Cleaner Company Online Co-op Guide (1–4 Players)

Cleaner Company is built for online co-op with up to four Star Wipers and remains fun solo when the squad is offline. Wildflame Studio and Mythwright lean hard into party drama: blackouts, comms malfunctions, gambling team earnings, and friends who spill more than they scrub. This guide turns that mayhem into a repeatable plan—roles, callouts, zoning, and threat discipline—so your Flying Canteen demo runs (and future 2026 contracts on Steam and Epic) end in profit instead of a second murder scene.

If you are brand new, pair this page with Getting Started. For a concrete map, use the Demo walkthrough. For creature fights, open Survive threats.

Co-op fantasy in one sentence

Choose calm cooperation or absolute mayhem—officially, you can profit from either—as long as the facility eventually shines.

Pre-drop checklist for squads

1. Confirm platform party — Steam or Epic group ready; check system requirements so one potato PC is not the soft wipe.
2. Align difficulty — Decide monsters on or off before launch. Untoggling threats is allowed and great for teaching tools.
3. Assign primary roles — See the matrix below. Flex is fine; zero assignment is not.
4. Agree on staging — One “dump and regroup” room that is not the final showcase floor.
5. Share binds mentally — Someone always forgets the vacuum key. Point them at Controls.
6. Pick a shot-caller — Not a dictator—just the person who resolves “two mops, zero guns” arguments in five seconds.

Role matrix that actually works

Role	Primary tools	Owns	Avoids
Wetwork	Mop, powerwasher	Liquids, stains, finish passes	Random grenading of clean floors
Extraction	Cosmic vacuum, trash grinders	Solids, debris, body chunks	Leaving piles in finished rooms
Security	Guns, flamethrower	Creatures, escorting cleaners	Celebratory full-auto in polished halls
Logistics / flex	Whatever the gap is	Objectives, doors, relocating props, chicken herding	Standing AFK in the pretty window bay

In a duo, merge Wetwork+Extraction and Security+Flex. In a trio, keep a dedicated Security if monsters are on. Solo players rotate the same hats—see Getting Started for the solo mindset.

Gear identity is expanded on Cleaning equipment and ranked on the Equipment tier list.

Zoning rules (stop cleaning the same tile)

• Split by rooms, not by tool fetish. “I only mop” is fine if your room still needs mopping; it is toxic if the kitchen is drowning.
• Finish solids before polish in a zone whenever possible.
• After a fight, the Security player either helps re-clean or stands guard while Wetwork repairs the blast art.
• Call “zone closed” when a room is inspector-ready so nobody “helps” with a splashy tool.

Callout vocabulary

Keep it short:

• “Slime on me—kitchen.”
• “Hold wash—chickens inbound.”
• “Staging overflow; need grinder.”
• “Blackout—group on wetwork.”
• “Zone closed: dining.”
• “Re-clean after shots: view deck.”

Comms malfunctions and blackouts are part of the fantasy. When the game breaks your chatter, fall back to visual roles: Security watches ears, Wetwork stays on stain color, Extraction keeps moving piles.

Mayhem mode vs calm mode

Calm cooperation — Monsters off or low threat, strict zones, inspector sweep at the end. Best for learning Flying Canteen and teaching new Star Wipers.

Absolute mayhem — Monsters on, optional gambling energy, intentional chaos—but still designate who cleans the aftermath. Mayhem without a cleanup owner is just a failed contract with funny clips.

Both are valid. Company policy, per the pitch, lets you profit from either if the job completes.

Threat discipline in a four-stack

• Do not stack four guns in a closet while the dining floor floods.
• Security peels threats away from finished zones when possible.
• Flamethrower is glorious and filthy—budget re-mop time.
• If the squad is learning, untoggle monsters and read Survive threats before the hard toggle-on night.

Facility-specific co-op notes

• Flying Canteen (demo) — Dense restaurant geometry; easy to double-work booths. Chickens are mobile chaos. Walkthrough: Demo walkthrough.
• Experimental Laboratory (playtest) — Containment and specimen logic; Security matters more. See Locations.
• Polar Facility (playtest) — Cold pressures pacing; do not strand the mop main across the map. Same locations page.

Track what returns in the 2026 release via Updates and Demo & playtest notes.

Social contract (seriously)

• Do not dump trash in a closed zone “as a joke” unless everyone opted into mayhem mode.
• Revive / regroup plans beat flaming your friend for tipping a bucket—unless that is the bit and the clock still allows a fix.
• Rotate prestige jobs (final inspector, flamethrower) so one player is not forever bucket guy unless they love bucket guy.

Practice plan for new squads

1. One monsters-off Canteen clear with strict roles.
2. Same clear with roles rotated.
3. Monsters-on clear with a dedicated Security.
4. Review tool gaps on the Tools hub and Tier list hub.
5. Bookmark Guides hub, Links, and Wiki for the next patch.

Online co-op is Cleaner Company’s heart: equal parts PowerWash fantasy, slapstick physics, and “why is there a Screamer in the walk-in freezer.” Assign roles, call zones, and leave the stars shining—or at least less sticky.
