Modern home gadgets are becoming more popular, and automatic dispensers from Xiaomi are occupying a leading position in this segment, users appreciate them for their stylish minimalist design that fits into any interior, as well as for the hygiene of use. However, after buying in the store, many are faced with the question of how to properly assemble the device so that it works correctly.
The initial installation process does not require special tools or deep technical knowledge, but has its nuances. Incorrect cartridge installation or disruption of the sequence of actions can lead to leaks or breakage of the fluid supply mechanism. In this guide, we will discuss each step in detail so that your smart dispenser lasts long and without complaints.
So let's look at both liquid soap and water models, because they work in a similar way, but they may have different designs, and it's important to look carefully before you start and make sure all the components are in place, and just starting right will ensure that the sensor is running smoothly and there's no problem in the future.
Accommodation and preparation of the workplace
Before you start assembly, you need to unpack the box and spread all the components on a clean, flat surface. Usually the kit comes with the dispenser body itself, a liquid container (or replaceable cartridge), instructions in Chinese or English, and power supplies. Make sure that the body does not have visible damage, cracks or chips that may have occurred during transportation.
Special attention should be paid to the contact areas inside the battery compartment. They should be clean and dry. If you plan to attach the device to the wall, prepare a drill or screwdriver in advance, although most users prefer desktop accommodation. You will only need a few minutes of free time and good lighting to work.
- 📦 The main unit of the dispenser with a sensor and pump
- 💧 Liquid container (reservoir)
- 🔋 Batteries like this. AA (Often 4 pieces, sometimes come in the kit)
- 📄 Instructions and warranty card
- 🧱 Fixing elements (for wall installation, if provided)
⚠️ Warning: Before assembly, be sure to wipe the inside of the tank with a dry cloth if there is dust or industrial debris.
Installation of the batteries
The first and most important step is to install power sources. Most Xiaomi Mijia models are powered by four AA batteries, and the compartment is usually located at the bottom of the device or at the back, with a decorative cover, and it is important to observe polarity when installing, focusing on the circuits applied inside the compartment.
Use only high-quality alkaline batteries, as they provide the stable voltage required to operate the pump motor. Cheap salt analogues can quickly discharge or do not start the fluid supply mechanism the first time. Once installed, the lid should snap with a characteristic click, ensuring tightness.
Once power is installed, the front indicator may flash, signaling readiness to work. If this does not happen, check the density of the contacts. Sometimes you need to slightly rotate the batteries in the sockets to move the oxide film and ensure reliable contact.
Installation of the tank and cartridge
The next step is to install a soap or water tank, and depending on the model, it could be a separate transparent tank that is inserted into the case, or a ready-made replacement cartridge. If you use a model with interchangeable blocks, just insert a new cartridge into the socket to the end. You should hear the click of the locking mechanism.
For models with reusable tanks, the process is slightly more complicated: you need to unscrew the top (the pump unit) counterclockwise, then gently pour the liquid into the container. It is critical not to transfuse the liquid above the MAX mark, because when you twist the lid, the level will rise, and the excess soap will flow out, getting into the electronic part of the device.
| Type of model | The volume of the reservoir | Type of liquid | Feature of the installation |
|---|---|---|---|
| Xiaomi Mijia Auto | 300 ml | Liquid soap | Replacement cartridge or filler |
| Xiaoda Foam | 250 ml | foam | Just the finished foam. |
| Smart Water Dispenser | Large volume | Water. | The tube sinks to the bottom. |
| Pro version | 350 ml | Gel/Soap | Adjustment of portion size |
When you twist the pump, don't put too much effort into it. The plastic can crack if you overdo it. Twistle until you have resistance, then press it slightly. Make sure the fluid intake tube is lowered to the bottom of the tank and not bent.
Setting up the sensor
After physical assembly, the device must be activated. Many models activate the touch sensor automatically when the batteries are first installed. However, some versions require a double press on the power button located on the back or bottom of the case.
