How to enable wet cleaning on the robot vacuum cleaner Xiaomi 1C

Modern home automation devices often offer advanced functionality that doesn’t always activate on its own. Xiaomi Robot Vacuum 1C is a prime example of a budget solution where wet cleaning is built into the design but requires manual adjustment before the first run. Many users unpack the box and find that the robot is simply carrying an empty platform without splashing water, causing confusion and searching for the cause of the malfunction.

In fact, to start the floor washing process, you have to do a series of software actions in the application and physically install the water tank. The hardware of the device is fully ready to go, but the software controller blocks the fluid supply until you explicitly specify the type of nozzle installed. This is done for safety reasons, to avoid accidental water spillage when using only the main dust container.

In this guide, we will take a detailed look at the entire activation process, learn how to change the menu mode correctly, what intensity settings exist, and how to avoid common errors that can damage electronics or flooring. Proper preparation is key to the efficient and safe operation of your smart assistant.

Preparation of equipment and installation of the module

The first step is to get the device ready, and unlike the flagship models, where modules can be integrated, version 1C uses a removable system, and you need to make sure that it comes with a special water tank with a microfiber cloth installed in it, and if the robot has a primary dry garbage container, it needs to be removed.

Insert the wet cleaning module into the compartment before the characteristic click. The device automatically recognizes the presence of a new component, but this is only a hardware signal. The electronic system does not yet know how to control the pump and valves, so you will not see visual confirmation on the housing. It is important to check that the microfiber wipe itself is securely attached to the platform Velcros and evenly distributed.

⚠️ Warning: Never turn on wet cleaning if the robot has a dry garbage container installed or if the tank has water but no platform with a cloth installed.

Now that the hardware is ready, you can go to the software part, make sure that the robot vacuum cleaner is connected to the Wi-Fi network and displayed in the list of devices on your smartphone, and without an active connection to the Internet, you can not change the deep settings of the system.

Customization of the cleaning type in the Mi Home application

The main management takes place through the Mi Home ecosystem (or Xiaomi Home). Open the app and go to the management page of your robot. The interface may vary slightly depending on the firmware version and the selected region, but the logic remains the same for all devices in the Vacuum line.

In the main control menu, where you display the room map and battery status, you need to find a button or icon that is responsible for cleaning parameters. Often it is indicated by the gear symbol or located in the upper right corner of the screen. Click on it to reveal the list of available options. Here you will see the item "Cleaning Type" or "Operation Mode".

The default is "Vacura Only" (or "Sweeping"), and you have to change it to "Vaccuum and Water" or "Water Only," depending on your current tasks. Once you select this, the system calibrates the motion algorithm, because when you wash floors, the robot moves differently, often making smoother and shorter passes for better surface treatment.

💡

Without switching mode in the application, the robot will not start to supply water, even if the appropriate tank is physically installed.

Once you have confirmed your choice, a notification may appear on the screen that the mode has changed, from which point the robot is ready to start the wet cleaning cycle. Be sure to check the charge level before starting, since floor washing requires more energy than usual sweeping.

Adjustment of water supply intensity

One of the key features of the Xiaomi 1C is the ability to adjust the volume of water supplied, which is a critical parameter, since different types of flooring require different approaches, laminate or parquet do not tolerate excess moisture, while ceramic tiles can be washed more intensively.

In the same settings menu where you chose the type of cleaning, look for a slider or a water level scale. There are usually three or four gradations available: low, medium, high, and sometimes controlled (smart).

• 🌊 Low levels - ideal for daily cleanliness on sensitive coatings such as laminate or linoleum.
• 💧 Mid-level – a versatile option for mixed floor types and removal of light contaminants that could not be removed during dry cleaning.
• 🌊🌊 High level – designed for highly contaminated tiles or stone, where active soaking of dried spots is required.

Remember, the pump inside the tank is pulsed, and even at a high level, it doesn't pour water in a continuous stream, it doses it in portions, but it's strongly discouraged from experimenting with maximum values on wooden floors to avoid bloating.

💡

Do the test on a discreet area of the floor (such as under the sofa) with the selected water supply level to make sure there is not too much moisture.

Use of virtual walls and zones

The mapping functionality in the Mi Home app allows you to create virtual constraints, which is especially true when wet cleaning. The robot can't distinguish between carpet and hard floor visually, so it can try to drive on a carpet with a wet cloth, which will lead to it getting wet.

To solve this problem, use the Virtual Wall or No-Go feature. In map view mode, click on the appropriate tool and paint over areas where carpets, palaces or electronic areas are located, and the robot will bypass these areas even if they are in the area of its cleaning.

⚠️ Warning: Virtual walls only work if you have an actual map of the room. If the map has been removed or the robot has lost orientation, the restrictions may not work.

Zone Cleanup is also available, so you can select a rectangular area on a map (like a kitchen or an hallway) and start wet cleaning only there, saving battery life and wipe life, allowing you to spot the most contaminated areas.

Comparison of operating modes Xiaomi 1C

Understanding the differences between modes will help you plan your cleaning schedule more efficiently. The 1C offers flexible settings, but each mode has its own technical limitations and engine performance.

Below is a table showing the main differences in robot behavior depending on the selected parameters:

As you can see from the table, Water Only mode turns off the main turbobrush, which is a useful feature if you're afraid that the brush will spread large debris, or if you just want to wipe the floor after you've vacuumed. In combined mode, the control system balances between suction and water supply, which is the most energy-consuming process.

Module care and prevention

It is important to properly care for the damp cleaning system for the longevity of the device. After each use, even if you have not poured all the water, the tank is recommended to be emptied. Stagnant water can cause an unpleasant smell or bacteria to multiply inside the tank.

The microfiber wipe should be washed after 2-3 uses, over time the fabric becomes clogged with fine dust that the vacuum failed to collect, and loses its absorbent properties, and should be washed manually or delicately without using underwear conditioners, which can reduce the effectiveness of the pile.

• 🧼 Washing the tank – once a month, wash the plastic tank itself with warm water to remove plaque.
• 🚫 Chemical prohibition - do not add detergents, foaming solutions or chlorine to the tank. This can damage the pump seals and cause breakage.
• ❄️ Storage – if the robot is not in use for a long time, keep the tank separate from the case in a dry place.

Regular inspection of filters is also required. When wet cleaning, air humidity can increase, and if the HEPA filter gets wet, it will stop letting air through, causing the engine to overheat. Always make sure that the filter is dry before installing.

Addressing common problems

Sometimes users are faced with a situation where everything seems to be set up correctly, but the water does not come in, most often the problem lies in the air traffic jam inside the tank tube system, to eliminate this, you can shake the tank several times strongly (but carefully) or start the robot for a couple of minutes to pump air.

Another reason is contamination of the outlet or pump itself with lime plaque, especially if hard tap water is used, in which case it is recommended to use distilled or boiled water to prolong the life of the pump mechanism.

If nothing works, try resetting the map and re-designing the room. Navigation errors sometimes block specific modes from starting, as the robot cannot correctly calculate the path for wet cleaning.
