Complete guide to the cleanliness system in inZOI covering cleaning tools, cooperative cleaning, the Housework skill with level unlocks, laundry system, furniture deterioration and refurbishing, hired cleaning services, the Hygiene need, autonomous cleaning with Smart Zoi, outfit categories, toddler messes, cleaning-related traits, City Sanitation settings, and cheats.
This article has been recognized for its exceptional quality and comprehensive coverage.
Overview
Cleanliness in inZOI affects both Zoi mood and household relationships. Dirty furniture, floors, and rugs accumulate grime over time, causing visual dirt and gameplay penalties. The Hygiene need depletes faster when the home is dirty, and wearing dirty clothing makes the Zoi Uncomfortable. Keeping the home clean requires manual effort, the right tools, or hired help.
Effects of Low Cleanliness
Effect
Details
Mood penalty
Dirty surroundings negatively affect Zoi mood, making them more likely to develop negative emotions.
Faster Hygiene drain
The Hygiene need depletes more quickly in a dirty environment.
Uncomfortable status
Wearing dirty clothes or living in a dirty home gives the Uncomfortable emotion. This escalates to Displeased if it accumulates, which further lowers Housework skill growth.
Relationship strain
Poor home cleanliness strains family relationships. Household members react negatively to living in filth.
Social isolation
Low Hygiene makes nearby Zois uncomfortable and can effectively isolate the household from social interactions.
Home Information Screen
The Home Information Screen displays the property's overall cleanliness meter and a count of dirty Zois in the household. Access it through the household management interface. The cleanliness meter provides a quick overview of how dirty the home is without needing to visually inspect every room.
Visual Indicators
Dirty furniture, floors, and rugs develop a marbled, dusty appearance. The grime is visible and gets progressively worse the longer cleaning is neglected. Dirty clothing on Zois shows visible dark grime, while clean clothes display full color and brightness.
Works both indoors and outdoors. The only tool for exterior cleaning.
Cordless Vacuum
35 Mew
5
More efficient than mop or broom. Recharges after use.
Premium Vacuum
450 Mew
5
The most efficient cleaning tool. Requires Housework Level 3 to use. Covers a larger area per action.
Cleaning tools do not permanently break or need repair. The "uses per session" count resets (tools recharge) between cleaning sessions.
Cleaning Efficiently
Cleaning floor sections is more efficient than cleaning individual furniture pieces. When you direct a Zoi to clean a floor section, nearby furniture on that section also gets cleaned. Bathroom fixtures (sinks, toilets, showers) are also cleaned automatically when you mop the bathroom floor; there is no separate scrubbing interaction for individual fixtures.
For larger cleaning jobs, use the multi-action commands:
Command
Effect
Clean 3
The Zoi autonomously cleans 3 dirty spots in sequence.
Clean 5
The Zoi autonomously cleans 5 dirty spots in sequence.
Clear Everything
Instantly clears everything from a selected table. Added in v0.2.0. Useful for dining table cleanup after meals.
Dirt Accumulation Rate
Dirt accumulates automatically over time regardless of usage frequency. At launch, the decay rate was extremely aggressive; players reported houses getting completely dirty within less than 12 hours of in-game time.
Patch v0.1.7 (April 2025) significantly slowed the rate at which lots become dirty. The developers acknowledged "the previous setting caused pollution to occur too frequently, disrupting the natural flow of gameplay."
The City Sanitation setting (under City Management > City Stability) affects the rate at which Zois and furniture become dirty. The slider has nine levels from Lowest to Highest, with higher settings supposedly increasing the rate at which things become clean. Results vary by player reports.
Furniture Deterioration and Refurbishing
Separate from regular dirt, furniture physically deteriorates over time. Sofas and beds develop visible tears, tables and counters show scuffs, and cabinets get worn-out finishes. Electronics like computers, TVs, washing machines, and stoves can break down entirely. Objects used more regularly deteriorate faster.
Action
Details
Refurbish
Requires Housework Level 2. Costs Meow. Restores furniture to original condition. Works on counters, cabinets, beds, and couches. Some chairs and tables cannot be refurbished and must be replaced.
Fix broken electronics (computers, TVs, stoves, washing machines) by selecting the item and choosing "Repair." Grants Housework skill XP. Alternatively, hire a Repair service for 100 Meow.
Warning: Broken electronics left unrepaired can cause fires. Address broken appliances promptly.
Hiring Cleaners
Two cleaning services are available through the Pocket Market app on the smartphone:
Service
Cost
Duration
Notes
Spick-And-Span
100 Mew
~1 hour
Basic cleaning service. Handles general cleaning and dirty dishes.
Good-As-New
500 Mew
~2 hours
Premium service. More thorough cleaning.
Important: When a cleaner arrives at the property, you must click on them and select the option to invite them in. Cleaners will not enter the house on their own. Forgetting this step means the cleaner stands outside and eventually leaves. These are one-time services with no recurring subscription option.
Laundry
Dirty clothes are handled through the laundry system. inZOI has nine outfit categories: Everyday, Formal, School, Sleepwear, Party, Sportswear, Swimwear, Summer, and Winter. Each category currently supports only one outfit slot.
