How to set up wet cleaning on Xiaomi robot vacuum cleaner

Smart tech owners often face a situation where the device is there, but its full functionality remains undisclosed, especially Xiaomi’s robot vacuum cleaners, which are able to not only collect dust, but also wash floors. However, without the right configuration in the Mi Home or Xiaomi Home app, you risk just wet rags, rather than quality cleaning.

Modern models, such as the Xiaomi Robot Vacuum Mop 2 Pro or the flagship Xiaomi Vacuum Mop 2 Ultra, have complex water supply algorithms. To make them work efficiently, you need to understand the intricacies of the software and physical settings of the module itself. In this article, we will discuss in detail the process of activating and optimizing the washing mode.

Incorrectly configured can lead to puddles or, conversely, dry divorces. Moreover, ignoring certain parameters can reduce the life of the filtration or lead to clogging of the fluid supply system. Let's consider how to avoid typical errors and adjust the device perfectly to your flooring.

Module preparation and tank installation

Before you go to software settings, make sure that the physical preparation of the device is done correctly. Many users forget to remove protective films from new rags or use too hard water, which eventually leads to the formation of scale in the pump. Using distilled or filtered water prolongs the life of the ultrasonic sprayer by 2-3 times.

The process of installing a combined tank requires care. Unlike conventional dust tanks, there are electrical contacts and valves, make sure that the rubber plugs are tightly closed before pouring the liquid, and the tank is installed before the characteristic click.

⚠️ Warning: Never put detergents in a water tank unless your specific model manual explicitly allows it. Aggressive chemistry can eat up seals and damage the pump's electronic components.

• 🧹 Remove all protective stickers from the new microfiber before the first installation.
• 💧 Use only cold water at a temperature not higher than 40 degrees Celsius.
• 🔌 Wash with a dry wipe the contact areas on the tank and in the body of the robot.
• 🔊 Make sure the module emits an audible signal when installed successfully.

Once the device is physically installed, it must automatically detect the presence of the water module, and if that doesn't happen, try re-inserting the tank, swaying it slightly from side to side for better contact.

Connection to the application and selecting a model

The main control is through the mobile application. Users from different regions may need to change the region in the settings of the Mi Account. Most often, for the full operation of robot vacuum cleaners Xiaomi choose the region "China" or "Europe", depending on the version of the device.

Once you add a device to your Wi-Fi network (only 2.4GHz), you need to log into your control card, and that's where all the key settings are hidden. The interface may vary depending on the firmware version, but the logic remains the same across the ecosystem.

It's important to check the firmware version of the robot. Often, wet cleaning functions or their stable operation depend on the software's relevance. Go to the settings (three dots in the corner) and select the update point.

• 📱 Make sure Bluetooth on your smartphone is enabled for quick pairing.
• 📶 Connect your phone to 2.4GHz Wi-Fi, 5GHz networks are not supported.
• 🔄 Check for updates in the General Settings section" →"Verification of updates".

If the robot is in offline status, wet cleaning settings may not be available or saved.

Setting the intensity of water supply

The central control is the water level adjustment, which is usually labeled "Water Volume" or "Water Level" in the app, and there are three main modes available: low, medium and high, depending on the type of flooring and the degree of contamination.

For laminate and parquet, it is critical to use a minimum supply level; excess moisture can lead to swelling of joints and damage to the coating; for ceramic tiles or linoleum, you can use average values, and for severe contaminants in the kitchen, maximum values.

💡

If after cleaning there are traces of wheels or dry stripes on the floor, try to increase the water supply level by one step and reduce the speed of the robot.

Some advanced models, such as the Xiaomi Mijia 1C or Dreame (compatible with the Mi Home), offer automatic adjustment, in which case the robot determines the type of surface and supplies water only to hard coatings, by touring the carpets.

Remember, the intensity of the water supply also depends on the speed of the movement, and if the robot moves quickly, even with a high supply level, the floor may not be wet enough.

Scenario and zoning setting

One of the most useful features of Xiaomi’s ecosystem is the ability to create virtual walls and zones, which allows you to prevent a robot from entering certain rooms or, conversely, send it to wash only the kitchen after lunch.

To create a restriction zone, click on the map edit icon and select Virtual Wall or No-Go tool. Draw a rectangle in an area where the robot is not allowed to enter, especially for areas with carpets that are not planned to be wet, or near animal bowls.

There's also a "Spot Cleaning" or "Room Cleaning" feature, so you can select a specific room on the map and start wet cleaning only there, which saves battery life and water tank life.

⚠️ Warning: Virtual walls and zones are stored in the robot's memory. If you rearrange furniture, remember to update the map, otherwise the robot may begin to build routes through new obstacles.

For complex scenarios, you can use in-app automation, such as setting up a wet kitchen cleaning routine every day at 14:00 when everyone left home.

Safety and maintenance

Regular maintenance is the key to a long life for your assistant, and after each wet cleaning, it is recommended to remove the cloth and wash it so that dirt does not rub into the floor the next time you run it, and the water tank itself also requires periodic washing.

HEPA and pre-treatment filters must be kept dry, if water gets on them, they can quickly fail or cause an unpleasant odor, and always remove the filter before pouring water into the tank, unless the design provides for complete insulation.

Keeping a water module inside the robot, unless you plan to clean it in the coming days, is not recommended. Stagnant water can bloom, especially in a warm room, it is better to drain the residues and dry the tank.

• 🌬️ After cleaning, remove the tank and let the insides of the robot dry for 30 minutes.
• 🧼 Once a month, wipe the sensors on the body with a dry cotton swab.
• 🔋 Do not leave the robot on a charge with a full tank of water for a long time (more 2-3 days).

Compliance with these simple rules will help to avoid mold inside the system and maintain the efficiency of absorption.

Solving Wet Cleaning Problems

Sometimes users find that the robot stops supplying water or does it unevenly, often because of a traffic jam in the pump, which can be removed by manually running the water supply mode through the app (if the model supports), or simply turning on and off the wash mode several times.

Another common problem is that the robot spits water or leaves puddles, which may indicate that the valve is malfunctioning or that it uses too soft water to penetrate the membrane, so it's better to keep the supply level to a minimum.

💡

If the robot leaves dry stripes at maximum water level, most likely, the cloth is dried or pressed too hard against the floor - check the pressing mechanism and the moisture of the napkin.

If you have an error in the application (flashing indicator), refer to the error code in the instructions. Often the problem is solved by simply restarting the device by holding the off button for a long time.
