What Xiaomi Dispensers Models Support Replaceable Blocks

Not all Xiaomi devices have removable cartridges, and here is a list of models that are suitable for this instruction:

• 🔹 Xiaomi Mijia Automatic Soap Dispenser (Basic Version, DJT01CM) — The most common version with a capacity of 300 ml.
• 🔹 Xiaomi Mijia Automatic Soap Dispenser Pro (DJT02CM) — Improved version with proximity sensor and a capacity of 400 ml.
• 🔹 Xiaomi Mijia Automatic Soap Dispenser Mini (DJT03CM) — compact model of 250 ml for travel.
• 🔹 Xiaomi Youpin Smart Soap Dispenser (YLYD01YL) — model with lighting and blocking function from children.

Outdated versions (e.g. Xiaomi Viomi or early unlabeled prototypes) DJT) They may not be compatible, and to test your model, look at the bottom of the device -- it's exactly marked -- if your model isn't on the list, don't try to fill it up yourself, because in some dispensers, the cartridge is soldered into the body.

Also, pay attention to the type of cartridge attachment:

• 🔄 Cartridge is screwed into the base (typical for Pro and Youpin models).
• 🔳 Latches - the block is fixed with plastic clips (basic and Mini-versions).

What can be refueled with a replacement unit: the original vs alternatives

The manufacturer recommends using only original Xiaomi cartridges with liquid soap (article) DJT-SOAP-01 However, their price (from 300 to 500 rubles per unit) makes the operation of the dispenser unreasonably expensive. Fortunately, there are proven alternatives:

Critical point: the viscosity of the liquid should be within the limits 1000–3000 mPa·s (millipascal-seconds) To check the density without special devices, flip the bottle of liquid - if the contents leak out at a speed of 1 A liquid that is too thick (like an undiluted gel) can burn the pump engine for a second. 2-3 weekly.

⚠️ Warning: Never fill the dispenser with liquids based on acetone, alcohol (more than 20%) or abrasive particles (scrabs) This will lead to cracking of the plastic cartridge and leaks. For example, the antiseptic "Sterillium" corrodes the sealing ring in 5-7 days.

💡

If you use a shower gel, dilute it with warm water in a 1:1 ratio and add 1 teaspoon of glycerol per 100 ml of the mixture - this will improve the slip and protect the pump from wear.

Step-by-step instructions: how to fill a replacement block

Before you start, prepare:

• 🧼 New cartridge (original or empty for refueling).
• 💧 Refilling fluid (see section above).
• 🧻 Wraps or paper towels (for cleaning the leaks).
• 🔧 Plastic blade or dull screwdriver (for models with latches).

Step 1: Removing the old cartridge

1. Turn off the dispenser from power (take out the batteries or disconnect). USB-cable).
2. Turn the device upside down. In threaded-mounted (Pro) models, turn the cartridge counterclockwise. For latches, press the locks on both sides (usually marked with arrows).
3. If the cartridge does not respond, put a plastic blade on the side - but do not apply force to the pump!

Step 2: Cleaning and preparation

• Wash the empty cartridge with warm water (without detergents!).
• Check the sealing ring on the basis of the dispenser - if it is deformed, replace it (can be cut from silicone pad for cans).
• Dry all the details with a napkin, the moisture inside the cartridge will lead to dilution of the soap and leaks!

Step 3: Filling the cartridge

Pour the liquid to the mark. MAX (higher!)|Make sure there are no air bubbles|Tightly twist the cartridge cover|Wipe threads/contacts from the leaks-->

Use the bottle's funnel or nose to pour the liquid slowly, without splashing. If you fill it with non-original soap, leave 5 mm of free space - when heated (for example, in the kitchen), the liquid expands and can leak.

Step 4: Install the cartridge back

• For threaded mounting: screw the cartridge clockwise to the point, but do not pull.
• For latches: insert the block before clicking, then click on it from above to fix.
• Make sure the sealing ring does not move.

