Xiaomi’s automatic soap dispensers have become an integral part of modern smart bathrooms and kitchens. These compact devices not only save cleaning product consumption, but also make hand or dishwashing more hygienic — without having to touch the bottle. But many users are asking: how to refill the dispenser, what soap is right, and why the device can stop working after the wrong pouring?
In this article, we will explore all the nuances of refueling Xiaomi dispensers, from choosing a compatible soap to step-by-step instructions for popular models such as Xiaomi Mijia Automatic Soap Dispenser or Viomi V1. You will also learn how to avoid common errors that lead to clogging of the mechanism or leaks of fluid.
Spoiler: The refueling process takes no more than 5 minutes, but using the wrong soap (for example, with abrasive particles or high viscosity) reduces the life of the device by 2-3 times.
What soap is suitable for Xiaomi dispensers: the full list
Not every detergent is compatible with automatic dispensers, and the manufacturer recommends using liquids with specific characteristics to avoid breakdowns.
- 🧼 Consistency: The liquid should be moderately fluid (like water). Thick gels or creamy soaps clog the pump.
- 🔬 Absence of abrasives: No scrubbing particles (even microscopic ones) – they damage the interior details.
- 🧪 Neutral pH: optimally 5.5-7.0. Acid or alkaline agents corrode seals.
- 🌿 Oil-free and fat-free: Essential oils or fatty components leave a film on the sensor and tubes.
Among the proven brands that are suitable for Xiaomi:
| Brand | Name of product | Type | Notes |
|---|---|---|---|
| Simple | Liquid hand soap | Antibacterial. | Suitable for all models, not foaming |
| Dove | Dove Original | Moisturizing | Dilute with water 1:1 with high viscosity |
| Ecover | Zero for hands | Eco-soap | Without SLS, perfect for sensitive skin |
| Viomi | Original soap for dispensers | Universal. | Recommended by the manufacturer, sold in package |
⚠️ Warning: Do not use dishwashing liquids (e.g. Fairy or AOS under any circumstances, because their high foaming capacity will disable the fluid level sensor, and avoid alcohol-based perfumes, which can damage plastic parts.
Step-by-step instructions: how to fill the dispenser with soap
The refueling process is the same for most Xiaomi models, but there are nuances depending on the design. Consider the universal algorithm for the Mijia Automatic Soap Dispenser:
- Turn the device off the power. If the dispenser is running from the batteries, remove them. This will prevent the pump from accidentally operating during the filling.
- Remove the top cover. Most models have magnets or latches on it -- pull up with a little effort. The Viomi V1 has a counterclockwise lid.
- Remove the soap tank. In some dispensers, it's integrated into the housing -- then just open the filler hole.
- Wash the tank with warm water (if you refuel it) and remove the residue of old soap that can form clumps.
- Pour the soap to the "MAX" label. Don't go above the level, it will lead to leaks. Use the funnel or bottle nose for convenience.
- Set the tank in place and close the lid until you click. Make sure the sealing gum is flat.
- Turn on the dispenser and check the work. Press the sensor or hold your hand, and it should give you a soap.
🔧 Lifehack: If the soap is too thick, dilute it with distilled water in a 1:1 ratio, which will prolong the life of the pump and reduce the cost.
Disconnect power to the device
Prepare soap (dilute if necessary)
Wash the tank from the remnants of old soap
Check the integrity of the sealing gum
Pour the liquid strictly to the mark MAX-->
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when refueling dispensers, and here are the most common ones and ways to prevent them:
- 🚫 Soap overflow: If you pour a liquid above the MAX label, when you heat it up (like in a bathroom), it will expand and flow through the seals. Solution: always leave 5 to 10 mm of free space.
- 🧴 Use the wrong soap. Gel products or particle soaps (e.g. Safeguard with microbeads) clog the tubes. Solution: choose only liquid formulations without abrasives.
- 🔋 Refueling with power on. If the dispenser works during pouring, the soap can spill or get into electronic components. Solution: always turn off the device before refueling.
- 💧 Ignoring tank flushing, residues of old soap mix with new soap to form clots, solution: flush the tank with warm water every 2-3 refills.
⚠️ Warning: If the dispenser gives out soap in jerks or with a delay after refueling, it's likely that the tubes have become a traffic jam. To eliminate it, press the issue button 3-4 times in a row, this will pump the system.
What if the dispenser does not give out soap after refueling?
How to wash the meter Xiaomi: deep cleaning
Even with the right soap, deposits accumulate in the tubes and pump over time, and deep cleaning is recommended every 3-6 months (depending on the intensity of use).
