How to properly dilute soap for Xiaomi dispenser: proportions and tips

Xiaomi’s automatic liquid soap dispensers (MiJia, Viomi or Mijia Smart Soap Dispenser) have become an integral part of smart bathrooms, saving washing costs, dosing a serving perfectly for one use, and even synchronizing with a smartphone via Mi Home. But many users face a problem: factory soap runs out quickly and original cartridges are expensive. The solution is to dilute ordinary liquid soap on your own, but it’s important to keep proportions to avoid spoiling the device’s mechanism.

In this article, you will find proven ratios for diluting soaps of different types (antibacterial, baby, sensitive skin), learn what errors lead to clogging of the dispenser, and get instructions for cleaning the system when using “non-original” solutions. We also tested popular brands of soap (for example, Sano, Dove, Eared Nanny) and selected the optimal proportions for each option.

⚠️ Important: Not all Xiaomi dispensers respond equally to homemade solutions.Infrared sensor models (e.g. Viomi) V1) If the device stops giving out soap or flashes red after refueling, see what to do if the dispenser does not work».

What soap can be used in Xiaomi dispenser

The manufacturer recommends that you only refuel the device with original cartridges labeled MiJia or Viomi, but in practice other options are suitable.

• 🧼 Consistency: Liquid soap should be low or medium viscosity.Dense gels (for example, for shower) clog the pump.
• 🧪 pH neutrality: Optimal level - 5.5-7. Acid or alkaline solutions are corroded by sealants.
• 🚫 Abrasive-free: Scrubs, particles, or salt crystals (in some antibacterial soaps) damage the mechanism.
• 🌿 Environmentally friendly: Soap with aggressive surfactants (for example, SLS) It can leave sticky sludge on sensors.

Best suited:

• 🧴 Baby Liquid Soap (without fragrances, such as Eared Nanny or Bubchen).
• 🧼 Antibacterial soap marked “for sensitive skin” (Sano, Dettol).
• 🧽 Kitchen detergents marked "for hands" (Fairy for hands, AOS).

⚠️ Warning: Do not use shower gels (even diluted ones) - they contain silicones that form a film on the inside of the dispenser. Also avoid soaps with oils (such as Dove with carite oil) - they oxidize and clog the tubes.

Optimal proportions for soap dilution

Soap-water ratios depend on the original viscosity of the product and the dispenser model, and the following are the proven proportions for popular brands:

If you're using Viomi, it's critical. V2 or Mijia Smart Soap Dispenser with auto-dose function, dilute the soap strictly in a ratio of 1:1.5. A more liquid solution will lead to a "overflow" (the device will give out a double serving).

To check the consistency before refueling:

1. Mix the soap with water in a separate container.
2. Turn the bottle over - the liquid should flow out in drops, not a jet.
3. If the solution is too thick, add another 10-15% of the water.

Mix soap and water in a separate clean container

Check the consistency (drop test)

Filter through gauze (if there are lumps)

Leave 10-15 minutes before refueling

Do not use metal spoons for stirring-->

Step-by-step instructions for filling the dispenser

Before you pour diluted soap, you need to prepare the device and clean the tank of the residues of the previous solution.

1. Turn off the dispenser from power (take out the batteries or disconnect). USB-cable).
2. Remove the top cover: For MiJia Basic: press the latch on the back and pull up. For Viomi V1/V2: turn the lid counterclockwise.
3. Remove the tank (if it is removable) and rinse with warm water. Use a needle syringe (without a needle!) to clean the tubes and blow them with air.
4. Dry all the parts in the air for 10-15 minutes. Do not use a hair dryer or paper towels (may remain villi).
5. Tuck the solution: Pour the soap to the mark MAX (For models with a pump (for example, Viomi). V2) Pour slowly to avoid bubble formation.

Set the lid.

0.5–0.7 ml

⚠️ Warning: If the dispenser gives out soap unevenly after refueling, then there is still air in the system:

1. Turn the device upside down.
2. Press the dispenser 3-5 times until a uniform stream goes.
3. Return the dispenser to its original position.

💡

If the soap in the dispenser has started to "flake" out, add to the solution 1 teaspoon of glycerol (sold in the pharmacy) per 100 ml of the mixture. This will prevent stratification and improve the sliding of the fluid through the tubes.

Frequent Mistakes and How to Avoid Them

Incorrect dilution or refilling of the soap can lead to a breakdown of the pump, clogged tubes or incorrect sensors.

• 🚰 Tap water use: chlorine and hardness salts form a precipitate. Use distilled or boiled water.
• 🧴 Stir in the tank: Soap can foam and block the valve. Mix only in a separate container!
• 🔥 Hot water:
• 🧼 Mixing different brands: Components can react and form flakes (e.g., Sano) + Dove).
• 🔋 Refueling with power on: The pump can work spontaneously and pour soap electronic board.

If the dispenser stopped working after refueling:

⚠️ Warning: Don't disassemble the device yourself, it will lead to a loss of warranty. First try resetting: Hold the power button for 10 seconds. Remove the batteries for 1 minute. Fill the original cartridge (if any) and check the work. If the problem remains – contact the Xiaomi service center with a check.

How to clean the dispenser when using homemade solutions

Even with proper soap dilution, sediment and bacteria accumulate in the tubes and pump. Clean the device every 2-3 weeks (or more often if you use non-original solutions).

Step-by-step cleaning:

1. Empty the tank and rinse it with warm water with vinegar (1 tbsp. spoon per 200 ml of water).
2. Blow the tubes: For MiJia Basic: use a 10 ml syringe with warm water. For Viomi: turn on the cleaning mode in the Mi Home app (Device settings section).
3. Disinfection: Pour chlorhexidine solution of 0.05% (sold in a pharmacy) into the tank for 10 minutes. Rinse 2-3 times with clean water.

Drying

For models with a UV lamp (for example, Viomi) V2 Pro):

• 💡 Enable UV cleaning mode in the app after each refueling.
• ⏳ Duration of the session – 3-5 minutes (do not exceed, so as not to damage the plastic).

💡

Use distilled water to dilute soap, which will extend the life of the pump by 30-40%.

Alternative solutions: what else can be poured into the dispenser

In addition to liquid soap, other detergents can be filled into Xiaomi dispensers, but with reservations:

⚠️ Note: If you are filling an antiseptic, note that models with an infrared sensor (Viomi) V1) They can be falsely triggered by the vaporization of alcohol:

• Turn off the auto-dose function in the Mi Home app.
• Use the Manual Feed mode (button on the body).

Comparison of the original Xiaomi soap and homemade solutions

The manufacturer claims that only the original cartridges guarantee the durability of the device, but in practice, the difference is not so critical if you follow the dilution rules.

Bottom Line: Homemade solutions save 5-10 times the budget, but require more frequent cleaning of the dispenser. If you want reliability and do not have time to care, you should use original cartridges. MiJia Basic models are suitable for experiments (they are less sensitive to the composition of soap).

💡

Savings on homemade solutions pay off the risks only with regular cleaning of the dispenser (once every 2 weeks).
