The introduction of robot vacuum cleaners has dramatically changed the way we keep things clean, but many Xiaomi device owners still use them in dry cleaning mode, a significant omission because wet cleaning allows you to remove the dust and light dirt that the brush just disperses around the apartment. Understanding how to properly activate this mode is key to fully operating your smart assistant.
The start-up process may not seem obvious to a beginner, since it requires not only pressing a button on the case, but also pre-prepared equipment and setting up in the mobile application. Wet cleaning is not just about having water in the tank, it is a complex pump algorithm that needs to be activated programmatically. In this article, we will discuss all the steps, from installing the module to fine-tuning the water intensity.
Before you go to software settings, make sure your device is physically ready to work with liquids. The Vacuum Mop series models are structurally different from conventional vacuum cleaners by having a special compartment for the combined tank. Ignoring physical requirements can lead to breakdown of electronics, so we start by checking the configuration and installation of the module correctly.
Compatibility check and equipment preparation
The first step should always be to identify your model, as not all Xiaomi robots support floor washing. Basic versions such as Xiaomi Vacuum 1S or Mijia 1C often do not have the ability to install a water tank without buying additional, not always official modules.
Visually, you can tell the right tank by having an electronic contact or a special hole to install a rag nozzle. Inside the tank is an electronic pump that delivers water to the napkin in doses. If you try to install a regular dust container in wash mode, the robot simply cannot execute the command, because the sensors will not detect the presence of the necessary module.
It's also critical to check the condition of the filters, and before you start operating in 2-in-1 mode, you'll make sure that you're in a state of the filter. HEPA-The filter is dry and clean. If you get water on the filter, it will swell up and the suction engine will fail. Some users use safety nets, but it's best to just be careful when you install the tank.
☑️ Pre-launch checks
Once the tank is physically installed, the robot must issue a distinctive audible signal or a voice message confirming the recognition of the new module. If this does not happen, try to remove and re-insert the container before clicking. The lack of response of the device indicates that the contacts are malfunctioning or the installed part is incompatible.
Set up the Mi Home app to manage the wash
The main control of all the functions of the Xiaomi smart home is through the Mi Home application. To activate wet cleaning, you need to open the card of your device in the program interface. This is where all the necessary switches are hidden that are not available through the buttons on the vacuum cleaner case.
In the top control menu, find an icon that indicates the mode of operation, usually an image of a water droplet or a Water Mode inscription. Pressing this element opens the slider of adjusting the fluid intensity, here you can choose the level from the minimum (for daily cleanliness) to the maximum (for removing dried spots).
It is important to note that settings may vary depending on the region chosen in the app. If you can't see the water management menu, try changing your account region to China or Europe, as the servers' functionality sometimes differs.
💡
To save battery and water, use the “Intelligent” mode, where the robot itself determines the degree of floor pollution and regulates the supply of moisture.
Don't forget to update the robot's app and firmware. Manufacturers often release patches that improve pump algorithms and fix server communication errors. You can check the version in the device settings by going to Settings → About Device → Check for updates.
Installation of a tank and microfibre wipe
Technically, the correct installation of the tank is 90% of the success of the entire operation. Unlike a dry container, the wet cleaning module has a large mass due to the water, so it must sit very tightly in the nest. Make sure you remove the dry dust collector before installing the water tank, since the two modules cannot work simultaneously.
Pay special attention to the microfiber wipe attachment, which must be pulled over the plastic platform of the tank and fixed with Velcro or clamps on all sides, sagging fabric can wind on the side brush or get stuck under the wheels, which will cause the robot to stop and an error in the application.
Before installation, the napkin is recommended to be wet and pressed well by hand. Although the robot moisturizes the fabric during operation, the starting moisture supply helps the pump start pumping water through the system faster. A dry napkin in the first minutes of cleaning can simply smear the dust instead of collecting it.
⚠️ Warning: Never use flavorings, chlorine-containing products or hot water in the robot tank.This will corrosion the pump's internal tubes and destroy sealing gums, which is not a warranty case.
Once the tank is installed, flip the robot over and check if the rag platform is blocking the drop sensors or charging contacts. Xiaomi tanks typically have cutouts for sensors, but using non-original accessories can cause navigation problems.
