However, many users have questions: how to properly refuel the device so as not to damage the mechanism, which remedy is best, and why the foam sometimes stops forming?

In this article, we will take a step-by-step refueling instruction with all the nuances of the Mijia model, talk about compatible detergents (including budget counterparts), and give tips for care that will prolong the life of the device. If you just bought a dispenser or experienced problems in operation, here you will find all the answers.

Technical characteristics of the Xiaomi Mijia dispenser: what you need to know before refueling

Before you start refueling, it's important to understand how the device works. Mijia's dispenser works by converting fluid into foam using a compressor and a special grid, and here are the key parameters that affect the process:

• 🔋 Capacity of the tank: 300 ml (real useful volume — ~280ml due to construction).
• 💧 Type of product: only liquid soap or gel with low viscosity (thick gels clog the mechanism!).
• ⚡ Power: 4 type batteries AA (not included in the package) or USB-C (depending on the modification).
• 🔄 Expenditure: ~0.5 ml per press (enough for a single press) ~500-600 doses).

The feature of the model is the automatic foaming when you put your hand up at a distance of 5-8 cm. The sensor works on an infrared sensor, which can malfunction if a soap film hits the lens. So always wipe the top of the dispenser with a dry wipe before refueling, this will prevent false positives.

⚠️ Attention: If the dispenser stopped releasing foam, but the batteries are charged, the problem is 90% of the time the nebulizer net is clogged. Don't try to clean it with a needle: use warm water and a soft brush.

What can be poured into the dispenser Xiaomi Mijia?

The manufacturer recommends using only the original Xiaomi soap (article) MJSXJ02YM), But in practice, the device works with other means, subject to two conditions:

1. Neutral pH: optimally 5.5-7.0. Acid or alkaline means (for example, household soap) corrode seals.

Here are the proven options that won’t hurt the mechanism:

• 🧼 Liquid soap: Dove, Fa, Nivea Soft (without moisturizing additives!).
• 🧴 Shower gels: L'Occitane (line for sensitive skin), Cien (from Lidl).

What can't be poured:

• 🚫 Thick shower gels (e.g. Garnier Fructis – clog the pump).
• 🚫 Means with scrubbing particles or peels.
• 🚫 Soap high in glycerol (crystallized in the mechanism).
• 🚫 Diluted solid soap (forms a precipitate).

⚠️ Note: If you use flavored gels, note that essential oils can leave a sticky coating on the sensor. To avoid failures, wipe the top dispenser panel with an alcohol wipe every 2 weeks.

Step-by-step: how to fill the dispenser Xiaomi Mijia

The refueling process seems simple, but many users make mistakes that lead to leaks or breakages of the pump.

Disconnect the dispenser from power (remove the batteries or disconnect the batteries). USB)

Prepare the product (if necessary, dilute with water)

Take a soaking napkin in case of strait

Check the temperature of the liquid (optimally 20-25).°C)-->

Step 1: Removal of the upper cover

Carefully press the lock (on the back of the dispenser) and pull the lid up. Don't put too much effort into it, the attachment mechanism is plastic and can break.

• 🔹 Check if the remaining soap is blocking it.
• 🔹 Try to sway the lid slightly left-right.
• 🔹 Do not use sharp objects – this will void the warranty!

Step 2: Removing the reservoir

When you take the lid off, you'll see a transparent tank with the residues of the product, and you'll take it out.

1. Turn the dispenser over the sink (so as not to spill the remains).
2. Press the two latches on the sides of the tank and pull up.
3. If the tank is not removed, check whether it is attached to the seal (carefully tuck your nail).

Step 3: Washing the tank (required!)

Even if you use the same product, the residues of the old soap can mix with the new soap and form clots.

1. Fill it with warm water (<40°C) on 2/3.
2. Add 1 tsp of vinegar or citric acid (remove lime plaque).
3. Close the lid and shake for 10-15 seconds.
4. Rinse thoroughly under running water and dry.

