How to pour water into the robot vacuum cleaner Xiaomi: full instructions with nuances

Xiaomi’s wet cleaning robots have become indispensable tools in the home, but many users are faced with the problem of how to properly pour water to avoid spoiling the device? Refueling errors can lead to leaks, breakage of the pump or even short circuit. In this article, we will examine all the nuances from the choice of water to the features of different models, including Mi Robot Mop 2 Pro, Viomi V3 and DreameBot W10.

It's important to understand that the refueling process depends not only on the model, but also on the type of tank (removable or built-in), whether you have a water flow control system, or even the hardness of the water in your area, and we've put together proven guidelines to help you avoid common mistakes and extend the life of your robot.

1.What water can be poured into a Xiaomi robot vacuum cleaner

Xiaomi's instructions indicate that only distilled or purified water is suitable for wet cleaning, but in practice, people often use tap water, and that can be a problem. Let's look at why water selection is so important.

Tap water contains calcium and magnesium salts, which when heated (if your model supports hot cleaning) or evaporated form scale on the pump and tubes.

• 🔧 Clogging of sprayers and reducing water pressure
• 🔋 Reduced life of pump (pump)
• ⚠️ Risk of corrosion of metal parts (in heated models)

If distilled water is not available, boiled or filtered water (e.g., reverse osmosis) can be used, avoiding water high in chlorine or iron. Auto-Wash models (like DreameBot W10) can be added to cleaners, but only those recommended by the manufacturer.

2. Step-by-step instructions: how to pour water into the tank

The refueling process may vary depending on the model, but the overall scheme looks like this. Consider the Xiaomi Mi Robot Mop 2 Pro, one of the most popular models with wet cleaning function.

Remove the robot from the docking station (if any)

Turn off power to the device

Remove the water tank (usually located in the back)

Check the cleanliness of the filter and sprayers-->

Step 1: Open the tank cover. Most models lock it with a latch or thread. Viomi V3, for example, turns the lid counterclockwise.

Step 2. Pour water to the MAX mark. Do not exceed this level - excess fluid can lead to leaks when the robot moves. In models with electronic level control (for example, DreameBot L10s Ultra), overflow is impossible - the system automatically blocks the bay.

Step 3. Close the lid before you click. Make sure the sealing gum is clean and undamaged. Even a small mottle can break the seal.

Step 4: Install the tank back into the robot. In some models (e.g. Xiaomi Mi Mop P), you press the tank until the characteristic click confirming the fixation.

⚠️ Warning: If the robot detects a Water Tank Error error after refueling, check if the tank is properly installed. Often the problem is solved by re-installing or cleaning the contacts.

3. Features of refueling in different models Xiaomi

Not all Xiaomi robot vacuum cleaners are the same, and let’s look at the key differences in the fueling process for the popular series.

Models with automatic wash docking stations (like the DreameBot L10s Ultra) require a special approach, where water is not poured into the robot itself, but into the station's tank.

• 💧 Monitor the water level in the station (usually there is a float sensor)
• 🧼 Use only original cleaning products
• 🔄 Regularly clean the station drain filter

💡

If your robot supports Auto-Wash, pour water into the station 10-15 minutes before cleaning starts, which will allow the system to warm up (if there is heating) and evenly distribute the detergent.

4.Typical gas station errors and how to avoid them

Even experienced users sometimes make mistakes that shorten the life of a robot vacuum cleaner, and here are the most common ones:

1. Water overflow: If you pour a liquid above the MAX mark, when the robot moves, it can spill out through the sprayers or get into electronic components. In models without a level sensor (for example, Mi Mop P), this is especially dangerous.

2. Use of inappropriate detergents: Mr. Proper or Fairy may cause:

• 🧪 A heavy foaming that will clog the tubes
• 🔋 Corrosion of seals and hoses
• 🚫 Loss of warranty (manufacturer prohibits use of uncertified funds)

3. Refueling with the robot on. In some models (for example, the Viomi V3), the pump can work when the tank is installed if the device is in cleaning mode, which will lead to water splashing.

⚠️ Warning: If the robot starts making unusual sounds after refueling (such as gurgling or grinding), turn it off immediately and check the tank's tightness.

5 How often should the water in the tank be changed?

Many users forget that the water in the tank should not stagnate. Even if the robot is not used every day, the liquid should be updated:

• 🕒 After each cleaning – drain the remaining water and dry the tank to avoid bacterial reproduction.
• 🌡️ Every one. 2-3 If the robot is idle, water can “bloom”, especially in a warm room.
• 🧴 After using the detergent – wash the tank with clean water to remove any remaining chemicals.

In self-cleaning models (e.g. DreameBot W10), water in the dock can be stored for up to 5-7 days, but only if the station is equipped with antibacterial coating, but even then weekly replacement is recommended.

To extend the life of the robot, follow a simple rule: if the water in the tank becomes cloudy or smells, it must be replaced and washed immediately, which will prevent mold from forming in the hoses and pump.

6.Can I put other liquids in the Xiaomi robot vacuum cleaner?

Beyond water, users sometimes experiment with other liquids -- disinfectant vinegar, purification alcohol, even flavorings -- but most of these experiments end badly, and we'll figure out what you can pour and what you can't pour.

✅ Permitted:

• 💧 Special cleaning products for robot vacuum cleaners (for example, Xiaomi Mi Home Detergent) are foam-free and safe for electronics.
• 🧼 Solution for washing glasses (diluted, 1:10) - only for models with detergent support.

❌ Forbidden:

• 🍋 Vinegar or citric acid – corrodes seals and can damage the pump.
• 🧴 Concentrated detergents (such as Domestos) – cause corrosion and foaming.
• 🌿 Essential oils – leave a greasy film on sensors and can cause allergies.

💡

Using uncertified liquids can result in a loss of warranty. Xiaomi's manufacturer only allows distilled water and original detergents.

7.Taking care of the tank: how to extend its service life

The water tank is one of the most vulnerable parts of the robot vacuum cleaner, and if left untreated, it can crack, become covered in plaque, or become a source of unpleasant odor.

1. Regular cleaning. After each cleaning:

• 🧽 Wash the tank with warm water (without detergents!).
• 🧻 Rub it with a soft cloth and leave to dry in an upside down form.
• 🔍 Check the sprayers for blockages (clean them with a toothpick).

2. Deep cleaning 1 time per month.

1. Soak the tank in a solution of water and baking soda (1 tbsp. spoon per 1 liter of water) for 30 minutes.
2. Clean the sealing gum with an old toothbrush.
3. Rinse all the details under running water.

3 Storage: If the robot is not used for a long time (e.g. during a holiday):

• 🚫 Completely drain water from the tank and hoses.
• 🌬️ Leave the cover open for ventilation.
• 📦 Keep the robot in a dry place at room temperature.

Pay special attention to sealing gum - it loses elasticity over time. If you notice cracks or deformation, replace it (parts can be ordered on AliExpress or in the official Xiaomi service).
