Thanks

Hi Mike,
I thought I would send you a few photos of one of the sweepers at work on the public road and the material collected.
We now sweep 66 Kilometers of the public road and we are already seeing a decrease in the incidents of punctures.

We made a video today for you. Our IT guy is going to see how to format it and get it to you. I think you will be quite happy with it. The unit works great.