Detail
Description
Equipment
A washing machine is required. Place one via Build Mode in the Bathroom furniture category.
How to wash
Click the washing machine and select "Wash Laundry." The process completes in seconds. A second option, "Wash with Natural Detergent," is available to Zois with the Coexistence value.
Age restriction
Only Adults and Teenagers can do laundry independently. Children must use "Ask to Do Laundry" to request a nearby adult. The laundry area needs space for two Zois to stand together near the machine.
Automation
Laundry can be set as a preference in the Zoi Card interface, which makes the Zoi prioritize doing laundry autonomously when dirty clothes accumulate.
No dryer
The game has no clothes dryer. There is no loading/unloading cycle, folding animation, or visible laundry progression stages.
The Hygiene Need
Hygiene is one of four physical needs (alongside Hunger, Sleep, and Bathroom). Low Hygiene does not kill a Zoi, but it makes nearby Zois uncomfortable and can effectively isolate the household.
Action
Hygiene Restored
Shower or bath
Best method. Fills the gauge substantially.
Washing hands at a sink
Fills approximately half the hygiene bar. Takes only a few seconds.
Brushing teeth
Minor hygiene boost.
Washing face at a faucet
Minor hygiene boost.
Fabric freshener / disinfecting bedding
Minor relief from the Uncomfortable emotion.
The Perfectionist trait causes the Hygiene gauge to decrease more quickly, meaning those Zois need more frequent grooming.
Housework Skill
Cleaning contributes to the Housework skill. Higher levels make cleaning faster and more thorough. The skill can be raised through cleaning with any tool, doing laundry, repairing broken electronics, refurbishing furniture, crafting custom furniture at a Furniture Workbench, and performing cleaning tasks at active jobs (Deli, Burger Shop).
Level
Unlock
Level 2
Ability to Refurbish deteriorated furniture.
Level 3
Premium Cordless Vacuum Cleaner (450 Meow). The most efficient cleaning tool.
Level 7
Prestige Front Load Washing Machine. Superior to the basic washing machine.
Level 10
Maximum level. Required for the Neat Freak ambition (Level 3).
The Uncomfortable emotion slows Housework skill growth, and when it escalates to Displeased, it further hinders growth. Address mood issues (hunger, sleep, hygiene) before attempting cleaning sessions.
Neat Freak Ambition
The Neat Freakambition (under Stay Healthy) tracks cleaning milestones across three levels:
Prioritizes orderliness and routine. Hygiene gauge decreases more quickly, requiring more frequent grooming.
Slacker (v0.4.0)
Zois with this characteristic have a chance to refrain from cleaning up empty plates or books.
Players can also set cleaning as a preference under Zoi Card > Preferences (yellow heart on cleaning and laundry). With Autonomy enabled, the Zoi will clean automatically whenever the opportunity arises.
Writing personality descriptions like "you are a clean freak" in the Smart Zoi prompt demonstrably increases autonomous cleaning behavior, even without changing formal preferences.
Toddlers and Messes
Toddlers generate significant mess: diapers, bottles, trash, and papers knocked from bookcases. A major bug in earlier versions caused Zois to not autonomously clean up toddler-generated messes, leaving houses full of debris. This was fixed in v0.4.4 (November 2025). Toddlers also trigger frequent "Clean Up" requests in the Zoi queue.
Outdoor Cleaning
Outdoor areas (lawns and exterior spaces) also accumulate dirt and contribute to the overall lot cleanliness rating. The broom is the tool intended for outdoor use, though a known quirk causes Zois and hired cleaners to occasionally vacuum the lawn instead. The community views this as a design quirk that may be refined in future updates.
Stops the property from getting dirty. Furniture and floors stay clean indefinitely.
instantClean
Immediately cleans all furniture and surfaces on the entire property.

Tips
Buy a Cordless Vacuum (35 Meow) as soon as possible. It cleans 5 spots per session versus 3 for the mop/broom. Upgrade to the Premium Vacuum at Housework Level 3.
Clean floor sections rather than individual furniture. It covers more area per action, and bathroom fixtures are cleaned automatically when you mop the floor.
Use Clean 3 or Clean 5 multi-actions to automate cleaning runs without manual direction for each spot.
Set cleaning as a preference on one adult Zoi (Zoi Card > Preferences > yellow heart on cleaning and laundry) so dirty areas get handled automatically with Autonomy enabled.
Buy a broom early for outdoor cleaning. It is the only tool that works outside.
Level Housework to 3 as soon as possible to unlock the Premium Vacuum. It is expensive (450 Meow) but covers more area and is significantly more efficient.
Repair broken appliances yourself instead of hiring a technician (100 Meow). It saves money and grants Housework XP.
Feed your Zoi and let them rest before cleaning sessions. The Uncomfortable emotion slows Housework skill growth.
Watch the Home Information Screen periodically. It gives a snapshot of how dirty the house is before the visual grime becomes obvious.
If money is tight, the Spick-And-Span service at 100 Meow is affordable and handles the basics. Remember to click the cleaner to invite them inside.
