Wet cleaning in Xiaomi robot vacuum cleaners: how to start and configure correctly

Xiaomi’s wet cleaning robots have become indispensable tools for cleaning the house, combining dry cleaning with a water tank, but many users have difficulty first running the mod: where to find settings, how to install a napkin, and why the robot sometimes ignores the wet cleaning command. In this article, we’ll look at everything from device preparation to the intricacies of the Mi Home app.

It is important to understand that not all Xiaomi models support wet cleaning. For example, budget versions like the Mi Robot Vacuum-Mop P are equipped with this feature, while basic vacuum cleaners (for example, the Mi Robot Vacuum 1S) can only work in dry cleaning mode. We will focus on current models with a hybrid system, such as the Xiaomi Robot Vacuum-Mop 2 Pro, DreameBot D9 and others where wet cleaning is implemented at the hardware level.

If your Xiaomi robot vacuum cleaner is ready to go, but you don't know how to turn on floor washing, don't worry. It only takes a few minutes, but it requires attention to detail, from the water level in the tank to choosing the appropriate mode in the application. Next, you'll find a step-by-step instruction with key illustrations, a model compatibility table, and answers to frequent questions.

Which Xiaomi models support wet cleaning?

Before you try to activate the floorwashing mode, make sure your Xiaomi robot vacuum cleaner model is technically capable of doing so. The manufacturer divides the devices into three categories:

• 🔴 Dry cleaning only: Mi Robot Vacuum 1/1S/1C, Mi Robot Vacuum E10 — In these models there is no water tank and fastening for a napkin.
• 🟡 Hybrid (dry) + Wet: Mi Robot Vacuum-Mop P, Xiaomi Robot Vacuum-Mop 2 Pro, DreameBot D9/L10 — equipped with a removable water tank and electronic control of moisture supply.
• 🟢 Advanced washing systems: Xiaomi Robot Vacuum-Mop 2 Ultra, DreameBot X30 Ultra – with automatic lifting of the napkin, intensity adjustment and drying function.

To determine the capabilities of your device, check:

1. The presence of a removable water tank on the back or top panel of the robot (usually marked in blue).
2. A button or Mop indicator (napkin) on the case or in the application.
3. Mention of the function of "wet cleaning" in the characteristics of the model on the official website of Xiaomi.

If your device is not on the list of hybrid or advanced models, attempts to start wet cleaning software (through the application) will lead to an error. In this case, consider upgrading or buying accessories from third parties (for example, magnetic holders for wipes), but note that such solutions do not guarantee proper operation and can damage the robot.

Preparing a robot vacuum cleaner for wet cleaning

Before the first start of the washing mode, several mandatory steps must be taken. Neglecting the preparation can lead to leaks, damage to flooring or breakage of the device.

Installation of a water tank and napkin

• 💧 Pour water into the tank before marking MAX (Use only clean water at room temperature; detergents cannot be added).
• 🧼 And you can attach the napkin to the bottom of the robot, and it should fit tightly into the magnetic holders, without folding.
• ⚠️ Check the tank mount, it should be fixed with a characteristic click. If the tank is installed incorrectly, the robot will not start cleaning.

2.Selection of a napkin

Use only special wipes for robot vacuum cleaners (for example, original from Xiaomi or compatible from Dreame).

• 🧹 Clog the water supply system.
• 💦 Leave divorces on the floor.
• 🔧 Lead to errors in humidity sensors.

Tip: if you have laminate or parquet, reduce the intensity of the water supply in the application settings (Water Volume option). For tiles or linoleum, you can set the maximum level.

Step-by-step: how to start wet cleaning

The process of activating the washing mode depends on the robot model and the firmware version, and we will look at two main ways: through the Mi Home app and using physical buttons on the case.

Method 1: Through the Mi Home app

1. Open Mi Home and select your robot vacuum cleaner from the device list.
2. Go to Cleaning (or Clean in English).
3. Click on the Mop icon (napkin) or select Mop Only or Vacuum & Mop.
4. Set a cleaning area (if needed) and press Start.

Method 2: With buttons on the robot

Some models (for example, DreameBot D9) have a separate Mop button.

1. Hold the Mop button for 2-3 seconds until the blue light light lights up.
2. Press the Clean button to start cleaning.

Important: If the robot starts cleaning, but the napkin remains dry, check:

• 🔌 Water supply pump - when clogging or breakage, water does not enter the napkin.
• 📱 Settings in the application - perhaps selected only vacuum (Vacuum Only) mode).

Wet cleaning settings in the Mi Home app

The Mi Home app allows you to fine-tune the floor washing options. Consider the key options available for most wet cleaning models:

For models with memory card support (for example, Xiaomi Robot Vacuum-Mop 2 Pro), you can save separate settings for different rooms, for example, in the kitchen, set high water levels, and in the bedroom – low.

💡

If the robot leaves a squash on the floor, reduce the Water Volume by one division and add 1-2 drops of glass washing (no more!) to the water.

Common mistakes and their solution

Even with the right setup, users face problems with wet cleaning, and let's look at typical situations and how to fix them.

⚠️ Note: If Xiaomi robot gives an error Mop System Error (code 12 or 14), immediately turn it off and check it:

• 🔧 Integrity of the water tank (cracks or loose fittings).
• 💧 Clean pump filter (can be clogged with lime plaque).
• 📲 The relevance of firmware (in older versions, bugs with sensors are possible).

Another common problem is that the robot forgets to turn on the wet cleaning after the software update.

1. Reboot the robot (hold the power button for 10 seconds).
2. Reset the cleaning settings in the Mi Home app to factory.
3. Update the firmware manually through Settings → Software update.

💡

If the Xiaomi robot vacuum cleaner ignores the wet cleaning areas, check if the map settings conflict with the No-Mop Zones settings (areas where washing is prohibited).

Tips for Effective Wet Cleaning

To make the most of the capabilities of a robot vacuum cleaner with a floor washing function, follow these recommendations:

• 🕒 Cleaning schedule: Set up automatic cleaning for times when you're not home (e.g. during the day) to allow the robot to operate without interference.
• 🧽 Clean the napkin: Wash it after each cleaning under running water and dry it straightened. Replace the napkin every 2-3 months.
• 🚫 No-go zones: In the Mi Home app, mark areas where wet cleaning is undesirable (carpets, flooring without protection).
• 🔄 Alternating modes: For best results, start dry cleaning first, and then wet cleaning.

For models with hot water function (for example, DreameBot X30 Ultra):

• Use the heating mode only for severe contaminants (frequent use shortens the life of the pump).
• After cleaning, drain the remaining water from the tank to avoid scaling.
