How to properly refill Xiaomi dispenser: from soap to car-drinker

Modern Xiaomi ecosystem devices are designed to automate everyday processes, making them more hygienic and convenient. One of these gadgets is an automatic dispenser, which is most often associated with a liquid soap dispenser, but can also be presented as a smart car washing for animals. Proper operation of these devices requires understanding their design features, because simply replacing content here is not always the only action. Owners need to know not only the sequence of the assembly, but also the nuances of the sensors that control the supply of the substance.

Errors in initial setup or maintenance can cause the device to stop responding to commands, leak or give out an incorrect portion volume. For example, in soap models it is critical not to damage the fluid intake tube, and in bottles to ensure that the system is tight so that water does not flow naturally. In this article, we will detail the algorithms for different types of devices of the brand, paying special attention to technical points that are often overlooked.

It's worth noting that the control interface and physical design can vary significantly depending on the model. There are versions with a mechanical button, with an infrared motion sensor and fully automatic systems with a connection to a smartphone. Understanding how your particular device works is the key to its long service. Next, we will look at general rules and specific instructions that will help avoid common problems in operation.

Preparation for device maintenance

Before you start replacing the contents, you need to do a number of preparatory operations, both for hygiene dispensers and for drinking water. Hygienic cleanliness of the tank is a priority, because bacteria can multiply in the residue of the old liquid, which then get into a new portion of the product. If you use the device for the first time after buying, wash all removable parts with warm water without using aggressive chemicals.

It is important to make sure that the device is completely dry on the outside, especially in the area of contacts and sensors. Wet hands or drops of water on the case can cause false alarm or short circuit in electronics. Use soft, fuzzy fabric to wipe, which will not leave fibers on the surface of the plastic.

⚠️ Warning: Never immerse the main electronics and battery unit in water, wipe it with a slightly wet wipe, remove the power sources first.

If you plan to use a non-original product, make sure that its viscosity meets the manufacturer's requirements. Too thick liquid can create excessive pressure in the system or clog thin feed channels, which will lead to a breakdown of the pump. Compatibility check is a mandatory stage of preparation.

Refilling the automatic soap dispenser

The soap replacement process in the Mijia Automatic Foaming Hand Washer series has its own characteristics that distinguish them from conventional mechanical vials. The main difficulty is the design of the neck and the presence of a special valve that prevents foam from leaking when rolling over. To fill the device, you need to remove the upper cover with the mechanism and unscrew or pull (depending on the model) the tank.

There are two main ways to refuel: using the original replacement units or refueling your own product. In the first case, you simply insert a new sealed bottle into the case. In the second, you need to carefully remove the meter spout from the used container, wash it and pour new liquid. It is important not to transfuse the product above the MAX mark, if any, or to the level of the shoulders of the vial.

Once the container is filled, you need to put the fluid intake tube in place, it should be able to go down freely to the bottom, but not to rest with force so as not to deform. Then carefully screw the dispenser mechanism around the neck of the bottle, the thread should be twisted easily, without the use of excessive force that can tear the plastic fastener.

Setting up portions and operation of sensors

After the physical installation of the container, you need to adjust the device. In most Xiaomi models, this is done through prolonged pressing of a button or a combination of actions. For example, to switch the foam feed mode (normal or economy), you may need to press the button five times in a row, after which the indicator will flash a certain color.

Sensors on the front require cleanliness. Fat spots from the hands or sprays of soap can block infrared radiation, which will stop the dispenser from "seeing" the hand. Regularly wipe the sensor area with dry cloth. If the device is powered by batteries, their charge also affects the pump power: when the elements are discharged, the foam can be too liquid or the supply will stop altogether.

💡

Use only medium-viscosity liquid soap. Shower gels or shampoos may be too dense for a soap foam pump, causing rapid wear and tear.

Some advanced models allow you to control settings through the Mijia app, where you can set the portion size, turn on sterilization mode (if you have a UV lamp), or check the battery level. Connection to the smartphone is via Bluetooth, so the phone must be in close proximity to the device during the setup.

Refueling a smart car wash for animals

Special attention should be paid to pet devices such as Xiaomi Smart Pet Water Fountain, which differ from soap dispensers, using a water circulation system with filtration, and filling such dispenser involves not only water replenishment, but also maintenance of the filter element.

The process is this: first, you take the pump out of the tank, then you remove the top bowl, you pour fresh water inside the main tank, you use filtered or settled water to minimize scale on the heating elements and the pump, and the water level must be above the minimum, otherwise the pump can run dry and burn.

• 🐾 Remove the old filter and install a new one, pre-soaking it in water on the water. 5-10 charcoal-activating.
• 🐾 Collect the design in reverse order, making sure that all sealing rubbers are in their places.
• 🐾 Connect the device to the network and press the on button; the indicator should light up in blue.

In models with boiling function (thermo-drinking), the process can take longer, as the device first heats the water to a safe temperature, and then cools it. Do not try to open the lid or add water during the heating cycle - this will disrupt the temperature regime.

Table of compatibility of liquids and means

Not all products are suitable for use in automatic dispensers. Incorrect chemical choices can lead to corrosion of the internal parts, clogging of nozzles or the formation of too thick foam that the device can not squeeze out. Below is a table that helps determine the suitability of various types of products.

If you decide to experiment with folk remedies or homemade solutions, be aware of the risks: abrasive particles in scrubs or solid soap chips are strictly forbidden - they act as sandpaper for pump mechanisms.

Remediation and cleaning

In the process of operation, there may be situations when the device stops supplying liquid or does it intermittently, most often due to a clogged outlet or an air plug in the tube. To eliminate the air traffic jam, you can press the feed button several times, holding the device above the sink until a stable stream goes.

Cleaning the nose of the dispenser is a regular procedure. Withered soap forms a crust that prevents the foam from coming out. Remove the top spray lid and rinse it under hot water. Use a soft brush (like an old toothbrush) to remove plaque from hard-to-reach areas.

If the pump is buzzing but the liquid is not flowing, check the contents and position of the tube. Sometimes the tube is disconnected from the connection inside the tank, in such cases, you need to disassemble the container, correct the connection and check the leakage.

⚠️ Warning: If you smell a burn or heat the case, immediately remove the batteries or disconnect the device from the network.