Important: Do not use hot water – it can deform the plastic seal!

Step 4: Refueling a new facility

Now fill in the prepared tool:

• 🔹 Fill the tank no more than 90% (up to the mark) MAX).
• 🔹 If you use a thick gel, dilute it with distilled water (1:1).
• 🔹 Avoid getting liquid on the electronic unit (top of the tank).

After gas:

1. Put the tank back in until the latches click.
2. Close the lid, making sure the lock is in place.
3. Connect the power and check the work (put your hand to the sensor).

💡

If the foam comes out too liquid, add 1 tsp of glycerol (pharmacy) per 100 ml of soap to the product. This will increase the stability of the foam without harming the mechanism.

Frequent mistakes in refueling and how to avoid them

Even experienced users sometimes face problems after refueling.-5 mistakes and their solutions:

The most common mistake is to use undiluted gels, such as Garnier Fructis or Nivea Men, which completely clogs the pump in 1-2 weeks, and if that happens, don't push it through with repeated presses, you'll burn the engine.

⚠️ Warning: If the pump continues to make noise or does not pump fluid after washing, the engine winding is likely to have burned, in which case repairs will cost more than buying a new dispenser (motor price — ~80% of the cost of the device).

How to prolong the life of the dispenser: tips for care

If properly operated, Xiaomi Mijia will last 3-5 years, here are 5 rules to help avoid breakdowns:

• 🔄 Change the product every 2-3 months, even if the tank is not empty. Over time, the soap oxidizes and forms a precipitate.
• 🚿 Wash the tank after each change of the product (see instructions above).
• 🔋 Use high-quality batteries (like Duracell or Energizer) cheap cells quickly put voltage down, which leads to sensor failures.
• 🌡️ Avoid direct sunlight – UV radiation makes plastics brittle.
• 🛁 Install the dispenser away from the shower to avoid splashing on the electronic part.

If you use a dispenser in a public place (such as an office), it is recommended that:

• 🔹 Once a week, wipe the body with antibacterial wipes.
• 🔹 Set the battery saving mode (if available in the firmware).
• 🔹 Using a transparent tool - it is easier to control the level of refueling.

💡

Regular washing of the tank with warm water with vinegar (1 time per month) prevents 90% of breakdowns associated with clogging of the mechanism.

Alternative ways of refueling: life hacks from users

The Xiaomi community has come up with a few non-obvious refueling methods that can be useful in specific situations:

1. Gasping without removing the lid (for lazy)

If the tank is almost empty, and there is no time to remove the lid, you can add the product through the sprayer hole:

1. Turn over the dispenser and find a small hole under the net.
2. Insert a thin funnel (for example, from a bottle of liquid soap).
3. Slowly pour the tool, avoiding hitting the electronic part.

The disadvantage of the method: it is impossible to wash the tank, so it is often not recommended to use it.

2. Use of concentrate

To save money, many people buy concentrated soap (like Dr. Bronner's) and dilute it with water.

• 🧼 For liquid soap: 1 part concentrate in 3 parts water.
• 🧴 For gel: 1 part concentrate on 2 parts water + 1 tsp glycerin.

Advantage: one bottle of concentrate (250 ml) is enough for 4-5 refills of the dispenser.

3. Antiseptic filling

During epidemics or for public places, the dispenser can be filled with an alcohol-containing antiseptic (with an alcohol concentration of not more than 70%).

• 🔹 Dilute the antiseptic with 1:1 water - pure alcohol corrodes the seals.
• 🔹 Do not use chlorhexidine products – it crystallizes in the pump.
• 🔹 After the antiseptic, be sure to rinse the system with water with soda.

💡

To disinfect the dispenser (e.g., after an illness), put a solution of hydrogen peroxide (3%) in the tank for 30 minutes, then thoroughly rinse it. This will kill 99% of the bacteria without harming the mechanism.
