Moon Sweepers Calculator: Free Factory Ratio, Power and 7x Payback Planner
The Moon Sweepers calculator works out the factory ratio for Moonstone: how many Pressure Chambers feed your Stone Presses, how much Moon Dust the line eats each minute, how much power it draws, and how long the machines take to pay for themselves.
Raw Moon Dust is the weakest thing you can sell. Moon Sand sells for 3 times as much and Moonstone for 7 times as much, so the sooner your dust goes through a balanced line, the faster every later upgrade arrives.

How the Moon Sweepers Calculator Works
A Stone Press takes 1 kg of Moon Dust and 1 kg of Moon Sand and makes 2 kg of Moonstone every 6 seconds. That is 10 kg of each input and 20 kg of Moonstone per minute. A Pressure Chamber turns up to 5 kg of Dust into Moon Sand every 12 seconds, or 25 kg per minute. The Moon Sweepers calculator divides one by the other, so one Pressure Chamber feeds two and a half Stone Presses.

- Enter the Pressure Chambers and Solar Posts you own.
- Enter the Moon Dust your crew and robots bring in per minute.
- Enter the price your game pays for 1 kg of raw Dust.
- Read what to build next and how fast the line pays for itself.

Brooms and Vehicles: What to Buy and What to Skip
| Tool or vehicle | Price | Width or note | Capacity |
|---|---|---|---|
| Toothbrush | Free | 12 cm | 0.5 kg |
| Nail Brush | $5 | 18 cm | 0.75 kg |
| Hand Brush | $10 | 24 cm | 1 kg |
| Household Broom | $25 | 43 cm | 3 kg (6 kg with the $30 container upgrade) |
| Wide Broom | $75 | 65 cm | 6 kg |
| Extra Wide Broom | $150 | 98.8 cm | 12 kg |
| Push Sweeper | $300 | First vehicle | Not published |
| Ride-on Sweeper | $1,000 | Big Hopper upgrades to 950 kg | 500 kg |
| Lunar Sweeper | $2,500 | Vehicle | Not published |
| Mega Vacuum Rover | $6,000 | Vehicle | Not published |
The Nail Brush and Hand Brush are cheap but small steps. The Household Broom at $25 nearly doubles the Hand Brush width and triples its capacity, so many players go straight to it. Early upgrades worth the money are Wide Heads ($40 for 8% more width), Rapid Transfer ($30) and Market Contracts ($120 for 6% higher launch payouts).
Moon Sweepers Calculator Worked Example
You want three Stone Presses. They need 30 kg of Moon Sand per minute, so the Moon Sweepers calculator asks for two Pressure Chambers. The line draws 74 kW, which is 25 Solar Posts, and eats 60 kg of Dust per minute. It costs $5,875 to build. At $1 per kg of raw Dust the line earns $420 per minute as Moonstone, against $60 raw, so it pays for itself in about 16 minutes.
Tips for a Better Moon Sweepers Factory
- Build power first. A machine without enough kW stops, and Solar Posts lose output at night.
- Keep the ratio at 2 Pressure Chambers for every 5 Stone Presses.
- Robot Vacuum Mk II covers 37 hexes for $500, almost double the Mk I for double the price. Skip Mk I if you can wait.
- Lunar Exchange costs $2,500 and needs Market Contracts level 3, so plan for it once the presses run.
- Run the Moon Sweepers calculator again when your Dust income changes, because Dust supply is the usual bottleneck.
About Moon Sweepers
Moon Sweepers is a co-op incremental game about cleaning the Moon. You start with a toothbrush, sweep Moon Dust off hexagonal tiles, pack it into capsules and launch it for cash. It released on Steam in late October 2026 and sold more than 700,000 copies in its first weeks.
The game moves from hand tools to vehicles such as the Ride-on Sweeper and Mega Vacuum Rover, then to automation with Robot Vacuums, Conveyors, Splitters, Mergers and the JONAS robot. Upgrades are shared across the crew in multiplayer.
