Xiaomi's automatic liquid soap dispensers are not just a gadget for the lazy, but a complete solution for hygiene in a smart home. They save detergent consumption, dose a portion with milliliter accuracy, and even remind you to replenish your supplies through the Mi Home app. But here's the paradox: many users face problems when they first refuel — the device does not recognize the soap, gives an error or simply refuses to work. What's the matter?
The reason most often lies in three things: the wrong type of detergent, the wrong pouring technique or ignoring the features of a particular model (and Xiaomi has at least five of them: from budget MiJia to premium Viomi with UV sterilization). In this article, we will analyze the unique viscosity requirements of soap for Xiaomi dispensers (yes, this is critical!), show a step-by-step photo instruction and warn against typical errors that lead to a failure of the mechanism — FAQ answer questions that users are embarrassed to ask openly (for example, can you pour into the dispenser Fairy or dishwashing product).
What dosers of soap releases Xiaomi: an overview of models and their features
There are several lines of dispensers from Xiaomi on the market, each with its own refueling nuances. Here are the key models you may have come across on sale:
- 🔹 Xiaomi MiJia Automatic Soap Dispenser - Basic model with infrared sensor, tank volume 300 ml. Sensitive to soap density (optimally 1000-1500 mPa·s).
- 🔹 Viomi Smart Soap Dispenser - premium version with UV lamp for sterilization, capacity of 350 ml. Supports viomi.app for remote control.
- 🔹 Xiaomi Youpin Automatic Foam Dispenser - specializing in foam, requires dilution of soap with water in a ratio of 1:3.
- 🔹 Deerma DX700S — budget version with a mechanical pump, compatible with soap viscosity up to 2000 mPa·s.
The main difference between the models is the type of pump:
MiJia and Viomi use a peristaltic pump that “does not like” thick gels and abrasive particle products (such as scrubs).
Deerma DX700S is equipped with a piston mechanism, less fastidious to consistency, but more noisy.
If you are unsure of your dispenser model, check the labeling on the bottom or in the Mi Home app (Devices section). Viomi dispensers with a UV lamp require a mandatory wash with distilled water after each soap change - otherwise the sensor will get clogged with sediments.
What soap is suitable for Xiaomi dispensers: consistency and composition requirements
Not every liquid soap is compatible with automatic dispensers, but the basic criteria for choosing are:
| Parameter | Optimum | Permissible. | Forbidden. |
|---|---|---|---|
| Viscosity | 1000-1500 mPa·s | up to 2000 mPa·s (with dilution) | over 3000 mPa·s (gels, creams) |
| pH | 5.5–7.0 | 8.5 | over 9.0 (alkaline means) |
| abrasive | No. | Fine particles (up to 0.1 mm) | Scrubs, peels. |
| Foaming | Moderate. | Weak (requires dilution) | Strong (pump clogs) |
The best options for refueling:
Liquid soap brands Dove, Palmolive (series "Gentle care"), Ecover.
Antiseptic gels without alcohol (for example, Sanitelle).
- Tools for automatic dispensers (special line from Xiaomi Youpin).
What can't be poured:
- Means for washing dishes (Fairy, AOS) - high foaming will clog the mechanism for 2-3 uses.
- Gel antiseptics with alcohol content >60% - corrode the pump pads.
Homemade soap solutions based on household soap - crystallize when drying.
💡
Before the first filling of the new dispenser, wash the tank with warm water with vinegar (1:10) - this will remove the factory lubricant from the mechanism and prolong its service life.
Step-by-step: how to pour soap into the dispenser Xiaomi
The refueling process is simple, but the details matter. Follow this algorithm to avoid errors:
- Preparation of soap: - If the soap is thick (for example, Dove Cream), dilute it with distilled water in a ratio of 3:1 (3 parts soap, 1 part water). - For foam dispensers (Youpin Foam), dilution is mandatory - 1:3.
- Cleaning the dispenser: - Remove the upper cover (on MiJia - turn counterclockwise, on Viomi - press the latch). - Wash the tank and tube with warm water, dry for 10-15 minutes.
- Pour: - Pour soap to the MAX mark (usually 250-300 ml). Do not overflow - this leads to leaks! - For models with a pump at the bottom (such as the Deerma DX700S), use a funnel to avoid soap entering the mechanism.
