Robot vacuum cleaner Xiaomi: how to use with wet cleaning and video instructions

Xiaomi’s modern robot vacuum cleaners have long since ceased to be just toys, becoming full-fledged assistants capable of maintaining cleanliness with little or no human intervention. Many users, when purchasing S, M or G series devices, often face the question of properly operating the wet cleaning function, since basic instructions do not always contain exhaustive details. In this article, we will discuss the process of preparing, setting up and launching wet cleaning, based on official manuals and practical experience of owners.

To begin with, it is important to understand that wet cleaning in the Xiaomi ecosystem is implemented differently depending on the model. In some devices it is a simple hinged platform with a flowing water supply, in others it is a complex system with vibration and automatic washing of the rag on the base. The key difference is the ability to adjust the water supply through the Mi Home application, which allows you to adapt the cleaning to the type of flooring. Before the first launch, we strongly advise you to carefully study the equipment so that you do not damage the sensitive electronics with improper installation of modules.

The video instructions we'll discuss in this article help visualize the process of assembling a water tank and mounting a cloth holder. However, a text description with an emphasis on important nuances of software settings will avoid common mistakes such as wetting carpets or not moisturizing the floor. Let's take a step-by-step look at how to turn your gadget into an effective floor washer.

Preparation of the device and installation of a water tank

The first step before starting the wet cleaning mode is to physically prepare the robot. You need to remove the main dust container if your model is combined with a water tank, or install a separate water module in a special compartment. In the Xiaomi Robot Vacuum S10 or Roborock S7 series, the tank design may differ, so it is important to make sure that the rubber plugs are tightly closed before filling.

Pour water should only be cold, preferably filtered or distilled to prevent scaling on the inner walls of the pump and nozzles. Using hot water or aggressive detergents can cause the membrane pump to fail, which is not a warranty case. After filling the tank, you must carefully wipe its outer surface with dry rags to prevent droplets from hitting the contact groups.

Installation of the tank in the body of the robot should be accompanied by a characteristic click of the locking mechanism. If you hear the sound of gurgling immediately after installation, then the leakage is broken and the system needs to be rechecked. For models with a combined tank (2-in-1), it is important not to confuse the compartments and make sure that the dry cleaning filter is removed or replaced with a special filter with moisture protection, if the instructions for a particular modification require.

⚠️ Warning: Never turn on wet cleaning if the robot has a regular paper dust bag or HEPA-This will cause the filter to swell instantly and possibly short circuit.

Once the module is physically installed, the robot usually emits an audible signal or a voice message indicating readiness for operation, at which point you can move to the software part of the setup, which plays a crucial role as the final result.

Setup the Mi Home app and device binding

To control all the functions of the smart vacuum cleaner, a single Mi Home app (or Xiaomi Home) is used. If you haven’t already added the device to the network, make sure that the smartphone is connected to a 2.4 GHz Wi-Fi network, since most robot models do not support the 5 GHz standard. The addition process is usually automatic: open the application and it will suggest setting up the device found nearby.

Inside the app, you need to go to your device card and find the cleaning settings section, and that's where the key water intensity settings are located. There are usually three or four levels available: low, medium, high and smart. The level selection depends on the type of contamination and the floor material: the laminate is better to choose the minimum supply, and the average values for the tile or linoleum can be set.

  • 📱 Low level: suitable for light ground refreshment and sensitive coatings such as parquet or chamfered laminate.
  • 💧 Medium level: the best option for daily cleaning of mixed types of coatings in the apartment.
  • 🌊 High level: Recommended for highly contaminated areas, kitchen or bathroom tiles (if the model allows for it).
  • 🧠 Smart mode: the algorithm independently selects the intensity based on the analysis of the map and the type of room.

You can also activate the “Wash only carpets” function in the settings (if there is support for carpet recognition) or prohibit entry into certain areas. For models with Mop Lift function, be sure to turn on this option so that the robot automatically lifts the module when entering the carpet, avoiding getting wet.

Video Instructions: Step-by-step start of wet cleaning

Because the textual description of the interface may vary depending on the firmware version, visual demonstration of actions is the most effective way to learn. The video guide below shows the full cycle of preparing the Xiaomi Vacuum-Mop 2 Pro robot for work, including installing a magnetic rag holder.

Notice the sequence of actions: first, the map is calibrated, then the robot determines the location of the docking station. Only then, on command from a smartphone or voice request, the wet cleaning process begins. In the video, you can clearly see the robot making movements in the form of the letter "Y" or "Z", which provides better cleaning of spots compared to chaotic movement.

Launch sequence through the application:


1. Open Mi Home -> Select the device




Press the "Vacuum" button




3. Select the "Wet Cleaning" mode (Mop)




4.Push "Start"

It's important to monitor the behavior of the robot in the first minutes of operation, and if you notice that it leaves too much moisture or, on the contrary, drives on the dry floor, you need to immediately stop cleaning and adjust the water level settings in the application. Some models allow you to change the intensity of the water supply directly during operation, without stopping the device.

