Xiaomi soap soap refueling: a complete guide with photos and tips

Why the right refilling of Xiaomi dispenser affects its operation

Xiaomi's automatic soap dispensers are not just a fancy gadget, but a device that, if handled improperly, can quickly fail. The main problem users have is clogging the mechanism due to the use of inappropriate liquids or sloppy refills. Unlike regular soapboxes, there is a pump, sensors and electronic components that are sensitive to the composition of the detergent.

The manufacturer recommends the use of special liquid soap with low viscosity (up to the 500 mPa·s), but some analogues are also suitable in practice, if you know the nuances, this article will help avoid the typical mistakes, from choosing consumables to step-by-step disassembly of the unit. 15%) — It destroys the silicone seals for 2-3 month.

If you’re first encountering a refueling experience, look at your device’s model. for example, Xiaomi Mijia Automatic Soap Dispenser and Viomi V3 They have different feeding mechanisms, which affect the volume of liquid to be poured and the way it is disassembled.

What soap is suitable for Xiaomi dispenser: TOP-5 tested

Not all detergents are compatible with automatic dispensers.

• 🧴 Consistency: the liquid should flow easily from the container (test - flip the bottle: if the soap drips itself, and not pouring a stream, it is too thick).
• 🔬 pH balance: optimally 5.5-7.0. Acid or alkaline products (for example, household soap) corrode plastic.
• 🚫 Prohibited components: no scrubs, particles, gels with microbeads or high oil content (more than 5%).

⚠️ Note: If you use liquid pump soap (such as Palmolive or Fairy), be sure to dilute it with distilled water in a 1:1 ratio. Otherwise, the dispenser pump will work with overload, and after 3-4 refueling will require repairs.

Step-by-step instructions: how to disassemble the unit for filling

Before refueling, the dispenser must be opened correctly. Xiaomi Mijia and Viomi have different lid mounting mechanisms:

1. Disconnect the device from the network (if it is connected to the outlet).
2. Turn the dispenser down with the sensor - so the liquid flows to the neck, and it will be easier to drain.
3. Click on the cap lock (Mijia has a button on the side, Viomi has one). V3 — bottom-latch).
4. Carefully pull the lid up. If it doesn't lend itself, don't force it, see if the rest of the soap is blocking it.

⚠️ Attention: Xiaomi Smart Soap Dispenser Pro has a magnet on the lid, and if you pull it sideways, you can damage the motion sensor. Pull it upwards!

After removing the cover, you will see:

• 🔋 Battery (in wireless models) – do not touch contacts.
• 💧 Reservoir for soap - it must be removed by pressing the latches on the sides.
• ⚙️ Pump – if it is covered with white coating, it must be cleaned (see section below).

How to fill the dispenser: nuances for different models

The refueling process seems simple, but there are critical points that even experienced users miss:

1. Rinse the tank with warm water (not hot!) and dry it. Residues of old soap may react with new soap, leading to the formation of flakes.
2. Pour the liquid to the mark. MAX (It's usually 300 to 350 ml. The overflow will cause leaks when the pump is running.
3. The Viomi model V3 After refueling, you need to manually pump the pump 2-3 times (click on the soap supply button without connecting to the network) to remove air from the system.
4. Make sure the sealing ring on the tank lid is intact.If it cracks, replace it (article for Mijia — MDZ-06-DM).

🔹 For Xiaomi Smart Soap Dispenser Pro models, calibrate after refueling. Hold the switch for 5 seconds until the indicator flashes green.

🔹 For models with mechanical pump (Viomi) V1): After assembly, check the piston's progress, it should move smoothly, without jamming. If you feel resistance, disassemble the pump and clean it of dried soap.

Mistakes that kill dispenser for 1-2 refills

Even minor defects can cause a breakdown.

• 🧼 Using a shower gel -- because of the high viscosity, the pump overheats.
• 💦 Cold water filling – if the liquid temperature is below 15°C, the level sensor may not work properly.
• 🔌 Connecting to the network during refueling - the risk of short circuit if the liquid gets to the contacts.
• 🧹 Cleaning the pump with metal objects – scratches the plastic, leading to leaks.

⚠️ Attention: If after filling the dispenser began to produce soap without pressing, the problem is the motion sensor. Most likely, you poured a soap with a high alcohol content (for example, an antiseptic) that corroded the contacts. ~800 ₽).

Another common mistake is to use undistilled water to dilute, and tap water has salts that settle on the pump and clog it, and if you don't have distilled water, boil and filter the regular water.

💡

Before the first filling of the new dispenser, wash the tank with a solution of vinegar (1 tbsp. l. per 200 ml of water) - this will remove the factory lubricant, which can react with soap.

How to Clean the Pump and Prolong the Life of the Dispenser

If the dispenser starts to give out soap in jerks or with a delay, it's time to clean the pump.

• 🧻 Paper wipes or microfibre
• 🪛 Toothpick (not metallic!)
• 💧 Citric acid solution (1 tsp per 100 ml of water)

Step-by-step cleaning:

1. Remove the tank and disconnect the pump (it is attached to latches or screws - depending on the model).
2. Load the pump in a solution of citric acid for 15-20 minutes - this will dissolve the lime plaque.
3. Carefully clean the feeding hole with a toothpick. Don't use a needle or knife - you can damage the membrane.
4. Rinse the pump under running water and dry for 2-3 hours (can be dryer in cold air).

🔹 For Xiaomi Smart Soap Dispenser Air models, cleaning is more difficult. You can't put the pump in a liquid, just wipe it with a wet wipe. Use a special spray for ultrasonic humidifiers (e.g. Boneco Cleaner) for deep cleaning).

Once cleaned, assemble the dispenser and test the distilled water, so if the pump is running smoothly, you can pour soap.

💡

The pump needs to be cleaned every 3-4 refills, even if the dispenser is working normally, which prevents the accumulation of plaque, which will eventually block the mechanism.

Alternative Refilling Methods: What to Do When the Original Soap Is Over

If you don't have the right soap, you can use homemade mixtures, and the main thing is to observe the proportions and test the viscosity.

Recipe 1: Soap + water + glycerol

• 🧼 200 ml of liquid soap (e.g. Dove or Fa)
• 💧 100 ml of distilled water
• 🧴 1 tsp glycerol (for softening)

Mix the ingredients and check the viscosity. If the mixture is too thick, add another 20 to 30 ml of water.

Recipe 2: Baby soap + essential oil

• 🧼 100 g g of grated baby soap (no fragrances)
• 💧 300 ml of hot water
• 🌿 2-3 drops of tea tree oil (antibacterial effect)

Dissolve the soap in water, cool it and add the oil. This mixture is suitable for sensitive skin, but can form a precipitate - strain through gauze before filling.

⚠️ Warning: Never use household soap - its pH is higher than 11, which destroys the plastic tank. Also avoid products with triclosan - it crystallizes and clogs the pump.
