Moon Sweepers Vehicle Upgrade Guide: When to Tier Up
A transition-first guide to vehicle tuning: the five reported components and their priority, six signals you have outgrown a tier, and when to stop upgrading.
Last updated:
Upgrades are documented better than vehicles are
Nobody can publish a reliable vehicle roster yet. Launch-week guides describe three tiers with consistent prices but disagree on names, and at least one lists four completely different classes. Vehicle upgrades are in better shape: several independent write-ups describe the same component families and the same priority order. So this page covers tuning and transitions rather than a shopping list, and points you at the fleet reference for what is confirmed.
What a Tier Transition Actually Buys
Each step up the ladder changes the unit of work, not just the numbers. That is the fact worth planning around, and it holds no matter what the vehicles are called on your build.
| Tier | Reported entry cost | Unit of work | What it does not fix |
|---|---|---|---|
| Hand tools | Starting gear | A patch | Travel time |
| First motorized cleaner | Roughly $300, after a garage near $200 | A sector | Storage and selling throughput |
| Mid tier | Roughly $1,000 | A region | Base logistics |
| Top reported tier | Roughly $6,000 | A production feed | Nothing on the base side |
Each tier roughly triples in price, so justify a purchase by a change in how you play rather than by a stat bar. And no vehicle fixes a base problem: if storage fills faster than you can sell, a better vehicle only makes the failure arrive sooner.
The Five Components and Their Priority
Community write-ups describe vehicle tuning as a set of discrete components rather than a single upgrade level. The lists vary slightly, but the ranking converges:
| Priority | Component | What it changes | Buy it when |
|---|---|---|---|
| 1 | Big hopper | How much dust the vehicle carries | Immediately — it is capacity again |
| 2 | Tuned motors | Speed and acceleration under load | Once the hopper is comfortable |
| 3 | Cruise control | Holds a steady speed on long runs | Long straight routes between sector and station |
| 4 | Suction control | Intake width and pull rate | After motors, never before |
| 5 | Quick release | Unload speed at the collector | Several vehicles sharing one station |
The one counterintuitive entry is suction. A wider intake looks like free throughput, and it is not: it reportedly slows the vehicle, so buying it before motors can feel like a downgrade. The same warning appears in tuning guides for the base economy — rate upgrades multiply work you can already sustain, and they punish you when you cannot.
Suction also behaves differently from a passive stat. Multiple sources describe five discrete modes cycled while driving, from an eco setting up to full power, with higher settings pulling more dust and slowing you down. If your build works that way, the correct setting is a per-sector decision, not a one-time purchase. Leaving it on the wrong mode is invisible waste — the kind that makes a good vehicle feel mediocre.
Source strength on components
Big hopper and tuned motors appear in multiple launch-week guides. Cruise control and the five suction modes are described consistently by at least two. Quick release and the exact mode names come from single sources and should be treated as reportedly rather than confirmed. The priority order is community consensus, not official design documentation.
Six Signals You Have Outgrown the Tier
Upgrade until one of these is true. Then stop tuning and start saving, because tuning a vehicle you are about to replace is money you will not recover.
- You empty the hopper before the sector is half done. Capacity is the constraint, and a bigger hopper on the same chassis is the cheaper fix — for one tier.
- The sector ends but the trip does not. If working time is shorter than driving time, the tier's speed ceiling is the problem.
- You are skipping terrain. Slopes and rims you avoid are income you are declining. Handling parts help; a different class solves it.
- Two players are waiting on one vehicle. In co-op this is a fleet problem, not a tuning problem. See the multiplayer guide before someone buys a second one.
- Tuning costs more than the vehicle did. When the next component costs a fraction of the next tier's price, you are polishing a stepping stone.
- Your base is the bottleneck, not the dust. If storage or launching is the limit, no vehicle purchase helps and the money belongs in infrastructure.
Signals one and two are tuning problems. Signals three through six are transition problems, and the difference is worth several thousand credits.
What Upgrading Cannot Fix
Vehicle tuning is the most over-bought system in the game, because it is the most satisfying one. Three things it never repairs:
- A base that cannot absorb the inflow. Storage, conveyors, and launch cadence are separate purchases.
- A bad route. A tuned vehicle on a five-minute round trip loses to a stock vehicle on a two-minute one.
- A site you should have moved. The base scoring method exists because relocation beats tuning more often than players expect.
Upgrade or Buy the Next Class?
| Symptom | Cheaper fix | When to replace instead |
|---|---|---|
| Fill up too fast | Big hopper | When hopper tiers are exhausted and the sector still beats you |
| Too slow in transit | Tuned motors | When the route itself is the problem — move the station |
| Struggling on slopes | Handling components | When you avoid whole regions for terrain reasons |
| Slow unloading | Quick release | When three or more vehicles share one collector |
| Dust piling up at base | Nothing on the vehicle | Fix storage, conveyors, or launch frequency first |
Tuning is almost always the right first answer and almost never the right final one: buy components until the constraint moves, then follow it.
Budget Rules That Survive Patches
- One vehicle, one owner. Vehicles do not copy to crewmates, so a shared vehicle needs a named owner. Garages reportedly store and recall vehicles, which softens the loss when that owner logs off.
- Any garage should service any vehicle. A 1.0.3 patch reportedly allowed storing, retrieving, and upgrading through any garage. If your build predates that, keep the fleet at your main base.
- Do not buy a second vehicle before the first is tuned. A tuned hopper beats two stock vehicles, and the second only pays off once coverage, not capacity, is the limit.
- Confirm prices at the terminal. No dollar figure here carries a patch version. The garage screen is authoritative, and the progression guide puts vehicles in the wider purchase order.
What should I upgrade first on any vehicle?
The hopper. It is the same argument as containers on foot: capacity removes trips, and trips are the fixed cost this game charges for everything. Motors come second, and suction after that.
Is suction control worth buying early?
Usually not. It reportedly widens intake and slows the vehicle, so without tuned motors it can feel like a downgrade. Buy it once you have speed to spare, and set the mode deliberately per sector.
How do I know it is time for the next vehicle tier?
When tuning costs approach the next tier's price, when you are avoiding terrain rather than losing time on it, or when two players are competing for one machine. Those are transition signals, not tuning signals.
Do vehicle upgrades apply to my whole crew?
No. Vehicles and their components are personal purchases. Only matrix upgrades reportedly apply crew-wide, which is why the fleet reference recommends assigning one named owner per vehicle instead of pooling money loosely.