Choosing the mode of cleaning and intensity of water supply
In the Mi Home app, the user has three main water intensity levels: low, medium and high. The choice depends on the type of flooring and the degree of contamination. For laminate or parquet that are afraid of excess moisture, it is recommended to use a minimum level.
High intensity mode is designed for ceramic tiles or linoleum in the kitchen, where often there are greasy spots or spilled liquids. In this mode, the pump runs almost continuously, providing abundant wetting of the wipe, but it is worth remembering that this significantly reduces the battery life of the device.
There's also a point cleaning or local wash mode where the robot concentrates on one area, which is useful if you accidentally spill something, and you can activate it through an app or double-press a button on the case (depending on the model), pre-setting the robot in the right place.
Intelligent algorithms such as the Xiaomi Vacuum Mop 2 Pro+ can automatically reduce the water supply when you return to the base to recharge, so you don’t have to wet the dock, but you don’t have to rely on automation alone, you have to manually monitor the first cleaning process.
Creation of virtual walls and forbidden zones
One of the most important features of wet cleaning is the ability to restrict the robot's access to certain areas of the map. Carpets, especially with long pile, are strongly discouraged from wetting. The Mi Home app has a Virtual Wall or No-Go tool.
To create this zone, go to map editing mode, select the Square or Line tool, and circle the carpet area. Once you save the settings, the robot will ignore this area when the wash mode is turned on, even if it physically lands on it, it will not activate the pump.
For models with automatic mop lifting (such as the Xiaomi Robot Vacuum X10+ series), creating no-go zones for mats is less important, since they recognize the pile and lift the module themselves. However, for standard Vacuum Mop models, manually adjusting maps is the only way to protect textiles from getting wet.
| Type of coating | Recommended treatment | Water intensity | Features |
|---|---|---|---|
| laminate | Quiet/Standard | Low. | Avoid puddles, rapid drying |
| Tile. | Standard/Turbo | Medium/High | Good at washing stitches |
| linoleum | Standard | Medium | Resistant to moisture, but sliding |
| Natural stone | Quiet | Minimum | Requires special equipment (not in the tank) |
Using virtual walls is also important for protecting places where wires, clothing or animal water bowls are lying. A wet-tank robot has an increased turning radius and weight, so the risk of touching and turning objects is higher than with dry cleaning.
Tanking maintenance and care after cleaning
Proper maintenance of the equipment after the cleaning cycle is completed prolongs the life of the device. Once back at base, be sure to remove the combined tank. The remaining water in the tank can bloom or evaporate, leaving scaling on the inner walls and pump.
Remove the microfiber wipe and wash it. Using a dirty cloth will result in the robot simply smearing dirt across the floor, creating smudges. Use regular powder for washing, but avoid air conditioners that can reduce the absorbency of the fabric.
Wash the plastic tank with clean water, pay special attention to the water outlet and the contacts at the bottom of the tank. If the contacts are oxidizing or dirt, the robot may stop seeing the module. Rub them with a dry soft cloth.
What to do if the pump does not pump water?
Keeping the water tank inside the robot off is not recommended, and it puts extra strain on the structure and increases the risk of accidental leakage if the device moves from its place, so it's better to keep the tank separate, in a dry place.
Frequent problems and methods of their solution
Despite the reliability of Xiaomi's equipment, users may face typical problems, one of the most common is that the robot reports that there is no tank, although it is installed. In this case, wipe the contacts on the tank and in the body of the robot with an alcohol napkin. Often oxidation interferes with signal transmission.
Another common problem is uneven wetting of the napkin, which may indicate a traffic jam in the system, try pressing the pear of the tank several times (if you have one in your model), or slightly shake the tank to kick the air out of the tubes, and also check if the outlet is clogged with pile.
⚠️ Warning: If the robot makes a loud crackle when trying to ride onto a wet-tank carpet, immediately pick it up.
If the robot gets lost or builds a faulty map when cleaning wet, wipe the drop sensors and lidar (the turret at the top). Drops of water or spray on the sensors distort the data, and the navigation system fails. Regular dry wipe of sensors before starting is a good habit.
💡
The main secret of successful wet cleaning is regular water change and washing of a wipe, not just periodic switching on of the regime.
If none of these methods work, reset your card and try to reconfigure your device. Sometimes, the card's software errors prevent you from running complex cleaning scenarios correctly. In extreme cases, contact your pump diagnostics service center.
