What does J.O.O.N.A.S do in Moon Sweepers?

Does one robot clear the whole moon?

The write-up says J.O.O.N.A.S cleans the whole moon one hex at a time, nearest dusty hex first, and throws capsules toward the emptiest catcher it can use. That is a coverage claim, not a timer. Searches ask how long one unit takes per hex or per sector. Neither the Fextralife page nor the PlayerEcho page printed a second count. I am leaving the duration blank rather than turning a question into a fake stopwatch.

A catcher is the other half of the purchase. It is listed at $1,500. If every catcher is full, the robot waits. People who buy the arms and skip the catcher own a $20,000 statue. Vacuum robots, the Mk I and Mk II rows, are smaller dock units. I do not treat those names as aliases of {bot}. They stay on the robot overview until two pages agree they are the same object.

Upgrades and whether it is worth it

Upgrade steps for this robot are a popular query and are not itemized with prices on the pages I used. The blank stands. Against a Stone Press at $1,000, this is a late purchase: you already need dust income, a catcher, and somewhere for 20 kg capsules to land. I would fund presses and panels before I fund the arms, because the presses have a printed cycle and this robot does not. The video I link is a tips upload from 25 Oct 2026, useful as a tour, not as a second timer.
