What JOONAS Does
JOONAS cleans one area at a time without a player driving it. Its collected dust is sent by capsule to a Capsule Catcher, so its output joins your normal production and selling loop.
- Reported cost: 20,000 per unit (third-party guide, October 26).
- Output: dust capsules that fly to the nearest Capsule Catcher.
- Scaling: each extra unit adds cleaning output; one Steam reviewer reported owning 260.
Known Quirks
The guide we checked warns that units may stop working if you move far away from them, and that they can get stuck or move in odd directions. Treat those as early-launch reports; check the latest patch notes before assuming a bug is still present.
Some reviewers say progression feels finished once JOONAS is running. Read how long to beat to see where it sits in a typical run.
Setting Up for JOONAS
Place Capsule Catchers near your production lines so capsules arrive close to where dust is processed. Start with one or two units and watch their first runs before buying more.
If capsules pile up, the bottleneck is usually further down the line. The Packager and conveyor checklist and depot guide cover those stoppages.
Frequently Asked Questions
Is JOONAS available in co-op?
Since patch 1.0.3 upgrades use the host's matrix across the crew. Purchases in a shared world benefit the whole crew.
Why did my JOONAS stop?
Reports mention units stalling when players move far away or getting stuck on terrain. Stay nearby and check for game updates.
