Xiaomi dispenser: how to properly refuel and avoid mistakes

Xiaomi dispensers are smart devices that automate everyday tasks, from dispensing liquid soap to spraying flavors. However, many users face problems when first filling up: leaks, sensor malfunctions or rapid liquid consumption. In this article, we will examine all the nuances of refueling popular models of Xiaomi dispensers, including Mi Automatic Soap Dispenser, Mijia Smart Aromatherapy Diffuser and others.

The brand's smart stuffing features fluid level sensors, wireless control via Mi Home and automatic dose calibration, but even these advanced gadgets require proper handling, and we'll tell you which fluids are suitable for different models, how to avoid breakages during refueling, and what to do if the dispenser stops working after changing the contents.

Important: Xiaomi’s dispensers instructions often differ by device generation, for example, the tank mounting mechanism changed in the 2023-2026 models, and the sensor sensitivity settings were added to the firmware, and we took these nuances into account and collected relevant information for all versions.

What Xiaomi dispensers are and how they differ

Xiaomi brand produces several types of dispensers, each designed for specific tasks, the main differences are in the type of spray liquid, tank volume and control method.

The most popular models:

• 🧼 Mi Automatic Soap Dispenser for liquid soap, antiseptic or lotion, equipped with an infrared sensor, powered by batteries or USB. Volume of tank: 250-300 ml.

The key difference is the type of liquid that can be refueled, for example, Mi Automatic Soap Dispenser does not allow oils or alcohol-containing solutions to be poured (this will damage the pump), and Mijia Aromatherapy Diffuser, on the contrary, is designed only for them.

• 🔋 Power: batteries (AA/AAA), battery USB-cable.
• 📱 Control: mechanical buttons, sensor, Mi Home app.
• 💧 Fluid consumption: from 0.5 ml (aromadiffusers) to 3 ml (dispensers for creams) per operation.

Before refueling, be sure to check your dispenser model – the information is listed on the box or in the settings of the Mi Home application (Devices section). If you use an unoriginal liquid, you risk clogging the sprayer or corrosion of internal parts.

What liquids can be filled in the dispenser Xiaomi

The type of liquid not only affects the device, but also its life. Xiaomi recommends the use of original consumables (for example, liquid soap Mi Liquid Soap or aromatic capsules Mijia Aroma Capsule), but in practice, many users successfully refuel dispensers with alternative means.

Acceptable liquids for popular models:

If you are planning to use non-original liquids, consider:

• 💡 Viscosity: too thick products (like honey or scrubs) will clog the pump. Optimal consistency - like liquid soap.
• 🧪 Chemical composition: Avoid products with acetone, chlorine or large particles (such as bath salts).
• 🌡️ Temperature: Don't fill hot liquids - this deforms the plastic tank.

⚠️ Attention: In the dispensers of Mijia Aromatherapy Diffuser, you can not use pure essential oils without dilution - this will lead to breakage of the ultrasound membrane. Optimal proportion: 10 drops of oil per 100 ml of distilled water.

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

The refueling process varies from model to model, but the overall algorithm is the same, so we're going to take a generic instruction with nuances for different devices.

Preparation for refueling:

1. Turn off the dispenser from power (take out the batteries or disconnect). USB-cable).
2. If the tank is left old liquid, completely remove it and wash the container with warm water (except aromadifusers - they are enough to wipe with a napkin).
3. Prepare the liquid: for Mi Automatic Soap Dispenser, you can dilute too thick soap with water (proportion 1:1), for Mijia Aromatherapy, mix water with oil in a separate container.

Refilling of the tank:

1. Remove the top cover of the dispenser (usually it is unscrewed counterclockwise or removed by pressing the latch).
2. Remove the tank: in Mi Automatic Soap Dispenser models it is pulled upwards, in Viomi Shower Dispenser it is snapped off the side.
3. Pour the liquid to the maximum level (usually 80-90% of the volume to avoid leaks). For convenience, use a funnel or syringe without a needle.
4. Install the tank back, making sure it sat tightly in place (there should be a click or resistance).

