Owners of Xiaomi robotic assistants often wonder how to fill a wet cleaning tank to keep the machines clean. Ultrasonic floor washing is an effective method, but it requires strict adherence to fluid rules. The wrong choice of chemistry can cause pumps to fail, nozzles to clog or persistent foam that will put electronics out of order.
Modern models, such as the Xiaomi Robot Vacuum X10+ or Xiaomi Vacuum-Mop 2 Pro, are equipped with a complex water supply system that is sensitive to the viscosity and chemical composition of the solution. It is critical to understand that the use of aggressive alkalis or acids is unacceptable in any model of robot vacuum cleaners. In this material, we will analyze which fluids are approved by the manufacturer and which are strictly prohibited for use in the Aqua system.
Official requirements of the manufacturer for liquids
Xiaomi engineers designed a wet cleaning system based on the use of ordinary tap water, because the fluid supply mechanism is often based on gravity or low pressure created by a miniature pump. Any deviation from the neutral environment can disrupt the calibration of water level sensors or lead to plaque on the inner walls of the tank.
If you plan to use specialized products, you need to make sure that they completely dissolve in water and do not form precipitation. Foaming is the main enemy of robotic systems, since foam can get into the pump engine or on the main control board. In the instructions for most models of the Vacuum Mop series, it is expressly stated that you need to use only water or special products marked "for robotic vacuum cleaners".
Using aggressive chemicals can cause rubber seals and plastic tubes to break down inside the device’s body, causing leaks that are extremely dangerous to the electronics at the bottom of the robot, so Xiaomi strongly advises against experimenting with household chemicals that are not designed for smart appliances.
Specialized tools for robotic vacuum cleaners
There are special concentrates in the cleaning market that are designed specifically for robots, which differ from regular Flor Cleaner in that they contain components that prevent foam formation even when actively stirring, often labeled "Low Foam" or "No Foam", which is a key safety factor for Xiaomi's pump.
One popular solution is the original Xiaomi Mijia Floor Cleaner, which is designed with the materials used to make the company’s tanks and tubes, and is free of abrasive particles and aggressive solvents that could damage the internal water supply system.
- 🧼 Complete absence of foam when working the high pressure pump.
- 💧 Fast solubility without flake or precipitation.
- 🛡️ Safety for rubber seals and plastic parts.
- 🌿 Environmentally friendly composition, safe for children and pets after drying.
When using specialized products, it is important to observe the dosage. Usually, one liter of water requires only a few caps of concentrate. Excessing the concentration will not make cleaning more efficient, but it can leave a sticky layer on the floor that will attract dust immediately after drying.
💡
Always add a cleaning agent to the water, not the other way around, which will help the solution mix better and avoid local concentration of chemistry at the bottom of the tank.
Can I use ordinary household products?
Many users try to save money by pouring in the tank familiar floor washing fluids, such as Mr. Proper or Glorix, this is strongly discouraged. These tools are designed for buckets of water and active manual mop work, where the formation of foam is controlled mechanically, in a closed system of the robot foam will rise to a critical level in minutes.
⚠️ Warning: The entry of a foamy substance into the dust collection compartment or on the engine contacts may cause short circuit and irreversible failure of the device, which will not be recognized as a warranty case.
Also, conventional remedies often contain fragrances and dyes that can clog the thin nozzles of the sprayer. Xiaomi Vacuum Mop has very narrow water supply channels, and any plaque or salt crystallization can completely block the flow of the liquid.
Another negative factor is the smell. In a regular bucket, the fragrance is spread over a large area, and in a robot tank, the concentration of chemical vapors is high. When operating, the device can spread an too sharp smell that will not be pleasant to households and pets. So using universal cleaning products is a risk that does not justify the potential savings.
Prohibited substances and their effect on technology
There is a list of substances that are strictly prohibited in Xiaomi robotic vacuum cleaners, including chlorine-bearing bleach, acidic scale-removal agents, and alcohol- or acetone-based solvents, which are chemically aggressive and can literally melt plastic parts of the tank or destroy the adhesives of the tubes.
A particularly dangerous abrasive particles, which can be found in some cleaning powders or emulsions, act like sandpaper as they pass through the pump, quickly wear out the work surfaces and disable the pump, and even microscopic scratches inside the water supply system will lead to lower pressure and poor cleaning in the future.
| Type of substance | The impact of the Xiaomi robot | Risk of breakdown |
|---|---|---|
| chlorine bleach | Destruction of plastic and rubber | High-pitched |
| Soap solution | The formation of abundant foam | critical |
| Oil emulsions | Clogging of nozzles and tubes | Medium. |
| Acid products | Corrosion of metal parts of pump | High-pitched |
And oils are also worth mentioning, and they leave a greasy film on the floor, but also on the wheels of the robot, which reduces grip on the surface, and the device can start to tow, lose the map of the room, or get stuck on carpets, and oily substances are difficult to wash out of the internal tank, and the smell can persist for a very long time.
What to do if you have a prohibited product?
Use of distilled and boiled water
Water quality is as important as detergents. Tap water often contains hard salts that, when dried, form white plaque (scale), and over time, this plaque accumulates in the tank and can enter the spray system. For regions with very hard water, distilled or demineralized water is a great prevention.
Boiled water is also suitable for use, as the boiling process reduces hardness and kills bacteria that can multiply in the stagnant water of the tank. However, it is important to let the water cool completely before pouring. Hot water can warp the plastic tank or damage level sensors designed for a certain temperature regime.
Regular use of clean water without chemical additives prolongs the life of the device. If you use ordinary tap water, it is recommended to completely empty the tank once a week and wipe it with a dry cloth, this will prevent the appearance of an unpleasant smell of mustyness and the reproduction of microorganisms inside the tank.
Proper care of the tank and the supply system
For Xiaomi Vacuum Mop to last a long time, you need to follow the rules of hygiene of the tank itself. After each wet cleaning, it is recommended to drain the remaining water. The liquid in the tank is the ideal environment for the development of bacteria and mold, especially if the device is stored in a warm place.
Once a month, do a preventive cleaning of the tank, which you can use a weak solution of citric acid if you notice signs of scale, but after that the tank needs to be very carefully rinsed. Make sure that the magnetic valve (if you have one in your model) is free to walk and does not stick to dirt.
☑️ Monthly tank care
Remember to check the condition of the rag or electronic mop. If the fabric is too contaminated or soaked in chemicals from previous cleanings, the efficiency of the washing decreases and the load on the engine increases. Timely replacement of consumables ensures that the water supply system will work normally without overloading.
💡
The safest and most effective way to clean is to use distilled water and dry the tank regularly after each application.
