Moon Sweepers: How Long to Beat and 100% the Moon
A stage-by-stage read on completion time, built from Steam achievement distribution and player reports, with a method for measuring your own remaining grind.
Last updated:
There is no ending, so there is no clean hour count
Moon Sweepers does not roll credits. You start with a toothbrush on a Moon covered in dust, and the only finish line is the one achievement stats track: clean 100% of the lunar surface. That makes "how long to beat" a question about scope rather than story. Steam achievement data gives us real progress checkpoints; nobody has published a verified total, and we are not going to invent one. What we can do is show you the stages, the evidence behind each, and how to time your own run.
What Counts as Beating It
There are three defensible answers, depending on what you want from the game.
| Goal | What it requires | Who it is for |
|---|---|---|
| "I've seen the game" | First vehicle, first automated belt, a few regions cleaned | Most players, first session or two |
| "I've finished the content" | All machines, all vehicles, a self-running base | Players who like factory games |
| "I've beaten it" | 100% of the Moon cleaned | Completionists with a lot of patience |
Only the third has a hard definition, tracked by the achievement Time To Go Sleep..., which requires the overall Moon percentage to reach 100%. Everything below it is a judgment call. The achievements guide covers all 33 unlocks individually; this page is only about the clock.
The Scale Problem
Before any estimate, you need to feel the size of the map. The Moon is divided into hex sectors, and one player's Moon Map reportedly showed more than 163,000 total sectors while sitting at 0.09% completion after substantial cleaning around the starting area. Both figures come from a single session and are reported, not published — but they match how the game feels, which is that your first hour barely moves the global number.
Steam's global achievement percentages, checked two days after launch, fill in the shape of the curve:
| Milestone | Share of players |
|---|---|
| Collect 100 kg of dust | 87.8% |
| Build a first conveyor to a depot | 75.3% |
| Collect 1,000 kg of dust | 62.1% |
| Get a first vehicle | 57.9% |
| Play with a friend | 50.1% |
| Earn $10,000 | 28.4% |
| Earn $100,000 | 8.5% |
| First Moon-clean milestone | 5.0% |
| Earn $1,000,000 | 0.4% |
Read that as a funnel, not a timeline. Half of all players had not built a belt to a depot within 48 hours, which says more about how people sample a $8.99 game than about difficulty. The bottom row matters most: 0.4% earning a million dollars means the deep economy is a minority pursuit, and 100% moon completion will sit far below even that.
Stage-by-Stage Estimates
These are estimates, assembled from achievement distribution, player write-ups, and the known cost curve of the progression. They are not measurements, and the ranges are wide because a 16-player lobby and a solo player are playing different games.
| Stage | Ends when | Estimate | Basis |
|---|---|---|---|
| First hour | Toothbrush → household broom → first deposit | 45–90 minutes | Player reports of early loops; $25 broom is reachable fast |
| Tool escape | Wide broom, capacity upgrades, first region finished | 2–4 hours | Reported early-session accounts |
| Vehicle era | Garage plus a working rover | 4–8 hours | $200 garage plus a $300+ vehicle, at early payouts |
| Automation | Belt to depot, packager, first pressure chamber | 8–15 hours | Machine costs of $500–$1,000 against mid-game income |
| 1% of the Moon | First completion achievement | 15–30 hours | Extrapolated from sector counts and reported progress |
| 10% of the Moon | Visible From Space | 60–120 hours | Extrapolation; no verified runs |
| 100% of the Moon | Time To Go Sleep... | 300+ hours, or never | Extrapolation from sector count and automation throughput |
The jump between 1% and 10% is where most players stop, and it is not a difficulty wall. It is a scale wall. The automation you build in the first ten hours is what makes the next hundred possible, which is why the progression guide treats the factory as the real mid-game rather than an optional side system.
Why the last row is honest rather than precise
Nobody has published a verified 100% run, and the game is five days old. Anyone quoting a firm "X hours to finish" is working from the same extrapolation we are, minus the label. Treat 300+ as "very long, possibly not worth it" rather than a schedule.
Estimate Your Own Remaining Time
The most useful number is not ours. It is the one you measure in your own save, and it takes ten minutes.
- Note your completion percentage from the Moon Map, with the real-world time.
- Play a normal session of 30 to 60 minutes — not a speedrun, not a test.
- Check the map again. The delta is your real rate, including every belt repair.
- Divide the remaining percentage by that rate.
A player moving 0.05% per hour needs roughly 2,000 hours to reach 100%. A player with a fully automated J.O.N.A.S. network moving 0.5% per hour needs 200. The difference is not skill; it is whether dust is being collected while you do something else, which is what the auto-sell setup and the zone map exist to enable.
Run the measurement twice. The first session usually includes more building and less cleaning than normal, which makes your rate look worse than it is.
Why Multiplayer Changes the Math
A 16-player lobby does not divide the time by sixteen, but it changes what the hours are for.
Shared money and, since patch 1.0.3, a shared upgrade matrix mean a coordinated crew compounds faster than the same people alone. Ground gets cleared in parallel, and belts get built once instead of four times. The multiplayer guide covers the role split; the timing consequence is that a group can reach automation in a single long evening.
It cuts the other way for a disorganized lobby. Sixteen players each buying their own tools and building their own belts is slower than four players with a plan, because the shared bank account funds everyone's experiments. Those hours go into undoing each other's layouts, and the moving buildings page explains why undoing is expensive.
The Honest Bottom Line
Moon Sweepers is a two-to-four-hour game if you stop when the loop stops feeling new, a fifteen-hour game if you want the factory tier, and a very long game if you want the 100% achievement. All three are legitimate. The game does not gate credits behind the last one, because there are no credits.
If you are deciding whether to start, that is worth knowing up front: this is a game you finish by deciding you are done. The beginner guide gets you to where that decision is meaningful, and the achievements guide shows what the long tail contains.
How long does it take to beat Moon Sweepers?
There is no story campaign and no credits, so there is no official completion time. Reaching a self-running base takes most players somewhere in the 8 to 15 hour range; cleaning 100% of the Moon is a 300+ hour extrapolation that nobody has verified.
How many hours is the main content?
If "main content" means tools, vehicles, and a working automation line, plan on roughly ten to fifteen hours. The systems keep expanding after that, but the game stops introducing new ones and starts asking you to scale.
Is 100% Moon completion realistic solo?
Rarely. The map reportedly holds over 163,000 sectors, and solo throughput is limited by how fast one player can sweep and sell. A 16-player crew with automation is the realistic route to the top of the achievement list.
Does co-op reduce the time to finish?
Yes, but not proportionally. Shared money and shared upgrades since 1.0.3 make a coordinated crew much faster at reaching automation, while an uncoordinated lobby can be slower than solo because everyone funds their own layout.
How do I know how much is left?
Open the Moon Map and read the overall completion percentage, then measure your rate across two normal sessions. Remaining percentage divided by your hourly rate is a more honest estimate than any number on this page.
