Xiaomi Mi Robot vacuum cleaners have long since ceased to be just dry cleaning devices. Wet cleaning is one of the most popular features that allows you to maintain perfect floor cleanliness without daily manual labor. However, many users face problems when first turning on this mode: where to find settings, how to install a cloth, what options to choose for different types of coatings?
In this article, we will discuss all the ways to activate wet cleaning on Mi Robot models (including Mi Robot Vacuum-Mop P, Mi Robot Vacuum-Mop 2 Pro and others), explain how to adjust the humidification intensity, and give practical tips for system maintenance, and also reveal hidden functions that are not written in the official instructions, but which greatly simplify life.
Which Xiaomi Mi Robot models support wet cleaning?
Not all Xiaomi robot vacuum cleaners are equipped with a wet cleaning function. To avoid wasting time, first check whether your model is supported.
- 🔹 Xiaomi Mi Robot Vacuum-Mop P (first model with wet cleaning support)
- 🔹 Xiaomi Mi Robot Vacuum-Mop 2 / 2 Pro / 2 Lite
- 🔹 Xiaomi Mi Robot Vacuum-Mop 2 Ultra (with automatic washing of rags)
- 🔹 Xiaomi Mi Robot Vacuum-Mop T10 / T10+
- 🔹 Xiaomi Mi Robot Vacuum-Mop S10 / S10+
If your model is not on this list, but there was a wet cleaning cloth in the package, check the firmware. It may be hidden and requires an update. Go to Settings → About device → Software update in the Mi Home app.
⚠️ The Mi Robot Vacuum series is a series of robots. 1S, Mi Robot Vacuum 2 and other models without the letter "Mop" in the title do not support wet cleaning!
Preparing the robot for the first wet cleaning
Before you start the mode, you need to properly prepare the device, which will take no more than 5 minutes, but will save you problems in the future.
First, make sure that the water tank is installed. It usually comes with a kit and is attached to the back of the case (under the lid). On Mi Robot Vacuum-Mop 2 Ultra models, the tank is built into the docking station - it does not need to be installed manually.
Secondly, check the cleanness of the water nozzle, which often gets clogged with dust after a long period of downtime, brush it with a toothpick or compressed air, and if you ignore that, the robot will leave a dent or not moisturize the cloth at all.

Finally, choose the right cloth. It's usually a microfiber wipe, but it's better to use it for different coatings.
- 🧼 Laminate / parquet: thin microfiber with low humidity (mode "Weak")
- 🧽 Tile/stone: dense cloth with high absorbency (mode "Mediterior / Strong")
- 🚫 Carpets: wet cleaning is contraindicated (except for models with Carpet Detection function)
How to enable wet cleaning through the Mi Home app
The most convenient way to control is through the official Mi Home app (or Xiaomi Home for newer versions).The interface may vary slightly depending on the robot model, but the overall algorithm is the same.
Open the app and select your robot vacuum cleaner.
- Click on the Cleanup icon (usually at the bottom of the screen).
- Choose Wet Cleaning or Vacuum Cleaning + Wet Cleaning (if you need to combine modes).
- Set the water supply intensity (options: Weak, Medium, Strong).
- Start cleaning with the Start button.
On zoning-enabled models (e.g. Mi Robot Vacuum-Mop 2 Pro), you can select specific wet cleaning rooms.
- Go to the map. → Choice of rooms.
- Check the boxes of the room where you need wet cleaning.
- Turn on the mode and click Clear selected areas.
Weak (for laminate)|Medium (universal)|Strong (for tile)|Combined (vacuum cleaner) + humid)-->
If the app does not have a wet cleaning option, check:
- 🔄 Update the firmware of the robot (in Settings) → About the device).
- 📱 Update the Mi Home app to the latest version.
- 🌐 Make sure the robot is connected to the internet (some features require cloud synchronization).
Activation of wet cleaning from buttons on the body
You don't always have a smartphone on hand, and fortunately, the basic functions are duplicated on the physical buttons of the robot, and most models have this algorithm:
- Make sure the robot is off (press and hold the power button for 3 seconds).
- Pour the water into the tank (up to the MAX mark, but not higher!).
- Attach the cloth to the bottom (it should fit tightly to the base).
- Press the Mop (or Water) button once for weak mode, twice for medium mode, three times for strong mode.
