What Xiaomi Dispensers Support Soap Replacement: A List of Models
Not all Xiaomi smart dispensers are reusable, for example, the budget Mijia Smart Soap Dispenser (Basic) models often come with disposable cartridges that canβt be refilled by themselves, while the flagship versions support removable tanks or refueling through the top hole.
Here is a list of the models that can replace soap:
- πΉ Xiaomi Mijia Smart Soap Dispenser Pro (with IR sensor, volume) 300/400 millimeter)
- πΉ Viomi Smart Soap Dispenser V1/V2 (Touch-sensitive, compatible with Mi Home)
- πΉ Soocare S1/S2 (auto-dosing)
- πΉ Xiaomi Youpin Smart Foam Dispenser (for foam, requires special soap)
- πΉ Mijia Smart Liquid Dispenser (2023) (voice-controlled Alice/Google Assistant)
If your model is not on this list, check the instruction or box for the Refillable label. Dispensable dispensers are usually labeled as Disposable.
Step-by-step: how to change soap in the Xiaomi dispenser
The soap replacement process varies depending on the type of tank: a removable cartridge or a built-in tank with a top pouring. Let's consider both options.
Option 1: Dispensers with removable cartridge (Mijia Pro, Viomi V2)
These models are equipped with special containers that are attached to the latches, so that they can be removed.
- Turn off the dispenser from power (take out the batteries or disconnect). USB-cable).
- Turn the device downwards (so that the soap does not spill out when removed).
- Press the cartridge locker (usually located on the side or bottom) and pull the container over yourself.
- Wash the old cartridge with warm water (if it is reusable) or install a new one.
- Pour the soap to the MAX label, avoiding air.
- Insert the cartridge back before the click and turn on the power.

β οΈ Warning: If the dispenser fails after replacement, check if the fluid level sensor is installed correctly. V2 It is located at the bottom of the cartridge and can be triggered falsely if the soap is foamy or too thick.
Option 2: Dispensers with built-in tank (Soocare S1, Mijia 2023)
So, here, the soap is poured directly into the body through the top hole.
- Remove the top cover (usually it unscrews counterclockwise or moves sideways).
- Remove the remnants of old soap with a funnel or syringe (donβt drain into the sink β it can clog the pipes!).
- Wash the tank with vinegar (1:1) if there is a plaque on the walls.
- Pour new soap through the funnel, avoiding spraying on sensors.
- Close the lid and turn on the dispenser. Wait for calibration (green light).
π‘ Lifehack: If the soap is too thick and doesn't pass through the pump well, dilute it with distilled water (10-15% of the volume) and prolong the life of the mechanism and reduce the consumption.
π‘
Before the first pour of the new soap, make a test run with water - this will help to check the tightness and operation of the pump without the risk of spoiling the consumables.
What soap is suitable for Xiaomi dispensers: requirements and recommendations
Not all liquid soaps are compatible with smart dispensers.
- π§Ό Consistency: Optimal viscosity is 1000β3,000 mPaΒ·s (like shampoo) too thick (like Dove in hard packaging) or liquid (Sanitelle hand soap) can cause the pump to fail.
- π§ Composition: without abrasive particles (scrabs) and aggressive surfactants (they corrode silicone seals).
- π pH neutrality: ideal range - 5.5-7.5. Acid or alkaline agents reduce the service life of the dispenser.
- πΏ Environmentally friendly: avoid microplastics soap - it clogs nozzles.
The table below shows proven brands and soap models that are suitable for Xiaomi dispensers:
| Brand | Model soap | Viscosity | Compatibility | Notes |
|---|---|---|---|---|
| Ecover | Zero Liquid Hand Soap | 2500 mPaΒ·s | β All models. | Eco-certified, without SLS |
| Fa | Schiuma Delicata (foam) | 1200 mPaΒ·s | β For foam dispensers | Requires a 1:1 dilution |
| Simple | Moisturizing liquid soap | 3000 mPaΒ·s | β οΈ Only for Mijia Pro | It can thicken at low temperature. |
| Xiaomi Youpin | Original soap for dispensers | 1800 mPaΒ·s | β All models. | Optimized for Viomi pumps |
β οΈ Note: Do not use shower gels (such as Nivea or Garnier) - their formula is designed to be flushed with water, not dosing through the pump. This will lead to clogging of the nozzles in 2-3 weeks.
Common mistakes when replacing soap and how to avoid them
Even experienced users sometimes make mistakes that lead to breakdowns or malfunctions in the dispenser. TOP-5 problems and solutions:
- The dispenser doesn't recognize the new soap. Reason: The fluid level sensor is dirty or the soap is too foamy. Solution: Wipe the sensor with a cotton swab dipped in alcohol. If the problem persists, replace the soap with a less frothy one.
- Leaks after cartridge replacement Reason: The cover is not tightly closed or the sealing gum is damaged Solution: Check the gum for cracks. If it is worn, order a replacement (Article for Mijia Pro: MDZ-06-DA).
- The pump works, but the soap doesn't work. The reason is: there's a traffic jam in the system or there's a blockage in the injector. Solution: Turn the dispenser over and knock lightly on the body. If it doesn't, rinse the nozzle with water under pressure.
π§ Secret trick: If the dispenser after replacing the soap gives an error E2 (Pump malfunction code, reset to factory settings, hold the power button for 10 seconds until the red light flashes.

How to care for a dispenser so that it lasts longer
The average life of a smart dispenser is 2-3 years, but with proper care it can be extended to 5 years.

- π Battery Replacement: Use only alkaline batteries AA (Cheap salt cells discharge quickly and can leak.
- π‘οΈ Temperature: Do not place the dispenser near heaters or under direct sunlight - this accelerates the evaporation of soap and degradation of seals.
- π οΈ Preventive inspection: every 3 months, check the condition of silicone pads and lubricate them with silicone lubricant (for example, WD-40 Specialist).
β οΈ Note: If you use a dispenser in a public place (office, cafe), set Eco Mode in the Mi Home settings. This will reduce soap consumption by 30% by reducing the serving from 1.2 ml to 0.8 ml.
