Can I pour another soap into a Xiaomi dispenser? full guide to fluid replacement

Xiaomi’s automatic liquid soap dispensers (e.g., Mijia Smart Liquid Dispenser or Viomi models) S9) They've become a popular solution for bathrooms and kitchens, which save money, dose portions, and even sync with a smartphone, but what if the original soap is out of place and it's expensive or inconvenient to buy branded cartridges? Can you pour in the device ordinary liquid soap, shower gel or disinfectant solution – and how to do it without risk to the technique?

In this article, we will explore all the nuances of fluid replacement in Xiaomi dispensers, from choosing compatible products to step-by-step instructions for pouring. You will learn which formulations are strictly prohibited (and why), how to properly flush the tank and avoid typical errors leading to clogging of the mechanism.

What soap can be poured into the Xiaomi dispenser: selection criteria

Not every liquid soap is suitable for automatic dispensers.

• 🧼 Consistency: the liquid should be thin (viscosity not higher than 500 mPa·s.
• 💧 Absence of abrasives: particles (scrabs, salt) scratch the internal parts and disable the dispenser.
• 🧪 Neutral pH: optimally 5.5-7. Acid or alkaline agents corrode plastic and rubber seals.
• 🌿 Without oils and silicones: these components leave the film on the sensors and disrupt the sensors.

Suitable options:

• 🧴 Liquid soap without dyes and fragrances (for example, Dove, Sanex Zero%).
• 🧼 Alcohol-based antibacterial gels (up to 60% alcohol).
• 🧽 Handwashing products marked “for dispensers” (Ecover, Frosch).

⚠️ Note: Do not use shower gels with moisturizers (lanolin, glycerol) – they crystallize in tubes and block the supply.

If you doubt the composition, check it for compatibility with plastic: apply a drop on the inside of the dispenser cover and leave for 10 minutes. If the plastic is not cloudy and not deformed, the product is safe.

Step-by-step: how to pour other soap into the dispenser

Before replacing the liquid, be sure to wash the tank to remove the residues of the old remedy and avoid chemical reactions.

Turn off the device from power (if the model with the socket)

Remove the remnants of old soap (tilt the dispenser over the sink)

Wash the tank with warm water (without detergents!)

Dry all the details with a paper towel.-->

1. Dismantling and cleaning

Remove the top cover of the dispenser (usually fixed by latches or threads). S9 And the Mijia Smart tank is taken out completely -- pull it up with a little effort:

• 🚰 Reservoir: fill with warm water (40–50)°C, shake and drain. Repeat 2-3 times.
• 🔧 Nozzle: Clean with a needle or toothpick if deposits are noticeable.
• 🔄 Pump: pump clean water through it (in models with manual pumping).

2.Pouring new soap

Fill the tank to the edges — leave 10-15 mm of free space to avoid overflowing when the pump is running.

1. Pour the soap into the tank through the funnel (comes complete or use a homemade paper).
2. Set the tank back, making sure it sat tightly in place (there should be a click).
3. Connect the power and run the test release of a portion of soap (click on the sensor or button).
4. If the portion is too large/small, adjust the dosage in the Mi Home app (Settings section). → Dosage).

⚠️ Note: In models with infrared sensors (e.g. Viomi) S9) Do not touch the sensor with wet hands – this will cause false positives.

💡

If the soap thickens when stored, dilute it with distilled water (1:1) and mix. Don't use tap water - chlorine and salts form a precipitate.

What happens if you pour the wrong tool?

Ignoring the soap recommendations leads to breakdowns that are not covered by the warranty.

• 🔧 Pump clog: thick gels or particulate agents block the mechanism. Symptoms - the dispenser "buzzes" but does not give out soap.
• 💧 Leaks: Aggressive compounds (such as chlorine) corrode the O-rings.
• 📱 Sensor failures: oils and silicones form a film on the IR sensor, which is why the device does not respond to the hands.
• 🔋 Contact corrosion: salts in hard water or soap oxidize metal parts.

Average cost of repairing a dispenser after using the wrong soap:

If the dispenser stopped working after replacing the soap, try resetting the settings:

1. Turn off the power supply for 10 minutes.
2. Hold the 15-second switch (for models with a mechanical button).
3. Connect the power and perform calibration in the Mi Home app.

Top.-5 Alternatives to the original soap for Xiaomi dispenser

We tested popular tools for compatibility with Xiaomi Viomi dispensers S9 And Mijia Smart. The rating is based on the criteria: viscosity, foaming, effect on the mechanism and price.

For models with automatic dosing (for example, Viomi) S9) You should choose products marked "for dispensers" - they are optimized for pumping systems. If you want to save money, dilute the thick soap with distilled water in a ratio of 1: 1.

💡

The safest solution is a liquid soap with neutral pH and low viscosity, and even if it's more expensive, it's a lot more expensive to repair the dispenser.

How to make homemade soap for Xiaomi dispenser

If you don't trust the products you buy, you can make a safe solution yourself.

• 🧼 Baby soap (without fragrances, such as Ear-eared nanny).
• 💧 Distilled water (sold in pharmacies or car stores).
• 🧪 Glycerin (optional, to soften the skin).

Recipe:

1. Grate 30g of baby soap on the grate.
2. Dissolve the shavings in 200 ml of hot distilled water by stirring.
3. Add 1 tsp of glycerol (optional) and stir.
4. Cool the solution to room temperature and strain through the gauze.
5. Share the distilled water to a volume of 500 ml.

Store homemade soap in a glass container for no longer than 2 weeks. Before pouring into the dispenser, check the viscosity: the solution should flow freely from the pipette.

⚠️ Do not use household soap – its pH exceeds 9, which destroys the plastic dispenser.

Frequent Mistakes and How to Avoid Them

Even experienced users make mistakes when replacing soaps.

• 🚫 They don't flush the tank before pouring the new soap, and the residues of the old soap can react with the new soap to form flakes.
• 🚫 Soap is poured above the maximum level, and this leads to leaks and failures of the level sensor.
• 🚫 They use tap water to dilute, and chlorine and salts are deposited at the pump.
• 🚫 They close the lid loosely, and as a result, the soap dries and thickens.

How to avoid problems:

Wash the tank every 2 weeks

Use only distilled water for dilution.

Keep the dispenser away from direct sunlight

Check the tightness of the cover after each refill-->

If the dispenser starts to dosage soap incorrectly (for example, it gives too much or little), calibrate:

1. Open the Mi Home app.
2. Select your dispenser in the list of devices.
3. Go to Settings. → Dosage calibration.
4. Follow the instructions on the screen (usually press the sensor 3 times in a row).
