Xiaomi’s wet cleaning robots have become indispensable home cleaning tools, but new users often wonder where to put water to avoid damaging the device. Water refilling errors can lead to leaks, pump failures, or even electronic components failure. In this article, we’ll look at all models of the Vacuum Mop line (including the S10, S12 Pro, T10+, and others), show the location of the tank, explain the nuances of the pour, and warn against typical errors.
Xiaomi's water tank design is different from traditional mops and even from other brands. There's no usual hole on top, it's designed to minimize the risk of liquid spilling onto electronics. If you first encounter this technique, the intuitive "open the lid and pour" solution can get you into trouble. Next, you'll learn how to handle the water tank properly, what liquids are acceptable, and what to do if the robot stops spraying water.
Design of the robot vacuum cleaner Xiaomi Vacuum Mop: where to look for a water tank
In Xiaomi Vacuum Mop models, the water tank is integrated into a removable container that simultaneously serves as a dust collector, which saves space and simplifies the design, but requires careful handling.
- 🔹 Right (when you look at the robot from the front) - in models S10, S12 Pro, T10+.
- 🔹 Back under the cover - in older versions, for example, Vacuum Mop P.
- 🔹 In the central module - in compact models such as Vacuum Mop 2 Lite.
To find the tank, look for a blue or transparent container with a lid – it is often signed with a water icon (wavy lines) or the inscription WATER TANK. In some models, the tank is hidden under the top panel and is only removed after pressing the lock.
Important: don't confuse a water tank with a dust container, which is usually black or gray, and is on the left, and trying to put water in a dust collector is one of the most common causes of breakdowns!
Step-by-step: how to properly pour water
The process of refilling water seems simple, but there are critical nuances. Follow this algorithm to avoid leaks and damage:
- Turn off the robot and remove it from the dock (if any) to prevent accidental switching on during refueling.
- Remove the water tank: 🔧 On models S10/S12 Pro press the lock button on the side and pull the container up. 🔧 V T10+ Lift the lid, then pull the tank out with a motion "on yourself".
Open the tank lid.
- 🔄 Foldable (turned on hinges).
- 🔄 Removable (completely removed).
- 🔄 With a lock (you need to press the button).
- Pour water to the MAX mark, and overflowing will cause overflow during cleaning.
- Close the lid before clicking - this guarantees tightness.
- Install the tank back, making sure it sat tightly in place (the click of the fixator should be heard).
💡
To remove scale in the pump, once every 3 months, pour a solution of citric acid (1 tsp. per 1 liter of water) into the tank, then rinse with clean water. This will prolong the life of the robot.
Frequent mistakes in pouring water and how to avoid them
Even experienced users sometimes make mistakes that lead to breakdowns, and here are the most common ones and ways to prevent them:
- 💧 Water overflow above the mark MAX → When the robot moves, the fluid is released through the vents, hitting the board. Solution: Use a measuring glass or syringe for accurate dosing.
- 🔌 Water pouring with connected power → Short circuit risk if liquid gets to the contacts. Solution: Always remove the robot from the dock before refueling.
- 🧼 Use of aggressive detergents → The foam clogs the pump, and the chemical additives corrode the gaskets. Solution: Specialized compounds for robot vacuum cleaners only.
- 🔄 A loosely closed tank lid → Water leaks out during cleaning, leaving wet footprints.Solution: Check the lid fixation before you click.
- ❄️ Refrigeration of cold water after hot cleaning → A sudden temperature drop can damage the plastic parts of the tank.Solution: Let the robot cool for 10-15 minutes.
One of the most insidious mistakes is ignoring the residue of water in the tank after cleaning, and if you leave the liquid for a long time, it becomes a breeding ground for bacteria, and in the cold season it can freeze, deforming the container. Always drain the water after cleaning!
What if the robot stopped spraying water?
Features of pouring water in popular models Xiaomi
The design of the tank may vary depending on the model. Let's consider the nuances for the most popular devices:
