Why does Xiaomi’s wet cleaning work differently than you expect?
You bought a Xiaomi robot vacuum cleaner with wet cleaning function, connected it to the Mi Home or Dreamehome app, but you couldn't get it to clean the floors properly? Or maybe the mode turns on, but the wipe remains dry and the laminate is left with scuffs? 90% of the time the problem is not the device's breakdown, but the wrong settings or the nuances of the system.
In this article, we will analyze the unique features of wet cleaning on Xiaomi robots - from the budget Mi Robot Vacuum-Mop P to the flagship DreameBot. X30 You will learn exactly how the mode is turned on, what settings are responsible for the intensity of the washing, why the robot can ignore wet cleaning in some areas and how to avoid spoilage of flooring. And also – a secret trick with the calibration of the humidity sensor, which is not written in the official instructions.
Spoiler: If your robot refuses to wash floors, 7 out of 10 cases are to blame for an improperly installed water tank or clogged liquid supply valve.
Which Xiaomi models support wet cleaning?
Not all Xiaomi robot vacuum cleaners can wash floors, but the wet cleaning feature only appeared in models with a separate water tank and a special wipe. Here are the key series that support this mode:
- 🔹 Mi Robot Vacuum-Mop (P, 2C, 2S, 2 Pro, etc.) – budget models with basic wet cleaning.
- 🔹 DreameBot (D9, L10, W10, X30 Ultra – Advanced robots with wash intensity adjustment and wipe self-cleaning.
- 🔹 Viomi V2/V3 — models with hot water and disinfection support.
- 🔹 Xiaomi Mi Robot Vacuum X10+ — flagship with automatic napkin change.
If your model is not on this list, check the specifications on the official website or in the application. 1S Mi Robot Vacuum E10 They don’t support wet cleaning – they don’t have a water tank.
Preparing a robot for the first wet cleaning: 5 mandatory steps
Before you turn on the moping mode, make sure the robot is ready to go, and skipping at least one of these steps can cause water leaks, damage to flooring, or device failure.
- Set up a water tank. It should be tightly fixed on the base of the robot. If the tank wobbles or doesn't get up until you click, check if there's any debris or damage inside.
- Put a napkin in. It should be special for robot vacuum cleaners (a regular cloth won't work!) The napkin needs to be straightened and fixed to a plastic platform.
- Pour water (or detergent) and use only distilled or boiled water to avoid the swelling. MAX tank-house.
- Check the water supply valve. It's at the bottom of the tank. If the valve is clogged, the robot won't be able to wet the napkin.
- Update the firmware. Outdated software can block the wet cleaning function. The update is available in the Mi Home or Dreamehome app.
☑️ Checking before wet cleaning
⚠️ Warning: Never use hot water or aggressive detergents (such as bleach or bleach) for wet cleaning, which can damage the robot's internal tubes and void warranty.
How to enable wet cleaning through the application: step-by-step instructions
The most reliable way to activate the moping mode is through the official app. The interface may vary slightly depending on the model, but the general logic is the same.
For robots Mi Robot (Mi Home app):
- Open the Mi Home app and select your robot.
- Click on the Cleanup icon (usually at the bottom of the screen).
- Select Wet Cleaning or Vacuum Cleaning Mode + Mope.
- Set the water supply intensity (if there is such a slider).
- Start cleaning with the Start button.
For DreameBot robots (Dreamehome app):
- In the Dreamehome app, tap on the robot.
- Select Cleaning Modes → Moping.
- Set the water level (from weak to maximum).
- If necessary, activate the Deep Clean option (for persistent contaminants).
- Press Start.
If the app does not have a wet cleaning option, check:
- 🔌 Is the water tank connected (the robot automatically detects it).
- 📱 Is the application updated to the latest version.
- 🌐 Is the robot connected to the Internet (some settings require cloud synchronization).
💡
If the robot ignores wet cleaning in some rooms, check the no-go zones in the cleaning map. You may have accidentally added a puping restriction in the settings of the room.
Setting the intensity of wet cleaning: what do water levels mean?
