In Sweep the Moon, the brush in your hand sets how much lunar regolith you clear on each pass, and that decides how fast your cash grows. Every brush is sold at the Tool Shop inside the base. They unlock in a fixed chain: each one needs the brush before it, and every step up makes your sweep wider.
Quick answer: Buy brushes in this order at the Tool Shop: Toothbrush (free), Scrubber, Dustpan Brush ($30), Broom ($50), Large Brush ($80), T-Bar Brush ($120). Each brush requires owning the one before it.
Sweep the Moon brush list: widths, prices and requirements
Each listing in the Tool Shop shows a short description, the head width in meters, how much wider it is than the brush you are holding, and a price. Locked brushes still show up in the list, along with a line telling you which brush to buy first.
| Brush | Width | Price | Requires |
|---|---|---|---|
| Toothbrush | 0.08 m | Free | Starting tool |
| Scrubber | 0.28 m | First purchase | None |
| Dustpan Brush | 0.39 m | $30 | None |
| Broom | 0.73 m | $50 | Dustpan Brush |
| Large Brush | Not listed | $80 | Broom |
| T-Bar Brush | Widest brush | $120 | Large Brush |
Toothbrush is the tool you start with. It is free and very narrow, so it only leaves thin lines through the dust. Once you upgrade, its shop entry changes to “Replaced.”
Scrubber is a block brush that you hold in your hand. The shop calls it your first real buy. At 0.28 m it is more than three times as wide as the Toothbrush, and you use it for most of the early dust runs.
Dustpan Brush features a compact grip with an extended head. With the Scrubber equipped, its shop entry shows a width advantage of +0.11 m over your current tool. Purchasing it immediately swaps out the Scrubber.
Broom is a full-length broom on a long stick. It is the biggest single jump in the chain. Going from the Dustpan Brush, it adds 0.34 m, which almost doubles your sweep width.
Large Brush is a braced push broom, and the shop says it clears a lane. T-Bar Brush is a wheeled sweeper with a T-handle and the widest brush in the shop. Buying the full chain after the Scrubber costs $280 in total.
How brushes sweep and fill your canister
Every brush works the same way. It goes into hotbar slot 1, and you hold the left mouse button to sweep. The prompt on screen reads “Hold to sweep.” The dust you pick up goes into your canister, which holds 6 kg at the start. A wider head clears more ground on each pass, so the canister fills faster and tiles finish in fewer strokes.
The CLEANED tracker in the upper right shows how much of the current tile you have cleared. It rises as you work across the cyan-outlined area. When it reaches 100%, the game shows “100% CLEAN!” and pays out a tile bonus.
Dust collects near walls, doorways and building seams as well as on open ground. Any spot inside the tile outline counts toward the tile’s percentage.
Earning cash for the next brush
Brushes cost cash, and you get cash two ways. You can sell dust at the Deposit station inside the base, or you can finish tiles. At the base payout of $1.00 per kg, a full 6 kg canister sells for $6.
| Source | Reward |
|---|---|
| Deposit a full 6 kg canister | +$6 |
| Clear a tile to 100% | +$4 to +$5, plus 3–4 Shards |
| Like the game and join the group | +2 kg canister |
Once the canister is full, the HUD shows “FULL! / 6 kg.” A pink waypoint then points you back to the base and shows the distance. Sweeping does nothing more until you empty the canister, so go back right away.
Inside the base, step onto the blue DEPOSIT pad. Floating text confirms the sale, for example “Deposit: 6.0 kg +$6,” and the canister empties. The podium next to it offers a free +2 kg of canister space if you like the game and join the group. That means fewer trips while you save up.
For a rough idea of the work, the Dustpan Brush costs five full canisters, and fewer if you finish a tile or two along the way. The Broom works out to about eight canisters’ worth of dust, and the T-Bar Brush to 20.
How to buy a brush at the Tool Shop
To check that the purchase went through, look at hotbar slot 1. It should now show the new brush’s name, and the tool in front of the camera should look different. The Dustpan Brush, for example, has a long white-and-yellow handle where the Scrubber was a small block.
Upgrade Computer stats that change your brush
The Tool Shop is not the only place to make your brush better. The Upgrade Computer in the UPGRADES room sells stat upgrades that apply to whichever brush you have equipped. Two of them affect the brush itself, and the others shorten the trips you make between brush purchases.
| Upgrade | Level shown | Change | Cost |
|---|---|---|---|
| Head width | 1 of 3 | 0.39 m → 0.43 m | $80 |
| Head power | 1 of 3 | 3.9 m/s → 4.5 m/s | $80 |
| Canister | 3 of 6 | 6 kg → 12 kg | $50 |
| Walk speed | 1 of 3 | 4.5 m/s → 4.9 m/s | $80 |
| Tile bonus | 1 of 2 | $4 → $8 per tile | $250 |
| Payout | 1 of 3 | $1.00 → $1.10 per kg | $300 |
Head width makes the brush head wider. With the Dustpan Brush equipped, the first level takes it from 0.39 m to 0.43 m. Head power makes the brush sweep faster. Both cost $80, which is more than the next Tool Shop brush at that stage. The $50 Broom almost doubles your width, while Head width adds a few centimeters.
The Canister upgrade costs $50, the same as the Broom. Doubling capacity to 12 kg halves your deposit trips, while the Broom clears more ground on each pass. You have to pick which one to buy first with that $50.
Saving for the Broom with the Dustpan Brush
After you own the Dustpan Brush, the Broom’s listing unlocks, and the cost is $50. You earn it the same way as before: sweep, fill the canister, sell at the Deposit station, and finish tiles for bonuses. The wider head makes the gaps along walls, under the building eaves and around the BELT IN conveyor chute quicker to clear.
The canister still holds 6 kg unless you have upgraded it, so you will still get full-canister warnings in the middle of a tile. The tile’s progress stays where you left it, and you can finish it after the deposit run.
Once you reach $50, go back to the Tool Shop pegboard and buy the Broom the same way you bought the Dustpan Brush. Each brush after that follows the same pattern. The Large Brush appears once you own the Broom, and the T-Bar Brush appears once you own the Large Brush.
A fully upgraded hand tool is still limited by the canister, so keep an eye on the Canister line at the Upgrade Computer as your brushes get wider. Each brush in the chain takes more cash than the one before, but it also fills the canister in fewer strokes, so the time between purchases stays reasonable all the way to the T-Bar Brush.