The light indicator usually changes color or starts to burn with a smooth light, confirming a successful start. If the indicator flashes red, this may indicate a low battery charge or improper installation of the cartridge, in which case it is worth rechecking all connections and replacing the batteries with new ones.
☑️ Checking the dispenser's readiness
Some advanced models allow you to adjust the sensitivity of the sensor or the amount of portions you give out, either through the Mi Home app or by a combination of clicks on the control button, and the standard setting is suitable for most bathroom or kitchen use cases.
First start-up and testing
Before you start using the device, you need to do a few test taps, put your hand under the sensor and wait for the foam or water to flow. The first 2-3 servings can contain air, as the system takes time to fill the tubes and create the necessary pressure.
Notice the consistency of the foam you're going to be using. If it's too liquid or too thick, you might need to adjust the ratio of water to soap (concentrate models) or change the cartridge to another type. For models that use soap, the viscosity of the liquid is important.
⚠️ Warning: If after a few presses the liquid does not come in, do not keep your hand under the sensor constantly. 10-15 Seconds to avoid overheating of the motor.
Check the sealed connection of the tank to the main unit, run a dry wipe along the junction of parts after several cycles of work, if the napkin is dry, then the assembly is done correctly and there are no leaks.
Wall mounting and placement
Although the dispenser is conveniently placed on the table, many prefer to attach it to the wall to save space and a more aesthetic appearance.The kit often comes with bilateral tape or a template for drilling.Be sure to degrease the wall surface with alcohol or a special tool before sticking the tape.
Choose a place that is protected from direct jets of water if the device does not have a high class of moisture protection. Constant water intake on the touch unit can lead to false positives or corrosion of contacts. The optimal height of the placement is 15-20 cm from the edge of the sink.
How do you remove a sticker without a trace?
If you use a model with a large tank, make sure that the wall will withstand the weight of the full device. In case of doubt, it is better to use a mechanical mount on the dowel, not just an adhesive base, this ensures that the dispenser does not fall at the most inopportune moment.
Maintenance and replacement of consumables
For long-term service, you need to change your consumables in a timely manner. A low fluid level signal is usually a flashing indicator or a change in the color of the glow. You should not wait for a full emptiness of the tank, since the pump's operation on the dry can cause it to fail.
Regularly wipe the nose of the dispenser with a wet cloth. dried residues of soap can clog the outlet, which will lead to the spray of liquid to the sides instead of a flat stream or foam. Once a month, it is recommended to wipe the touch window with a soft dry cloth to maintain sensitivity.
- 🧼 Change the cartridge immediately after the liquid is exhausted.
- 💧 Use only the recommended types of liquids
- 🧽 Wash your nose from dried foam weekly
- 🔋 Replace batteries at the first discharge signal
💡
If you use a reusable tank and plan to stay away from the dispenser for a long time (for example, going on vacation), it is better to rinse the system with water and leave the pump dry, which will prevent the soap from drying out inside the mechanism.
When replacing the cartridge, always use original or certified compatible consumables. Cheap analogues can have a different viscosity, which will disrupt the metering mechanism and lead to rapid wear of the pump gears.
Possible problems and solutions
Even with proper assembly, there can be minor nuances in operation: If the dispenser has stopped responding to the hand, try to wipe the sensor or replace the batteries. Sometimes the problem lies in the oxidation of the contacts, especially if the device is in a room with high humidity.
If the pump is buzzing but the fluid is not flowing, check if it is out and there is no air plug in the tube. You can try several times to quickly put and remove your hand from the sensor to start the pumping mechanism. In rare cases, you need to reset the settings to the factory.
⚠️ Warning: Do not disassemble the sealed pump unit yourself. There are (precise) mechanisms inside, and a leakage disorder will make it impossible to create a vacuum to lift the fluid.
If you have a bug that you can't fix with standard methods, you can go to a service center. You can't be guaranteed to repair complex electronics yourself. Remember, good operation is the key to a long life for your smart assistant.
