Where to pour water into the robot vacuum cleaner Xiaomi: the location of the tank and the rules of operation

Xiaomi’s wet cleaning robots require proper water handling, which not only determines the quality of the floor washing, but also the life of the device. Many users are faced with the problem of where the water tank is located, how to fill it properly and what errors can lead to breakage. In this article, we will analyze all models of Xiaomi’s robot vacuum cleaners (including Mi Robot Vacuum-Mop, Viomi and Dreame), show the exact layout of the tank, explain how much water to pour and how to avoid common mistakes.

Xiaomi robots have a unified design, but with nuances depending on the series. For example, in models with automatic change of modes (dry / wet cleaning), the water tank is often integrated into the main body, whereas in budget versions it can be removable. We will look at each modification in detail, so you know exactly where and how much to pour water, so as not to damage the electronics.

Important: If you are using a robot vacuum cleaner with floor washing function for the first time, be sure to read the section on water types and detergents - the wrong choice of liquid can lead to corrosion of contacts or clogging of the water supply system.

1.Where is the water tank in Xiaomi's robot vacuum cleaners

In most Xiaomi models, the water tank is located on the back of the case, under the lid with the pictogram of the drop.

• 🔹 Mi Robot Vacuum-Mop (1/2/Pro/P): The tank is on the right (if you look at the robot in the front) and it's mounted on the latches — 200–300 millimeter.
• 🔹 Viomi V2/V3/SE: water tank combined with a dust container (system) 2-in-1). The lid opens by pressing the button from above.
• 🔹 Dreame D9/F9/Z10 Pro: the tank is taken out separately and is located on the left. In models with self-dosing water (for example, DreameBot). L10s Ultra) has two compartments - for clean and dirty water.
• 🔹 Budget models (for example, Mi Robot Vacuum-Mop Essential): removable tank, attached to the side on magnets.

To find the tank, focus on:

1. A wave-pictogram (🌊) drop-on.
2. The inscription WATER TANK (on export versions).
3. A button or latch – usually highlighted in color (blue, green).

If you can’t find the tank, check the instructions for your model – in some cases (such as in Xiaomi Mi Robot Vacuum-Mop Pro), the tank is hidden under the top cover and requires pressing two latches at the same time.

2. Step-by-step instructions: how to properly pour water

The process of filling the tank seems simple, but there are key points that affect the work of the robot:

Disconnect the robot from the charging station

Make sure the tank is empty and dry.

Use only distilled or boiled water

Do not exceed the maximum level (MAX mark)

Close the tank lid before you click.-->

Now let's take the process one step at a time:

1. Remove the tank: press a button or pull a special ledge. Viomi models may need to first remove the dust container.
2. Rinse the tank (if it’s not the first pour): Use warm water, but no detergents – they can leave the film.
3. Fill the tank: 💧 For Mi Robot Vacuum-Mop 2: maximum 200 ml. 💧 For DreameBot. L10s Ultra: 400 ml in clean water compartment. 💧 For Viomi. V3: 250 ml (there is a transfusion sensor).

Put the tank back in.

⚠️ Warning: If the robot makes an error after pouring water E5 or E6, It means the tank is installed incorrectly or there is a leak.

3. What water can be used: requirements and prohibitions

Water quality is the key to the life of the robot vacuum cleaner pump and tubes, and Xiaomi recommends:

* Cleaners can only be used if they are Xiaomi certified (e.g. Xiaomi Mi Floor Detergent). Common floor washing fluids contain surfactants that form foam and disable humidity sensors.

🔹 Tip: If you use tap water, install a filter or stand it for at least 12 hours, which will reduce the salt content and prolong the life of the pump.

💡

After each cleaning, drain the remaining water from the tank and dry it in air - this will prevent mold and unpleasant smell.

4. Frequent mistakes and how to avoid them

Even experienced users sometimes make mistakes when working with a water tank. TOP-5 problems and solutions:

• 🚫 Water overflow: If you pour more than the maximum, the robot can stop with an error E3 (Solution: drain the surplus and restart cleaning.
• 🚫 Hot water use: deforms the plastic in the tank, optimum temperature 15-25°C.
• 🚫 Closing the lid without clicking: If the tank is not fixed, the robot will not start cleaning or will issue an error E1.
• 🚫 Storing a robot with water in a tank: after 2-3 days, the smell appears. Always drain the water after cleaning!
• 🚫 Using vinegar/citric acid to clean the tank: aggressive substances corrode seals.

⚠️ Warning: If the robot starts to sneeze after pouring water (stop abruptly and make sounds), this is a sign of fluid entering the dust collector.

5 Features of water pouring in different models Xiaomi

The tank design and the water supply system differ from series to series, and let's look at the key models.

Mi Robot Vacuum-Mop 2 / 2 Pro

Removable tank, volume of 200 ml. Features:

• 🔹 There is a regulator of the intensity of water supply (3 levels).
• 🔹 When pouring water over 180 ml, the robot automatically reduces the pressure.
• 🔹 The tank cover is transparent - the liquid level is visible.

Viomi V3

2-in-1 system: water and dust tank combined.

• 🔹 Maximum water volume is 250 ml, but it is optimal to pour 200 ml.
• 🔹 There is a sensor of water pollution - with severe pollution, the robot stops.
• 🔹 The tank is washed only by hand (not in the dishwasher!).

DreameBot L10s Ultra

Two containers: clean (400 ml) and dirty water (350 ml) Nuances:

• 🔹 Automatic self-cleaning of the rag after cleaning.
• 🔹 In the tank for clean water can be added detergent (but not more than 5 ml).
• 🔹 There are UV lamps for disinfecting water.

💡

In models with two tanks (clean/dirty water), never pour water into the compartment for dirty water - this will lead to a breakdown of the filtration system.

6.How to care for a water tank: cleaning and maintenance

Regular cleaning of the tank prolongs the life of the robot vacuum cleaner.

1. After every cleaning: 🧽 Pour the remains of water. 🧽 Rinse the tank with warm water. 🧽 Wipe the sealing gum with a dry cloth.
2. Once a week: 🧼 Use a soft brush to clean the internal walls. 🧼 Check the nozzles for blockages (you can clean with a toothpick).

Once a month

• 🔄 Soak the tank in a solution of soda (1 tbsp. l. per 1 liter of water) for 30 minutes.
• 🔄 Rinse the water supply system (if you have access to the tubes).

⚠️ Attention: if there is a black coating (mold) in the tank, use specialized means to clean the tanks of robot vacuum cleaners (for example, Kärcher Cleaner for Robotic Vacuums: Bleach or aggressive chemicals will damage plastic!
