Sweep The Moon Dust Processing: Machines and Lunar Converter
Last updated:
The Lunar Converter turns delivered moon dust into crew income. Keep dust moving by reducing conversion time, watching the processing queue, and repairing the machine when it breaks.

Processing Machines and Their Roles
The Lunar Converter handles dust conversion and sales income for the entire crew. Crusher and Block Press are buildable dust-processing machines.
For Factory Floor, build either a Crusher or a Block Press; you do not need both.

From Unloaded Dust to Crew Income
- Unload collected dust at a SELL pad, including the SELL area beside the Lunar Converter.
- Let the conveyor route carry unloaded dust to the converter.
- The converter packages incoming raw dust into capsules.
- The capsules travel out along a conveyor and sell, paying every crew member.
An empty container means unloading is complete, but payment can still be pending. Dust may still be traveling or waiting for conversion.
Open the converter menu and check the dust waiting for conversion. A queue that keeps building while dust arrives points to a processing bottleneck. Lowering Time per Dust helps the converter work through that queue sooner. For sale bonuses and other income choices, see the money guide.
Upgrade the Lunar Converter
- Approach the Lunar Converter and press E to open its menu. Alternatively, press Tab, open UPGRADES → GENERAL, and find CONVERT TIME.
- Check the current level, Time per Dust, and the next Cash upgrade price. The machine's menu also displays waiting dust.
- Buy the upgrade when you have enough Cash. Prioritize further upgrades when delivered dust keeps accumulating at the converter.

Repair a Damaged Converter
A damaged Lunar Converter stops processing dust. Restore it with the repair prompt:
- Stand beside the damaged converter and find HOLD E TO REPAIR.
- When repair is available, hold E.
- Keep repairing until the repair-success notification appears. The converter can then resume processing.
If repairs are unavailable during an active Goblin Raid, wait for the goblins to retreat, then use the repair prompt. The damaged machine also displays an automatic-repair countdown, giving you another way for operation to resume if manual repair does not restore it.
Choose the Right Dust-Handling Upgrade
Choose your next purchase according to where dust is waiting:
| Situation | Best next action | Why it helps |
|---|---|---|
| Dust is still traveling toward the converter | Upgrade conveyor speed | Shortens the transport stage |
| Delivered dust is piling up in the converter queue | Upgrade CONVERT TIME | Reduces processing time per dust |
| The converter is broken | Repair it | Restores processing |
For unloading farther from base, use the conveyor guide to choose and extend a route with a remote SELL pad. To combine collection facilities with transport and processing, follow the automation setup guide.
Goblin attacks can damage the converter; the base defense guide covers fighting raids and waking Moon Guards. If your next goal is a construction achievement, see Factory Floor and the other badge requirements.
