Running wet cleaning on Xiaomi robot vacuum cleaners often raises questions for new owners who can't find hidden settings or moisten the cloth properly. Modern models like the Xiaomi Vacuum Mop 2 or Roborock S7 have complex work logics that require proper hardware preparation and software tuning through a smartphone.
Unlike conventional sweeping, floor washing requires a special module with a water tank and selecting the appropriate motion algorithm in the application. If you just insert the tank but do not activate the mode in the software, the device can continue dry cleaning or refuse to perform the task. It is important to understand the difference between static rubbing and vibration washing, as this affects the final result.
This article will help you understand all the nuances of the operation of smart assistants from the Chinese giant. We will look not only at the basic actions, but also at the finer settings of the water supply intensity, as well as ways to solve the typical problems that users face when they first get acquainted with the wet cleaning function.
Preparation of equipment for floor washing
The first step is to physically prepare the device and its components, and you need to remove the main dust container and install a combined tank or a separate wet cleaning module that comes with your model, and inside this tank is a water tank that needs to be filled before the MAX mark, using clean tap water or distilled water to avoid scaling at the pump.
Once the tank is installed, you need to attach a microfiber wipe to the holder. Make sure the fabric fits tightly to the surface and does not hang around the edges, which can lead to a robot getting stuck under the furniture. Some advanced models, such as the Xiaomi Robot Vacuum X10+ series, are equipped with an automatic carpet lifting system, so it is important to check that the mounting mechanism is working.
- 🧼 Rinse a new napkin thoroughly before first use to remove the production pile.
- 💧 Use only cold water, as hot water can damage plastic seals and electronics.
- 🔋 Make sure the battery is at least 20%, otherwise the robot will not run the energy-intensive washing mode.
⚠️ Warning: Never add cleaning products, linen conditioners or chlorine-containing liquids to the tank unless expressly permitted by the instructions for your particular model, as aggressive chemistry destroys the rubber pump parts.
The final step is to test the wheels and sensors, wipe them dry, because wet wheels can slide over a smooth tile, which will disrupt the navigation of the device. Once all the components are installed, the robot is ready for software setup.
Setting up scripts in the Mi Home app
The main control is through the Mi Home or Xiaomi Home app, where all the functionality of the smart assistant is hidden. Once you connect the device to the Wi-Fi network, go to your vacuum cleaner card and find the mode control section. This is where you can switch the device from Vacuum Only to Vacuum and Wash mode or select a separate function “Wash only”.
In the cleaning settings (often indicated as a gear or the Cleaning Settings button), you will find a water flow adjuster slider. For laminate or parquet, it is recommended to set a minimum or average level to avoid swelling of the wood. For ceramic tiles or linoleum, you can set the maximum moisture intensity for better removal of stains.
And don't forget about virtual walls and no-go zones, and in the app, you can draw red lines or areas where the robot is not allowed to enter, and this is critical for protecting carpets that can't be wet, or places where there's equipment on low legs, and it takes a couple of minutes to create these areas, but it saves you a lot of problems in the future.
- 📱 Open the app and select your robot vacuum cleaner from the list of devices.
- 🧭 Go to the card settings and use the Virtual Wall tool to limit the wash area.
- 💦 Choose the type of cleaning: “Silent”, “Standard”, “Intensive” or “Maximum” depending on the pollution.
⚠️ Note: When creating forbidden zones, take into account the error of positioning of the robot, leaving a reserve in the 10-15 centimeters from the real obstacle, so that the device does not touch it with a wet cloth.
Starting the process and selecting the motion algorithms
When all the settings are done, you can go to direct start. The main control panel in the app usually has a large start button, but for wet cleaning, you can use specialized scenarios. You can choose to clean the entire apartment, clean the rooms or move along the boards, which is especially effective for removing dust in the corners.
The mapping algorithm is key. If you're launching a wash for the first time, it takes time for the device to scan the room, and at that point, don't move the furniture around or walk actively around the room, so that the laser rangefinder (LiDAR) or gyroscopic navigation builds an accurate model, and after scanning, the robot will start spiraling or zigzagging, systematically covering the area.
☑️ Pre-launch checks
While you're working, you can monitor the progress in real time on your smartphone screen, and the app will show you how much of the area has already been treated, and you can send a robot to clean a particular contaminated area if you need to, and you just click on the right area on the map and select the local cleaning option.
💡
To save time and electricity, set up a cleaning schedule for times when you are not at home, such as working hours, so that the robot does not interfere with you and does not create noise.
Compatibility table for modes and models
Different generations of robot vacuum cleaners support different wet cleaning functions. Below is a table that will help you understand what features are available for popular Xiaomi and Roborock ecosystem devices.
| Model of the device | Type of wet cleaning | Water regulation | Raising the rag |
|---|---|---|---|
| Xiaomi Vacuum Mop Essential | Static (wiping) | Mechanical (slider on the tank) | No. |
| Roborock S7 / S7 MaxV | Vibrational (Sonic Mopping) | Electronic (in annex) | Yeah (automatic) |
| Xiaomi Robot Vacuum X10+ | Rotating (double mop) | Intellectual | Yeah (on the rug ride) |
| Roborock S5 Max | Static with feed control | Electronic (in annex) | No (only programmatically) |
As you can see from the table, older or budget models use passive wiping, where water just drips onto a napkin under the influence of gravity. Newer flagships are equipped with vibration platforms that perform thousands of vibrations per minute, simulating the movement of a person's hand when washing the floor, which greatly improves the efficiency of removing dried spots.

After-cycle maintenance and care
Once the robot has completed its work and returned to base, you can't leave a wet wipe on the holder. The microfibre must be removed, rinsed and dried to prevent the appearance of an unpleasant odor and the reproduction of bacteria. The water tank itself is also recommended to empty if the water is left and wipe it from the inside with a dry cloth.
Check the condition of the filters regularly, although when cleaning wet, the main filter is often not involved (if the module with the main filter is installed). HEPA-With a dry filter, dust can still get inside the case. Once a week, wipe the drop sensors and the docking station, removing possible traces of moisture that may have accidentally splashed.
- 🌬️ Remove the napkin immediately after cleaning and wash it at a temperature not higher than 40 degrees.
- 🧹 Clean the main turbine brush of wound hair that may have got wet and tangled.
- 🔋 Leave the robot on the base to recharge, making sure the contact pads are dry.
Pay special attention to the wheels. If the robot is driving on wet floors, the wheels may be left with dirt and water, which eventually turn into abrasive porridge. Rub the wheels with a wet wipe every two weeks to extend the life of the bearings.
💡
Proper and timely care of consumables (wipes, filters) prolongs the life of the motor and navigation system of the robot, maintaining the quality of cleaning at a high level for years.
Addressing common problems
Sometimes users are faced with a situation where the robot refuses to start a wet cleaning or does it incorrectly. Often the problem lies in a software failure or incorrect installation of the tank. If the device reports an error or simply ignores the command, try rebooting it by holding the on and back buttons to the base (or through the application).
Another common cause is low water levels in the sensor. Even if there is visual water, the sensor may be contaminated or scaled. Rinse the tank with a weak solution of citric acid to remove mineral deposits that block the fluid level sensors.
⚠️ Warning: If the robot leaves too much water on the floor (puddle), immediately stop using and check the integrity of the silicone pads on the tank; the seal or module itself may need to be replaced.
In case the robot gets lost during washing, this may be due to glare on the wet floor that knocks out optical sensors. Try to reduce the brightness of the lighting in the room or, if the model allows, turn off the use of the optical floor sensor in the settings, leaving only the gyroscope and laser.