Mi Home and Dreamehome have a slider or water intensity switch, but what exactly do these levels mean and how do you use them properly?
| Water level | Expenditure (ml/min) | For which surfaces | Recommendations |
|---|---|---|---|
| Weak (Low) | ~10–15 ml/min | Laminate, parquet, vinyl | Use it for delicate coatings. The napkin will be slightly wet. |
| Medium (Medium) | ~20–25 ml/min | Tile, linoleum, marble | Optimal mode for most sexes, well removes dust and light contaminants. |
| Strong (High) | ~30-40 ml/min | Porridge, porcelain, concrete | Suitable for persistent stains, but can leave divorces on glossy surfaces. |
| Maximum (Max) | ~50+ ml | Only for very dirty floors. | Use rarely! Excessive moisture can leak under the boards or damage the coating. |
⚠️ Attention: DreameBot robots X30 Ultra and Viomi V3 It's called "Water Auto-Regulation," and it's called "Water Auto-Regulation," and it's a mode where it can determine the type of coating and the intensity, but sometimes it's wrong, like taking the laminate for the tile.
If after cleaning there are divorces or the floors dry for a long time, try:
- 💧 Reduce water levels by 1-2 divisions.
- 🧼 Use special detergents for robot vacuum cleaners (they reduce foaming).
- 🔄 Turn on Double Pass mode (if there is in the settings) - the robot will walk in one place twice, better collecting moisture.
Wet cleaning problems and their solutions: why doesn't a robot wash the floor?
Even if you set it up correctly, the robot may refuse to wash the floors, and here are the most common reasons and ways to eliminate them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Robot doesn't wet a napkin | Clogged water supply valve or tube | Wash the tank under running water, clean the valve with a needle |
| Water doesn't go into the napkin. | Incorrectly installed tank or napkin | Remove and install the tank again, check the fixation of the napkin. |
| The robot doesn't clean all rooms. | Cleaning map configured zones for the ban on moping | Open the map in the application and check the settings of the rooms |
| After cleaning, there are puddles left. | Too high water level or clogged drain | Reduce the intensity, check the drainage holes |
| Robot makes strange sounds when moping | The pump got air or debris | Turn off the robot, drain the water, flush the tank. |
If none of these things worked, try resetting the robot to the factory.
- Press the power button on the robot for 10 seconds.
- Wait for the beep (usually two short beeps).
- Connect the robot to the app again.

Secret functions of wet cleaning: what is not written in the instructions
Manufacturers rarely talk about the hidden capabilities of robot vacuum cleaners, and here are some tips to help make wet cleaning more efficient:
- 🔄 Y-shaped cleaning mode, which is enabled in the map settings (if the robot supports laser navigation), and the robot moves not chaoticly, but along clear lines, better processing the floor.
- 💦 Calibrate the humidity sensor. If the robot is bad at detecting water levels, recalibrate: in the app, find Settings for the water level. → Sensors. → Resetting calibration.
- 🧹 Hybrid vacuum cleaner mode + Mop. On some models (e.g. DreameBot) X30 Ultra) can be configured to clean: first vacuum cleaner, then moping or vice versa.
- 📍 Priority cleaning areas: In the app, you can highlight areas where the robot will wash the floor more intensively (for example, near the front door).
Another life hack: if your robot supports voice control (via Alice, Google Assistant or Siri), you can start a wet cleaning with your voice.
Alice, start the robot vacuum cleaner in mid-intensity moping mode.⚠️ Attention: On Viomi robots V3 and DreameBot W10 There's a self-cleaning wipe function, but if you use it too often, the washing unit can clog up. We recommend cleaning the napkin manually under running water every 3 to 5 times.
💡
On robots with a wipe self-cleaning function (for example, DreameBot) X30 Ultra) never use conventional detergents, only special fluids for robots. Otherwise, the foam will clog the cleaning system.
Frequent User Mistakes: What Not to Do When Cleaning Wet
Many Xiaomi robot vacuum cleaner owners make the same mistakes that lead to breakdowns or poor cleaning quality.
- 🚫 Use regular rags. They don't fix on the platform and can clog the robot's brushes.
- 🚫 Pour water above the mark MAX. This leads to leaks and breakage of the pump.
- 🚫 Leave the robot with water for a long time, and if you don't drain the water after cleaning, you get mold inside the tank.
- 🚫 Wash the robot under running water. You can only wipe the napkin and the tank!
- 🚫 Use the robot on carpets in a moping mode. Wet cleaning is only for hard surfaces.
Another common mistake is ignoring firmware updates, where manufacturers regularly release patches that improve wet cleaning algorithms, such as the updated firmware for Mi Robot Vacuum-Mop 2 Pro that added support for zonal cleaning with varying water intensity.
If you bought a robot vacuum cleaner Xiaomi used, be sure to:
- Wash the vinegar water tank (1:1 with water) for disinfection.
- Check the condition of the napkin and brushes - they could wear out.
- Reset the settings to factory (to remove old cleaning cards).
