If there are small vibrators that we could put under the bags in the carts, we might be able to somewhat automate the agitation and avoid having to pull the carts to do this.

This is the kind of gizmo that's built into cellphones to implement "silent" mode. I don't know whether it's actually enough vibration, but it's relatively cheap, and could probably just be hot-glued to the bottom of an inkjet cart. It looks easily controllable with a microcomputer like an Arduino. I could imagine a fairly simple system that would run automated, scheduled vibrations to a set of carts.
