How to put wet cleaning on a robot vacuum cleaner Xiaomi

The inclusion of wet cleaning on Xiaomi robot vacuum cleaners is often a question for users, as the process depends not only on the software, but also on the physical configuration of the device. Many owners mistakenly believe that it is enough to simply install a water tank for the robot washer to start working, but navigation algorithms require accurate calibration.

Modern models such as Xiaomi Vacuum-Mop 2 Pro or Mijia 1C use intelligent zone recognition systems, which requires preliminary preparation of a room map. Without performing a number of preparatory steps in the Mi Home or Xiaomi Home application, the launch of the washing mode can be blocked by the security system. In this article, we will discuss in detail all the steps necessary to activate and optimize the process of floor washing.

Verification of compatibility and completeness of the device

The first step before trying to set up a wet cleaning is to make sure that your device is physically capable of doing this. Not all Xiaomi robot vacuum cleaner models support floor washing; some are designed exclusively for dry cleaning and do not have the appropriate connectors or sensors. If the package did not have a module with a water tank and a cloth, software activation of the function will not be possible.

It's important to distinguish the original components from the third-party ones, because the contact groups at the bottom of the original tank can have a specific configuration. The robot reads the presence of the module through these contacts, and if they are absent or incorrectly connected, the system will block the start of the wash mode. Visually check the bottom of the tank: there must be metal pads or magnets that correspond to the response part on the robot body.

• 🤖 Availability of a special tank-bucket with a water supply valve in the kit.
• 🤖 Presence of microfiber wipe or platform for fastening the cloth.
• 🤖 The absence of the main dust collector (often interchangeable).
• 🤖 Support for the function in the application (drop icon or Mop inscription).

⚠️ Note: Using homemade water tanks or unoriginal tanks without electronic controllers can lead to short circuit and failure of the robot.

Physical installation of the wet cleaning module

The process of installing a wet cleaning module requires precision and a certain sequence of actions. First, you need to remove the main container for collecting dry dust, since the simultaneous installation of two containers is structurally impossible. Then a water tank is installed in the vacant compartment, which must be latched to a characteristic click, providing reliable electrical contact.

Once the tank is fixed, the floor surface must be prepared, a special microfiber wipe is attached to the bottom of the module, and the use of ordinary cotton rags or fabrics with a long pile is strictly prohibited, since they can wind on the side brush or block the robot's movement. The wipe must be slightly wet, but not draining, so as not to create puddles on the floor.

Some advanced models, such as the Xiaomi Robot Vacuum-Mop 2 Ultra, are equipped with automatic mop lifting. In such devices, it is important to make sure that the lifting mechanism is free of foreign objects. Once the module is installed, the robot will automatically go into the waiting mode for the command to start a mixed cleaning or only washing, as signaled by a voice assistant or light indicator.

• 💧 Remove the dust collector and install the water tank before clicking.
• 💧 Fix the microfiber wipe on the platform's Velcros.
• 💧 Pour clean room temperature water into the tank.
• 💧 Make sure the water supply valve is not blocked (if there is a mechanical switch).

Configure the map and virtual restrictions

A key step in preparing Xiaomi’s robot for wet cleaning is to work with a room map in the Mi Home app. Intelligent algorithms must clearly understand where carpets that cannot be wet and areas where the robot cannot access are located, using the virtual wall and no-go function, which is available after the initial map is completed.

In the map management menu, you need to select the option to create a No-Go Zone or a Virtual Wall. These areas are marked in red, and the robot will avoid them at all costs, even if it means changing the route. For carpets that may be affected by moisture, it is also recommended to create separate zones or use the vacuum only mode, if the model supports automatic recognition of the type of coating.

If your home is intricately designed with multiple sills or dark surfaces, the map may not be built correctly, so dry cleaning is recommended before starting the wet cleaning to clarify the geometry of the room, which will allow the navigation system to better position the forbidden areas relative to real objects.

• 🗺️ Open the map in the application and select "Maps Editing".
• 🗺️ Create red zones over carpets and electronics spaces.
• 🗺️ Divide the room into rooms for selective cleaning.
• 🗺️ Save the changes before starting the task.

Adjustment of water supply level and intensity

One of the most important settings for quality cleaning is water level adjustment. The Xiaomi Home app usually has three or four intensity levels: low, medium, high and automatic. Choosing the right mode directly affects the quality of washing and the time the device runs on a single charge.

For daily maintenance cleaning on hard surfaces such as laminate or tiles, the best choice is medium level. High water supply is designed for highly contaminated areas or kitchen floors, however, it should be used with caution. Low levels save water and allow the robot to work longer, but may not cope with parched stains.

And you have to consider that the speed of the robot also affects the amount of water it's getting. If you set the Careful Cleaning mode, it's going to move slower, which is equivalent to increasing the time it takes to get moisture on the floor. Some models have an electronic valve control feature that only delivers water while it's moving, preventing puddles from forming on the spot.

💡

For the first run of wet cleaning, always choose a minimum water supply level to check the flooring response and avoid potential damage.

Start cleaning through the app and voice assistants

After completing all the preparatory steps, you can go directly to the start of the device. The most flexible settings are available in the Mi Home mobile application. On the main screen of the device, you will see several modes of operation: Quiet, Standard, Turbo and Maximum. For wet cleaning, Standard or Quiet mode is often recommended, as they provide a more even distribution of moisture.

In the cleaning mode selection menu (usually a broom or drop icon), you must select the option "Sweep and wash" or simply "Wash" if the dust collector is already removed. The app will suggest you choose a room or the entire map. If you set virtual restrictions, the robot will automatically take them into account when building the route.

Way to the menu: Mi Home → Device → Cleaning Mode → Wash → Start

An alternative way to run is to use voice assistants such as Yandex.Alice, Google Assistant or Siri (via HomeKit for supported models) Phrases like "Alice, turn on kitchen wet cleaning" work steadily if the devices are connected via a cloud account, but fine-tuning the water level will still require intervention through a mobile app.

• 📱 Open the application and select the script "Wet cleaning".
• 📱 Set the desired level of water absorption and supply.
• 📱 Press the start button or use a voice command.
• 📱 Follow the progress in real time on the smartphone screen.

⚠️ Warning: Do not leave a robot vacuum cleaner with running wet cleaning unattended for a long time, especially in a room with a lot of wires or rapids where it can get stuck.

Resolving typical problems and maintenance

During operation, users may encounter a situation where the robot does not supply water or the application reports an error. Often the cause lies in an air traffic jam inside the pump or clogging of the exit holes. To eliminate the traffic jam, it is recommended to turn the tank upside down (above the sink) for a few seconds or start the water supply mode while the robot is standing at the base to pump the system.

Another common problem is the rapid contamination of the wipe. If the robot has started leaving wiring or collecting dust poorly, it is necessary to stop cleaning and replace or rinse the rag. In models with automatic washing function (bases with a self-cleaning station), it is important to regularly change the water in the dirty tank and flush the filters.

💡

Regular cleaning of sensors and replacement of consumables is the key to a long and efficient operation of the wet cleaning system.

After the cleaning cycle is complete, be sure to remove the water tank, pour out the residues and dry it. Leaving the water in the tank for several days can cause mold, unpleasant smell and corrosion of the internal elements of the pump.
