Spore Washer Overview & Function
The Spore Washer serves as a critical mid-game processing unit in Sandustry, designed to purify resources that have been contaminated by biological or environmental spores. Unlike standard filters that sort by size or type, the Washer actively alters the material state using liquid interactions. This machine is essential for players expanding into Plant-Rich Areas or deeper strata where raw resources are rarely pristine.
Build the Spore Washer close to your water source to minimize pipe length and reduce the energy required to pump liquids uphill.
To function, the machine requires a steady input of Water and the target Solid Resource. The falling-sand physics engine simulates the washing process, where water physically displaces the spore contamination. The output is a clean resource variant that can be used in advanced Production Chains or sold for higher value compared to its contaminated state.
| Feature | Description | Impact on Factory |
|---|---|---|
| Liquid Input | Requires active water supply via pipes. | Necessitates dedicated pump infrastructure. |
| Solid Input | Accepts contaminated sand, ore, or soil. | Should be fed from mining output lines. |
| Physics Process | Water interacts with particles to remove spores. | Generates wet byproducts; requires drainage. |
| Clean Output | Produces high-purity resource variants. | Unlocks advanced crafting tiers. |
| Automation | Supports continuous processing with logistics. | Replaces manual cleaning methods. |
Construction Requirements & Placement
Placing the Spore Washer requires careful planning regarding terrain and logistics. Since it involves both solid transport and liquid plumbing, it often acts as a bottleneck if positioned poorly. Ideally, it should sit between your Mining Excavation site and your main Storage Silos.
Secure Water Access
Identify a reliable water source, such as an underground aquifer or surface lake. Ensure you have unlocked Pipes and Pumps technology to transport water to the machine location.
Prepare Solid Input
Construct a Conveyor Line from your mining head or storage area to the Washer's input port. Install a Filter beforehand to separate large rocks that might jam the washing mechanism.
Place the Machine
Position the Spore Washer on a flat, stable tile. Leave one tile of space behind it for output collection and at least two tiles below for potential water drainage or overflow.
Connect Logistics
Link the clean output to your processing chain. Use a Launcher if the next processing station is across a gap or in a different factory module.
Manage Waste
Create a runoff pit or drainage channel for the used water and biological sludge byproducts to prevent them from flooding your factory floor.
Avoid placing the Washer directly above critical electrical components or Energy generators, as leaking water physics can short-circuit machinery.
Optimization & Production Strategies
Maximizing the throughput of your Spore Washer involves balancing the input flow of solids with the pressure of the liquid. If water input is too low, the machine will jam with dry, contaminated material. If solid input is too fast, excess water will flood the output chamber.
Balanced Flow
- Sync Conveyors with pump speed.
- Use Gates to regulate solid input.
- Prevents flooding and jamming.
High Throughput
- Stack Washers vertically.
- Use gravity to assist water flow.
- Requires robust drainage.
Compact Design
- Side-loading input pipes.
- Fits in narrow factory shafts.
- Harder to access for repairs.
Advanced Strategy: Integrate the Washer into a Modular Production Block. By pairing it with a Filter and a Storage unit, you create a self-cleaning station that automatically converts dirty mining output into premium factory inputs without manual intervention.
| Strategy | Setup Complexity | Throughput | Risk Level |
|---|---|---|---|
| Single Line | Low | Medium | Low |
| Parallel Array | High | Very High | Medium |
| Recycling Loop | Medium | High | High (Flood Risk) |
| Gravity Fed | Medium | High | Low |
Integration into Factory Layouts
The Spore Washer is not a standalone machine; it is the bridge between raw exploration and high-tier Factory Automation. Its placement dictates how efficiently you can transition from early-game resource hoarding to late-game systematic production.
Aim to place the Spore Washer in a dedicated "Hydro-Processing" zone, separated from dry logistics to keep water physics contained.
When connecting the Washer to the broader factory, consider the Material Flow. Cleaned resources should ideally move immediately into Heat Processing or Advanced Crafting stations. If the clean output sits idle, you are losing potential efficiency. Use Drones to move cleaned resources to distant parts of the factory if conveyors are impractical.

Progression & Completion Goals
Utilizing the Spore Washer is often tied to specific Factory Promotions and Steam Achievements. Moving beyond manual washing to automated hydro-processing is a significant milestone in Sandustry.
Spore Washer Milestones:
- Unlock Pipe and Pump technology
- Construct the first Spore Washer
- Automate water supply to the machine
- Connect output to main storage
- Process 1,000 units of contaminated material
In the context of Energy and Aura progression, the resources cleaned by the Washer are often required components for high-tier upgrades. Ensuring a steady supply of clean materials prevents bottlenecks when you attempt to unlock Strataform Events or late-game technologies.
Troubleshooting Common Issues
Even with careful planning, the physics-based nature of Sandustry can lead to unexpected factory behavior. The Spore Washer is prone to specific issues related to liquid pressure and solid blockages.
Q: Why is my Spore Washer outputting wet sludge instead of clean resources?
This usually happens when the water input pressure is too high, overwhelming the washing cycle. Install a **Valve** or reduce the pump speed to balance the liquid-to-solid ratio.
Q: My machine keeps jamming. What causes this?
Jams occur when large, non-processible objects (like heavy rocks) enter the intake. Ensure a **Filter** is placed on the input conveyor to remove debris before it reaches the Washer.
Q: How do I prevent water from flooding my factory floor?
Build a **Drainage Pit** or a dedicated runoff channel leading away from machinery. You can also use **Wall** blocks to contain potential spills within the processing module.
Q: Is the Spore Washer worth the energy cost?
Yes. Clean resources are significantly more valuable and unlock critical technologies. The energy cost is offset by the efficiency gained in automated production chains compared to manual cleaning.
