The Hopper Vacs have been in operation many places around the world. One of the best tests is when a large corporation puts it through its paces. That corporation was Canada's Darlington Nuclear Generation that operate nuclear power stations across Canada. They are very particular and demanding in what they require. Hopper Vac performed perfectly.

Testimonial: May 2009

By the way, today we spilled 600 lbs of aluminum oxide on to the floor and people started sweeping and moaning.
After questioning their intelligence I grabbed the hose of Beastly sucking Dog, ...it was 20 feet straight up (I measured) over a handrail and down to the hopper which was sitting on the same floor as the spill ...and cleaned up the entire mess in a matter of few minutes, with no hesitation or choking.
Very impressive!
Don’t know any other mobile unit that will do that!
But then....that’s why we came to you in the first place, because, quite frankly, you suck better than all the rest....and I searched long and hard before I concluded that you knew things that others did not................