Working with virtual walls and zoning

One of the most useful features in Xiaomi’s ecosystem is the ability to create virtual restrictions, which is critical for wet cleaning, as it protects carpets, walkways and electronic areas from water ingress, and in the Mi Home app, these features are located under “Maps settings” or “Virtual walls.”

You can draw rectangular No-Go Zones on top of carpets, and the robot will ignore those areas by going around the perimeter, and there's also a wash-only mode that forces the device to ignore dusty areas unless they're marked as requiring attention, and focus solely on washing the floors in the specified rooms.

Type of restrictionFunctionWhen to use
Virtual wallTotal ban on entryFor carpets, wires, places with toys
No cleaning areaIgnoring the siteFor fragile items on the floor
Extensive cleaning areaDouble aisle and more waterFor the kitchen or the hallway
Room separationZone divisionSelective cleaning of specific rooms

Using zoning can save a lot of battery life and rag life. You can send a robot vacuum cleaner to only wash the kitchen after lunch without having to drive around the whole apartment. This is especially true for models with a small volume of water tank, which may not be enough on (the whole apartment) with high water intensity.

⚠️ Warning: When creating virtual walls, make sure they don't block the way to the dock.If the robot can't return to the base for recharging or (in top models) for refueling with water, cleaning will be interrupted and the device may lose the map.

Maintenance and care of the wet cleaning module

Proper maintenance of the wet cleaning system prolongs the life of the device and ensures that there are no unpleasant odors. After each use, you need to remove the water tank, drain the remaining water and wipe the inner surface with a soft cloth. Stagnant water is the ideal environment for bacteria to multiply and mold to appear.

Microfiber rags should be washed after 2-3 uses. Machine washing is allowed at a temperature of no more than 40 degrees, the use of air conditioners for laundry is prohibited, as they reduce the absorbency of the material. For models with automatic washing of the base (for example, Xiaomi Robot Vacuum X10+), it is necessary to regularly clean the base itself, removing and washing filters and trays for dirty water.

  • 🧼 Cleaning the tank: once a week wash the tank with warm water with a soft detergent.
  • 🦶 Wheels and sensors: wipe the wheels and water level sensors to avoid the “Tank is empty” or “Tank is full” errors».
  • 🔋 Storage: If the robot is not in use for a long time, keep the tank separate from the case in dry form.

Regularly check the condition of the brush-roller in the wet cleaning module (if any in your model), it can be wound hair and wool, which reduces the efficiency of rotation and can lead to engine overload. Cleaning takes a couple of minutes, but significantly improves the result.

Common Errors and How to Resolve Them

Even when properly operated, users can encounter a variety of errors. Often, a robot reports low water levels even though the tank is full. This may be due to clogging of the outlet or an air plug in the supply system. Try pressing the water supply valve several times or blowing the hole.

Another common problem is that the robot gets lost during wet cleaning, which happens when floor sensors (which detect the difference in altitudes to avoid falling off stairs) are closed with a damp cloth or dirt. Regularly wiping the sensors with a dry wipe solves this problem, and also make sure the room is light enough, as optical navigation sensors do not work well in the dark.

What to do if a robot smears dirt?
If the robot is washing the dirt instead, it means that the cloth is too wet or has not changed for a long time. Replace the water with clean, squeeze well or replace the cloth. In the application, reduce the water supply. For old contaminants, pre-vacuate the floor in dry mode.

If you notice that the robot leaves stripes or doesn't completely clean up the dust, it may be time to replace the cloth. The microfiber loses its abrasive and absorbent properties over time. The original consumables provide better compatibility and efficiency for intelligent cleaning algorithms.

⚠️ Warning: Do not use a robot to clean spilled liquids (milk, soup, juice) The water tank design is not designed to pump fluids from the floor, this will lead to dirt entering the pump and irreversible damage to electronics.

Frequently Asked Questions (FAQ)

Can I add detergent to the water tank of the Xiaomi robot?
Xiaomi officially recommends using only clean water. Adding aggressive chemicals, chlorine or foaming agents can damage rubber seals, pumps and plastic elements of the tank. There are special neutral concentrates for robotic washers, but their use is at your risk and can void the warranty.
How often should I change my rag for wet cleaning?
The life of a microfiber cloth depends on the intensity of use and type of flooring. On average, when cleaning an apartment with an area of 50-60 square meters, it is recommended to change the cloth every 3-6 months. If you notice that it has ceased to collect dust efficiently or there are irremovable stains, you should replace it earlier.
Why can't the robot see the water tank?
Most often, the problem is oxidized contacts on the body of the robot or tank. Wipe the contacts with dry soft cloth. Also make sure that the tank is installed before clicking and the magnetic sensor (if it is in the model) is not offset. In rare cases, you need to flash the device.
Can I start a wet cleaning while I’m not home?
Yes, this is one of the main functions of a smart home: you can set up a cleaning schedule or run it remotely through an app, make sure that before you leave, the tank is filled and there are no small items, wires or clothes on the floor that can wind on the brushes.
