What liquid soap is suitable for Xiaomi dispenser?
Not every liquid soap or hand gel is compatible with automatic dispensers. The manufacturer recommends using liquids with a viscosity of 100-500 mPa·s (millipascal-seconds) - this is roughly the consistency of a regular shampoo or liquid hand soap. Too thick gels (for example, for showers) or too liquid (diluted with water) can cause the mechanism to fail.
Here is what you should not put in the dispenser Xiaomi:
The best options are:
- 🧴 Liquid soap marked "for dispensers" (e.g. Dove, Palmolive, Safeguard).
- 🧼 Antibacterial gels without alcohol (for example, Lifebuoy in a bottle with a dispenser).
- 🌿 Natural soap bases (for example, Dr. Bronner's in diluted form).
Important: if you use homemade soap (for example, based on Castilian), its viscosity should not be higher than 300 mPa·s. You can check this with a simple test - turn the bottle over: the liquid should flow out in a smooth stream, and not drip or pour in a stream.
Preparation of the dispenser for the first refueling
Before you pour the soap, you need to assemble and prepare the device correctly. If you just took the dispenser out of the box, check the package:
- 📦 Main body with sensor.
- 🔋 Battery bay (or battery if the model is wireless).
- 🧴 Removable liquid tank.
- 🔧 Fixed elements (if the dispenser is wall-mounted).
- 📑 Instructions (often with QR-code for the Mi Home app).
Follow the steps:
- Install batteries (usually 4) × AA) or charge the battery (if the Viomi model) V3 Pro USB-C).
- Remove the top cover of the tank by pulling it up (on some models you need to press the latch).
- Wash the tank with warm water (no detergents!) and dry it. This will remove any dust from the production.
- Check the silicone pad at the bottom of the tank – it should be whole and fit tightly.

If your dispenser has been used before, be sure to wash the system before a new refueling:
- Put warm water in the tank (without soap!).
- Press the issue button 3-5 times to allow water to pass through the pump.
- Repeat the procedure 2-3 times, then dry the dispenser for 1-2 hours.

If the dispenser makes strange sounds when working (squeaking, crackling), most likely, dirt has fallen into the mechanism.
Step-by-step: how to pour soap into the dispenser Xiaomi
Now, to the main thing, which is to refuel, it's important to do this carefully to avoid leaks and traffic jams.
Step 1. Prepare the soap.
- If you use soap from a new bottle, shake it to prevent stratification.
- If the soap is too thick, dilute it with distilled water (no more than 10% of the volume).
- Do not pour soap directly from the bottle - use a measuring glass or funnel to avoid spills.
Step 2. Fill the tank.
- Remove the tank cover (on some models you need to turn it counterclockwise).
- Pour the soap to the mark MAX (It's usually 250 to 300 ml. Don't overdose!
- Close the lid and make sure it is tightly fixed (the click should be heard).
Step 3. Remove the air traffic jams
- Put the dispenser on a flat surface.
- Press the issue button 2-3 times until the soap foam appears, which means that the air has left the system.
- If the soap is not coming, slightly tilt the dispenser forward and press again.
Step 4. Check the work.
- Put your hand in front of the sensor (5-10 cm).
- The dispenser should give a portion of soap in 0.5-1 seconds.
- If the output is intermittent or too plentiful, adjust the settings in the Mi Home app (if the model supports connection).
