Wet cleaning on the vacuum cleaner Xiaomi: how to turn on and configure the mode

Xiaomi’s robot vacuum cleaners have long since ceased to be just dry cleaning devices.Modern models range from the budget Mi Robot Vacuum-Mop to the flagship DreameBot X30 Ultras are equipped with a wet cleaning function that allows you to vacuum and wash floors at the same time, but many users face difficulties when first turning on this mode: the button is not active in the application, the cloth is not wetted, the robot leaves the divorce. In this article, we will analyze all the ways to activate wet cleaning on different models, typical errors and nuances of settings for the ideal result.

It is important to understand that the switching algorithm depends on the specific model of the vacuum cleaner and the firmware version. For example, in Xiaomi Mi Robot Vacuum-Mop 2 Lite, wet cleaning is configured through the Mi Home app, and in DreameBot, wet cleaning is configured through the Mi Home app. Z10 Pro is made by Dreamehome, and we're going to look at the universal steps, and we're going to look at the features of the popular devices, and if you don't mention your model, the principles will remain the same, only the names of the menu items will differ.

1. Preparation of the vacuum cleaner for wet cleaning: what to do before the first switching on

Before you activate the mode, make sure the robot is physically ready for wet cleaning, and many users miss this stage, which leads to errors or poor quality washing.

• 🔧 Install a water tank. In most models, it comes bundled and mounted instead of (or near) a standard dust collector. S7 and a newer tank combined - for dust and water at the same time.
• 🧼 Prepare a napkin/rag. Use only special microfiber nozzles from Xiaomi - they have the optimal density and do not leave a pile. Conventional rags can clog the pump or damage the mechanism.
• 💧 Pour water (and detergent if supported). Volume depends on the model: for Mi Robot Vacuum-Mop P, 200 ml is enough and DreameBot W10 It can hold up to 400 ml. Do not exceed the maximum level - it is fraught with leaks.
• ⚡ Charge the robot to 100%. Wet cleaning consumes more energy, especially if the Deep Mop mode is on.

Note the type of coating in your home. Xiaomi robots automatically adjust the intensity of the water supply on different surfaces, but some models (like Viomi). V3) Laminate flooring, flooring or long-pile carpet can be affected by excess moisture, and we'll talk about this in the error section.

2.How to enable wet cleaning through the application: step-by-step instructions

The main way to control it is through proprietary applications. Let's look at the algorithm for the most popular models. If your vacuum cleaner is not on the list, look for similar menu items.

For models with the Mi Home app (Mi Robot Vacuum-Mop, S5 Max, S6, S7)

1. Open Mi Home and select your vacuum cleaner from the device list.

2. On the main screen, tap the Cleaning icon (or Clean in English).

3. At the bottom of the screen, a panel with modes will appear.Look for the Wet Cleaning icon (a drop of water) or Mop.

4. Activate the slider or select one of the submodes:

• 🌊 Light Mop – easy moisturizing (for daily cleaning).
• 💦 Standard Mop - Standard Intensity (for noticeable contaminants).
• 🌀 Deep Mop - deep sink (for persistent spots, consumes more water).

5. Press Start or Start Cleaning. The robot will start on a given route, simultaneously dusting and my floor.

For models with Dreamehome (DreameBot) Z10 Pro, D9, W10)

The Dreamehome interface is more advanced, here you can adjust the pressure of the cloth on the floor and water flow:

1. Run Dreamehome and select your vacuum cleaner.

2. Click on the Moika icon (or Mop) in the lower menu.

In the window that opened:

• 📊 Select the Washing Intensity (1 to 3).
• 💎 Activate the Vibration sink (if any in your model) – the cloth will vibrate for better dirt removal.
• 🔄 Adjust the frequency of rinsing the cloth (recommended every 5-10 minutes for severe contaminants).

4. Return to the main screen and press Start.

In the DreameBot models W10 And now there's Automatic lifting of the rag on the carpet. To activate it, go to Settings. → Cleaning regimes → Lift the cloth and turn on the option.

For Viomi models (V2, V3, SE)

Viomi uses its own Viomi Home app, where wet cleaning settings are hidden deeper:

1. Open the application and select a vacuum cleaner.

2. Go to the Cleaning section → Settings → Washing regimes.

3. Select one of the modes:

• 🍃 Eco-washing - minimum water consumption.
• 🏡 Standard – Balance between quality and consumption.
• 🚿 Intensive – maximum water supply (for persistent spots only).

4. Save the settings and start cleaning.

In Viomi. V3 The robot has a unique function of hot sink – the robot heats the water to 40-50°C for better fat removal. To turn it on, activate the option to heat water in the wash settings.

3. How to enable wet cleaning without the application: buttons on the case

Not everyone knows, but most Xiaomi robots can be customized without a smartphone using physical buttons on the case.