Verification of work:

1. Connect the power and turn on the dispenser.
2. For models with a sensor (Mi Automatic Soap Dispenser), hold your hand at a distance of 5-10 cm, the dose should work. If the liquid does not come in, check:

• 🔋 Battery charge (at low charge, the sensor may not work).
• 💧 Liquid level (if less than 10%, the pump is blocked).
• 🔧 Proper assembly (check if the tank is skewed).

Check the model of the dispenser and the compatibility of the liquid

Disconnect the device from power

Clean the tank of residues of old liquid

Prepare the liquid (dilute, strain if necessary)

Make sure the tank cover is tightly closed after refueling-->

For Mi Home controlled dispensers (such as Mijia Aromatherapy Diffuser) after refueling, you may need to calibrate. Go to the application, select the device and click "Update Data" or "Reset the liquid counter."

⚠️ Warning: If after refueling the dispenser begins to leak, immediately disconnect it from the power supply and check: Integrity of the sealing ring on the tank (a common cause of leaks in Viomi models). Proper installation of the pump (in Youpin Smart Lotion Dispenser, the tube must be immersed in liquid for 1-2 cm). Frequent errors during refueling and how to avoid them Even experienced users sometimes make mistakes that lead to breakdowns or improper operation of the dispenser. TOP-5 Problems and ways to solve them. 1. The dispenser does not spray the liquid after refueling: 🔌 A spray clogging - residues of old liquid or dust block the hole. Solution: rinse the nozzle with warm water or brush with a toothpick (carefully!). 🔋 Discharged batteries – sensor dispensers are sensitive to voltage. Solution: Replace the batteries with new ones (alkaline batteries are recommended). 📉 Incorrect assembly - the tank is not fully inserted or skewed. Solution: disassemble and reassemble the device following the instructions. 2. The fluid flows out of the reservoir Causes: 💦 Overflow – in some models (Mi Automatic Soap Dispenser 2) the maximum level of liquid below the neck is 5 mm. 🛠️ Wear of the O-ring - over time, the rubber loses its elasticity. Solution: replace the ring (you can order a spare part from official Xiaomi sellers). 🌡️ Abrupt temperature change -- if you put cold liquid in a warm dispenser, you create condensate. Solution: let the liquid heat up to room temperature before refueling. 3. The dispenser gives out too much or too little liquid: ⚙️ Incorrect settings in the application - in Mi Home you can adjust the dose. Solution: go to the device settings and calibrate the dosage. 🧴 Inappropriate viscosity of the liquid - too thick means squeezed out in portions. Solution: dilute the liquid with water or distilled alcohol (for antiseptics). 4. Extraneous noise or vibration when working Causes: 🔊 Air entering the pump - if the reservoir is incomplete, the pump "takes" air. Solution: add the liquid to the recommended level. 🛑 A foreign object in the mechanism, like a piece of a bottle label. Solution: disassemble the dispenser and clean the internals. 5. Mi Home app doesn't see the dispenser after filling the cause: 📶 Communication failure - if the dispenser was off the power for a long time, it can "fall off" from the network.Solution: reset the device (take out and insert the batteries) and reconnect to Mi Home. 🔄 Update firmware – after refueling, some models require software updates. Solution: check for updates in device settings. 💡If the Mijia Aromatherapy Diffuser dispenser starts to emit an unpleasant odor, add 1-2 drops of vinegar to the water the next time you refuel it will remove lime plaque and bacteria. How to clean the Xiaomi dispenser after refueling Regular cleaning prolongs the life of the device and prevents blockages. The frequency of cleaning depends on the type of liquid: 🧼 Soap/antiseptic: Clean every 2-3 weeks. 🌿 Essential oils: clean after each 3-4 refill (oils leave a sticky plaque). 🚿 Shampoo/ shower gel: clean once a month. Step-by-step cleaning: Turn off the dispenser. Remove the tank and rinse it with warm water with a mild detergent (such as dishwashing fluid). For aromadifusers, use distilled water. Clean the spray nozzle: For Mi Automatic Soap Dispenser: Wash under a stream of water and brush with a toothpick. For Mijia Aromatherapy Diffuser: Use a cotton swab dipped in alcohol (not essential oil!). Dry all the parts in the air (do not use a hair dryer or battery - plastic can deform). For deep cleaning (if the dispenser has not been used for a long time or the liquid inside thickened): Soak the tank in a solution of water and vinegar (1:1) for 30 minutes. To remove lime plaque in the aromadiffuser, use citric acid (1 tsp. per 100 ml of water). Do not use abrasives (such as soda powder) – they scratch the plastic. ⚠️ Attention: Viomi Shower Dispenser dispenser dispenser does not clean the internal mechanism with water, this will lead to corrosion of metal parts. Use only a dry wipe or alcohol wipes. What to do if the dispenser stops turning on after cleaning? If the device does not respond to buttons or sensors after cleaning, check: 1. Battery contacts - they may have oxidized. wipe them with a blower or alcohol. 