How to pour liquid soap into the dispenser Xiaomi: video + instructions with nuances

Xiaomi’s automatic soap dispensers are one of the most popular smart home solutions that combine hygiene, convenience and modern technology. However, even such a simple device has its own intricacies: improper refueling can lead to leaks, clogs or failure of the mechanism. In this article, we will discuss how to pour soap into the dispenser Xiaomi using popular models (Mijia Smart Soap Dispenser, Viomi V3, etc.), show video instructions from the manufacturer’s channels and users, and also reveal hidden settings in the Mi Home application that will prolong the life of the device.

You'll learn what types of liquids are compatible with dispensers (and why regular soap can break them), how to avoid common refueling errors, and what to do if the device stops distributing a portion, and for those who like visual guides, a selection of verified YouTube and Bilibili videos, where the process is shown in as much detail as possible.

What dosers of soap releases Xiaomi: models and their features

Xiaomi and its ecosystem (Mijia, Viomi, Yeelight) have launched several automatic dispenser models, which differ not only in design but also in feeding mechanism, tank capacity and fluid compatibility.

• 🔹 Mijia Smart Soap Dispenser is a basic model with a capacity of 300 ml, infrared sensor and support for Mi Home. AA.
• 🔹 Viomi V3 Smart Soap Dispenser - an improved version with a capacity of 400 ml, touch control and portion volume adjustment function (3 levels).
• 🔹 Yeelight Smart Foam Dispenser is a specialty foam model, with aeration system and backlight.
• 🔹 Xiaomi Youpin Smart Dispenser Pro – premium version with a capacity of 500 ml, support for Apple HomeKit and voice control via Alice or Siri.

Importantly, not all models are compatible with thick gels or antiseptics. For example, the Yeelight Foam Dispenser requires a liquid with a viscosity of no more than 1500 mPa·s, otherwise the mechanism will be clogged. Details of each model can be found in the official Mi Home app under Device → Specifications.

What soap can be poured into the dispenser Xiaomi: compatibility and prohibitions

Mistake. №1, which 80 percent of users allow, is filling the dispenser with the first soap that comes in, and the manufacturer clearly specifies in the instructions the types of liquids that are allowed, but many people ignore these recommendations.

Here’s what you can put in the dispensers Xiaomi:

• 🧼 Liquid soap with a viscosity of 1000-2500 mPa·s (check on the package). Optimal: Dove, Safeguard, Lux Soft Touch.
• 🧴 Shower gels without abrasive particles (e.g. Nivea Soft, Garnier Fructis).
• 🦠 Alcohol-based antiseptics (up to 70% alcohol), but only in models labeled Alcohol-Compatible (e.g. Viomi) V3 Pro).
• 🫧 Special refills for foam dispensers (for example, Yeelight Foam Refill).

What is forbidden to fill (risk of breakdown!):

• ❌ Thick cream soaps (e.g. Palmolive Natural) clog the pump).
• ❌ Soap with exfoliating particles (scrabs, peels).
• ❌ Body oils or shampoos (form a film on sensors).
• ❌ Homemade mixtures based on vinegar / citric acid (corrosion of metal parts).

💡

Before the first filling, check the viscosity of the soap with a simple test: turn the bottle over - if the liquid flows freely (like water), it can be used. If it flows slowly or drips, dilute with warm water in a 1:1 ratio.

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

The refueling process seems intuitive, but there are 3 critical points that even experienced users miss: the correct position of the tank, removing air from the system and calibrating the sensor. Let’s take each step with the example of the Mijia Smart Soap Dispenser model (for other models, the nuances are indicated in the table below).

1. If you use a thick soap, dilute it with distilled water (proportion 3: 1). For antiseptics, check the alcohol concentration (maximum 70%).
2. Removal of the top cover Press the latch on the back of the dispenser (on the Viomi V3, turn the lid counterclockwise). Don't pull force - the mechanism is fragile!
3. Take the tank carefully, hold it by the handle. Don't touch the inner tube, it's connected to the pump.
4. Fill the tank to 80% (not to the edges!) For models with foam (Yeelight) use only special cartridges.
5. After installing the tank, press the feed button 3-5 times until a uniform jet goes. This will remove the air traffic jams.
6. In the Mi Home app, go to Device Settings → Calibration and follow the instructions (you need to press the feed button 10 times in a row).

