Modern automatic hygiene devices make daily life much easier by turning hand washing into a technological process. Xiaomi Mijia MJXSJ01XW has proven to be a reliable assistant, but many users face difficulties when trying to replenish supplies for the first time. Incorrect refueling can lead to clogging of the pump or a decrease in the quality of the foam jet, so it is important to follow a certain algorithm of actions.
In this article, we will discuss how to pour soap into the dispenser so that the device works long and stable. You will learn about the compatibility of various liquids, the peculiarities of mixing concentrates with water and the nuances of maintenance of the sensor system. Proper operation will prolong the life of the automatic dispense and preserve its aesthetic appearance.
Preparation of the dispenser for the first use
Before you start refueling, you need to properly prepare the container itself. The body of the device is made of durable plastic, but the internal mechanisms require careful handling. Unscrew the lower part of the tank counterclockwise, trying not to make excessive efforts to not damage the thread. If you are using the device for the first time, be sure to wash the container with warm water to remove dust or residue from factory tests.
A key element of the design is the pump system at the top of the lid, which is responsible for creating a thick foam. It is important to make sure that the fluid intake tube has no cracks and freely reaches the bottom of the container. Some users mistakenly try to pour soap without removing the top unit with electronics, which is strictly forbidden, since moisture can damage the touch contacts and the battery.
⚠️ Warning: Never submerge the top of the electronics and battery under water or a strong jet.
After washing, allow the tank to dry completely. The presence of excess water inside can change the concentration of the finished solution, making the foam too liquid. Make sure that the sealing ring on the neck of the bottle sits tight and is not damaged, otherwise leaks may occur during operation.
☑️ Pre-fueling check
Choosing the right soap and mixing proportions
One of the most common questions is what liquid to use. Xiaomi Mijia MJXSJ01XW dispenser is optimized for special foam formulations, but you can also use regular liquid soap if you dilute it correctly. The ideal proportion depends on the viscosity of the original product. For standard liquid soap, the ratio of 1 part soap to 5-7 parts water is recommended.
Using too thick a shower gel or shampoo without diluting it can break the micropump. The mechanism simply won't be able to push the viscous mass through a fine nozzle. If you use concentrates, read the instructions on the chemical manufacturer's packaging carefully. Often, to get the perfect foam, you need to add distilled or filtered water to avoid scaling inside the system.
- 🧴 Use only liquids without solids, scrubs or sequins that can clog the filter.
- 💧 Optimal water temperature for dilution – room, hot water can damage the reservoir plastic.
- 🌿 Alcohol-based antiseptics are permissible, but the alcohol concentration should not exceed 70% so as not to overdry the seals.
Experimentally, it's been shown that the best fit is a neutral pH, low foaming capacity, in its original form. It saturates the mixture with air, creating volume. If you pour the finished foam out of the cylinder, the device will not work, because the mechanism is designed to pump the liquid fraction.
💡
To check the readiness of the mixture, shake a closed tank: if large bubbles have formed that do not disappear for a long time, the solution is too concentrated and requires the addition of water.
Step-by-step: how to pour soap correctly
The refueling process takes no more than two minutes if you do all the steps in sequence. First, remove the top lid with the electronic unit, unscrew it or unplug it by turning it (depending on the modification of the mounting). Take the prepared soap solution and pour it carefully into the tank. Try to pour on the wall to minimize the foam inside the bottle before the device is turned on.
The fluid level should not exceed the MAX mark, if any, or reach the neck thread beginning. Leaving the air cushion is necessary to create the right pressure inside the tank. Once filled, tightly twist the top with the pump. Sharp twisting can squeeze some of the liquid through the tube, so do it smoothly.
| Type of instrument | Proportion (Soap: Water) | Recommendation |
|---|---|---|
| Special foam Xiaomi | Ready to use | Don't dilute |
| Ordinary liquid soap. | 1: 6 | Stir thoroughly |
| Antiseptic | 1: 4 | Check compatibility |
| Baby soap. | 1: 5 | Use filtered water |
Once the device is assembled, you need to start the system first. Press the reset button or just hold your hand to the sensor several times in a row. You'll hear the characteristic sound of the motor. The first 2-3 portions may be watery or contain air, which is the normal process of filling the supply line. Wait for a stable, elastic foam to appear.
Setting sensitivity and portion size
The MJXSJ01XW is often equipped with adjustable operating parameters, although they may be hidden externally. On some firmware versions or terdapat body modifications, the ability to change the volume of foam issued is done by (long press) the pairing button or through the Mijia application if the device supports Bluetooth connection.
The sensitivity of the infrared sensor is another important parameter. If the dispenser is triggered too early when you're just holding your hand, or vice versa, requires you to hold your palm close, calibration. This usually involves a combination of pressing the switch. Press the button 5 seconds before the indicator blinks, then quickly lift and remove your hand in the desired area.
⚠️ Warning: Do not attempt to adjust the mechanical valves inside the pump with screwdrivers or needles, this will result in depressurization and loss of warranty.
If you're using a device in a bathroom with mirrored surfaces, you should note that the IR sensor can respond to reflections, and if you're using it, you should change the angle of the meter a little bit, or you should wipe the area of the sensor away from condensation, and the purity of the sensor's "end" directly affects the reaction rate of the infrared receiver.
The secret of double-pressing
Problem Solving: Weak pressure and blockages
During operation, users may encounter a situation where the dispenser buzzes, but the foam does not go, or the jet becomes weak. Most often the reason lies in the drying of the soap in the output hole. The soap film solidifies and blocks the output. To fix the problem, remove the top and wipe the outlet with a moist warm cloth. You can also briefly lower the dispenser nose into warm water and turn on the supply.
Another common problem is suffocation, and if you've been out of the device for a long time or changed the temperature in the room abruptly, the tubes could become airborne, and then you can activate the sensor repeatedly (10-15 times) without interruption, and this will create the necessary pressure to pump fluid, and if the sound of the motor has changed and became quieter, the batteries may have run out, even if the indicator is still burning.
- 🔋 Replace the batteries with new alkaline if the device is powered by batteries AA.
- 🧼 Wash the fluid intake tube with warm water if thick soap was used.
- 🌡️ Do not store the dispenser in the direct sun or near the battery, heating reduces foam viscosity and gas pressure.
If nothing works, check the integrity of the silicone tube inside the case, it may have slipped or cracked, and if the tube is mechanically damaged, it can be replaced with a similar tube in diameter, matched at the aquaristics or parts store.
💡
90% of pressure problems are solved by simply washing the outlet with warm water and replacing batteries with fresh ones.
Device care and seasonal storage
Regular care is important for the longevity of the Xiaomi Mijia MJXSJ01XW. Every 2-3 months, or when changing the type of soap solution, it is recommended to completely empty the tank and wash it. Remains of old soap can sour or crystallize, which will adversely affect hygiene and the mechanism. Use soft detergents to clean the body itself, avoiding abrasive sponges.
If you are away for a long time and the device is not in use, it is best to leave it empty and dry.Storage with soap poured off for several months can lead to irreversible solidification of the solution in the pump.Remove the batteries if the device is self-contained to eliminate the risk of electrolyte leakage and corrosion of contacts.
Compliance with these simple rules will allow your smart dispenser to last for years, maintaining the initial efficiency of foaming. A smart home starts with cleanliness, and proper care of gadgets is the key to their smooth operation.
