What should I work on first?
Start with the early actions: clean a patch, deliver dust, launch a container and upgrade a brush. These establish the basic loop before you pursue large cumulative totals. The first vehicle and conveyor achievements give you useful next steps when carrying dust becomes repetitive.
The money achievements distinguish earning from spending. The map achievements distinguish regions or sections from percentages of the whole Moon. Use the exact requirement beside each name; a large account balance is not the same as total earnings, and buying all the equipment is not the same as cleaning the whole world.
One hidden conveyor achievement
The list includes a hidden requirement, kept behind a reveal control above so you can decide whether to read the spoiler. Use a separate small test when experimenting with belts; avoid rerouting a productive factory just to try an optional milestone.
Check Steam for the actual award. The boxes here are your notes, and a checked box does not send a completion request to the game. If Steam has not awarded something, compare the visible requirement with the action you completed before repeating it.
Source, scope and saved progress
The 33 names and requirements come from Steam’s public Moon Sweepers achievement data, checked on 26 October 2026. Grouping and guide links are editorial. No unofficial completion-time estimates, achievement unlockers or account connection are included.

If storage is unavailable, the checklist still works for the open page and tells you it cannot save. Clear saved progress removes only this checklist’s marks.
Reddit players and Steam reviewers describe a gap between developing an operation and finishing the global cleaning task. This checklist offers smaller, source-backed milestones without pretending to fix the game’s progression balance.
