- Clean the Moon moon percentage measures how much lunar debris you have cleared overall.
- Every resource counts: moon dust, space junk, and meteor debris all contribute to progress.
- Backpack and broom upgrades raise your cleaning rate more than raw walking speed early on.
- Cleaning robots keep the percentage climbing while you are offline or exploring new craters.
- Track zone-by-zone: each crater's contribution adds up to the total moon percentage.
What the Clean the Moon Moon Percentage Represents
The Clean the Moon moon percentage is the game's core progress tracker. Every pile of moon dust, piece of space junk, and meteor fragment you sweep up pushes the overall lunar cleanliness score higher. Developer Lunarlit Works built the game around this loop: clean debris, collect materials, sell them for cash, and reinvest in brooms, backpacks, moon boots, cleaning robots, and a growing lunar base.
The percentage works on multiple levels:
| Progress Layer | What It Measures | How to Increase It |
|---|---|---|
| Total moon percentage | Overall lunar debris cleared across all zones | Clean steadily in any unlocked area |
| Zone contribution | Debris cleared within a single crater | Focus one zone before moving on |
| Automation share | Passive cleanup from cleaning robots | Unlock robots and expand the lunar base |
| Sell-and-upgrade efficiency | Cash reinvested into cleaning power | Buy the upgrade that fixes your bottleneck |
If your percentage growth slows down, it is almost always a bottleneck problem: a full backpack forces sell trips, a weak broom slows clearing, or slow travel wastes time between debris fields. Fix the biggest delay first.
How Each Resource Type Affects Your Percentage
Not all debris contributes equally. Understanding the value of each resource type helps you choose routes that push the percentage up fastest.
| Resource Type | Where to Find | Percentage Impact | Best Route Style |
|---|---|---|---|
| Moon dust | Starting lunar area | Low per unit, very fast to collect | Short loops near the sell point |
| Space junk | Starting area and first crater | Medium value, moderate clearing time | Lane routes with multiple sources |
| Meteor debris | Later craters | High value, slower to clear | Longer runs with upgraded capacity |
Moon Dust Farming
- Dependable early game income
- Short routes, minimal travel
- Ideal for first-hour progress
Space Junk Runs
- Balanced value and speed
- Several debris sources per lane
- Upgrade backpack when trips interrupt
Meteor Debris Runs
- Highest contribution per run
- Needs stronger broom and capacity
- Best once equipment is mid-tier
Do not abandon an efficient nearby route too early. Longer routes can slow percentage growth if travel and clearing time outweigh the extra debris value. Stay local until your gear supports longer cycles.
Step-by-Step: Raising Your Moon Percentage Fast
Follow this proven progression order to convert every cleaning session into maximum percentage gains.
Clear Nearby Debris First
Use your starter broom on debris close to the spawn area. Learn the clean-collect-sell loop without overextending into distant zones.
Sell Before Your Backpack Overloads
Watch capacity and return to the selling point while you can still finish a route. Interrupted runs waste collection time and slow percentage growth.
Buy the Upgrade That Removes Your Bottleneck
Backpack capacity if sell trips are too frequent, broom power if clearing is slow, moon boots if travel dominates your time.
Push Into the First Crater Prepared
Save enough currency for both the zone access cost and one immediate gear upgrade so the new area is worth entering.
Add Robots and Expand the Base
Once manual cleaning is stable, invest in cleaning robots and the lunar base so the percentage keeps rising automatically.
Speed and capacity upgrades first, first robot second, base expansion third. Return to equipment upgrades whenever manual cleaning becomes the main bottleneck again.
Automation: Keeping the Percentage Climbing
Cleaning robots and the lunar base turn active cleaning into steady passive progress. Automation complements manual play rather than replacing essential upgrades.
| Automation Stage | When to Invest | Main Benefit |
|---|---|---|
| First cleaning robot | After core broom and backpack upgrades | Passive resource flow between sessions |
| Additional robots | When the base supports them without delaying gear | Scaled automated collection |
| Lunar base expansion | When base limits reduce efficiency | Storage and automation platform |
| Base decorative upgrades | Last, after efficiency is secured | Comfort, not percentage speed |
Never spend on base expansion if it delays the gear needed for the next zone. A stable manual loop funding upgrades plus a modest robot lineup beats an overbuilt base with underpowered equipment.
Percentage Push Checklist
Session Goals for Faster Progress:
- Complete three full collect-and-sell cycles without interruption
- Identify your current bottleneck: capacity, speed, or travel
- Purchase one bottleneck-fixing upgrade per session
- Keep at least one cleaning robot active in a cleared zone
- Prepare currency for the next crater unlock before moving
Split the crater into sections with friends, assign collection roles by backpack capacity, and coordinate base returns. Divided lanes mean less duplicated work and a faster-rising moon percentage for everyone.
Moon Percentage FAQ
Q: What is the Clean the Moon moon percentage based on?
It tracks how much lunar debris you have cleared overall. Moon dust, space junk, and meteor debris across every unlocked crater all contribute, with higher-value resources in later zones boosting it faster.
Q: Does cleaning with robots count toward the percentage?
Yes. Cleaning robots generate passive or semi-passive resource collection, which supports ongoing progress while you manually clear new areas or are away from the game.
Q: Why did my percentage growth slow down?
Usually a bottleneck: a backpack that fills too quickly, a broom that clears debris too slowly, or travel time that outweighs collection value. Buy the upgrade that removes your biggest delay first.
Q: Should I rush to unlock the next crater?
No. Save enough currency for both the zone access cost and one immediate gear upgrade. Entering a new crater underprepared often earns less per minute than an efficient route in your current zone.
