The Capsule Catcher is one of the more useful buildings you can add to a late-game Moon Sweepers operation, particularly once JOONAS starts collecting dust across the lunar surface. Rather than bringing every load back yourself, you can set up a system that receives capsules remotely and sends them toward your station. Getting everything working requires a few connections, though, and the Catcher has a specific role that makes it different from your other collection equipment.

What Does the Capsule Catcher Do in Moon Sweepers?
The Capsule Catcher is a $1,500 building that receives dust capsules launched by JOONAS, the automated cleaning robot. When JOONAS has collected dust and needs to unload, it sends its capsules toward the nearest Capsule Catcher instead of requiring you to retrieve the material yourself.
Those capsules can then enter a connected Conveyor system, allowing the collected dust to travel back to your station for selling.
The Catcher doesn't clean lunar dust or produce capsules independently. Its job is to receive materials from JOONAS and provide a connection to the rest of your transport network.
This is also why simply purchasing a Capsule Catcher won't generate any income. You'll need JOONAS collecting dust and a working route for those capsules to reach their destination.
Does JOONAS Need a Capsule Catcher?
Yes, if you want JOONAS to unload its collected dust automatically.
JOONAS costs $20,000 and operates as a mobile automated cleaner, moving between dirty sectors rather than remaining within the fixed coverage area of a Robot Vacuum dock.
When its dust storage fills, JOONAS relies on a Capsule Catcher to receive the material. Without one available, it can end up waiting with a full load instead of continuing its cleaning routine.
The two buildings therefore work together, with JOONAS handling collection and the Capsule Catcher handling reception.
For more on setting up the robot itself, including its cleaning behavior and how it handles collected dust, check our Moon Sweepers JOONAS Guide.
How to Use the Capsule Catcher in Moon Sweepers
To use a Capsule Catcher, you'll need JOONAS, the Catcher itself, and a Conveyor connection for transporting the received dust capsules.
- Purchase JOONAS for $20,000 through the construction system.
- Build a Capsule Catcher for $1,500 in a location suitable for connecting to your existing Conveyor network.
- Connect the Catcher's capsule output to a Conveyor leading toward your station.
- Make sure the Conveyor continues all the way to the station's intake.
- Allow JOONAS to clean lunar dust until it's ready to unload.
- Watch for capsules being launched toward the nearest Capsule Catcher.
- Confirm that the received capsules continue along the Conveyor toward the station.
You don't need to manually collect the launched capsules and carry them back once the transport system is working.
I'd place the Catcher with the outgoing Conveyor route in mind. Having it conveniently located near your existing infrastructure makes more sense than placing it somewhere that requires an unnecessarily complicated connection back to the station.
If you eventually build additional Catchers, remember that JOONAS sends capsules toward the nearest one. Your receiving locations should therefore have working outgoing routes rather than simply being scattered across the Moon.
How to Automatically Sell Dust From the Capsule Catcher
The Capsule Catcher receives capsules, but it doesn't sell their contents by itself.
For automatic selling, you'll need a Conveyor carrying those capsules into the station's intake. Once the dust reaches that destination, the sale is completed and the money is credited.
The complete setup follows this route:
JOONAS collects dust → launches capsules → Capsule Catcher receives them → Conveyor transports them → station intake sells them.
Once you have that route working, JOONAS can continue contributing dust to your operation while you're busy with other tasks.
Before leaving everything running, I'd follow the first delivered capsule all the way to the station and check that the money actually arrives. Catching the capsule is only one part of the process; a disconnected Conveyor can still prevent the sale.
Our Moon Sweepers Auto Selling Guide explains how to connect conveyors to the station intake and troubleshoot deliveries that aren't generating money.
Capsule Catcher Not Working in Moon Sweepers?
If the Capsule Catcher isn't receiving dust or your JOONAS setup has stopped producing money, check which part of the process has stopped first.
JOONAS Isn't Launching Any Capsules
Make sure JOONAS is actually collecting dust and has a Capsule Catcher available for unloading.
If there isn't a receiving Catcher, JOONAS can remain stuck with its collected material instead of sending it into your transport system.
Patch 1.0.4 also improved JOONAS so it can continue cleaning when players move farther away. Older versions had problems with the robot stopping when nobody was nearby.
Capsules Are Reaching the Catcher but Going Nowhere
Inspect the Catcher's outgoing Conveyor connection.
If the capsules are being received but aren't traveling toward the station, check that the belt is connected, pointing in the correct direction, and leading somewhere that can accept the material.
Follow the route until you find the first location where capsules stop moving. That's where I'd focus on making repairs before replacing the Catcher itself.
The Catcher Works but You Aren't Making Money
Receiving dust and selling it are separate actions.
If capsules are successfully leaving the Catcher, follow them to the station and confirm they enter the intake. A Conveyor ending beside the station rather than inside its receiving connection can prevent your delivery from being completed.
Also check for backed-up capsules elsewhere in the network, particularly if you're using Mergers or sharing a delivery belt with other automated equipment.
Is the Capsule Catcher Worth Buying in Moon Sweepers?
The Capsule Catcher is worth purchasing when you're ready to put JOONAS to work. At $1,500, it's much cheaper than the $20,000 robot itself, but it's an essential part of turning JOONAS into a useful automated dust collection setup.
Together, the two cost $21,500, excluding any additional Conveyor construction.
For players who haven't purchased JOONAS, there's little reason to prioritize a Capsule Catcher. A Packager, Robot Vacuum, or Garage unloading system can already provide other ways to send dust into conveyors without using JOONAS.
Once you're ready for larger-scale automated cleaning, though, the Catcher gives JOONAS somewhere to send its collected material and provides the connection needed to feed that dust into your existing selling operation.
I'd treat it as part of the JOONAS purchase rather than a separate optional upgrade. With both buildings connected to a working delivery route, you've got a cleaner that can collect dust across the Moon and a receiving system that gets those materials back into circulation without repeated manual hauling.
