Xiaomi’s automatic soap dispensers have become a popular solution for maintaining hygiene in the bathroom or kitchen. These devices not only save fluids, but also make hand washing more hygienic — without having to touch the bottle. However, many users face difficulties in first filling: how to open the case, what type of soap is suitable, how to avoid leaks or clogged nozzles.
In this article, we will look at all the steps of refueling Xiaomi dispenser, from choosing the right liquid to the subtleties of disassembling and cleaning. Particular emphasis will be placed on common errors that lead to breakdowns (for example, using a thick gel or soap with abrasive particles).
What soap is suitable for Xiaomi dispenser: the choice of liquid
Not every detergent is compatible with Xiaomi automatic dispensers. The manufacturer recommends using a liquid soap or gel with low viscosity (up to 500 mPa·s), exceeding this indicator leads to nozzle clogs or incorrect dosage.
- 🧼 Liquid toilet soap (e.g. Dove, Fa, Safeguard) is the safest solution.
- 🧴 Antibacterial gels without alcohol (alcohol-containing can damage seals).
- 🧽 Handwashing fluid marked "for dispensers" (e.g. Ecolab or Deb).
- ❌ Prohibited: shampoos, shower liquids, means with exfoliating particles.
It is important to consider the pH balance of the liquid: the optimal range is 5.5-7.0. Acid or alkaline products (for example, household soap) can corrode the plastic parts of the dispenser.
How to check the compatibility of soap with a dispenser?
For models Xiaomi Mi Automatic Soap Dispenser and Xiaomi Mijia Smart Soap Dispenser manufacturer officially recommends soap with a viscosity of 300-400 mPa·s. Exceeding this value by 20% or more reduces the life of the pump by 30-40%.
Preparation of the dispenser for refueling: disassembly and cleaning
Before refueling, the device must be disconnected from the power supply (if the model is battery-powered, remove the elements).
- Remove the top cover. Most models have latches that lock it, and press both sides at the same time.
- Remove the soap tank. In some dispensers (for example, Xiaomi Mijia Smart Soap Dispenser Pro), the tank is integrated into the housing - it must be carefully pulled upwards.
- Wash the tank with warm water (not higher than 40).°C) if you are filling the dispenser for the first time or changing the type of soap.
Pay special attention to the nozzle, which is often clogged with the residue of dried soap.
- 🧹 Toothbrush with soft bristles (to remove plaque).
- 💧 Syringe with warm water (wash under pressure).
- ⚠️ Do not use needles or sharp objects – they will damage the mechanism.
💡
If the nozzle is heavily clogged, soak it in a solution of vinegar (1:1 with water) for 10-15 minutes, then rinse with water.
After cleaning, dry all parts in the air for at least 30 minutes. the humidity inside the tank can cause corrosion of the contacts (relevant for models with fluid level sensors).
Step-by-step: how to fill the dispenser of soap Xiaomi
Once the dispenser is ready, start refueling. It is important to follow the sequence to avoid leaks or failures in the pump.
Make sure the dispenser is off power.
Prepare a liquid soap with suitable viscosity
Check the cleanliness of the tank and nozzles
Prepare a funnel or measuring glass (for an exact dosage)
-->
- Pour soap into the tank: 📏 Fill the tank no more than 80% – this will prevent overflows when the pump is running. 🌀 If you use concentrated soap, dilute it with water (proportion 1:1).
Set the tank in place
- 🔄 Make sure that the sealing ring (if any) fits tightly to the edges.
- ⚠️ Do not twist the tank - it can damage the soap supply tube.
- Close the lid until a characteristic click (in models with a lid sensor, it can beep).
- Connect the power and test the dispenser, bringing your hand to the sensor.
If the soap is not served or the dispenser makes uncharacteristic sounds, check:
- 🔋 Battery charge (at low charge the pump is unstable).
- 🔄 Position of the reservoir - it should be tightly fixed.
- 💧 Liquid viscosity – if the soap is thick, dilute it with water.

Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when refueling Xiaomi dispensers, and here are the most common ones and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Use of thick gel | Nozzle clog, pump overheating | Dilute with water to the consistency of liquid soap |
| Soap pouring into the tank | Leaks, failures in the operation of the level sensor | Fill in no more than 80% |
| Cleaning the nozzle with a needle | Machine damage, soap leakage | Use a toothbrush or water under pressure |
| Use of soap with abrasives | Scratches on plastic, clogged tubes | Check the composition for the absence of solid particles |
Another common problem is that the dispenser stops working after refueling, and 90 percent of the time, it's because of:
- 🔋 Batteries discharged (especially if the device has not been used for a long time).
- 🔌 Bad contact tank - check that it is installed to the point.
- 💧 When soap hits the sensor, wipe the sensor with a dry napkin.
💡
If the dispenser does not respond to the hand, check the sensor sensitivity settings in the Mi Home app (for smart models).
How often should the dispenser be refilled and cleaned?
The frequency of refueling depends on the tank capacity and the intensity of use.
- 🏠 Home use (2-4 people): 1 refueling in 2-3 weeks.
- 🏢 Office or public place: 1 gas station in 5-7 days.
Cleaning the dispenser is recommended to carry out:
- 🧼 Every 2 refills - washing the tank and nozzles.
- 🔧 Once every 3 months – deep cleaning with disassembly (for models with a removable pump).
For models with smart features (such as Xiaomi Mijia Smart Soap Dispenser 2), you can set up cleaning reminders in the Mi Home app, and some devices also alert you to low soap levels via a notification on your smartphone.

Compatibility of Xiaomi dispensers with different types of soap: tests 2026
In 2026, users tested the compatibility of Xiaomi dispensers with popular detergents. Results (rated on a 5-point scale):
| Brand of soap | Type | Viscosity (mPa·s) | Compatibility | Notes |
|---|---|---|---|---|
| Dove Liquid Soap | Toilet | 350 | ⭐⭐⭐⭐⭐ | Perfect for all models. |
| Fa hand gel | Antibacterial | 420 | ⭐⭐⭐⭐ | Dilute with water 1:1 |
| Safeguard | Antibacterial. | 380 | ⭐⭐⭐⭐⭐ | Recommended for public places |
| Ecolab for dispensers | Professional | 300 | ⭐⭐⭐⭐⭐ | Long life of the pump |
| Homemade soap solution | Homemade | 500+ | ⭐⭐ | High probability of blockages |
For models with an infrared sensor (for example, Xiaomi Viomi Automatic Soap Dispenser) it is not recommended to use soap with pearl particles - they can scatter the sensor signal, causing false positives.
If you plan to use essential oils for flavoring, add no more than 2-3 drops per 200 ml of soap. Excess concentration can damage the plastic and cause allergic reactions.
Repair and maintenance: what to do if the dispenser breaks down?
If the dispenser stopped working after refueling, first rule out simple reasons:
⚠️ Attention: If the Xiaomi dispenser makes a buzzing sound but doesn't deliver soap, the feed tube is probably clogged. Don't try to blow it with your mouth, it can damage the pump:
- Turn the device off the power.
- Remove the tank and rinse the tube with warm water with a syringe.
- Check if the air has entered the system (knock on the body to blow bubbles).
Battery models (e.g. Xiaomi Mijia Smart Soap Dispenser Pro) have a battery discharge problem with prolonged downtime.
- 🔌 Connect to charging for 2-3 hours (even if the indicator does not burn).
- 🔄 Try resetting by holding the power button for 10 seconds.
If the device is not working, check:
- 🔧 Integrity of the O-ring – cracks lead to leaks.
- 🔌 Battery Contacts – Oxidation May Interrupt Power.
- 📱 Firmware updates (for smart models) via the Mi Home app.
