The game

What Is Moon Sweepers?

Moon Sweepers is a first-person co-op cleaning simulation about restoring the lunar surface with a toothbrush, a crew, and eventually a small industrial base.

Developer: DragDrop Games
Released: 23 Oct 2026
Platform: Windows / Steam

What it is

The premise is a joke told completely straight. The Lunar Surface Department has an entire Moon to clean and a budget that covers one toothbrush. You are the crew sent to do it. The game never winks at you about this — it simply hands you a brush and a very large dusty surface.

Under the joke is a progression game with three distinct phases: manual cleaning with hand tools, vehicle-based clearing, and factory automation. Each phase makes the previous one feel deliberately primitive.

The tone is what makes the grind feel relaxed rather than punishing.Official Steam screenshot, copyright DragDrop Games. Used for identification and commentary.

The core loop

Sweep dust, pack it into a capsule, carry it to a depot, launch a shipment, and spend the money on better equipment. That is the whole game for the first hour, and it stays the whole game later — machines just perform the middle steps without you.

Six repeating steps. The only thing that changes across the game is who performs steps two through five.

Three materials, one chain

Dust is not simply sold. It can be processed into Moon Sand at three times the value, and combined with more dust into Moonstone at seven times. Both conversions cost power rather than money, which makes power generation an income upgrade in disguise.

The value chain. Each step needs a machine, a power budget, and a working belt route to the depot.

How progression escalates

The game has a fairly clear four-stage structure, and knowing it helps you avoid spending money on the wrong stage.

The four stages of Moon Sweepers progression
Stage	Tool	Money comes from	New problem
Opening	Toothbrush to Household Broom	Manual dust plus hex bonuses	Walking distance
Manual mid	Wide and Extra Wide Brooms	Dust volume and region bonuses	Container capacity
Vehicle	Push Sweeper to Mega Vacuum Rover	Large loads cleaned fast	Unloading and transport
Automation	Robot Vacuums and J.O.O.N.A.S.	Processed material, unattended	Power and bottlenecks

The transitions are not gates — you can buy a vehicle before the Extra Wide Broom, or a Pressure Chamber before a vehicle. But the problems each stage introduces are what the next stage solves, and buying out of order usually means paying for a solution to a problem you do not have yet.

TipThe most common progression mistake

Buying a processing machine before transport works. A Pressure Chamber multiplies the value of dust that reaches the depot. If your dust is not reaching the depot, the multiplier applies to nothing.

Co-op and solo

Moon Sweepers supports single-player and online co-op for up to 16 players. Money is shared, and since patch 1.0.3 upgrades are shared too. There is no split-screen and no crossplay.

Sixteen is an unusual number for this genre, and it changes the game in a specific way: large crews stop being about cleaning faster and start being about logistics. Someone has to keep the belts running while everyone else drives around.

Tone and pacing

The game is tagged Relaxing, Comedy and Job Simulator on Steam, and that combination is accurate. There is no combat, no fail state, and no timer. The pressure is entirely self-imposed: you want the next upgrade, and the next upgrade costs more than you have.

The pacing does have a rough patch. The first twenty minutes are slow by design — the toothbrush holds almost nothing, and trips to the depot dominate. Players who judge it in that window tend to bounce. Players who reach the Household Broom usually stay.

NoteA fair warning about launch state

The game launched on 23 October 2026 and received two substantial patches in two days, after the developers publicly acknowledged crashes, performance problems and progression balance issues. If you are reading this much later, check the patch history for the current state rather than relying on launch-week reviews.

Who it is for

You will probably like it if you enjoy visible progress, tidying games, factory chains, or playing a low-stakes co-op game while talking with friends.

You will probably bounce if you want combat, narrative, or a game that respects your time from minute one. The opening is deliberately silly-slow, and the 100% completion goal is measured in hundreds of hours.

Watch it in motion

Trailers for this game are honest about the loop and quiet about the grind, which is the usual arrangement. Watch the official one for tone, then a longer creator session for the pacing.
