Xiaomi Mijia automatic dispensers have become an integral part of the modern bathroom, offering hygienic and convenient hand washing. However, many owners are faced with the question of how to refuel the device to extend its life and ensure quality foam. Using the wrong liquid can lead to clogging pump or incorrect sensor operation.
In this article, we will discuss how to prepare an effective solution using the available components. You will learn about the right proportions, mixing features and subtleties of adjusting the gadget for different types of liquids.
The main challenge is to create a mixture with optimal viscosity, so that too thick a compound will overload the motor, and too liquid will not produce the desired volume of foam, so let's dive into the technical details of the process and figure out what your smart soapbox likes.
Principle of operation and requirements for liquid
Xiaomi's smart dispensers use a special pump that saturates the liquid with air, turning it into air foam. The viscosity of the solution is a critical parameter for the stable operation of the mechanism. Standard liquid soap from stores often has too dense a consistency, which requires mandatory dilution.
If you use clean soap without preparation, the device will give out a small amount of foam or completely stop working due to the valves blocking, and in addition, bacteria multiply faster in a dense environment, which is especially important to consider in conditions of high humidity of the bathroom.
The ideal solution should be uniform, without solids and clots. The water temperature when mixed also plays a role: warm water dissolves the soap base better, but before pouring the mixture must be cooled to room temperature so as not to damage the plastic seals.
⚠️ Warning: Never put abrasives, scrubs or glitters in the dispenser. Microscopic solids will instantly disable the pump mechanism.
💡
Use distilled or filtered water to prepare the solution – this will prevent the formation of scale inside the tubes of the dispenser.
Selecting the base: which soap is best to use
There are different types of soaps to make the solution, but not all of them are equally effective. The most popular option is the regular liquid hand soap, which is sold in any supermarket, and it should be neutral, without adding oils that can leave a greasy coating on the inside of the tank.
Specialty foaming products, which are often sold in large canisters, are already optimally consistent, but even they sometimes need to be slightly diluted for Xiaomi Mijia Auto Induction models. You can also use baby soap, which is usually softer and less likely to cause allergic reactions.
It is not recommended to use:
- 🧼 Shower gels with high oil content and moisturizers.
- 🧴 Shampoos with silicones and conditioning additives.
- 🚿 Washing dishes (too aggressive for the skin of the hands with frequent contact).
- 🛁 Bath fluids with mother-of-pearl and sequins.
When choosing a base, pay attention to the pH level. Too alkaline or acidic environments can eventually corrode the rubber pads inside the dispenser. The optimal is a neutral indicator close to 5.5-7.0.
Proportions and instructions for cooking
The gold standard for Xiaomi dispensers is the ratio of 1 part soap to 3-4 parts water. However, the exact proportions depend on the initial density of the chosen product. If the soap is very thick, like a gel, the ratio can go as high as 1:5.
The cooking process requires a sequence of actions. First pour warm water into a clean container, then add a soap base. Stir the solution carefully, trying not to create abundant foam in the container, as bubbles can interfere with the correct determination of the level of liquid by the sensor.
Here's a step-by-step algorithm of actions:
- 💧 Prepare clean containers and warm water (about 40)°C).
- 🧴 Measure the amount of soap required according to the chosen proportion.
- 🥄 Slowly pour the soap into the water and stir until uniform.
- ⏳ Let the solution settle for 10-15 minutes to get out the excess foam.
☑️ Testing of solution readiness
After mixing, be sure to check the uniformity of the mixture. If you see the dissection of the liquid into fractions, then the components are incompatible, and such a solution can not be used - it can clog the nozzle.
Compatibility and dosage table
For the convenience of users, we have created a table that will help determine the type of base and the necessary proportions. Different types of soap require a personal approach to achieve the ideal foaming capacity in a particular device.
| Type of basic | Recommended proportion (Soap:Water) | Features | Frequency of cleaning |
|---|---|---|---|
| Ordinary liquid soap. | 1 : 4 | It requires careful mixing. | Every 2 months |
| Foaming concentrate | 1: 2 or 1: 3 | Best foaming ability | Once in 3 months |
| Baby soap. | 1 : 3 | Soft foam, fast-consuming | 1.5 months. |
| Antibacterial agent | 1 : 4 | Can dry the skin at high concentration | Every 2 months |
The data in the table is averaged. In reality, you may need to experimentally match your dispenser to your particular brand of soap, because the chemical composition of the manufacturers is different.
💡
The key to success is to start with less soap (1:5) and gradually increase concentration until the foam is thick enough.
Configuring the dispenser after refueling
Once you've poured the solution into the tank, you need to set the device up correctly. Most Xiaomi models have a foam volume adjustment. If you're using a highly diluted solution, you may need to set a maximum feed level.
The settings usually involve a button on the top of the device or a Mijia mobile app (for Wi-Fi versions). In mechanical models, the mode switch is located under the on button. Long pressing allows you to choose from three intensity levels.
Working hours:
- 🟢 Level 1: Minimum foam, suitable for highly concentrated solutions.
- 🟡 Level 2: Standard feed, optimal for most homemade blends.
- 🔴 Level 3: maximum supply, recommended for liquid solutions or when a large portion is needed.
⚠️ Warning: Do not force the soap out by repeatedly pressing the sensor, which can cause the system to suffocate and the pump to temporarily fail.
If after refueling the dispenser makes strange sounds or does not foam, try several times to press the button manually (if there is a manual feed mode) to pump the system and remove air plugs from the tubes.
Device care and prevention
Regular maintenance of the dispenser will prolong its life, and even with the perfect solution, deposits can accumulate over time on the walls of the tank and in the pump, and it is recommended to completely wash the container with warm water at each complete liquid replacement.
Once every six months, you should do a deep cleaning, so you can put warm water in the tank with a little citric acid or vinegar, let it stand for 10 minutes, and then run the solution through the system, which will help dissolve the mineral deposits and disinfect the internal channels.
What to do if the dispenser stopped foaming?
Keep the dispenser in a place protected from direct sunlight. Ultraviolet can promote algae reproduction in a transparent reservoir and plastic degradation. Also avoid extremely low temperatures that can interfere with seal seals.
💡
In a prolonged absence (vacation), it is better to empty the tank and leave the dispenser dry with the lid open to prevent soap residues from souring.
