Inspired by this tileable geode washing blueprint. After being too intimidated by the recipe for advanced circuits I instead spent way too much time creating a way to wash geodes that doesn't involve the advanced circuits or fancy alloys.
The robobox and robohub seem to need around 400 cargo robots mk 1 on average, I tossed in 400 and it seems to consistently use 350/400, peaking to around 380/400 in some cases. Ceramic filters are required, I gave 3 per filtration plant and it seems to work pretty well.
