How to pour water into a vacuum cleaner Xiaomi: full instructions

Modern cleaning vacuum cleaners brand Xiaomi has become a popular solution to maintain cleanliness in the house, but many owners face difficulties already at the stage of preparing the device for work. The question of how to properly pour water into the tank is one of the most frequent, because the design of the tanks in different models is significantly different.

In this article, we will take a closer look at how water tanks are filled for a variety of models, including the Dreame H11, H12, H13 and Xiaomi Mijia Wireless Vacuum Cleaner. You will learn which water is best used, whether special products should be added, and what nuances exist to prevent scaling and bacteria from forming inside the system. Understanding these principles will prolong the life of your device.

Features of the design of Xiaomi tanks

The first thing you need to do before you start operating is to determine the type of device you have, because the water refill system is implemented in different ways. Most current models, like the Dreame H12 Pro or Xiaomi G10S, use a system of separate tanks: one for clean water and one for dirty water, which is critical, because mixing containers or trying to pour water into the mud collection compartment will cause the equipment to instantly fail.

Usually, a clean water tank is labeled as a droplet or is made of clear plastic with clear levels division. Dirty water is collected in a separate container, often equipped with a mesh filter and float that blocks suction when overflowing. The design of the clean water tank is designed to create a vacuum that prevents the liquid from leaking out spontaneously before the pump is activated.

It is important to note that in some models, such as the Dreame H11, the clean water tank is removable and integrated into the common unit, whereas in older or specific models it can be built-in. Before any manipulation, make sure that the device is turned off and disconnected from the charging station to avoid short circuit contacts.

• 💧 The clean water tank is always positioned above or in front of the engine to ensure flow or correct pressure.
• ⚙️ The tightness of the tank cover ensures the operation of the vacuum system of fluid supply to the brush.
• 🚫 Never try to force the tank if it does not enter the grooves - check the correct orientation.

Preparation of water and detergent solution

The quality of the liquid used directly affects the durability of the pump and spray nozzles. Xiaomi engineers recommend using tap water at room temperature, but in regions with very hard water it is better to filter it beforehand or use bottled water, which will help to avoid rapid scale formation inside thin tubes and heating elements (if the model provides a function of hot water).

The use of household chemicals requires special attention, and manufacturers often point out that only the brand’s original cleaning products can be used, because conventional floor shampoos can create excessive foam that will get into the engine and disable it, or contain aggressive components that corrode plastic seals.

Water temperature also matters. If you pour hot water into a model that doesn't support heating, make sure it doesn't exceed 40°C. Too hot liquid can warp the plastic parts of the tank and disrupt the electronic sensors that monitor the fluid.

Step-by-step: how to pour water

The process of filling with water is simple, but requires a certain sequence of actions to ensure that the system is tight. First, you need to remove the clean water tank from the vacuum cleaner housing. Depending on the model, it can be removed by moving upwards or snapping the retainer from the side. Be careful not to damage the plastic latches.

Open the valve or filler cover. In Dreame models, it is often a swivel rubber seal cover that needs to be turned counterclockwise. Xiaomi Mijia models can use a push-to-open system. Pour water strictly to the MAX mark, avoiding overflow, as when the cover is closed, the fluid level will rise and can enter the air channel.

Once filled, close the lid tightly. Make sure the rubber seal is not pinched and lies exactly around the perimeter. If the lid is not sealed, no vacuum will be created and no water will be supplied to the brush during cleaning. Then install the tank back into the vacuum cleaner body until the characteristic click.

⚠️ Warning: Never tilt the vacuum cleaner horizontally or upside down immediately after refilling the water.The liquid can enter the engine compartment through the vents, which will lead to irreversible failure of the electronics.

Comparison of models: where is the tank

Different generations of devices have different design features, and to make it easier for you to navigate, we have prepared a table describing the location and volume of tanks in popular models, which will help you quickly find the right compartment and not confuse it with a container for dust or dirty water.

As you can see from the table, tank volumes vary, which affects the battery life in wet cleaning mode. In models with an integrated tank (as in the H12 Pro), the refueling process can occur directly at the docking station if the auto-fill function is provided, but most often the tank still needs to be removed to control the purity level.

For dual tank models, it is important to visually distinguish them by color or marking: Pure water is usually in a tank with blue or transparent elements, whereas a dirty water tank often has orange or red accents and a more complex internal structure with filters.

Typical errors in operation

One of the most common mistakes is to ignore the regular flushing of the clean water tank. Even if you only use water, bacteria can multiply inside over time and produce an unpleasant odor that will spread throughout the apartment during cleaning. It is recommended to rinse the tank with warm water after each 2-3 utilization.

Another common problem is that hot water is used in models without heating function, and many users mistakenly believe that hot water is better at washing fat, and they pour it into a regular vacuum cleaner, which causes the plastic to soften, deform the seals, and the pump membrane to fail, which is designed for a certain temperature regime.

💡

To keep the water in the tank fresh longer, add a drop of tea tree essential oil (if the model allows the use of additives) or simply change the water more often, without leaving it in the tank for storage for more than 24 hours.

Users also often forget to check the HEPA filter and other elements located near the tanks. If clean water accidentally enters the water tank (due to an assembly error), this can lead to clogged suction system.

Care and maintenance of the water supply system

To ensure that the water supply system works smoothly, you need to periodically carry out preventive cleaning. Once a month, it is recommended to wash the tank with a solution of citric acid or a special scale remedy, especially if you have hard water, this will remove mineral deposits from the inner walls and pump.

Be sure to dry the tank before long storage. Leave the lid open and place the tank in a well-ventilated place. The humid environment inside the closed container is the ideal place for mold to develop, spores of which can be spread around the house the next time you turn on.

⚠️ Warning: If you notice that the water has stopped flowing to the brush, do not try to disassemble the pump yourself.First check if the supply hole is clogged with water or pile, and make sure that the tank lid is sealed.

Regular water replacement and proper storage of the device ensures that your Xiaomi or Dreame will last for years to come.Remember that using distilled water in models with a steam generator or heating is a must-have to maintain warranty.

💡

The main secret of long-term service of a cleaning vacuum cleaner is not to leave water in the tanks after cleaning and use only the cleaning products recommended by the manufacturer.
