Xiaomi’s automatic soap dispensers are not just a fashionable gadget, they’re a real simplification of everyday life. They save cleaning products, maintain hygiene (no contact with the bottle) and often integrate into the Mi Home ecosystem. But even with such a simple device, there are nuances: improper refueling can lead to leaks, clogs or breakage of the pump. In this article, we’ll look at all the steps from choosing soap to fixing typical problems.
It's important to understand that the Mi Automatic Soap Dispenser, the Mijia Smart Soap Dispenser and the Redmi models have different tank designs and feed mechanisms, for example, some versions have a fluid level sensor that gets lost when you use thick gels, and we'll take these features into account and give recommendations for each modification.
What soap is suitable for Xiaomi soaps: selection criteria
Not every detergent is compatible with automatic dispensers.
- 🧼 Consistency: liquid or gel-like, but not too thick (viscosity not higher than 500 mPa·s.
- 💧 Without abrasives: particles (scrabs, salt) scratch the internal parts and disable the pump.
- 🌿 pH neutral: aggressive alkalis (pH) > (9) corrodes the plastic of the reservoir.
- 🚫 Alcohol-free: ethanol evaporates and leaves sticky sediment on sensors.
The best options are:
- 🧴 Liquid soap marked "for dispensers" (e.g. Dove, Palmolive).
- 🧼 Antibacterial gels without triclosan (it crystallizes when drying).
- 👶 Children's products with hypoallergenic composition (suitable for models with the function "Baby Mode").
In Xiaomi soapboxes with a UV lamp, you can not use perfumes based on citrus oils - they are oxidized under ultraviolet light and form toxic compounds.

Step-by-step: how to pour soap into the tank
The refueling process is the same for most models, but there are nuances for touch-controlled devices (e.g. Mijia Smart Soap Dispenser). 1S) And you can use the Mi Automatic Soap Dispenser Lite:
- Turn off the power (take out the batteries or disconnect). USB-This will prevent accidental activation of the pump.
- Remove the top cover: 🔄 In models with magnetic fastening pull the lid up. 🔧 In threaded versions (such as Redmi Smart Soap Dispenser) turn counterclockwise.
Remove the tank.
Rinse the container
Pour the liquid in.

For models with a level sensor (for example, Xiaomi Mi Smart Soap Dispenser Pro): after refueling, press and hold the power button for 5 seconds to calibrate the sensor.
Common Mistakes and How to Avoid Them
Even experienced users sometimes have problems after refueling, and consider the most common:
| Mistake. | Reason. | Decision |
|---|---|---|
| No soap is served. | Tube clog or air traffic jam | Blow the tube with your mouth (from the nozzle side) or rinse with water. |
| Leak from under the lid | The tank is not tightly closed or the sealing ring is damaged. | Close the lid, check the ring for cracks |
| The dispenser gives out too much/little soap | Incorrect viscosity of the means or failure of calibration | Dilute the soap with water (1:1) or recalibrate the pump |
| A foreign smell | Use of soap with essential oils or liquid stagnation | Wash the tank with vinegar solution (1:10) and dry |
⚠️ Warning: If the soapbox starts to make squeaky sounds after refueling, this is a sign of overloading the pump. Turn off the device immediately and reduce the amount of soap in the tank to 70% of the maximum amount of soap in the tank.
In models with infrared sensors (for example, Mijia Smart Soap Dispenser) T1) Leakage may occur due to soap hitting the sensor. Wipe it with a cotton swab dipped in alcohol (no more than 70%!).
What if the soapbox stopped working after filling?
How to Dilute a Thick Soap for Xiaomi Soap
Many users find that their favorite soap is too thick for an automatic dispenser. Dilution is the way out, but it is important to do it correctly so as not to spoil the consistency and not to reduce the detergent properties.
Optimal proportions:
- 💦 Shower gels: 2 parts soap + 1 part distilled water.
- 🧴 Cream soap: 1 part soap + 1 part water + 0.5 part glycerol (to maintain viscosity).
- 🧼 Toilet soap (grunted): 1 tbsp. spoon of chips + 100 ml of hot water, stir until dissolved.
Dilution instructions:
- Heat the water to 30-40.°C (hot water destroys surfactants).
- Add water to the soap in small portions, stirring constantly with a plastic spatula (the metal is oxidized).
- Let the mixture settle for 1-2 hours. If there are flakes, strain through the gauze.
- Check the viscosity: drop on an inclined surface - the soap should drain in a slow trickle.
⚠️ Warning: Do not use tap water to dilute -- chlorine and hardness salts cause sediment to form in the tubes. Only distilled or boiled water!
💡
To flavor a homemade soap solution, add 2-3 drops of lavender or tea tree essential oil (they have antibacterial properties and are not oxidized in plastic).
Maintenance of soap: cleaning and disinfection
To last longer, the dispenser must be cleaned regularly, depending on the intensity of use:
- 🏠 Home Use (1–2 times daily): Cleaning 1 time per month.
- 🏢 Public places (office, cafe): cleaning every 2 weeks.
Step-by-step cleaning:
- Pour the residues of soap and rinse the tank with warm water.
- Pour a solution of vinegar (1:10) or 0.5% chlorhexidine into the tank for 10 minutes.
- Pass the cleaning solution through the pump (press the issue button 2-3 times).
- Wash the system with distilled water (3-4 cycles of issuing).
- Dry all the details in the air (do not use a hair dryer!).
For models with a UV lamp (for example, Xiaomi Mi Smart Soap Dispenser) UV): After cleaning, turn on the lamp for 30 minutes to disinfect the interior surfaces. Don't look at the UV lamp that's working, it's dangerous for your eyes!
💡
Using 3% hydrogen peroxide to disinfect the tank kills 99.9% of bacteria, but can damage plastic with frequent use (no more than 1 time in 3 months).
Compatibility with Xiaomi models: Characteristics table
Not all Xiaomi soaps are the same, with different tank size, power type and detergents supported. Below is a summary table for popular models:
| Model | Volume of the reservoir | Type of food | Supported viscosity | Features |
|---|---|---|---|---|
| Mi Automatic Soap Dispenser | 250 ml | 4×AA battery | up to 300 mPa·s | Mechanical button, no level sensor |
| Mijia Smart Soap Dispenser 1S | 300 ml | USB-C | up to 500 mPa·s | Touch management, integration with Mi Home |
| Redmi Smart Soap Dispenser | 280 ml | 3×AAA battery | up to 400 mPa·s | Budget version, without UV lamp |
| Xiaomi Mi Smart Soap Dispenser Pro | 350 ml | USB-C + battery | up to 600 mPa·s | UV lamp, level sensor, voice control |
For voice-controlled models (via XiaoAI) after refueling, you may need to reconnect to the Mi Home app.
- Open the app and select the device.
- Go to Settings. → Reconnect.
- Follow the instructions on the screen (usually hold the button on the dispenser for 3 seconds).
Alternative ways to use Xiaomi soapbox
In addition to standard use, the dispenser can be adapted for other tasks:
- 🧴 Lotion dispenser: suitable for liquid creams without oils (for example, Nivea Soft.
- 🍯 Automatic honey distributor: pour liquid honey (pre-heat in a water bath to 40).°C).
- 🎨 For artistic paints: acrylic or gouache paints diluted with water (1:1).
- 🐶 Pet shampoo dispenser: Use hypoallergenic products with a pH of 5.5-7.
Important: For foods (honey, syrups), separate the soap bowl and wash it thoroughly after each use. In plastic tank models, it is not recommended to store acidic liquids (for example, lemon syrup) for longer than 2 days - they corrode the material.
