Suction power!! If the hole is large enough for the item to get back into the space, the hole might be large enough for the hose as well.
I retrieved two high-quality pairs of hiking sock liners this way yesterday. I didn't even know anything was back there, behind the water heater. But if a hole exists, chances are good that something has made its way into it.
Great idea - never thought about using a vacuum. Next time I'll try it.
