That's not a bad question. Thing is the organisations that perform thorough civilian demining already start off with cheaper methods such as mine rollers to get some of the mines, and the ones they use are arguably cheaper to use because they're strong enough to require fewer replacement parts. For instance Mechem has a CASSPIR armoured vehicle with steel wheels that'll happily trundle over anti-personnel mines all day without needing repairs (though anti-tank mines necessitate a wheel change). And as another poster (codebeaker) pointed out, it's also far worse for demining teams to have random shrapnel spread over a minefield, as it makes the job of identifying mines much more difficult. That's one of the reasons why demining teams use systems that are less likely to break and leave pieces on the minefield. So it's unlikely that this product will save any money.