Step 5: Testing

Turn on the dispenser and check the work:

1. Bring your hand to the sensor - should give a portion of soap 1-1.5 ml.
2. Check the bottom of the device for leaks (especially in the first 10 minutes).
3. If the soap is not coming, repeat steps 3-4 - there may be air left in the pump.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakdowns.-5 problems and solutions:

1. Leaks after refueling: damaged sealing ring or liquid overflow solution: replace the ring (you can buy a remix for 50-100 rubles) and fill the cartridge with 90% of the volume.
2. The dispenser gives out too little soap, because it's thick liquid or air in a pump, so you can dilute the soap with water (10 ml at a time) or pump the pump with 10 taps.
3. The device doesn't turn on after refueling, because liquid hits the contacts in the battery compartment, so you can dry the contacts with an alcohol napkin and check the polarity of the batteries.
4. Soap foaming inside the cartridge Reason: use of funds with SLS (Solution: wash the cartridge and fill it with soap without aggressive surfactants (e.g. Ecover).
5. The pump is noisy, but the soap is not going, because it's clogged with a silicone tube or wear on the engine, so you can either clean the tube with a needle (carefully!) or go to the service.

⚠️ Warning: If after refueling, the dispenser starts to emit grinding or vibration, turn it off immediately! This is a sign that the pump is running "dry" (for example, if the soap is too thick). Continued use will lead to burnout of the engine, and its replacement will cost 60-70% of the cost of the new dispenser.

How to prolong the life of the cartridge: life hacks and savings

The original Xiaomi cartridges are designed for 300-400 taps, but with proper care, they can be used 3-5 times longer.

• 🔄 Reusable refill: Wash the cartridge after each use (just rinse with warm water) and dry in air. This will last up to 10 cycles of refilling.
• 💧 Dilution of soap: Add 10-15% distilled water to the liquid – this will reduce the load on the pump and increase the volume by 20%.
• 🧴 Alternative containers: Buy empty cartridges on AliExpress (article) DJT-EMPTY) — They are cheaper than the original 3 times.
• 🔋 Battery savings: Turn off the dispenser overnight (if it's battery-powered) - this will extend their lives from 2 to 4 months.

There's another trick for the Xiaomi Mijia Pro: you can reduce your soap from 1.5 ml to 0.8 ml in the settings of the Mi Home app, and this reduces your consumption by 40 percent without losing convenience.

1. Open the Mi Home app and select your dispenser.
2. Go to Settings. → Dosage. → Small volume.
3. Save the changes and test the device.

💡

Using distilled water to dilute soap prevents the formation of lime plaque on the pump, which is the main cause of breakdowns after 6-12 months of use.

If you fill the dispenser with a homemade mixture, experiment with additives:

• 🍯 Honey (1 tsp per 200 ml) – softens the skin, but can crystallize at low temperatures.
• 🌿 Essential oils (2–3 drops) – give a flavour, but avoid citrus (they corrode plastic).
• 🧂 Sea salt (a pinch) - for a slight scrubbing effect, but requires careful dissolution.

Where to buy consumables: original vs analogues

Original cartridges and liquids for Xiaomi can be bought in several places, but the prices and delivery times are very different:

When buying on AliExpress, pay attention to the seller's rating (should be above 98%) and reviews with photos. Often, under the guise of original cartridges, they sell fakes with thin plastic that cracks after 2-3 gas stations.

• 🏷️ Hologram with Xiaomi logo at the bottom.
• 🔢 Serial number beginning with DJT-.
• 📦 Packing with QR-code (leads to the official website).

Analogs from third-party brands (such as Baseus or Yeelight) are usually 30-40% cheaper, but their quality varies. According to our test, the best non-original cartridges are produced by the Aqara brand – they are 100% compatible with Xiaomi and can withstand up to 15 refueling cycles.
