Clean the Moon Upgrade Guide (Roblox)

Every upgrade in Clean the Moon! on Roblox is paid for with cash from moon dust. You sweep the dust, sell it at the Lunar Converter, and spend the money in the Upgrades menu. The menu is split into four tabs. Each one changes a different part of the loop, and the prices are low enough that a single full load can usually pay for one or two of them.

Quick answer: Fill your bin, park in the green sell zone at the Lunar Converter, then open Upgrades (the button shows a Tab key hint). Buy from the General, Tool, Bag, or Vehicles tab.

Clean the Moon – Upgrade Guide

Earning cash for upgrades with the Junk Hauler

Upgrades cost cash, and cash only comes from selling what you clean. The Junk Hauler is a cleaning vehicle that scrapes layers of dust off the surface and pulls loose ores into an onboard bin as it drives. It also picks up crystals and candy along the way. The loop below runs the same way whether you are on foot with a broom or behind the wheel. The vehicle simply carries more per trip.

Drive the Junk Hauler across dusty ground near the base. Each pass strips dust layers from the tiles under its brush, and the “MOON CLEANED” meter at the top of the screen tracks how much of the map you have cleared so far.

Keep sweeping until the bin counter reaches its cap. The base Junk Hauler bin holds 500 units. At 500/500 the game shows “Capacity full!” and the vehicle stops collecting, so there is nothing to gain by driving further out.

Turn around and follow the glowing cyan chevron arrows on the ground. They appear when the bin is full and point you straight back to the base outpost.

Park inside the green circular sell zone by the Lunar Converter. The load unloads into the machine, which turns each piece of dust into cash over time rather than all at once.

Because the Converter processes dust at a fixed rate per item, your cash total keeps climbing for a few moments after you park. The Convert Time upgrade shortens that wait.

Clean the Moon upgrade costs and stats by tab

The Upgrades menu has four tabs: GENERAL, TOOL, BAG, and VEHICLES. Each row shows the stat’s current value, what it becomes after the purchase, and the price. The price listed is always for the next level only, and it goes up after you buy. Boots, for example, cost $2.00 for one level and $6.00 for the one after it.

General tab

General upgrades apply to you and your base rather than to a specific tool. They stay useful no matter which broom, bag, or vehicle you are using at the moment.

Upgrade	Effect	Change	Cost
Boots	Walk speed	20 → 24	$2.00
Boots	Walk speed	24 → 29	$6.00
Sell Value	Your sales pay more	+25% → +60%	$6.75
Luck	Rare ores in the dust	+50% → +100%	$4.00
Conveyor Speed	Belt speed	3 → 5 studs/s	$9.00
Convert Time	Time per dust	0.3s → 0.25s	$1.25

Sell Value is a straight multiplier on every sale, so it pays back on each load you bring in. Luck raises how often rare ores show up in the dust you sweep. Convert Time is the cheapest row on the tab and cuts how long the Lunar Converter spends on each item. At level 5 the Converter handles one item every 0.25 seconds. Conveyor Speed only matters once you own conveyors. Each of the four conveyor slots around the base (North-West, South-West, South, and East) costs $60.00, and buying one is an early quest objective.

Tool tab (Push Broom)

The Tool tab upgrades the broom you sweep with on foot, which is the Push Broom here. All three rows change how much ground each swing clears.

Upgrade	Effect	Change	Cost
Stroke Speed	Time between strokes	0.6s → 0.48s	$4.00
Sweep Width	Tiles per stroke	5 → 7	$3.75
Power	Layers per stroke	3 → 4	$11.00

Stroke Speed makes you swing more often, Sweep Width makes each swing cover more tiles, and Power strips more dust layers per swing. Power is the priciest of the three, but it means fewer passes over the same tile before it is clean.

Bag tab (Bucket)

The Bag tab has a single stat for the Bucket, Extra Capacity, which raises how much dust you can carry on foot before a trip back to the Converter. Two levels in a row cost $2.00 (144 → 163) and then $3.00 (163 → 188). That makes it one of the cheapest ways to cut down on walking.

Vehicles tab (Junk Hauler)

The Vehicles tab has the most rows, and every one of them applies to the Junk Hauler.

Upgrade	Effect	Change	Cost
Drive Speed	Speed	24 → 26	$3.00
Brush Size	Brush width	1.5 → 1.75 tiles	$4.50
Power	Layers per pass	1 → 2	$14.00
Bin Size	Bin holds	500 → 600	$3.00
Battery	Drive time	190s → 238s	$1.00
Battery	Drive time	238s → 285s	$2.50

Battery is the cheapest upgrade in the whole menu. Its first level adds 48 seconds of driving for a dollar. Bin Size adds 100 units to every load, so each trip to the Converter is worth more. Power doubles the layers the Hauler removes per pass, from one to two, and it is the most expensive row shown at this stage. Drive Speed and Brush Size shave time off each run by moving you faster and widening the strip you clear.

How to buy an upgrade and confirm it applied

Open the Upgrades menu once your cash has settled after a sale. The UPGRADES button shows a Tab key hint. The Lunar Converter also has its own [E] UPGRADE prompt when you stand next to it.

Pick the tab for the gear you want to improve. GENERAL covers you and the base, TOOL covers your broom, BAG covers your bucket, and VEHICLES covers the Junk Hauler.

Click the price button on the row you want. The cost comes out of your cash right away, and the row moves to the next level with a new, higher price.

You know it worked because a confirmation appears on screen naming the new value. Examples are “Bucket extra capacity upgraded to 163!” and “Junk Hauler battery upgraded to 238s!” The row also updates. A Boots upgrade, for instance, then shows the next level as “24 > 29” at $6.00. Some upgrades note their level directly, such as “Boots level 3” or “Lunar Converter level 5.”

Recharging the Junk Hauler battery

The Junk Hauler drains its battery the whole time you drive, and the Battery upgrade only extends how long a full charge lasts. It does not refill the vehicle. Upgrading after a long run usually leaves you with a low battery, so check the meter before heading back out.

Drive onto the white-and-yellow charging pad at the base and stay parked. The screen reads “CHARGING JUNK HAULER” while the percentage climbs, then switches to “FULLY CHARGED JUNK HAULER” at 100%. A charge from 21% to full takes a noticeable stretch of time, so it is a good moment to look over the Upgrades menu.

Once it is full, drive back out to fresh dust. Any upgrades you bought, such as a larger bin or longer battery, apply from the next run onward.

Goblin Raids during a cleaning run

A Goblin Raid can interrupt your upgrade loop. A 10-second countdown appears alongside the alert “GOBLIN RAID INCOMING FROM EVERY SIDE”. Next, the game instructs you to take your ray gun and defend the Outpost.

A short cutscene follows, showing green goblins landing with the message “Goblins are coming for the base!” You can skip it, and you can leave the vehicle with F. During the raid, an objective counter tracks the goblins (32/32 at the start) alongside a timer. The game also confirms “Moon saved! Your progress is kept if you leave,” so the cash and upgrades you have earned are safe if you step away.

Once the raid is dealt with, the routine is unchanged. Fill the bin, sell at the Lunar Converter, buy the next upgrade, and top up the battery before the following run.
