Xiaomi’s automatic liquid soap dispensers are popular devices in the smart home line that save cleaning costs and make hygiene procedures more convenient. However, many users face the problem that concentrated soap or hand gel is too thick for the dispenser mechanism, leading to nozzles clogging, uneven feeding or even pump breakdown. Dilution is a key step in preparation, but it is important to balance: too liquid solution will foam poorly, and too thick will clog the system.
In this article, we will analyze how to properly dilute liquid soap for Xiaomi dispensers (including Mijia Smart Soap Dispenser, Viomi and others), what proportions to use for different types of products (antibacterial gels, baby soap, shampoos), and also reveal the nuances of device care. We will pay special attention to typical errors that reduce the life of the dispenser, and give recommendations for the choice of detergents compatible with Xiaomi equipment.
Why you need to dilute the soap for Xiaomi Dispenser
Xiaomi's automatic dispensers are designed to work with liquids of a certain viscosity. The manufacturer indicates that the optimal consistency of the product should resemble water with a small amount of honey - not too thick, but not completely liquid.
- 🔧 Blockage prevention: The thick soap clogs the microscopic holes of the nozzle, causing the dispenser to spit or stop dispensing at all.
- ⚡ Reduced pump load: Viscous fluids cause the motor to run at power limit, leading to overheating and shorter lifespan.
- 💧 Savings: Diluted soap is more easily dosed, which means that the serving per press will be stable (usually 0.5-1 ml).
- 🧼 Better foaming: Concentrated gels foam poorly when in contact with water, and diluted gels create abundant foam at the first wave of the hands.
Moreover, the instructions for Xiaomi Mijia and Viomi dispensers explicitly state that the use of undiluted gels voids the warranty, and the manufacturer recommends diluting even those products that are labeled “suitable for automatic dispensers” – often their viscosity still exceeds the permissible limits.
What can be diluted: compatibility with Xiaomi
Not all detergents are suitable for automatic dispensers, but here are the criteria for choosing:
| Type of instrument | Compatibility | Recommendations |
|---|---|---|
| Liquid toilet soap (e.g. Dove, Fa) | ✅ Yes. | Dilute with water in a ratio of 1: 1 or 1: 1.5. Avoid products with large abrasive particles (scrabs). |
| Antibacterial gels (e.g. Sanitelle, Schwarzkopf) | ✅ Yes (with reservations) | Dilute strictly distilled water (1:2). Alcohol in the composition can damage plastic parts. |
| Baby soap without fragrance | ✅ Yes. | The best option is to dilute 1:1.5. Hypoallergenic composition is safe for the mechanism. |
| Shampoos and shower gels | ⚠️ Conditionally. | Only if the package says "suitable for dispensers." Dilute 1:2, but watch for foaming. |
| Concentrated detergents (e.g. Fairy) | ❌ No. | Too aggressive, could break the seals and cause leaks. |
What can not be poured into the Xiaomi dispenser:
- 🚫 Means with abrasive particles (scrabs, peels).
- 🚫 High alcohol gels (>10%).
- 🚫 Body oils or cream soap.
- 🚫 Liquids with insoluble additives (e.g., sequins).
⚠️ Warning: If the product is labeled "do not dilute" or "manual use only" on the packaging, it cannot be filled into a Xiaomi dispenser. This can cause the pump to break and leaks.
Optimal proportions for dilution: table by soap type
The proportions of water and soap depend on the original viscosity of the product. Below is a universal table, tested on the Xiaomi Mijia Smart Soap Dispenser and Viomi Smart Soap Dispenser:
| Type of soap/gel | Proportion (soap:water) | Recommended water | Notes |
|---|---|---|---|
| Dense toilet soap (such as Palmolive) | 1:1.5 | Boiled or distilled | If the product is still thick after dilution, add another 10% of water. |
| Antibacterial gel (e.g., Sanitelle) | 1:2 | Only distilled | Alcohol in the composition can react with impurities in tap water. |
| Baby soap (e.g. Johnson's Baby) | 1:1 | Boiled. | Less aggressive composition, you can dilute less. |
| Liquid soap marked "for dispensers" | 1:0.5 | Any clean one. | It’s usually already optimized, but it can be too thick for Xiaomi. |
| Shampoo 2-in-1 | 1:2.5 | Distilled | It requires careful mixing, otherwise it will be stratified. |
Critically, for antibacterial gels with an alcohol content of >5%, use only distilled water. Impurities in tap water (chlorine, salt) can react with alcohol and form a precipitate that will clog the mechanism.
How do you check the viscosity after dilution? Drop it on a clean surface -- if the droplet spreads slowly (at the speed of honey), the consistency is good. If it spreads too quickly, add a little soap, if it doesn't spread out, water.