- Start cleaning with the Clean button (or Start).
On the Mi Robot Vacuum-Mop P and Mi Robot Vacuum-Mop 2 Lite, the Mop button may not be present.
- Hold the Spot Clean button for 5 seconds until the water indicator lights up.
- Short press select intensity (the indicator flashes: 1 time - weak, 2 times - medium, 3 - strong).
- Press Clean to start.
⚠️ Warning: If the robot makes beeping sounds after activating the wet cleaning and does not move, check: Water level in the tank (possibly the sensor signals an empty tank) Correct installation of the cloth (it should be fixed with latches). Cleanliness of the water sensor contacts (wipe them with a dry wipe).
Setting the intensity of moisture: what to choose?
Not only does the water supply determine the quality of the cleaning, but the safety of the coating, too strong a mode can damage the laminate or parquet, and a weak one will leave divorces on the tile.
| Type of coating | Recommended treatment | Additional advice |
|---|---|---|
| laminate | Weak. | Use a low-moisture cloth. After cleaning, wipe the floor with a dry wipe. |
| parquet | Weak or off. | It is better to limit yourself to dry cleaning. Wet is allowed only for water-resistant coatings. |
| Tile (ceramics, porcelain) | Medium/Strong. | For old-fashioned contaminants, add 1-2 drops of floor washing products to the water. |
| Natural stone (marble, granite) | Medium. | Avoid acid detergents – they destroy the surface. |
| linoleum | Medium. | Before cleaning, check the joints - if they are not dense, water can leak under the coating. |
The Mi Robot Vacuum-Mop 2 Ultra and S10+ have a function called Water Adjustment, and the robot determines the type of coating and selects the optimal level of humidity, and activates it:
- In the Mi Home app, go to Cleaning Settings → Modes → Autointensity.
- Turn on the switch.
- If necessary, calibrate the sensors (in the same menu).
💡
If the robot leaves a stain on the tile, add 10-15 ml of vinegar (500 ml) to the water, which will remove the lime plaque and give a shine without chemistry.
Common Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes that lead to poor cleaning quality or breakdowns, and here are the most common ones:
- 💧 The maximum level is marked by a line. MAX — Excessiveness leads to leakage and damage to electronics. On pump models (for example, Mi Robot Vacuum-Mop 2 Pro), excess water can cause an error. E5.
- 🧺 Use the wrong rags. The fabric must be made of microfiber with looped pile. Conventional cotton rags wear out quickly and leave the fibers behind.
- 🔋 Cleaning at low battery power. If the charge level is below 20%, the robot may interrupt the process and not return to base. >50%.
- 🚫 Ignoring locking zones. If there are carpets or wires in the room, the robot can wet them. Use virtual walls or no-go zones in the app.
Another common problem is that the robot doesn't wash the floor, even though the water is supplied.
- 🔧 The nozzle is clogged. → Clean it with a needle or compressed air.
- 💦 Low pressure in the pump → Check if the tank cover is tightly closed.
- 🔄 Firmware failure → Restart the robot (hold the power button for 10 seconds).
What do you do if the robot gives you an E3 error? E3 error means a water supply problem.
Wet cleaning system care: extending the life of the robot
To ensure that wet cleaning is always effective, you need to regularly maintain key elements of the system.
- After each cleaning: Pour the remaining water out of the tank. Wash the tank with warm water (no detergents!) Remove the cloth and wash it by hand (machine washing spoils the microfiber).
- Once a week: Clean the water nozzle with a toothpick, rinse the tube (if it is removable) under running water, wipe the water sensors with a dry wipe.
- Once a month: Soak the cloth in a vinegar solution (1:1 with water) for 30 minutes for disinfection. Check the pump condition (on hearing - there should be no extraneous noise).
For models with automatic washing of rags (Mi Robot Vacuum-Mop 2 Ultra, S10+) additionally:
- 🧼 Once every 2 weeks, clean the wash brushes from plaque (use an old toothbrush).
- 🔄 Change the water at the docking station after each cleaning cycle.
- 🚫 Do not use flavored or colored detergents – they can clog filters.
💡
Regular cleaning of the nozzle and pipe increases the life of the pump by 2-3 times. Most of the breakdowns of the wet cleaning system are due to clogging!
