Watch tiny swimming magnetic robots suck up uranium in a droplet of radioactive wastewater

Seems a bit arse backward to me.

If these collect the uranium by it simply sticking to them as they randomly move about would it not be simpler/more effective/economic to just coat some sort of surface or filter with the stuff the uranium sticks to and move the water rather making zillions of these robots which I presume would be dificult.
