How to Add Soap to Xiaomi Dispenser

Owning the Xiaomi Mi Home ecosystem is comforting, but even a smart home requires basic maintenance, such as regular refueling of consumables. The question of how to add soap to Xiaomi’s dispenser often arises for new owners who are faced with the design features of the device. Despite the apparent simplicity, the process of replacing the container or adding liquid has its own technical nuances, ignoring which can lead to failure of the mechanism.

Modern automatic dispensers, whether the Yijian or the classic Mijia, operate on the principle of infrared induction. This means that inside the body there are sensitive electronics and pumps that do not tolerate moisture on the contacts. The tightness of the system is a key factor in the long service of the gadget. Assembly errors often lead to leaks that can disable not only the dispenser itself, but also damage the surface on which it is standing.

In this article, we will discuss in detail the algorithm of actions for different modifications of dispensers, you will learn what types of soaps are suitable for use, how to avoid the formation of air traffic jams in the feed system and what to do if the device ceases to respond to commands, proper operation will ensure stable sensor operation and uniform supply of foam.

Design features of smart dispensers

Before you start replacing content, you need to understand what kind of device you're dealing with. Xiaomi's product line includes several generations of dispensers that can differ significantly in the way the case is opened. Most models have a hidden locking mechanism that is not obvious on first inspection. Mechanical force is not applicable here - trying to tear the lid by force will break the plastic latches.

The classic Mijia Automatic Foam Soap Dispenser (often called the white cylinder) opens by turning the top counterclockwise. It's a standard threaded mechanism that many people know from regular bottles. However, newer versions, such as the Yijian or specialized kitchen models, can use clips or magnetic mounts. It's important to determine the type of mount before you start active actions.

Inside the case, there's a removable cartridge or pump tank. The pump is the heart of the device, it creates pressure to squeeze out the soap foam. In some models, the pump is built into the lid, in others it's part of the removable unit. The understanding of this difference is critical: if you buy a refill package (replaceable container), you don't have to wash the old bottle, you just change it completely.

⚠️ Warning: Never attempt to open the bottom of the case where the batteries are located until the top with the tank is removed.Attempting to access the power compartment under load or in the presence of spilled liquid can cause a short circuit.

Preparation for refueling: choice of detergent

One of the most common questions is what to refill the device with. Manufacturers often recommend the use of original replacement units, but the cost can be high for daily use. Can you use regular liquid soap? The answer lies in the viscosity and chemical composition of the liquid.

Xiaomi's automatic dispensers are designed to handle fluids of a certain density. Too thick soap will put excessive pressure on the pump motor, which will overheat and quickly fail. Too liquid (like water) can flow through the valves or not foam properly. The optimal solution is to use specialized tools for auto-dispensers or dilute conventional soap.

If you decide to prepare the solution yourself, you will need:

• 💧 Liquid soap or shower gel (preferably without large abrasive particles and scrubbing elements).
• 💧 Distilled or boiled water (to prevent scale formation on the mechanism).
• 💧 A measuring cup to comply with proportions.

The ideal ratio for most models is 1 part soap to 3-4 parts water, which provides the necessary foam and ease of passage through the nozzle. Mix the solution carefully until you get a homogeneous mass. The presence of air bubbles in the mixture before pouring is undesirable, let the solution settle for 10-15 minutes.

💡

Use only distilled water to dilute soap. Tap water contains calcium salts, which over time form a white coating inside the pump's thin tubes, which can block the flow of fluid.

Step-by-step: cartridge replacement and refueling

The process of replacing the content depends on the type of device you have, and let's look at two basic scenarios: replacing the refill and manually refilling the existing tank, both of which are the clean hands and the work surface.

For interchangeable block models (e.g. some Yijian versions):

1. Remove the top cover-dispenser from the base if it is required by the design (sometimes the entire unit is changed).
2. Remove the empty cartridge from the case.
3. Insert a new one, first removing the protective membrane from it (if any).
4. Install the block back into the case before the characteristic click.

For the classic Mijia model with manual refueling:

1. Take the body of the dispenser with one hand for the base, and the second firmly embrace the upper cover.
2. Start turning the lid counterclockwise. Don't be afraid to make a moderate effort, but avoid jerking.
3. After unscrewing the thread, gently pull the lid up. Remove the fluid intake tube from the bottle neck.
4. Wash the inner container with warm water if there are remnants of old soap left in it to avoid drying and forming traffic jams.
5. Pour the prepared solution or insert a new original bottle.
6. Put the tube back in, ensuring it reaches the bottom, and twist the lid clockwise to the point.

System pumping and initial start-up

Once the device is assembled, it often happens that the indicator lights up but the soap is not supplied. This is a normal phenomenon, due to the fact that there is air in the tube and the pump chamber. The device must be pumped. To do this, place your palm under the nose of the dispenser and press the touch button (or hold your hand if the mode is automatic) several times in a row.

It is usually required 3 before 10 press the air out and the foam starts. 15-20 No pressing, check a few things. First, make sure the fluid intake tube is lowered to the bottom of the tank and doesn't hang around in the air. Second, check if the tube is twisted when it's assembled. Third, make sure the lid is twisted to the end – many models have a protective mechanism that blocks the pump from working when it is not tightly closed.

The table below shows the main symptoms and ways to eliminate them during the start-up phase:

Set up through the Mi Home app

Xiaomi’s smart dispensers often support connectivity to the Mi Home ecosystem. This opens up additional control options. To connect, press and hold the button on the body (or press two buttons at the same time, depending on the model) for 5 seconds until the indicator flashes blue. This activates the pairing mode.

In the smartphone app, click "+" and select the device you find. Once connected, you can:

• 📱 Tracking the battery level in real time.
• 📱 Adjust the volume of one serving of extruded soap (saving mode or standard).
• 📱 Receive notifications about the need to replace the cartridge or low fluid level (in models with a level sensor).

Sometimes you have to reset the device to factory settings, which usually requires you to press the button for 10-15 seconds before changing the color of the indicator, which is useful if the dispenser has stopped responding to commands or lost communication with the router.

⚠️ Note: When you reset or reconnect to a new Wi-Fi router (especially if you change your password or network name), the device will need to be reconfigured. Make sure your smartphone is connected to a 2.4 GHz network, as Xiaomi smart home devices often do not support 5 GHz networks.

Maintenance and care

To ensure the durability of the device, it is recommended to carry out preventive cleaning every 2-3 months, even if you use replaceable blocks. The accumulation of soapstone and bacteria inside the tubes can worsen the hygienic properties of the dispenser. Once a quarter, completely empty the tank and rinse it with warm water with citric acid.

Citric acid is a great dissolution of limestone, which is inevitably formed when using aqueous solutions. Pour a weak solution of acid into the tank, let it stand for 20 minutes, then thoroughly rinse with clean water. Pay special attention to the nozzle dispenser, which is where blockages form most often.

Also, monitor battery health. Use only high-quality alkaline cells. Cheap salt batteries can leak and oxidize contacts, causing permanent damage to the electronic board. If you go on vacation for a long time, remove the batteries from the device.

💡

Regular washing of the system with warm water prevents 90% of all possible breakdowns associated with clogging of the pump and supply tubes.
