Sweep The Moon Co-op Guide

Sweep The Moon is an incremental cleaning simulator where the official pitch is clear: sweep dust tile by tile, empty your canister for cash, upgrade tools, then bring vehicles and robots online until the moon hits 100% clean. DomBlox Games also advertises cleaning with up to four friends, and that co-op layer changes how you spend cash, place docks, and drive shared bays. This guide is the deep playbook for crews—invite flow, role split, vehicle and dock sharing, Moon Marshal value, tile division, and how Head Start interacts with a busy bay.

How co-op fits the core loop

Every player still runs the same basic cycle: brush dust into a canister, dump at base for cash, buy upgrades, unlock vehicles and automation. Co-op does not delete that loop; it multiplies throughput. Four canisters emptying on a schedule keep cash flowing. Four brushes on neighboring tiles finish Shard-paying clears faster. One player can shop or belt-build while others sweep. Dock robots clean for the whole crew, so automation purchased by any member raises group output.

Servers may list a larger max player count, but treat four friends as the design target. Form the party with Roblox invites into one host session so you share the same moon state, the same vehicle bays, and the same dock network. Agree on a short goal before loading: finish three tiles, unlock the first dock, or park a sweeper. Vague sessions turn into four people wandering half-clean patches with empty Shard gains.

Shared vehicle bays

Vehicle bays are crew infrastructure. A sweeper or giant rover sitting in a bay can be driven by friends cleaning that moon. That means vehicle cash is a shared investment: buying a chassis helps whoever is on driving duty this minute. Keep at least one bay strategy:

1. Announce before purchasing so you do not lock the last empty bay by accident.
2. Rotate drivers on longer routes so hand-sweepers are not stuck without a vehicle all session.
3. Separate the vehicle budget from brush and canister upgrades early—do not starve the Dustpan Brush / 6KG canister path just to park a toy rover.

For chassis choices and pass interactions, use the vehicles guide. Pair driving with the Driver class when someone lucks into that 1% spin: crew vehicle speed and canister bonuses stack nicely with shared bays.

Head Start pass on a crew moon

Head Start costs 199 Robux and places a fully paid walk-behind sweeper in the first empty bay once per moon. The vehicle is shared—your friends can drive it. If every bay is already occupied, the pass supplies no vehicle that moon. Crew checklist before someone relies on Head Start:

• Leave one bay empty on purpose until the pass fires.
• Do not fill bays with impulse buys right as the host (or pass owner) joins.
• Decide who drives the free sweeper while others clear tiles for the first robot dock footprint.
• Remember the pass is permanent across moons, including a friend’s moon, so ownership can sit with any crewmate.

Head Start is a timing tool, not a substitute for cash planning. After the free sweeper appears, keep upgrading brushes and canisters so dump income still scales when someone steps out of the vehicle.

Robot docks clean for the crew

Robot docks are the other shared pillar. Place a dock on cleaned ground, then belt the robot’s Dust Out toward the base Belt In. Robots from that dock clean for everyone on the moon. The +1 Robot Dock pass (149 Robux) lets the owner place one small dock for free each moon, relocate it after pickup, and use it on a friend’s moon as well. That makes the pass a crew gift: one buyer can seed automation on every moon the party visits.

Build order tip for co-op:

1. Manually finish at least one tile so a dock has legal placement space.
2. Drop a affordable dock before sprawling belts.
3. Connect Dust Out → Belt → Base Belt In; leave dump pad access clear.
4. Only then expand splitters and longer conveyor runs.

Full belt and dock detail lives in robots and automation. Mechanic (0.5% class) boosts crew robot and machine speed—pair that roll with dock owners when possible.

Dividing tiles without dogpiling

Finished tiles pay better than messy partial sweeps. Community guidance consistently favors clearing tiles fully (auto-complete around the high-nineties percent) for cash bonuses and roughly 3–4 Shards per finish. In co-op, assign neighboring tiles instead of stacking four avatars on one square:

• Player A and B take adjacent tiles near base for short dump walks.
• Player C drives the shared sweeper on a longer strip.
• Player D places or tends the first dock and belt spine.

Call outs when a tile is nearly done so nobody steals the last percent without meaning to. Partial cleaning earns zero Shards, so a loud hour of random scrubbing can still be a Shard drought. Short sessions of three finished tiles beat long sessions of unfinished dust.

Moon Marshal aura and other crew classes

Classes come from 50 Shard spins in the lobby Classes shop. Odds are heavily skewed: Strider is common, Moon Marshal is 0.01%. Moon Marshal carries the bonuses of other classes plus a crew aura that pays everyone on the moon 10% more. When someone rolls Marshal:

• Keep the whole party on that moon while the aura matters.
• Prioritize finished tiles and dump uptime over exploratory wandering.
• Let Marshal (or Chief Engineer at 0.1%) call spend priorities if the crew agrees.

Driver and Mechanic are the next co-op-relevant rolls. Surveyor and Pocket Seller help personal cash; Brushwright discounts tool shop spending for the buyer. Full odds and rankings: class tier list. Shards are lobby-bound long-term currency—farm them by finishing tiles even during co-op nights.

Role templates for a four-friend crew

Opener crew (first hour together): two hand-sweepers on base-adjacent tiles, one dump runner, one upgrade buyer watching brush and canister tiers.

Vehicle crew: one dedicated driver on the shared bay, two tile finishers, one builder preparing dock space.

Automation crew: one belt specialist, one dock placer/relocator, two sweepers feeding Shards and cash so the factory is not starved.

Swap roles every fifteen minutes so nobody burns out on dump walks. Use the tools hub session plan template if you want a written checklist before invite.

Passes that change co-op math

Optional Robux passes are permanent and work on friends’ moons. High-impact crew notes:

• +1 Robot Dock (149): free small dock per moon for the owner; robots help everyone.
• Head Start (199): shared free sweeper if a bay is empty.
• Fast Vehicles (149): +30% speed for vehicles you drive—still useful when you take a turn at the wheel.
• 2x Cash (249) and Sell As You Sweep (249): personal income multipliers that keep you funding shared upgrades.
• Everything (649): bundle of the main passes—compare against the two or three you actually need.

Never treat passes as required. Free play reaches vehicles and robots through cash; passes only compress time. Check codes when DomBlox drops strings—none confirmed in November 2026 checks—then keep grinding tiles.

Common co-op mistakes

• Filling every bay before Head Start can fire.
• Building belts that block the dump pad.
• Dogpiling one tile while three neighbors stay untouched.
• Spending all cash on vehicles before Dustpan Brush and a larger canister.
• Ignoring Shard finishes, then wondering why nobody can afford class spins.
• Rearranging a friend’s belts without asking.

Avoid those, and four friends will outpace four solos on the same moon. Link back to the Players Hub for etiquette, upgrades for spend order, and the guides above for vehicles and robots. Clean tiles, share bays, seed docks, and push toward 100% clean together.