- Prepare the solution: mix warm water (300 ml) with vinegar (50 ml) or citric acid (1 tsp) to dissolve the soap deposits.
- Put the solution in the tank instead of soap. Do not exceed the level of "MAX".
- Turn on the dispenser and press the issue button 10-15 times so that the solution passes through the entire system.
- Leave for 15-20 minutes, then repeat the issue 5-7 times.
- Rinse with clean water: pour water into the tank and pump the system until the foam stops going.
- Dry the device. Rub all available surfaces with a napkin and leave the lid open for 1-2 hours.
💡 Useful tip: If your dispenser has a removable pump (as in Viomi V1), remove it and rinse it under running water with a soft brush. Don't use metal objects - they can damage plastic parts.
💡
To disinfect the dispenser after cleaning, use a chlorhexidine solution (0.05%) put it in a tank, pump the system and leave it for 10 minutes, then rinse with water. This will kill bacteria that can accumulate in the tubes.
Comparison of models of dispensers Xiaomi: which is better to fill
Not all Xiaomi dispensers are the same, they differ in tank size, power type and soap compatibility, and in the table below we compare popular models:
| Model | Volume of the reservoir | Type of food | Features of refueling | Compatibility with soap |
|---|---|---|---|---|
| Xiaomi Mijia Automatic Soap Dispenser | 300 ml | 4 AAA batteries | Magnetic cover, removable tank. | Any liquid soap without abrasives |
| Viomi V1 | 400 ml | USB-C (or batteries) | Retractable cover, built-in pump | Original Viomi Soap Recommended |
| Xiaomi Youpin Smart Soap Dispenser | 250 ml | Battery 18650 | Removable tank, bay through the hole | Only low-viscosity fluids. |
| Aqara Smart Soap Dispenser | 350 ml | USB-C | Automatic pumping when switched on | Soap with pH 5.5-7.0 |
🔍 Conclusion: If you want a meter with minimal maintenance, choose a removable tank model (such as Mijia). For large families, a Viomi V1 with a volume of 400 ml is suitable. And if autonomy is important, look for battery devices (such as Youpin).
💡
USB-powered models (such as the Viomi V1) are more convenient to use because they don’t require battery replacement, but they are tied to a power bank or outlet, which limits installation space.
What to do if the dispenser stopped working after refueling
If after pouring soap the device does not give out liquid or works incorrectly, the reasons may be as follows:
- 🔌 Tubular clogs. Soap particles or dust block the passage of fluid. Solution: rinse the system with water and vinegar (see cleaning section).
- 🔋 Batteries are discharged. The pump doesn't have enough power to pump thick soap. Solution: replace the batteries.
- 💧 Air entering the pump. The air traffic jam interferes with normal operation. Solution: press the output button several times to blow the air.
- 🛠️ Pump failure: If the device makes unusual sounds (squeaking, squeaking), the gears may have broken, so you can call the service or replace the pump (if the model is repairable).
⚠️ Warning: If the dispenser starts spitting with soap or gives it out unevenly, check the sealing ring on the tank. Over time, it wears out and lets air through, which leads to malfunctions. Replace the ring (you can buy it in Xiaomi remakes on AliExpress).
🛒 Where to buy parts? Original seals, pumps and tanks for dispensers Xiaomi are sold on official sites:
- 🌍 Official Xiaomi website (Accessories section)
- 🛒 AliExpress (search for "Xiaomi soap dispenser parts")
- 🏬 Smart tech stores (e.g., "Svyaznoy", "M.Video")
Alternative ways to use the dispenser
Xiaomi dispensers are versatile, they can be adapted for different tasks, here are some non-obvious applications:
- 🧴 For lotion or cream, if you dilute the moisturizer with water to a liquid consistency, the dispenser will give you a portion of the product for the hands or face. Importantly, the cream should not contain oil!
- 🍯 For liquid honey or syrup, suitable for food plastic models (e.g. Viomi V1). Wash the device with boiling water before use.
- 🧼 For shampoo or conditioner, install a dispenser in the shower, which will make it easier to do so, and use only silicone-free shampoos (like Natura Siberica).
- 🎨 For liquid paints or inks, artists and designers use dispensers to accurately apply watercolor or carcass. Condition: the paint must be water-based.
⚠️ Warning: When using a dispenser for food fluids (honey, syrup), replace standard tubes with silicone tubes (sold in aquaristic stores). Plastics can release harmful substances.
💡
For experiments with alternative liquids, select a separate dispenser. Mixing different agents (for example, soap and lotion) leads to the formation of hard-to-remove deposits.
