Xiaomi Vacuum Mop P is a smart device that combines dry and wet cleaning. But even such advanced technology requires proper handling, especially when it comes to water supply. Incorrect filling of the tank can lead to leaks, pump breakdowns or poor quality of floor washing. In this article, we will understand how to pour water in Xiaomi Vacuum Mop P without errors, which fluids to use and which are strictly forbidden.
Many users have problems: water doesn't come to the cloth, the device starts to spit with liquid, there's an error on the screen, most often it's the result of incorrect filling of the tank or ignoring the rules of operation, we collected all the nuances from water preparation to maintenance after cleaning.
If you've just unpacked a robot vacuum cleaner or you've been using it for a long time, but you've never really gone into detail, this is the guide for you. There's no general phrases here: just specific steps, technical limitations, and solutions to typical problems.
Preparing a robot vacuum cleaner for pouring water
Before filling the tank, make sure the device is ready for wet cleaning, and skipping this step can cause malfunctions or even damage to electronic components.
First, check that the Xiaomi Vacuum Mop P has a water container (it comes with a different package than a dust collector) and make sure the sealing gum on the tank lid is intact and not deformed, which prevents leaks. If the gum is torn or lost elasticity, it needs to be replaced.
Second, look at the mope nozzle, which is clean and properly mounted on the robot base, and if it's worn or contaminated, the water will be distributed unevenly, leaving the squashes.
- 🔋 Battery Charging: Make sure the robot is at least 20% charged. At low charge, the device can interrupt cleaning and water will remain in the tank, leading to stagnation and odor.
- 🧹 Cleaning the vacuum: Before wet cleaning, empty the garbage container. If it's full, the robot won't be able to effectively combine the vacuum cleaner and the mop.
- 📱 Firmware update: Check in the Mi Home app that the robot has the latest version of the software. Old firmware may have water control bugs.
⚠️ Warning: Never pour water into a robot if it is in a charging station.The liquid can get on the contacts and cause a short circuit.
What water can be poured into Xiaomi Vacuum Mop P
Not all water is equally good for your robot vacuum cleaner, and using the wrong fluid is one of the main causes of pump failures and plaque in the system.
Manufacturer recommends pouring only clean drinking water at room temperature (15-25)°C. Boiled or distilled water is also good, but it is not necessary:
- 🚫 Hot water: Can warp plastic tank parts and damage seals.
- 🚫 Mineral or hard water: Leads to lime plaque formation in tubes and pump.
- 🚫 Soaps and detergents: Except for special fluids for robot vacuum cleaners (e.g. Xiaomi Floor Cleaning Solution). Common detergents foam and clog the system.
- 🚫 Alcohol, vinegar, bleach: Eat plastic and rubber parts, shortening the life of the device.
If you want to use detergent, choose only those certified for robot vacuum cleaners. For example, the original solution from Xiaomi is diluted with water in a ratio of 1:200 (5 ml of detergent per 1 liter of water), Excess concentration will lead to excess foam.
| Type of liquid | Can we use it? | Consequences of violation |
|---|---|---|
| Drinking water (room temperature) | ✅ Yes. | No risk. |
| Distilled water | ✅ Yes. | There are no risks (but no benefits over regular water) |
| Original Xiaomi solution (diluted) | ✅ Yes. | No risk. |
| Soap solution (household detergent) | ❌ No. | Foam, pump clogging, breakdown |
| Hot water (>40°C) | ❌ No. | Deformation of plastic, leakage |
Step-by-step: how to pour water into the tank
Now, let's get to the process. Follow the instructions carefully to avoid mistakes.
- Disconnect the robot from the charging station and flip it (up buttons). Make sure the device is turned off.
- Remove the water container: Press the hold button on the back of the robot and pull the tank over you. It should be easy to separate.
- Open the tank cover: Press the latch (usually on top) and lift the lid. Inside you'll see a mark. MAX — This is the maximum water level.
- Pour the water slowly to avoid splashing. Do not exceed the mark MAX — This is about 200 to 250 ml (the exact volume depends on the model), and the overflow will lead to leaks during cleaning.
- Close the tank lid before you click. Make sure the sealing gum is flat, without skewing.
- Place the tank back into the robot until you hear the snap of the lock, and make sure the container sits tight and doesn't stagger.
After pouring the water, turn on the robot and select wet cleaning mode in the Mi Home app or in the control panel. The device automatically detects the presence of water in the tank and begins cleaning.

⚠️ Warning: If the robot produces a Water tank error (code 10) after pouring the water, it means that the tank is installed incorrectly or the water level sensor is contaminated. Try removing and installing the container again. If the error repeats, clean the sensor contacts with a dry wipe.
Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when pouring water, and here are the most common ones and ways to prevent them:
- 💧 Water overflow: If you pour more than before the mark MAX, The robot will start spitting water or stop cleaning with an error.
- 🔄 Use of dirty tank: If the container is left with old water, it may bloom or form a plaque. After each cleaning, rinse the tank and dry it.
- 🧼 Soap solutions without dilution: Concentrated detergent will clog the pump and tubes. Always follow the dilution instructions.
- 🔌 Pouring water with connected power: This is dangerous! disconnect the robot from charging before any fluid manipulation.
Another common problem is that the robot doesn't spray water during cleaning, and the reasons may be:
- The water in the tank is running out (check the level).
- The sprayer is clogged (clean it with a toothpick).
- The pump is defective (diagnosis is required at the service center).
- In the Mi Home application, dry cleaning mode is selected only.
If the robot has started to leave wet marks or puddles, the most likely problem is the wrong installation of the mopose nozzle or wear of the tank's sealing gum. Check these elements and replace them if necessary.
💡
To prevent water from stagnating in the tank between cleanings, after each use drain the remaining liquid and leave the container open for drying.
How to take care of the water supply system
For the Xiaomi Vacuum Mop P to last a long time, it is not enough to just pour water correctly. You need to regularly take care of all components that come into contact with the liquid.
Weekly care includes:
- 🧽 Washing the water tank with warm water (without detergents!).
- 🧴 Cleaning the sprayer from possible deposits (use a soft brush).
- 🧻 Drying a moping nozzle (wash it manually or in a washing machine at 30)°C without pressing).
Monthly care:
- 🔍 Check the tank's sealing gum for wear and tear, replace it if you lose elasticity.
- 🛠️ Cleaning of the water level sensor (located inside the tank) from a coating with a cotton swab soaked in alcohol.
- 💧 Washing of water supply tubes (if you notice a decrease in the intensity of spraying).
If you use detergent, once every 2-3 months carry out a deep cleaning of the system:
- Pour in the tank solution of vinegar (1 part vinegar to 3 parts water).
- Turn on the wet cleaning mode for 5-10 minutes, then drain the solution.
- Wash the tank and tubes with clean water 2-3 times.
⚠️ Warning: Never use abrasives or hard brushes to clean plastic parts. They leave scratches in which dirt accumulates.

Compatible accessories and spare parts
Over time, the robot vacuum cleaner parts wear out and have to be replaced. The following original and compatible accessories are available for Xiaomi Vacuum Mop P:
| Name of name | Article (original) | When to change | Approximate price, ₽ |
|---|---|---|---|
| Water container (tank) | ZNMS18WM | For cracks or leakage | 1 200–1 500 |
| The tank sealing gum | It's included in the tank. | When elasticity is lost or cracked | 200-300 (as part of the remake) |
| Mope nozzle (rag) | ZNMS18MP | Every 3-6 months (with intensive use) | 400–600 |
| Water filter (if provided) | Depends on the model. | Every 6 months | 300–500 |
When buying parts, pay attention to compatibility with your model. For example, the tank from Xiaomi Vacuum Mop 2 Pro will not be suitable for the Vacuum Mop P due to differences in mounts. Original accessories can be ordered from the official Xiaomi store or from trusted sellers (for example, on AliExpress marked "Original").
If you want to save money, you can buy compatible accessories from third-party manufacturers (for example, Ecovacs or Roborock), but their quality may be inferior to the original, especially for sealing gums - non-original often lose elasticity after 1-2 months.
💡
Using unoriginal moose nozzles can lead to poor water distribution and floor swelling. Original microfiber cloths are better absorbers and evenly distribute moisture.
Alternative ways to pour water (for experienced users)
If you're confident in your skills, you can optimize the water pouring process, or even modify the robot for convenience.
1.Use of distilled water to extend service life
Distilled water leaves no lime-like plaque, so some users pour it instead of the usual, which is especially true in regions with hard water, but there's no evidence that it significantly increases the life of the pump, but the main thing is to flush the system regularly.
Installation of an additional filter
Some models (such as Xiaomi Vacuum Mop 2 Pro) have a removable water filter that traps dirt particles. For Vacuum Mop P, there is no such filter, but you can buy a compatible one (for example, from Roborock). S5 Max) and put it in the tank.
3. Automatic water refueling (for craftsmen)
Some enthusiasts are putting an external water tank and pump into the robot to automatically fill up the liquid during cleaning, but this requires soldering and redesign, which is insecure and can lead to breakdown, and we don't recommend this without experience with electronics.
⚠️ Warning: Any modifications to the robot vacuum cleaner that are not provided by the manufacturer will void the warranty. If you choose to experiment, do so at your own risk.
If you don't have enough tank space, you'd better break it down into zones or buy a second robot for other rooms, which is more reliable than risking damage from homemade improvements.