Check the viscosity of the soap | Clear the tank of residues of old liquid | Make sure the batteries are charged (voltage not lower than 1.2V) | Close the lid before clicking

Other models may have different processes, such as the Viomi V3, which requires resetting the in-app portion counter after refueling, and the Yeelight Foam Dispenser, which requires shaking the tank to distribute the foaming agent evenly.

Video Instructions: the best guides for refueling dispensers Xiaomi

Visual manuals often help better than textual ones, and we selected 5 verified videos detailing how Xiaomi refuels, cleanses and adjusts dispensers, all in Russian or subtitles:

Notice the video about the refueling errors, which shows hidden details that are not in the official instructions, such as why the dispenser releases air after changing the soap the first 5-7 taps, and how to fix this indiscriminately.

Common Mistakes and How to Avoid Them

Even after reading the instructions, users make the same mistakes, and we have collected the TOP-5 problems when refueling Xiaomi dispensers and how to solve them:

1. The dispenser doesn't give out soap after refueling. The solution is: press the feed button 10-15 times in a row or shake the device slightly.
2. Soap flows by itself, because it's a tank overflow or a valve clogging, so you can reduce the fluid level to 70 percent and clean the nozzle with a toothpick.
3. Weak pressure or intermittent jet Cause: thick soap or discharged batteries. Solution: dilute the soap with water or replace the batteries (optimally, Eneloop batteries).
4. The sensor doesn't work on your hand, because it's contaminated with the IR sensor or low sensitivity, so you can wipe the sensor with an alcohol wipe and increase the sensitivity in the app settings.
5. E1 or E2 error on display: pump malfunction or short circuit. Solution: reset the device to factory settings (press the feed button for 10 seconds).

💡

If the dispenser stopped working after refueling, 90% of the time the problem is in the air traffic jam or thick soap. Don't rush to bring it to the service: try resetting the settings first and clear the tube.

For models with Mi Home connectivity (such as the Viomi V3), it is useful to enable low-soap notifications.

Device profile → Settings → Notifications → Low fluid level (enable)

This will help to avoid a situation where the dispenser suddenly stops working due to an empty tank.

How to clean the dispenser Xiaomi: step-by-step guide

Regular cleaning extends the life of the device by 2-3 times, and the manufacturer recommends it every 2-3 months (or more often if you use perfume soap).

1. Preparation: Turn off the dispenser (remove the batteries) and pour the remaining soap into a separate container (reusable).
2. Disassemble Remove the top cover and remove the tank. disconnect the silicone tube from the pump (carefully, no jerks!).
3. Clean the tank Wash the container with warm water with a mild detergent (for example, Fairy). To remove plaque, use a brush with soft bristles.
4. Clean the tube and pump: Run the tube with vinegar (proportion 1:1) or use a syringe to wash.
5. Dry all the parts for 2-3 hours (do not use a hair dryer!) and collect the dispenser and fill with clean water for test check.

💡

Never use metal objects (needles, wire) to clean the pump, which will damage the membrane. Optimally, a toothpick wrapped in soft cloth.

For Yeelight models, you need to clean every month because the foaming agent clogs the system faster, and you have a special brush with these dispensers, and you can use it to clean the aerator net.

Hidden settings in Mi Home to optimize the operation of the dispenser

Few people know, but the Mi Home app has advanced settings that allow you to fine-tune the dispenser to your needs, which are not specified in the standard instructions, but greatly improve the user experience.

• 🔧 Size of portions (only for Viomi) V3 Youpin Pro: from 0.5 ml to 2 ml. Optimal for children - 1 ml, for adults - 1.5 ml.
• 🔧 Sensor sensitivity: 3 levels (low/medium/high) In high sensitivity, the dispenser will even activate the hand movement 10 cm from the sensor.
• 🔧 Power saving mode: turns off backlight and reduces the frequency of the sensor survey (prolongs the life of batteries by 20-30%).
• 🔧 Voice prompts (for models with a speaker): turning on the sound signal when issuing a portion (useful for people with visual impairments).
• 🔧 Schedule: You can program the disabling of the dispenser at night (for example, from 23:00 to 7:00).

To access these settings:

1. Open the Mi Home app and select your dispenser.
2. Go to Settings. → Additional functions.
3. Activate Power User Mode (SMS confirmation may be required).

Please note that after changing the settings, the dispenser may require recalibration. To do this, click Calibration → Start and follow the instructions on the screen.
