Everything you buy with cash in Sweep The Moon comes from one machine: the Upgrade computer in the lunar base hub. It holds 20 upgrade levels across six branches. Each level is a small, fixed bump to one stat, so it pays to know what each one does before you spend anything.
Quick answer: Open the Upgrade computer inside the base and buy levels in Canister, Head width, Head power, Walk speed, Payout or Tile bonus. Early levels cost $50 to $300.
Sweep The Moon upgrade list and prices
The Upgrade computer groups its 20 levels into six branches. A counter on the screen tracks how many you own out of 20. A fresh moon starts at 2/20 owned, with the Canister branch already sitting at Level 3 of 6. Each card shows the current value, an arrow, and the value you get after buying.
| Upgrade level | Levels in branch | Stat change | Cost |
|---|---|---|---|
| Canister Level 3 | 6 | 6 kg ▶ 12 kg | $50 |
| Head width Level 1 | 3 | 0.39 m ▶ 0.43 m | $80 |
| Head power Level 1 | 3 | 3.9 m/s ▶ 4.5 m/s | $80 |
| Head power Level 2 | 3 | 4.5 m/s ▶ 5.1 m/s | $200 |
| Walk speed Level 1 | 3 | 4.5 m/s ▶ 4.9 m/s | $80 |
| Payout Level 1 | 3 | $1.00 ▶ $1.10 per kg | $300 |
| Payout Level 2 | 3 | $1.10 ▶ $1.20 per kg | $800 |
| Tile bonus Level 1 | 2 | $4 ▶ $8 per tile | $250 |
The six branches each fix a different problem in the sweeping loop:
- Canister raises how much dust you carry, which means fewer walks back to the deposit.
- Head width makes the brush head wider, so each stroke covers more ground.
- Head power makes the brush sweep faster.
- Walk speed raises your movement speed on foot.
- Payout raises the cash you get for every kilogram you sell.
- Tile bonus raises the cash paid each time you fully clean a tile.
Levels inside a branch unlock in order. The Payout Level 2 card stays locked with the message Buy level 1 first until you own the first level. Prices climb fast within a branch. Head power jumps from $80 to $200 between its first two levels, and Payout goes from $300 to $800.
How cash reaches the Upgrade computer
Upgrades only take cash, and cash comes from two places: tiles you finish and dust you sell. Both start the same way. Equip the Dustpan Brush from slot 1 and hold the button shown by the Hold to sweep prompt while you aim at dusty ground.
Tile completion pays instantly
The ground is split into tiles marked by glowing white grid lines, and a blue box shows the tile you are working on. A percentage tracks how clean that tile is. Push it to 100% and the game shows 100% CLEAN!, then pays a cash bonus and a handful of Shards on the spot. Completed tiles pay around $4 to $5 and 3 to 4 Shards at the starting Tile bonus level. You do not need to walk back to the base to collect this money.
Selling dust at the Deposit station
Swept dust fills your canister, and the counter reads up from 0.00 / 6 kg. When it hits the cap, it switches to FULL! / 6 kg. A red Canister full waypoint then appears with a distance in meters, pointing back to the Deposit station inside the base. The brush picks up nothing more until you empty the canister.
Follow the waypoint through the airlock and stand at the Deposit station. A full starter canister sells as Deposit: 6.0 kg +$6, because the base Payout rate is $1.00 per kg. That figure is the reason the first Canister and Payout levels matter so much later on.
Buying an upgrade at the Upgrade computer
UPGRADES. It is the Upgrade computer, and it sits inside the base near the entry hall. You do not need to swap off the Dustpan Brush to use it.
You need $17 more, and the number shrinks as your balance grows.Bought: Head power appears, and the owned counter ticks up by one, for example from 2/20 owned to 3/20 owned. The new stat applies as soon as you head back out. After the first Head power level, the brush sweeps at 4.5 m/s instead of 3.9 m/s.Which Sweep The Moon upgrade to buy first
The prices on the Upgrade computer make the early order fairly clear once you compare what each level gives back.
Canister Level 3 is the cheapest level on the board at $50, and it doubles capacity from 6 kg to 12 kg. That halves the number of trips to the Deposit station for the same amount of dust. No other early level changes the loop that much for that little cash.
Head power, Head width and Walk speed all cost $80 for their first level. Head power and Head width both shorten the time a tile takes, which means faster tile bonuses. Walk speed only helps on the trip between the dust and the base. That walk gets shorter in relative terms once your canister is bigger, so Walk speed fits better after the other two.
Payout and Tile bonus are slower investments. Payout Level 1 costs $300 and adds $0.10 per kg. At that rate it takes 3,000 kg of sold dust to earn the $300 back. Tile bonus Level 1 costs $250 and adds $4 to every finished tile, so it pays for itself after roughly 63 tiles. Because tiles pay more per completion than a full starter canister sells for, Tile bonus is the better of the two income upgrades early on.
Other ways to change canister and income limits
A few options outside the Upgrade computer change the same stats, and some of them cost Robux instead of cash.
| Option | Effect | Price |
|---|---|---|
| Join the group prompt | +2 kg canister | Free |
| INFINITE CANISTER | Canister and vehicles never fill | 99 Robux, or 29 Robux for one moon |
| SELL AS YOU SWEEP | Dust pays as you sweep | 249 Robux |
| Walk-behind sweeper | First vehicle for a bay | $400 cash |
The in-game prompt for the free bonus reads LIKE THE GAME JOIN THE GROUP +2 kg CANISTER. You can join the DomBlox Games community on Roblox to claim it. The Infinite Canister store prompt offers two versions: a permanent one and a cheaper THIS MOON ONLY version.
The Walk-behind sweeper is the next major cash goal once you’ve finished the first round of upgrades. Beyond the base are four vehicle slots, labeled BAY 1 through BAY 4; each displays Next: Walk-behind sweeper $400. Hold the interact prompt to put cash toward the purchase, and the sign will show the amount still needed. Cash added to a bay can’t be used for the Upgrade computer, so choose one goal and pay it off before dividing your money between them.
