How to set up a Xiaomi robot vacuum cleaner for wet cleaning through the Mi Home app: the full guide

Why wet cleaning in Xiaomi robots requires special adjustment

Xiaomi’s wet cleaning robots are not just dust-collecting devices, but full-fledged clean-up assistants. However, many users find that the device either does not clean floors well, leaves divorces, or ignores the wet-cleaning command altogether. The reason lies in the wrong settings through the Mi Home app — without a competent configuration, even top-end models like the Xiaomi Robot Vacuum-Mop 2 Pro or the DreameBot Z10 Pro work at 30% of their capabilities.

In this article, we'll look at all the steps of the setup, from basic connectivity to subtle parameters that the manufacturer doesn't advertise, how to choose the optimal cleaning mode for laminate, tile or parquet, why the robot can refuse to wash certain areas, and how to get it to waste water economically but efficiently, and also unique life hacks for calibrating moisture sensors that are not described in the official documentation.

Important: the instruction is relevant for all modern models of Xiaomi with support for wet cleaning (the Mi Robot Vacuum-Mop series, DreameBot, Viomi, etc.), but some menu items may differ slightly depending on the firmware version.

Preparing the robot for the first wet cleaning: what to do before setting up in Mi Home

Before you climb into the app, make sure the robot is physically ready for wet cleaning, and skipping this stage is the main cause of pump failures and water leaks.

• 🔋 Charging to 100%. Wet cleaning consumes on 20-30% More energy than dry. If the charge is lower 80%, The robot can interrupt the process or reduce the intensity of washing.
• 💧 Check the water tank. Make sure the container is clean (no mold or plaque) and the sealing gum is intact. S7 And the newer tank has a water level sensor -- if it's contaminated, the robot will make an error. E12.
• 🧽 Installation of a napkin. Use only microfiber fabrics with a density of at least 250 g/m2. Synthetic or terry wipes clog the pump and leave the pile on the floor.
• 📏 If the robot "does not reach" the floor (for example, on a high carpet), wet cleaning will be ineffective. → Service → Calibration of height, choose the optimal gap.

⚠️ Warning: Never use detergents with foam or aggressive surfactants (such as Fairy or Freshwater). AOS). They destroy the rubber pump seals and leave the film on the sensors, and only specialized fluids for robot vacuum cleaners (for example, Xiaomi Mi Robot Detergent) or diluted vinegar (1:10) are allowed).

After physical training, move to the Mi Home connection. If the robot has already been added to the app, skip the next section.

Connecting the robot to Mi Home: step-by-step instructions with pictures

If you've just unpacked the device, the first thing you need to do is tie it to your Mi Home account, which takes no more than 5 minutes, but there are nuances that aren't written about in the official manual.

1. Download the Mi Home app (at least 6.5.4) from Google Play or the App Store. Older versions may not support newer robot models.
2. Register an account or log in via Xiaomi ID. For Russia, choose the region Russia, for other countries - corresponding to your location (this affects the available features!).
3. Add the device: Press + → Add the device → Household robot. Select your model from the list (if not, try Another → Household robot). Hold the Reset button (or Power + Home in models without a separate reset button) on the robot body for 3-5 seconds until you hear the beep.

Once you've successfully connected, the robot will appear in the app's main menu. If the process is stuck in the Connection phase, try:

• 🔄 Reboot the router (sometimes) DHCP fails IP robot).
• 📶 Switch to 2.4 GHz (5 GHz not supported!).
• 📱 Shut down. VPN or a proxy on the phone.

⚠️ Note: If after connecting in the application Cyrillic is displayed by Krakozabras (for example, "ÐобоÑ"), Change the language of the phone system to English, restart Mi Home, then return Russian.

Wet cleaning setup: the main parameters in Mi Home

Now, to the most important thing, the wash mode configuration. Open the robot card in Mi Home and go to Settings → Cleaning Modes (or Cleaning Settings in English). Here we are interested in 4 key parameters:

Pay special attention to setting up the wet cleaning schedule, the optimal time is when no one is home (for example, from 10:00 to 16:00), but at the same time:

• 🌡️ The temperature in the room is not lower than 18°C (otherwise, water will evaporate too slowly).
• ☀️ No direct sunlight on the wet floor (may cause deformation of the laminate).
• 🔌 Robot is connected to base (if the charge is below 50%, it will not start wet cleaning).

Laser scanning (LiDAR) models have Room Cleaning, which allows you to use wet cleaning for specific rooms, such as washing the kitchen daily and the bedroom once every 3 days.

💡

If the robot leaves stripes on the laminate, reduce the washing intensity to Low and add 1 tbsp of vinegar to 1 liter to the water. This will reduce the surface tension of the water and improve the slip of the wipe.

Hidden settings: how to turn on expert wet cleaning mode

The standard Mi Home interface has several important options that can be activated through the developer menu or alternative firmware. For example, DreameBot models have an undocumented Deep Mop Mode feature that increases the pressure of the wipe on the floor to remove dried spots.

To access hidden settings:

1. Open the robot card in Mi Home.
2. Click 5 times in a row on the firmware version (in the About section). the message will appear "Developer Mode activated".
3. Return to the main menu – now a new option will appear in Settings Additional (Advanced).

In expert mode, you can:

• 📊 Set up the humidity sensor calibration (useful if the robot pours too much/little water).
• ⚙️ Change the motion algorithm when wet cleaning (for example, enable Y-shaped instead of the standard S-shaped for better corner coverage).
• 🔄 Turn off automatic lifting of the wipes on the carpets (if your carpets are washed).

⚠️ Attention: Changing settings in developer mode can cause firmware to crash. Before experimenting, back up your settings through Settings → Backup: In case of “bricking” the robot will need to flash through Mi Home in manual mode (instructions are in the official forum Xiaomi).

Typical Problems and Solutions: Why a Robot Does Not Wash the Floor

Even after you set it up properly, wet cleaning can malfunction, and here are the most common symptoms and their causes:

If the robot beeps and flashes red when trying to start wet cleaning, check:

• 🔌 Is the water tank connected (in Xiaomi models) S5 and older have a tank presence sensor).
• 🧼 Is the sleeve properly fitted (it should lie flat, without folds).
• 📱 Is the firmware updated (in the old versions there was an error with the recognition of the wash mode).

To diagnose the exact cause, open the Cleanup Log in Mi Home, which lists the error codes and the time they occurred.

💡

If the robot starts wet cleaning, but stops after 5 minutes, check the battery settings in Settings → Power. It may have a saving mode that blocks intense tasks.

Water consumption optimization: how to save and not lose

One of the biggest fears of robot vacuum cleaners is that they're running out of water, and on average, a 200-300 ml tank can last 40-60 m2, but if you're not setting it right, it can run out of 20 m2.

1. Set up areas of varying intensity: High intensity for the kitchen (high pollution), low or medium intensity for the bedroom (dust), medium intensity for the corridor (sand, dirt from shoes) medium + double aisle.

Use the Eco mode.

Turn off wet cleaning on carpets

Check your napkin after each cleaning.

For models with a self-cleaning base (for example, Xiaomi S7 MaxV Ultra), the Water Refill feature is available - the robot automatically pours water from the tank into the tank during cleaning. This is convenient for large areas, but increases the total cycle time by 20-25%.

Average water consumption depending on the regime:

• 💧 Low intensity: 0.03 l/m²
• 💧 Average intensity: 0.05 l/m²
• 💧 High intensity: 0.08 l/m²

💡

To check the actual water consumption, weigh the tank before and after cleaning on a kitchen scale. The difference in grams = the amount of water consumed (1 g ≈ 1 ml).
