The Sims 4 Fabulously Filthy Aspiration
Is your sim disgusting? Maybe they should play the sims 4 fabulously filthy aspiration!
This aspiration comes with The Sims 4: Bust The Dust which comes with a whole filth system.
You’ll need to focus on making your sims house as dirty as possible, by being gross!
Home Turf Bonus Trait
When you start your sim with any of the location aspirations they are going to be given the home turf trait. This means that the sim is happier when they are spending time in their own neighbourhood, giving them a positive moodlet at home.

Best Traits for The Sims 4 Fabulously Filthy Aspiration
Usually I have a whole list of traits to give a sim that can be helpful in an aspiration, but this aspiration is so specific that there is truly only one.
You must give your sim the Slob trait. The trait’s description says “These sims are not affected by dirty surrounds, make household items dirtier faster, and can rummage for food in garbage.”
Everything about that will make this aspiration easier! Your house will be so disgusting but your sim will be totally okay with it.
Stages of the Aspiration
There are four stages of this aspiration for your sim to work through, each more disgusting than the last. As you finish tasks your sim will get satisfaction points to spend in the reward store!
Stage One: Procrastinator

- Leave Out Food to Spoil 3 Times
The first thing you need to do in the sims 4 fabulously filthy aspiration is leave out food to spoil 3 times. To do this, you’ll need to get your sim to cook a meal. You can cook a group meal and then get your sim to grab a serving three times and cancel the interaction when they start eating so you can cook one meal to satisfy this!

Your sim will leave the meal on the table or counter and you’ll be able to hover over it and see how long until it is spoiled. Leave it there until it spoils to satisfy this requirement!
- Let 3 Kitchen or Bathroom Objects Get Dirty
The next task is to be gross and let plumbing or appliances get dirty. The items that are included in this are things like:
- Counters
- Sinks
- Toilets
- Showers
- Bathtubs
- Stoves

To do this you can let it happen naturally but that will take time. You can click on the item and use it over and over to make it dirty (but it might break) or you can use cheats by holding down shift and clicking on the item and choosing make dirty.
- Let at Least One Floor Level of Your Home Become Dirty
There is a ranking system for dust in the game that goes from Clean to Dusty to Dirty to Filthy. For this your sim will need to get to dirty. All you need to do is avoid cleaning up any dust piles or vacuuming for a few days! You can click on the ground and choose check dust level to see how far you’ve gotten.
- Max Out Your Sim’s Fun Motive While on a Dusty, Dirty or Filthy Floor
When you click on the check dust level button and see anything other than clean you’re set to do this task.

All you need to do is fill your sim’s fun need by doing anything. You can watch TV, play video games, play an instrument, literally anything that brings up the fun need!
Stage Two: Chore Dodger

- Successfully Ask 3 Sims to Clean
There are two ways you can ask others to clean for you, the first way is to click on them and look for the ask for help cleaning option. I couldn’t find this in any of the more choices menus, I only ever saw it in the initial menu!

The other option is to click on the floor in your home and when another sim is present you can click ask for help cleaning and a menu will appear where you can pick a sim and they can help you.

- Befriend a Dust Bunny
When your house gets dusty you’ll eventually start seeing dust bunnies appear on the ground. These precious little guys can be pretty useful actually, if you’re friends! To start you’ll want to feed the dust bunny dust whenever you can, there is a cooldown so you will have to wait a while between feedings.

You’ll start with a neutral happiness dust bunny but you want to get them to high so you can start petting them. Then feed them dust and pet them over and over (both have cooldowns though) until you get them to be very high and the befriend option is available.

You can then click befriend and your sim will pick them up and give them a snuggle. This means that the dust bunny won’t disappear even if your sim vacuumed their entire house!

- Cook 3 Meals on a Dirty of Filthy Floor Level
When you click on check dust level and it says dirty or filthy you’re set to start cooking! Why would you want to cook in a dirty house? Who knows! But this one is easy, then just leave these out to spoil because your sim needs to eat spoiled food later.

- Pay for a Cleaning Service
The fact that this is in the fabulously filthy aspiration makes 0 sense. We want to be dirty! What you need to do here is go in the home menu on your sim’s phone and choose hire a service.

Then, choose a one time maid. Once it satisfies the need, go to the maid that comes over and click on them and choose dismiss so they don’t clean the whole house and make your lose your dust progress.
Stage Three: Low Standards

- Eat 3 Meals That Are Spoiled
When you make a meal you’ll see a quality ranking and a timer when you hover over it. You’ll need to let the food get to the spoiled level and then get your sim to grab a serving and eat it.

Sims who are slobs or gluttons can do this without getting sick, but other sims will probably throw up!
- Bathe or Shower 3 Times in a Dirty Shower or Tub
This is my nightmare. For this you’ll first need to have a dirty shower or bath tub in your sim’s house. Then, get them t o either take shower or take bath (any of the versions) while it’s dirty!

Pro Tip: If you don’t want to wait for it to get dirty you can cheat it! Make sure cheats are turned on and then shift + click on the item and chose make dirty.
- Don’t Wash Your Hands After Using The Toilet
Gross. Sims who have the slob trait will do this automatically every single time. However, if you have a sim without that trait you can get them to use the toilet and then have an interaction queued up after so they go do that instead of washing their hands. You can also cancel a wash hands interaction that they might do on their own.
- Invite a Guest Over While House is Dirty or Filthy
Once you can click and check dust level and see dirty, it’s time to invite over another sim. You’ll want to click on them in your social menu and invite over to current lot and it should satisfy this need.

Stage Four: Filth Fiend

- Knock Over 3 Trash Cans
To be able to kick over a trash can your sim first needs to be angry! You’ll need them to have an angry moodlet which you can get from a bunch of different ways:
- Negative Interactions With Other Sims
- Viewing Angry Paintings
- Be Cheated On
- Hot-Headed Trait
- Being Around Good Sims When Evil
Once your sim is angry you can go to a trash can and choose the kick option to knock it over. You can then pick it up and kick it again and then pick it up and kick it again to finish this!

- Throw a Party Social Event in a Filthy House
When you can check dust level and you get the filthy response back, you are ready to go to throw a party.

Go to the social menu on your sim’s phone and choose plan social event and then choose any of the party options in the start an event menu.

You’ll satisfy this need when the party is complete!
- Appease a Filth Fiend with a Filth Tribute
When your house eventually becomes filthy dust bunnies won’t appear anymore. The filth fiend will come instead! You’ll need to click on one of these and choose appease. It may not work on the first time, you need to get their happiness up a bit and do it multiple times.

- Woohoo in Filthy House
I’m not entirely sure how sims can get excited and want to woohoo when the house is this gross, but okay! When you check your dust level and it says filthy, bring over someone who you have a romantic relationship with.

Then, click on a bed, shower, or whatever other woohoo location inside the house and woohoo with them! Imagine if you chose a sim who did the perfectly pristine aspiration and loves to be clean, I’d feel so bad for them.
Filth Dweller Reward Trait
When your sim manages to finish the sims 4 fabulously filthy aspiration they will be given the filth dweller reward trait.

This trait’s description says “This sim no longer receives negative moodlets from living in dusty or messy environments. They loathe cleaning and love filth and will receive happy moodlets when in dirty or filthy houses. Additionally, they gain the ability to bond with and befriend filth fiends.”
These sims are just gross, and that’s hilarious!