Select a compatible tool (see table above)|
Measure the right amount of soap and water (use a measuring glass)|
Mix in a separate container, avoiding lumps |
Allow 10-15 minutes to stand still to remove air bubbles |
Filter through gauze (optional, to remove undissolved particles)|
Pour into the dispenser through the funnel, avoiding the straits-->
Step-by-step: how to dilute and pour soap
The process of diluting and refilling the dispenser consists of several steps, follow them strictly to avoid errors:
- Preparation of ingredients. You'll need: 🧴 Liquid soap or gel (check compatibility in the table above). 💧 Water (boiled, filtered or distilled). 🥄 Measured glass or spoon. 🔄 A clean stirring stick (e.g., a wooden skewer). 🧻 Gauze or a small sieve (optionally, for filtration).
- Mix. In a separate container, mix the soap and water in the right proportion (see table). Stir slowly, avoid foaming. If there are lumps, strain through the gauze.
- Standing. Let the mixture stand for 10-15 minutes. This is for: 🫧 Air bubbles (which can cause unstable pump operation). 🔍 Separation checks (if the water and soap are separated, mix again).
Fill the tank carefully through the funnel. Don't add it to the top, leave 5 to 10 mm of free space to avoid leaks when the pump is running.
Checking. Press the sensor or the dispenser button 2-3 times to blow air out of the system. The first portions can be unstable, that's normal.
💡
If the dispenser gives out soap in jerks or bubbles after refueling, then there is air in the system. To remove it, press the dosing button 5-6 times in a row, directing the jet into the sink.
Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when diluting the soap, which leads to breakages or malfunctioning of the dispenser, and here are the most common mistakes and ways to prevent them:
- 🌊 Using tap water without preparation. Chlorine and salts form a sludge that clogs the nozzle. Always boil water or use distilled water.
- 🌀 Insufficient mixing. If the soap and water are mixed poorly, the tank will form layers of different viscosity, and the pump will choke. Stir for at least 2-3 minutes.
- 🔥 Filling hot soap. Some users dilute the soap with hot water for better dissolution, which is a mistake. When cooled, the viscosity will change, and the product will become too thick.
- 🧴 Mixing different types of soaps, like antibacterial gel + baby soap, can cause a chemical reaction and produce flakes.
- 🚰 Reservoir overflow. If you pour soap under the lid, the pump will leak out through the vents.
⚠️ Warning: If after refueling, the dispenser starts to sneeze (the soap is not dispensed uniformly), there are likely air bubbles left in the system. Don't try to disassemble the device - just press the dispenser several times, directing the jet into the sink until the supply stabilizes.
What if the dispenser stopped working after refueling?
How to care for Xiaomi Dispenser: extend the service life
Regular maintenance of the device prevents blockages and breakdowns.
- 🧽 Weekly cleaning. Rub the body and touchpad with a wet wipe. Avoid abrasives.
- 🔄 Flush the system. Once a month, pour clean water into the tank and pump it through the pump 10 to 15 times.
- 🔋 Battery control: If the dispenser is battery-operated, replace them at the first sign of discharge (weak jet, reaction delays).
- 🌡️ Temperature: Do not place the device near heat sources (e.g., over the washing machine). The optimum temperature is 10-35°C.
- 🚫 Moisture protection: Despite moisture protection, avoid direct water ingress to electronic components.
💡
Use only original parts and accessories for Xiaomi dispensers. Non-original tanks or covers may not fit tightly, which will lead to leaks.
If the dispenser is not used for a long time (for example, during vacation), drain the soap out of it, rinse the tank with water and leave it to dry disassembled, this will prevent the residues from drying out in the pump.
Alternative ways to refuel: what to do if the soap is too thick
Sometimes even after dilution, the soap is too viscous for the dispenser, and in these cases, alternative methods can be used:
- Adding glycerol. 1-2 drops of pharmacy glycerol per 100 ml of the mixture will make the soap more fluid without losing detergent properties. Do not exceed the dosage - excess glycerol can cause stickiness.
- Heat the mixture. Heat the water to dilute to 40-50°C (not higher!). Warm water dissolves thick gels better. Cool the mixture before refueling.
- Special solvents: Some manufacturers (e.g. Ecover) produce liquids to dilute concentrated detergents. They are safe for the machine.
- Replace soap with powder. In extreme cases, you can dissolve baby soap in a bar in water (grate and stir), the proportion is 1 tbsp. spoon of shavings per 200 ml of water.
Important: Never use for dilution:
- 🚫 Alcohol or vodka (corrodes plastic).
- 🚫 Vinegar or citric acid (corrodes metal parts).
- 🚫 Mineral water (salts will clog the nozzle).
