How to enable wet cleaning on the robot vacuum cleaner Xiaomi Mi: detailed instructions with nuances

Xiaomi Mi vacuum cleaners are no longer just smart brooms — modern models can not only collect dust, but also clean floors. However, the wet cleaning function often goes unclaimed: users either do not know how to activate it correctly or face errors when they first start. In this article, we will analyze all the ways to connect wet cleaning, from the basic settings in the Mi Home app to solving typical problems with a water tank and wipes.

It is important to understand that the switching algorithm depends on the model of the robot: the Xiaomi Mi Robot Vacuum-Mop P process is different from the Mi Robot Vacuum-Mop 2 Lite, and flagship versions like Xiaomi Mi Robot Vacuum-Mop 2 Ultra require additional calibration of humidity sensors. We have collected universal instructions taking into account the characteristics of different generations, and added a table of compatibility accessories and a list of errors that can occur during the configuration.

What Xiaomi Mi models support wet cleaning

Not all Xiaomi robot vacuum cleaners can wash floors, but the wet cleaning feature only appeared in the Mop hybrid models in the title, and here are the key series that support this option:

• 🔹 Xiaomi Mi Robot Vacuum-Mop (first generation, 2019) – basic model with a water capacity of 200 ml.
• 🔹 Xiaomi Mi Robot Vacuum-Mop P - improved version with electronic water supply control.
• 🔹 Xiaomi Mi Robot Vacuum-Mop 2/2 Pro/2 Ultra – flagship models with automatic lifting of napkins and drying function.
• 🔹 Xiaomi Mi Robot Vacuum-Mop 2 Lite – budget option without a laser rangefinder, but with wet cleaning.

If your model is not included in this list, but there is a water tank in the kit, check the name in the Mi Home app. Sometimes the manufacturer releases regional versions with other indices (for example, Mi Robot Vacuum-Mop Essential for the European market).

⚠️ Note: Robots without the Mop console (for example, Xiaomi Mi Robot Vacuum) 1S) They can't physically do wet cleaning -- they don't have napkin mounts and water containers. Attempt to attach a mop cloth to such models may damage the device.

What you need for wet cleaning: equipment and accessories

Before you start the first wet cleaning, make sure you have everything you need. Most models come with a standard set of:

• 📦 Water tank (usually 200-300 ml) with a lid and filter.
• 🧹 Mop napkin (microfibre or cotton, depending on the model).
• 🔧 Fixing for a napkin (plastic or metal plate on the bottom of the robot).
• 💧 Water dosing nozzle (in electronically controlled models).

If any of the elements are missing, check the box for additional compartments or buy accessories separately. For example, for Xiaomi Mi Robot Vacuum-Mop 2 Ultra, only original wipes with magnetic mounts will work, and for budget models you can use universal ones.

Important: Do not use wipes from other brands unless they are certified for your model. Cheap analogues can damage moisture sensors or leave stains on the floor due to improper fabric structure.

Step-by-step: how to connect wet cleaning in Mi Home

The activation of the wet cleaning function takes place in two stages: physical training of the robot and in-app tuning. Let's look at both in detail.

Installation of a water tank and napkin

Make sure the robot is off and is on base |Remove the dust collector and install a water tank |Put water into the container (not higher than the maximum mark) |Affix the napkin to the mount on the bottom |Check the density of fixation of all elements-->

First, disconnect the robot from the power supply and remove the main dust collector, install a water tank in its place, it should click with a characteristic sound, pour distilled or boiled water into it (a regular tap water can contain impurities that will clog the system), make sure that the liquid level does not exceed the MAX mark.

Next, attach the napkin:

1. Spread it on a flat surface.
2. Apply to the mount on the bottom of the robot (for models with Velcro – tightly press, for magnetic – combine with connectors).
3. Make sure that the napkin does not hang and does not interfere with the movement of the wheels.

2. Setup in the Mi Home app

Open the Mi Home app, select your robot vacuum cleaner and go to Cleaning Settings (or Cleaning Settings in English).

1. Click on the Mopping (Wet Cleaning) tab.
2. Activate the slider Enable wet cleaning.
3. Select the water supply intensity (if the model supports adjustment): 🌊 Low - for laminate and parquet. 🌊🌊 Medium - for tile and linoleum. 🌊🌊🌊 High - for severe contaminants (only for water-resistant coatings!).

Just washing.

Mop Only

In models Xiaomi Mi Robot Vacuum-Mop 2 Pro/Ultra option is additionally available Automatic lift napkin - it allows the robot to lift the mop when moving on carpets, so as not to wet them.

💡

If the app does not have the Wet Clean tab, update the robot firmware. Go to Settings → About device → Software Update and install the latest version.

Typical errors and their solution

Even after the right setup, the robot can make mistakes or refuse to wash the floor, and these are the most common problems and ways to fix them:

• ❌ No Water error - check: Is the water tank lid closed (the sensor only works when closed tightly) Is the tank empty (sometimes the water level sensor falsely works when less than 50 ml of fluid remains) The clarity of the sensor contacts (wipe them with a dry wipe).
• ❌ The robot doesn't wash the floor, but the water goes away -- possible causes: a wipe is not properly secured or torn. A clogged water supply tube (must be washed under running water) In models with an electronic pump (Vacuum-Mop). P/2 Pro) calibration may have been lost - settings reset required.
• ❌ After cleaning, there are divorces - try: Use distilled water instead of tap water. Add 1-2 drops of floor washing products (only if this is allowed in the instructions!). Replace a tissue with a denser one (for example, with the High Absorption marking).

⚠️ Warning: If the robot starts making beeping noises during wet cleaning and stops, it's a sign of overheating the pump. Immediately turn off the device, drain the water and let it cool for 30 minutes.

Additional settings for advanced users

If you want to maximize the efficiency of wet cleaning, take advantage of these tips:

• 📍 Zoning: In Mi Home, you can create virtual zones where the robot will only wash the floor (for example, the kitchen and the corridor), and in other rooms - only vacuum. → Edit → Add a zone and select the washing only mode.
• ⏱️ Cleaning schedule: Set up automatic wet cleaning for a time when you are not at home, optimally 1-2 hours after dry cleaning, so that the dust does not have time to settle again.
• 🔄 Alternating modes: Vacuum-Mop 2 Pro models have a First vacuum mode, then wash mode – this prevents dirt from being smeared on the floor.

For owners of Xiaomi Mi Robot Vacuum-Mop 2 Ultra, the option Hot Water (if the heating module is connected) is available, activates it in additional cleaning settings and allows you to better wash out greasy stains, but increases energy consumption by 20-30%.

💡

Rinse the water tank and water supply tubes under running water regularly (every 1-2 weeks) to prevent the formation of lime plaque that can disable the pump.

Comparison of wet cleaning on different models Xiaomi Mi

To understand whether to overpay for top models, compare the key parameters of wet cleaning in different series:

As you can see from the table, the basic models are suitable for small apartments with laminate or tiles, and the top ones will pay off in homes with different types of coatings and a large area. For example, Mi Robot Vacuum-Mop 2 Ultra washes and dries a napkin on the base, which eliminates manual care.