• 📵 No Wi-Fi access or application not connected.
• 🔄 You need to quickly start cleaning without unnecessary settings.
• 🛠️ Vacuum Resets Settings After Update.

The algorithm for most models:

1.Make sure the water tank is installed and filled and the cloth is secured.

2. Press and hold the power button (or ON/OFF) during 3–5 seconds before the robot makes a beep.

3. Press Mode (or Mode) briefly once or more times until the wet cleaning indicator (usually a blue or blue LED) lights up.

4. Press Start (or Clean) to start cleaning.

On some models (e.g. Mi Robot Vacuum-Mop 2 Pro), the button combination is different:

Press and hold Home + Mode for 5 seconds.


2. release the buttons after the double beep.




3. Press "Mode" briefly until the water indicator flashes.




4. Press "Start" to start.

If the buttons don’t respond, check:

• 🔋 Battery charge (must be at least 20%).
• 🚫 Is there a lock from children (on some models it turns off physical buttons).
• 🔄 Do you need to reset the settings (click the power supply) + Mode for 10 seconds).

💡

If the robot doesn't respond to the buttons, try disconnecting it from the network for 1 minute, then turning it back on. This will reset the controller's temporary errors.

4.Typical errors and how to fix them

Even with the right setup, wet cleaning can work incorrectly, and we will discuss the most common problems and their solutions.

Pay special attention to the error E5 or E6 (They're model-dependent codes. They're signaling problems with the water supply system:

1. Turn off the vacuum cleaner and remove the tank.
2. Check if the water holes are clogged (use a toothpick to clean).
3. Make sure the sealing gums are in place and not damaged.
4. Reboot the robot (press the power button for 10 seconds).

5 Cleaning and maintenance of the wet cleaning system

For a robot to last, regular maintenance is essential, and neglecting to clean leads to pump breakdowns, leaks, and poor cleaning quality.

What to clean and how often:

• 🧽 Water tank: wash after each cleaning, disinfect once a week (you can use a vinegar solution 1:10).
• 🧻 Microfiber cloth: hand-wash after 2-3 cleanings (not in the washing machine!) Dry naturally, without pressing.
• 🔧 Pump filter: check once a month, wash under running water when clogged.
• 🚰 Water supply tubes: blow with compressed air (for example, a hairdryer) every 3 months.

How to clean the pump (if the water does not come):

1. Remove the water tank and find a small hole on the side (usually covered with a stub).
2. Carefully insert a toothpick or needle into it to remove possible blockages.
3. Rinse the tank with warm water and check if the water flows freely through the nozzle.
4. Install the tank back and run the test wash mode.

For models with self-cleaning rags (e.g. DreameBot) W10) additionally:

• 🧼 Once a week, clean the rinse station of scale (use citric acid).
• 🔄 Check the drain hose for inflections - this is a common cause of errors.

💡

Using unoriginal detergents or too concentrated solutions leads to foam formation, which can damage the pump. Dilute the product with water in a ratio of 1:100.

6. Comparison of wet cleaning modes on different models

Not all Xiaomi robots are equally effective in wet cleaning, and we tested several popular models and compiled a comparison table.

If you need a deep cleaning (for example, to remove persistent spots), pay attention to models with a vibration sink (DreameBot). Z10 Pro or hot water (Viomi) V3). For small apartments, a budget Mi Robot Vacuum-Mop 2 Lite is suitable, but note that it does not cope with severe pollution.

For houses with carpets, it is better to choose a robot with the function of auto-lifting a rag (DreameBot). W10, Xiaomi S7). This will prevent carpets from getting wet and prolong their service life.

7 Tips for the Perfect Wet Cleaning

To make the result happy, and the robot lasted longer, follow these recommendations:

• 🧹 Pre-dry cleaning. Before wet cleaning, run the vacuum cleaner in vacuum only mode to remove large debris. This will prevent clogging of the cloth and improve the quality of the washing.
• 🌡️ Water temperature: If your model supports heating (e.g. Viomi) V3), Use it for greasy stains. For delicate coatings (laminate flooring, flooring), it is better to wash it with cold water.
• 🕒 Cleaning time: It's optimal to run the robot when you're not home, but not for more than 2 hours.
• 🧴 Cleaners: Use only specialized robot vacuum cleaner fluids (e.g. Xiaomi Mop Detergent) and regular floor cleaners can foam and damage the mechanism.
• 🗺️ Zoning. In the app, mark areas where wet cleaning is needed and exclude carpets or rooms with delicate coatings.

For DreameBot owners W10 And similar models with a self-cleaning station:

• 🚿 Once a month, wash the station with a solution of citric acid (1 tbsp. spoon per 1 liter of water) to remove scale.
• 🔄 Watch the water level in the main tank of the station – if it is below the minimum, the robot will not be able to rinse the cloth.

💡

If the robot leaves stripes on the laminate, add 1-2 drops of glass washing (without ammonia) to the water, which will reduce friction and improve the rag's slip.
