Keeping the house clean with modern gadgets has become an integral part of everyday life, and Xiaomi Vacuum Mop Essential is one of the leading places here due to its availability and functionality. However, like any technical device, it requires proper maintenance to work efficiently. Many users face difficulties already in the preparation for wet cleaning, not knowing how to properly fill the system with water without risking damage to electronics.
Mishandling the liquid tank can cause major robot nodes to fail or simply cause poor floor cleaning. In this article, we will look at the entire process, from extracting the tank to adjusting the water intensity through the application, you will learn which fluid is best to use and how to avoid the typical mistakes that beginners make when using this model.
To start with, it's important to understand that the water supply system in this model is gravitational, not pumping, which puts certain limitations on use, which is why it's critical to follow the sequence of actions when refueling, and the water must be poured strictly into a special compartment of the tank, bypassing electronic contacts and the dry dust compartment.
Water tank design and preparation for refueling
Before you start filling the tank, you need to visually inspect the design of the module. In the Essential model, the tank is combined with a garbage container, but has a clear separation of zones. There's a lid on top that covers the liquid compartment, and on the side or bottom (depending on the modification) there are pump holes to draw water. HEPA-filter.
To get started, remove the top cover of the robot vacuum cleaner to access the insides. Carefully remove the combined module by taking up special grooves on the sides. Note that you need to hold it strictly horizontally so that the remains of dry dust from the adjacent compartment do not fall into the water. Inside you will see two main compartments: one for garbage collection and the second, usually smaller, with a rubber cap.
- 💧 Rubber plug - protects electronics from moisture.
- 🛡️ Mesh filter – prevents large debris from entering the system.
- 🔌 Pump contacts – require special care when servicing.
It is strictly forbidden to pour water if the module is installed inside the robot, this can lead to a short circuit, also make sure that the rubber plug sits tightly in place before the procedure begins, any deformation of the seal can cause a leak in the future.
Step-by-step: how to properly pour water
The process of filling the tank requires care, but it is not complicated to execute. First open the rubber cap on the tank. The water should be at room temperature, because the use of hot liquid can deform the plastic elements of the structure. Pour the liquid slowly, keeping track of the level, to prevent overflow over the edge.
Use only purified or distilled water. Tap water contains calcium and magnesium salts that eventually form scale. This scale clogs micro holes in the rag holder and can disable the pump. If you only have tap water on hand, be sure to pass it through a household filter jug.
☑️ Checklist before launch
Once filled, close the plug until you click or fit tightly. Rub the outside of the tank with dry rags to remove droplets that may have accidentally come out. Only then can the module be returned to its place. Put it in the robot with guides and close the top cover of the device.
⚠️ Warning: Never add liquid detergents, chlorine or flavorings to the tank. Aggressive chemicals destroy rubber seals and plastic, and foam can disrupt the vacuum water supply system.
Installation of the rag holder and adjustment of the water level
Once the tank is filled and installed, you need to prepare a water distribution system, and on the bottom of the robot, a special platform is attached with a microfibre wipe attached, water from the tank flows spontaneously or under low pressure on this napkin, and it is important to set the supply level correctly so that the floor is not too wet or, conversely, dry.
You can set it up through the Mi Home or Xiaomi Home app. In the device management interface, find the cleaning settings section. There's a slider or a choice of three modes: low, medium and high. For daily maintenance cleaning, you usually need a mid-level, whereas for old spots, you better choose the maximum.
| Feeding regime | Water consumption | Which genders are suitable for | Time to work. |
|---|---|---|---|
| Low. | ~6 ml/min | Laminate, parquet, sensitive coatings | 120 minutes. |
| Medium. | ~9 ml/min | Tiles, linoleum, mixed coatings | 90 minutes. |
| High-pitched | ~12 ml/min | Severe pollution, porcelain | 60 minutes. |
When choosing a mode, consider the type of flooring. Wooden floors do not tolerate excess moisture, so high-feed mode is strongly discouraged. If you use the robot for the first time, start with minimal settings and gradually increase the intensity, watching the result.
What if the water does not go to the rag?
Typical errors in the operation of the moisture system
One of the most common mistakes is leaving the water in the tank after cleaning is done. If the robot vacuum cleaner is not scheduled for use in the coming days, the water must be drained. The stagnant fluid is the perfect medium for bacteria to multiply, which leads to unpleasant odors on the next switching.
Another mistake is to use hard tap water without filtration, where hardness salts are deposited on the walls of the tank and in the supply channels, gradually reducing their throughput, which can eventually lead to a complete blockage of the water supply, and then you need to disassemble and clean the system using citric acid.
- 🚫 Leaving wet rags in the sun - leads to hardening of the tissue.
- 🚫 Ignoring app signals about low water levels.
- 🚫 Installation of the tank with water during dry cleaning (unnecessary load).
Also, users often forget to check the condition of the microfiber wipe itself. If it is contaminated or plaque formed on it, the cleaning efficiency decreases significantly. The wipe must be washed regularly, but this should be done without using air conditioners for laundry, as they reduce the absorbency of the fabric.
⚠️ Warning: Before installing a water tank, make sure that the robot does not have a dry dust container from another model or a water tank. HEPA-filter in the wrong position, which can cause mechanical damage to the internal components.
Maintenance and care of the water module
Regular maintenance extends the life of the device. After each wet cleaning, it is recommended to remove the module, drain the remaining water and wipe it with a soft cloth. Once a week, conduct a more thorough cleaning: rinse the tank with warm water and let it dry completely before the next installation.
Pay special attention to pump contacts. If they show oxidized plaque, gently wipe them with a dry cotton swab. Do not use metal objects for cleaning, so as not to damage the gold spray of the contacts. The purity of these elements ensures the stable operation of the water supply system.
💡
Tip: If you are going on vacation for a long time, keep the water module separate from the robot with the lid open so that mold does not form inside.
Check the integrity of the rubber seals. Over time, they can tan or crack. Replacing the seal is a simple procedure that will prevent water from leaking into the robot body. If defects are detected, it is better to order a new part immediately than risk the device's electronic board.
Solving water supply problems
If you notice that the robot has stopped wetting the cloth, even though there is water in the tank, take it slowly to the service. Often the problem is in the air traffic jam. Try turning the module upside down several times (pre-closing the plug) and shake it slightly, which will help the air to get out and the water to fill the channels.
Also check the settings in the app. Sometimes, after updating the firmware or resetting the settings, the water supply level can automatically switch to minimum or zero. Make sure that the app activates wet cleaning mode and selects the appropriate flow intensity.

💡
Proper water preparation and regular cleaning of the tank are the key to a long service of the robot vacuum cleaner and high-quality wet cleaning without divorces.
Compliance with these simple rules will allow you to enjoy clean floors without unnecessary hassle and expensive repairs. Xiaomi Vacuum Mop Essential is a reliable assistant, if you treat it with an understanding of the technical nuances.
