Refueling Xiaomi dispenser with liquid soap: instructions with photos and tips for care

Xiaomi's automatic soap dispensers are not just a kitchen or bathroom gadget, but a full-fledged smart home system that saves detergent and maintains top-notch hygiene. But even such a simple device requires proper handling, especially when it comes to refueling. Wrongly chosen soap, a liquid overflow, or ignoring the cleaning mechanism can cause the dispenser to break or deteriorate.

In this article, we will discuss all the steps of refueling a Xiaomi dispenser, from choosing the right detergent to step-by-step instructions for popular models (Xiaomi Mijia Automatic Soap Dispenser, Viomi V3 and others). You will also learn how to avoid errors that shorten the life of the device, and what to do if the dispenser stopped issuing soap.

What Xiaomi Dispensers Models Support Refueling

Not all Xiaomi dispensers are refueled the same way, the main differences depend on the type of soap (touch, mechanical, pumped) and tank volume. Below is a brief overview of the most common models that are found on the market:

• 🔹 Xiaomi Mijia Automatic Soap Dispenser – classic model with infrared sensor, 300 ml tank, compatible with liquid soap and gel.

Important: foam models (like the Youpin Foam Dispenser) cannot be filled with regular liquid soap, which will lead to clogging of the mechanism. Similarly, pump-operated dispensers (like the Viomi V3) are sensitive to fluid density. More information about compatibility is available in the next section.

What soap can be poured into the Xiaomi dispenser: selection criteria

The type of detergent not only affects the quality of the dispenser, but also its resource. The manufacturer recommends using a liquid soap or gel with a viscosity of no more than 500 mPa·s (at 25 ° C) - this guarantees an uninterrupted supply without blockages.

⚠️ Warning: Never fill the dispenser with thick creams, scrubs, or solid-particle products (such as coffee grounds) that will cause the pump to break permanently. Also avoid high-oil products that leave the film on the sensors and make them less sensitive.

💡

If you use a perfumed gel, dilute it with water by 10-15% – this will reduce the risk of sludge in the tubes.

Step-by-step: how to fill the Xiaomi dispenser with soap

The refueling process is simple, but there are a few critical points that are often overlooked, such as the wrong positioning of the tank can lead to leaks, and late cleaning can lead to a clogging of the nozzle.

Preparation of the dispenser

Before refueling, disconnect the device from power (if the model is touch or smart).

• 🧼 Remove the top cover of the tank (on most models it unscrews counterclockwise).
• 🔍 Check the inside for residues of old soap or mold. Wash with warm water if necessary.
• 💧 If the tank is removable (like Viomi) V3), Remove it and rinse it under running water.

2. Cleaning agent pouring

The key here is not to overflow the liquid and avoid air entering the pump.

1. Pour the soap into the tank to the MAX mark (usually 250-400 ml depending on the model).
2. If you use concentrate, dilute it with water according to the instructions on the package.
3. Close the tank cover and tightly twist it (on Mijia models, a click should sound).

Verification of work

After refueling, connect the dispenser to the power supply and test:

• 👆 Hold your hand to the sensor (for touch models) or press the pump (for mechanical models).
• 💦 Make sure the soap is served evenly, without jerking.
• 🔊 Listen to the pump operation - there should be no extraneous noises (squeaking, coding).

⚠️ Note: If the dispenser does not give out soap after refueling, check:

• 🔌 Is it connected to the outlet (for models powered by the network).
• 🔋 Battery charge (for battery versions).
• 🚫 Is there an air plug in the tube (relevant for Viomi) V3).

Cleaning and care: how to extend the life of the dispenser

Even the best detergent will eventually leave sludge on the inside of the dispenser. Regular cleaning is the key to the long-term operation of the device. The manufacturer recommends that it be done every 2-3 months or after 5-6 refills, but if you use homemade solutions or thick gels, the interval should be reduced to 1 month.

How to clean the Xiaomi dispenser:

1. Remove the soap container and rinse it with warm water with a mild detergent (such as Fairy). Avoid abrasive sponges!
2. Cleaning the nozzle: If the soap is not served evenly, remove the nozzle and rinse it under a stream of water. For hard-to-reach places, use a cotton swab.
3. Plaque removal: When forming lime plaque (relevant to hard water), soak the removable parts in a solution of vinegar (1: 1 with water) for 10-15 minutes, then thoroughly rinse.
4. Drying: Before assembly, make sure all parts are completely dry - moisture can cause contact corrosion (in smart models).

⚠️ Warning: Do not use boiling water, harsh chemicals (such as Domestos) or metal brushes to clean your water, this will damage plastic and silicone parts, and do not disassemble the pump yourself unless you are confident in your skills (this will void the warranty).

💡

For models with touch control (Viomi V3) after cleaning, you may need to recalibrate the sensor. To do this, hold the switch on 5 seconds before the audible signal.

Typical gas station errors and how to avoid them

Even experienced users sometimes make mistakes that lead to a dispenser failure, and here are the most common ones and ways to prevent them:

• 🚫 Soap overflow: Liquid above mark MAX Leaks and soaps get into the electronics unit. Always leave 5 to 10 mm of free space.
• 🚫 Using the wrong soap: Thick gels or abrasives clog the tubes. check viscosity before refueling.
• 🚫 Ignoring cleaning: Plaque from soap reduces the life of the pump. Clean the dispenser at least 1 time every 2 months.
• 🚫 Sharp movements when installing the tank: This can damage the O-ring and cause leaks.
• 🚫 Cold soap filling: The viscosity of the liquid increases at low temperatures. If the soap was stored in the cold, let it heat up to room temperature.

One of the most obscure problems is the formation of mold in the tank, which happens when the dispenser is left unused for a long time or filled with homemade solutions without preservatives, to avoid mold:

• 🌿 Add 1-2 drops of tea tree essential oil (natural antiseptic) to your soap).
• 💧 After each use, wipe the nozzle with a dry wipe.
• ☀️ Keep the dispenser in a well-ventilated place, avoiding high humidity.

Smart functions: how to manage a dispenser through Mi Home

Viomi V3 and some versions of Mijia support connection to the Mi Home app, which opens up additional features:

• 📱 Remote control: You can turn on the soap in voice via Alice or Google Assistant (set up via Mi Home). → Smart home. → Automation).
• 🔄 Dose adjustment: In the application settings, you can select the portion size (for example, 0.5 ml, 1 ml or 1.5 ml).
• 🔔 Notifications: Dispenser will notify you of low soap levels or the need to clean.
• 📊 Usage statistics: The application keeps track of the consumption of detergent.

To connect the dispenser to the Mi Home:

1. Install the Mi Home app on your smartphone (available for Android and iOS).
2. Turn on the dispenser and put it in pairing mode (usually you need to hold the power button for 3-5 seconds until the indicator flashes).
3. In the app, click Add Device → Smart Home → Soap Dispenser and follow the instructions.

⚠️ Note: If the dispenser is not connected to Wi-Fi, check:

• 📶 Router signal (the device should be no further than 5 meters from it).
• 🔒 Network password (some models do not support networking) WPA3 — switch over WPA2).
• 📱 Mi Home version (update to the latest version).
