Owning the Xiaomi Smart Home ecosystem opens up many possibilities for automation of everyday life, and one of the most popular gadgets has long been an automatic dispenser for soap. This device not only looks stylish and futuristic, but also provides a high level of hygiene, allowing you to wash your hands without touching the case. However, like any consumable, soapy liquid tends to run out, and before the user the question of the correct replacement of the content.
Many owners face a dilemma: buy original cartridges, which often have to wait from abroad, or adapt the dispenser to affordable household products. The replacement process seems simple, but has its own technical nuances, ignoring which can lead to a failure of the pump or clog the foam supply system. In this article, we will discuss in detail how to replenish stocks, than refuel the device and what to do if it stops working after maintenance.
Incorrect operation or use of inappropriate fluids can irrevocably damage the dispenser mechanism, so it is important to follow the algorithm of actions. We will look at the features of various models, including popular versions of Mijia Auto Induction and newer modifications with fluid level sensors. Understanding the device’s operation will help you avoid common errors and extend the life of the gadget.
Design of a smart dispenser and types of cartridges
Before you start replacing, you need to clearly understand what device you are dealing with. The bulk of the dispensers Xiaomi is built on a modular principle: in the plastic case is a power supply with electronics and motor, and at the bottom is attached interchangeable cartridge with soap.
Original cartridges often have a chip or mechanical meter that tells the Mijia app about the fluid residue, but the electronics of the dispenser are shown to respond primarily to the presence of a physical obstruction (liquid) and pump operation, rather than to digital readings of the capacity, which allows you to successfully use reusable adapters or refill native vials.
There are two main types of neck design: standard screw and regional specific. In some cases, users buy dispensers designed for the Chinese market, where the thread may differ from European counterparts. Visual inspection of the bottom of the device before buying replacement units is a mandatory procedure.
Preparation for replacement: necessary tools and materials
The soap replacement process doesn't require complex equipment, but having certain items on hand will make the procedure quick and clean. You won't need screwdrivers or tweezers, because the entire design is designed for user service without tools. The main thing is to prepare a workplace where the spilled liquid will not spoil the furniture.
For a successful operation, you will need:
- 🧴 New soap container or original Xiaomi cartridge.
- 💧 Distilled or boiled water for diluting concentrate.
- 🧻 Paper towels or napkins to remove spilled liquid.
- 🧼 Liquid soap with neutral pH (preferably without scrubbing particles).
Special attention should be paid to the choice of the detergent itself. The viscosity of the liquid is a critical parameter. Too thick soap (often found in cheap brands) will be difficult to pass through narrow pump channels, which will lead to rapid discharge of batteries and eventual failure of the mechanism. The ideal consistency resembles a liquid shower gel or slightly denser water.
If you plan to use a reusable adapter, make sure it is completely dry after the previous wash. Residues of old soap can react with the new composition, causing dissection or formation of a sediment that will clog the nozzle.
☑️ Ready to replace soap
Step-by-step: how to replace the cartridge
The replacement process itself takes no more than a minute if you act confidently and carefully. First, remove the dispenser from the wall mount or simply put it on a stable horizontal surface. Make sure the device is turned off if there is a mechanical switch on the body, although in most Xiaomi models the electronics themselves go to sleep.
Next, you should carefully unscrew the bottom with the empty bottle. Hold the top (motor head) strictly vertically so that the residue of soap does not leak into the case where the electronic board is located. Turn the device over and inspect the thread for contamination. If you use the original cartridge, just dispose of the empty and wind up the new one to the characteristic click or stop.
In the case of using a reusable adapter or refilling a native bottle, the algorithm is as follows:
- Unscrew the lid of the replaceable bottle and thoroughly rinse it with warm water.
- Pour the soap base, filling the volume by about 80-90%.
- Add water in the proportion specified by the soap manufacturer (usually 1:3 or 1:4 for concentrates).
- Shake the vial until a homogeneous mixture is formed without lumps.
- Swipe the bottle on the dispenser engine and turn on the device.
After assembly, you need to run a test run. Press the foam feed button or hold your hand to the sensor. The first 2-3 taps can give off air or watery mixture, which is normal, because the system takes time to fill the channels and create the necessary pressure. If after 5-7 attempts the foam is not going, check the tightness of the connection.
💡
For better foaming, use slightly warm water when diluting the concentrate - the foam is thicker and more stable.
Problems with the supply of foam and their solution
Quite often, after replacing the soap, users are faced with a situation where the dispenser is buzzing, but there is no foam, or it comes out too liquid. The most common reason is suffocation of the system. The pump tube forms an air plug that prevents the capture of fluid. To eliminate this, it sometimes takes several cycles to turn the device on and off.
Another common problem is the wrong consistency of the solution: if the soap is too liquid, it will simply flow out in drops rather than turn into lush foam. If it is too thick, the motor will run with overload. The optimal density is achieved experimentally, but the gold standard is the use of specialized concentrates for automatic dispensers.
⚠️ Warning: Never use soap with solid abrasive particles (scrabs) or glitter.They will inevitably get stuck in the valve and knock the pump out, turning a smart dispenser into a useless piece of plastic.
It is also worth checking the condition of the aerator mesh, through which air is mixed with soap solution. If it is filled with dried residues of soap, foaming will be impossible. Carefully rinse the meter nose with warm water using a soft brush, but do not pick the holes with sharp objects so as not to damage the membrane.
Comparison of original cartridges and analogues
Choosing between Xiaomi's original products and third-party solutions often depends on availability and budget.The original guarantees perfect compatibility, pleasant aroma and stable foaming, but its price and difficulty of buying in some regions can be repulsive. Analogues and reusable adapters offer savings but take time to find the right soap.
Below is a comparative table that helps to determine the choice:
| Characteristics | The original cartridge | Reusable adapter | Cheap analogue |
|---|---|---|---|
| Price. | Tall. | Low (price of soap) | Medium |
| Availability | Low (often unavailable) | Tall. | Medium |
| Foam quality | Stable, thick. | Depends on the soap. | Often watery |
| Environmental friendliness | Low (disposable plastic) | Tall. | Medium |
Reusable adapters are becoming an increasingly popular trend in the smart home community, not only saving money, but also allowing you to use your family's favorite antibacterial soap, and finding a quality adapter with good threads that won't leak when you're tightly attached to the engine is key.
The Secret to Perfect Foam
Device care and prevention of breakdowns
To keep the dispenser lasting, it needs to be properly cared for, and it is recommended that you flush the system completely every 2-3 months, and to do this, you pour clean warm water into the adapter, and the device is used until a clear liquid goes, which helps to remove the accumulated plaque and prevent the soap from drying out in the channels.
Pay attention to the state of the batteries. Alkaline batteries last much longer and more stable than salt cells, especially in devices with a motor that consumes current in jerks. If you notice that the foam is sluggish, even though soap is available, replace the batteries with fresh ones first.
⚠️ Warning: Do not leave the dispenser without soap on for a long time. Dry pump stroke can lead to overheating of the engine and deformation of internal seals.
It is also important to wipe the outer body and infrared sensor with soft wet cloth. Dust and spray on the sensor can reduce sensitivity, which will cause the dispenser to react to the movement of the hand late or not at all. Regular hygiene of the device is the key to its proper operation.
💡
Regular washing of the system with water and the use of high-quality batteries prolong the life of the dispenser by 2-3 times.