2. Close density - some models have a protective contact that opens when assembled incorrectly. 3. If the water is on the board, dry the dispenser in rice or silica gel for 24 hours. If the problem persists, contact the service center (Xiaomi dispensers have a 12-month warranty). Xiaomi dispensers consume liquid sparingly, but there are ways to make them even more efficient. Here are some proven life hacks: 1. Dosage adjustment in the application B Mi Home for most dispensers can change the amount of dispensing: Open the device in the app → Settings → Dosage volume. Mi Automatic Soap Dispenser options available: 0.5 ml, 1 ml or 1.5 ml. For Mijia Aromatherapy Diffuser, you can adjust the spray intensity (low / medium / high). Tip: for an antiseptic, a minimum dose (0.5 ml) is enough, and for a thick cream, it is better to choose the maximum (1.5 ml). 2. Use of diluted liquids Many funds can be diluted without loss of effectiveness: 🧴 Liquid soap: dilute with water 1: 1 - this will reduce the consumption by 2 times. 🌿 Essential oils: instead of 10 drops per 100 ml of water, add 5-7 drops - the aroma will be as rich. 🧴 Lotions and creams: if the product is too thick, add 10-15% distilled water. 3. Optimization of operating modes for dispensers with a timer (Mijia Aromatherapy Diffuser): Set a schedule (for example, only for the night or in the morning). Use Economy mode – spray every 30 minutes instead of 15. Turn off the backlight if you don’t need it (this will save battery power). 4. Storage of liquids To prevent the liquid from spoiling and thickening: Store spare bottles in a cool place (not in the bathroom where there is high humidity). For aromadiffusers, use dark glass bottles - this will prevent the oxidation of oils. Do not mix different liquids in the same tank (such as soap and antiseptic) - this can cause a chemical reaction. 5. Prevention of blockages So that the pump does not clog: Before filling, filter the liquid through gauze (especially if it is homemade). Once a month, wash the nozzle with distilled water (even if it is externally clean). Do not leave the dispenser empty for long - this leads to drying out of the fluid residue inside the pump. 💡Diluting fluid and adjusting the minimum dose in the Mi Home app can reduce consumption by 2-3 times without losing effectiveness. What to do if the dispenser Xiaomi broke after refueling If after refueling the dispenser stopped working, do not panic - in 80% of cases, the problem can be solved yourself. Let's analyze the typical breakdowns and ways to fix them. 1. The dispenser does not turn on Actions: Check the power source: For batteries: replace with new (even if the old "seem to work"). For USB: try another cable or power unit (current at least 1A). Reset: most dispens have a Reset button (usually on the bottom panel). Press it with a toothpick on the liquid for 5 seconds. If the device is reloaded from the device, it is loaded on the device, it should be installed on the device for 2nd, it from the device, it should be installed on the device. Disassemble the dispenser and check if a foreign object has entered the mechanism (for example, a piece of label). If the pump is clogged, rinse it with distilled water with a syringe (do not use a needle!). 3. Leaking fluid from the action body: Examine the sealing ring - if it is torn or deformed, replace it. Check if the tank cracks (especially if you used hot liquid). If the leak from under the lid, try to change the batteries - sometimes this is due to incorrect liquid operation 5. Mi Home shows the Action Error: Update the Mi Home app to the latest version. Reboot the router - sometimes errors are associated with loss of communication. Remove the dispenser from the application and add it again (this may require resetting the settings on the device). If none of these methods worked, please contact Xiaomi Service Center, and in Russia and CIS countries, official support is provided by partner centers (the list can be found on mi.com in the "Service" section). The warranty on dispensers is usually 12 months, but does not apply to breakdowns due to the use of incompatible liquids.
