How to pour water into the robot vacuum cleaner Xiaomi Vacuum Mop P: instructions with photos and tips

Xiaomi Vacuum Mop P combines dry and wet cleaning, but many users have difficulty using the floorwashing function for the first time. Incorrect water filling can lead to leaks, breakage of the pump or inefficient cleaning. This article will explain what water to use, how to avoid common mistakes and what to do if the robot does not spray liquid.

The Vacuum Mop P is different from previous versions of Xiaomi, which uses an electronically controlled removable water tank, which means that simply pouring water into the tank is not enough: you need to consider the level of filling, the type of liquid and even the sequence of actions when installing the tank. We will describe each step in detail, including hidden nuances that are not written in the official instructions.

Preparing the robot for wet cleaning: what to do before refueling

Before you pour water, make sure the robot is ready to moping.Missing these steps can cause malfunctions or damage to machinery.

First, check the package: in the box with Xiaomi Vacuum Mop P should be a special water tank (usually white with a blue lid), a wipe for washing and a mount for it. If something is missing, do not use homemade analogues, it is dangerous for technology. Second, update the firmware of the robot through the Mi Home application, as in older versions of the software there are possible bugs with spray control.

• 🔋 Battery charging: charge level should be at least 50%.At low charge, the robot can interrupt cleaning, leaving the floor wet.
• 🧹 Cleaning the dust collector: remove the garbage from the main container – when wet cleaning, the dust can mix with the water and clog the filters.
• 📱 Settings in the application: activate the moping mode in Mi Home → Cleaning → Settings → Wet cleaning.
• 🚫 Floor Check: Remove carpets (the robot doesn’t wash carpets) and large debris that can damage the napkin.

A critical mistake many users make is pouring water into a tank with a napkin installed, which causes instant wetting of the fabric and failure of the humidity sensors. First fill the tank, then fasten the napkin.

What water can be poured into Xiaomi Vacuum Mop P: requirements and prohibitions

Not all water is suitable for a robot vacuum cleaner, and using the wrong fluid is the main cause of pump failures and plaque formation in the spray system.

Xiaomi's official guidelines only allow pure drinking water (boiled or filtered) and distilled water is also suitable, but it's hard to find in large quantities.

• 🚱 Tap water (contains chlorine and salts that settle in tubes).
• 🧼 Cleaning products (even those special for robot vacuum cleaners – they foam and block sensors).
• ☕ Hot water (can deform plastic parts of the tank).
• 🍋 Acidified water (vinegar, citric acid - corroded by seals).

If you want to disinfect floors, use a special wipe with antibacterial impregnation for robot vacuum cleaners (for example, from Xiaomi or Ecovas). They are attached to the main tissue. Alternatively, add 1-2 drops of chlorhexidine to the water (but no more than 1 time per month).

⚠️ Warning: If white stains remain on the floor after cleaning, this is a sign of using hard water).

Step-by-step: how to pour water into the tank correctly

The refueling process seems simple, but there are hidden details. Follow this instruction to avoid leaks and failures.

1. Remove the water tank. Press the button on the back of the robot (marked by a droplet) and pull the tank up.
2. Remove the tank lid. Turn it counterclockwise. Inside, you'll see a MAX mark (usually 200 ml).
3. Pour water. Use a measuring glass or syringe for accuracy. Exceeding the MAX level causes water to flow through the valve and short circuit control boards.
4. Close the lid. Wrap it clockwise until you click. Make sure the seal ring is not twisted.
5. Put the tank back in. Put it all the way to the end until you hear the snap of the lock.
6. Put a napkin on the bottom panel of the robot with Velcro.

After refueling, run the test mode: in the Mi Home app, select the Cleaning Zone and set a small area (1×1 m) to check the uniformity of the spray.

If the robot refuses to start cleaning with a moping, remove and re-install the water tank - sometimes protection against improper installation works.

Common Mistakes and How to Avoid Them

Even experienced users make mistakes when working with a wet cleaning system, and here are the most common ones and ways to solve them:

• 💧 If you pour more than 200 ml, the robot will either refuse to work or start leaking. Solution: drain the excess, wipe the contacts of the tank with dry cloth.
• 🔄 Late refueling. You need to fill the water just before cleaning, not beforehand. The water evaporates, and after 12 hours the tank will remain air, which will lead to an E10 error (no water).
• 🧽 Using a dirty tank, the residue of water with dust particles turns into mud that clogs the nozzles. Solution: rinse the tank after each cleaning.
• 🔌 Ignore errors. If the robot shows E9 (tank problem), don't try to restart cleaning - check contacts and seals.

E10 error (no water) can occur even when the tank is full, caused by a traffic jam in the system, so to eliminate it, shake the tank slightly before installation or tilt the robot forward for 10 seconds.

⚠️ Warning: If the wipe remains dry after cleaning and the floor is dirty, check the Settings → Spray intensity in the application. The minimum level may be selected (suitable only for laminate flooring).

How to care for a wet cleaning system: cleaning and prevention

Regular care extends the life of the robot and prevents breakdowns. Here's a monthly maintenance checklist:

1. Wash the tank once a week with warm water with a soft sponge. Don't use abrasives!
2. Clean the nozzles. wipe the sprayers with a cotton swab dipped in alcohol (no more than 1 time per month).
3. Check the wipe. Wash it manually at 30°C without bleach. Replace it every 3-6 months.
4. Tank contacts. Rub them with a dry cloth, and oxidation causes communication errors with the robot.

To clean the spray system deeply, use special maintenance kits (e.g. Xiaomi Vacuum Cleaning Kit) that include nozzle brushes and rinse solution. If the robot becomes less sprayable, try to run 50 ml of distilled water with 1 drop of citric acid through the system (then rinse with clean water).

Frequent questions about wet cleaning in Xiaomi Vacuum Mop P

Alternative Refueling Methods: When the Standard Method Fails to Work

Sometimes users are faced with unusual situations where the usual instructions do not help, for example, if the tank is not fixed or the robot does not recognize the water.

If the tank is not inserted before clicking:

1. Check if the lock on the robot's body is bent.
2. Make sure the sealing ring on the tank is not offset.
3. Try inserting the tank at a 10° angle and then press until clicked.

If the robot shows E10 error (no water) but the tank is full:

1. Remove the tank and shake it to remove the air traffic jam.
2. Check the contacts on the tank and in the robot’s nest – they should be clean and dry.
3. Update the firmware through Mi Home (older versions have bugs with sensors).

For the 2022 Vacuum Mop P and later, the self-cleaning function of the tank is available. It is activated in the application: Settings → Service → Cleaning the system. The robot will automatically wash the tubes with distilled water.

💡

Never use metal objects to clean nozzles, it will damage the sprayers. Only plastic or wooden sticks!

Comparison with other Xiaomi models: how the Vacuum Mop P differs from competitors

The wet cleaning system in the Vacuum Mop P has several key differences from other Xiaomi robot vacuum cleaners:

The main advantage of the Vacuum Mop P is that it automatically adjusts the humidity according to the type of floor, and it reduces the spray on the laminate and increases the spray on the tile, and cheap models like Essential don't have this feature, which often leads to overhydration.

Another difference is the removable tank. In the Mi Robot Vacuum-Mop, the tank is built into the case, which makes cleaning difficult. In the Vacuum Mop P, you can wash the tank separately without the risk of flooding the electronic components with water.