- Installation of the cover: - Twistle the cover before clicking (on Viomi, check that the UV lamp is sealed). - Connect the dispenser to power (if it is a network model).
- Calibration: - Press the reset button (usually hidden under a rubber plug) and hold for 5 seconds. - The dispenser will give a test portion - check its volume (should be 0.8-1.2 ml).
Check the viscosity of the soap with a viscometer or a “folk method” (should drain from a spoon in 2-3 seconds) |
Clean the tank from the residues of the previous tool |
Use only distilled water for dilution |
Do not mix different types of soap in one dispenser-->
If the dispenser does not work after refueling:
1. Check that the cover is tightly closed (there is a leakproofness sensor on the MiJia).
2.Make sure that the soap is not popało into the pump vents.
3. Reboot the device (turn off power for 30 seconds).
⚠️ Warning: If the dispenser is grinding or not giving out a portion after pouring the soap, turn it off immediately and flush the system! This is a sign that the pump is clogged with crystallized particles or too thick a means.
Typical gas station errors and how to avoid them
Even experienced users of Xiaomi smart equipment sometimes make mistakes that lead to a break in the dispenser.
- 🚫 Using undiluted gel -- for example, Nivea Soft in its pure form thickens the tubes and blocks the pump. Solution: dilute to the consistency of liquid soap.
- 🚫 Mixing different agents - residues from the previous soap can react with the new soap to form flakes. Solution: flush the dispenser after each change of the remedy.
- 🚫 Ignoring calibration - without setting the portion, the dispenser will give out too much or too little soap. Solution: calibrate after each refill.
- 🚫 Abrasives pouring - even small particles in scrubs scratch the insides of the pump.Solution: Use only homogeneous liquids.
Pay special attention to the storage of the dispenser:
Don’t put it under direct sunlight – the soap can be dissected.
Avoid high humidity areas (such as near a shower without protection) – this leads to corrosion of contacts.
If the dispenser is not used for more than a week, drain the soap and wash the tank.

How to prolong the life of the dispenser: care and maintenance
The average life of Xiaomi dispensers is 2-3 years when used correctly, to avoid premature failure:
- Monthly cleaning: - Wash the tank and tube with vinegar solution (1:10) or a special cleaner for coffee machines. - For models with a UV lamp (Viomi), clean the quartz tube with an alcohol napkin.
- Pump prevention: - Once every 3 months, pour distilled water into the dispenser and turn it on for 10-15 minutes - this removes deposits on the mechanism.
- Scale protection: If you use hard water to dilute, add antinakipin (1 tablet per 1 liter).
- Firmware Update: - Check for updates in Mi Home - newer versions often fix dosage bugs.
For models with a battery (Viomi Portable):
Charge only with the original cable (voltage 5V/1A).
Do not leave on charging more than 4 hours - this reduces the battery capacity.
Once every six months, perform a full discharge/charging cycle to calibrate the controller.
⚠️ Note: If the dispenser starts spitting with soap or delivers portions unevenly, this is a sign of wear and tear of the pump valve. In this case, a replacement mechanism is required - contact the Xiaomi service center (the warranty covers such repairs for 12 months).
Alternative ways to use Xiaomi dispenser
Xiaomi dispensers are universal – they can be adapted for different tasks:
- 🧴 For lotion or cream, dilute the product with water to a viscosity of 1200-1500 mPa·s. Suitable for MiJia and Viomi (but not for foam models!).
- 🧼 For shampoo or conditioner, use only sulfate-free products (such as Natura Siberica) to avoid precipitation.
- 🧹 For floor detergent, dilute the concentrate in a 1:10 ratio. Important: after each use, wash the nozzle!
- 🎨 For acrylic paints – artists use dispensers for accurate paint delivery (viscosity up to 2000 mPa·s).
For experiments with alternative liquids:
1.Always test the product for compatibility - pour a small portion (50 ml) and observe the pump operation during the day.
2. Increase the frequency of cleaning to 1 time in 2 weeks.
3. discard products with a strong smell - they can damage plastic parts (for example, essential oils in concentration > 5%).
💡
Xiaomi dispensers with peristaltic pump (MiJia, Viomi) are categorically incompatible with oils and fatty substances - this leads to swelling of hoses and leaks.
