Owning a Xiaomi Dreame robot vacuum cleaner opens up new horizons in keeping clean, but many users face difficulties in first activating the floorwashing function. Simply adding water to the tank does not start the process automatically, since the smart system requires accurate calibration and software settings. Without the right configuration in the application, the device can ignore wet cleaning or, worse, wet carpets.
To get started successfully, you need to understand the architecture of the interaction between the physical module and the software. Modern models such as the Dreame L10s Ultra or the Dreame D10 Plus have complex logics that depend on the type of attachment installed and the room map. Ignoring the sequence of actions at the first start often leads to sensor errors or incorrect route construction.
In this article, we will take a closer look at the entire preparation process, from the physical installation of the tank to the fine zoning setup in the Dreamehome or Mi Home app, and learn how to avoid typical errors, why a robot may refuse to wash the floor in certain rooms, and how to optimize water consumption for different types of flooring.
Preparation of equipment and installation of the module
The first and most important step is to get the device properly prepared. Before you turn on the wet cleaning, make sure the dust container is removed and a combined water tank is installed in its place. Many users make the mistake of trying to run a sink with a conventional dust container, which software blocks the function.
Care must be taken during the installation of the module so as not to damage the contacts or attachment mechanisms. The electronic contacts at the bottom of the tank should be dry and clean, providing reliable communication with the motherboard of the robot. If the device does not detect the presence of a water tank, try to remove it and install it again before the characteristic click.
⚠️ Warning: Never put a robot vacuum cleaner in wet cleaning mode if there is debris in the dust container, which can lead to dust entering the water supply system and forming hard-to-remove plugs in the pump.
Once the tank is installed, it must be filled with water. For Xiaomi Dreame models, it is recommended to use filtered or distilled water to prevent scale from forming on the internal elements of the system. Using tap water with high hardness will reduce the efficiency of an ultrasonic humidifier or pump over time.
☑️ Preparing the robot for the wash
Setting up the application and choosing the mode of operation
Physical installation is only half the battle, and the main control is through the mobile app, where you switch modes logically. Once you connect the robot to Wi-Fi and add it to your account, you need to go to the settings of your particular device. The interface may vary slightly depending on whether you use the Mi Home app or the specialized Dreamehome app.
In the main robot control menu, find the button or icon that is responsible for the type of cleaning. Often the default mode is "Vacue Only" or "Auto." You need to manually switch the slider to the position "Wet Cleaning" or "Vaccuum and Washing." In some firmware versions, this option is hidden in submenu Cleaning Settings → Cleaning Type.
The choice of water intensity is a special consideration, and modern algorithms allow you to configure three basic levels:
- 💧 Low - suitable for daily maintenance of cleanliness on surfaces that are not afraid of moisture.
- 💧💧 Medium – the best option for mixed coatings and regular cleaning.
- 💧💧💧 High – used to remove old spots on ceramic tiles or linoleum.
Also, be sure to check the settings of carpets in the app menu. The carpet bypass or automatic mop lifting (for top-end models) should be activated if you have textile coatings at home, which will prevent them from getting wet while the robot is running.
💡
If you use a detergent, add only special liquids for robotic vacuum cleaners in strict accordance with the instructions, otherwise the foam can damage the pump.
Mapping and zoning of premises
Effective wet cleaning is impossible without a pre-save map of the room, the robot has to "understand" where the walls, furniture and, critically, the boundaries between the rooms are, and the initial construction of the map usually takes place in dry cleaning mode, after which you can edit it in the application.
To activate the wash in specific areas, use the map split function, which allows you to assign different cleaning modes for different rooms. For example, in the kitchen you can set high water intensity, and in the bedroom you can only dry cleaning or low intensity. Dividing is done through the menu Edit map → Separation.
It's also useful to create virtual walls or no-go zones, especially in places where wet cleaning is highly undesirable.
- 🚫 Near open electrical outlets at a low level.
- 🚫 Around the resting places of pets with textile couches.
- 🚫 In areas with wooden parquet without lacquer coating.
Once the zoning is created, the system will remember the preferences for each room, and in subsequent launches, the robot will automatically apply the specified parameters, which makes it much easier to operate, and saving the map also allows the robot to build more optimal routes without missing sections near the walls.
Why does the robot lose the map?
Comparison of cleaning modes in different models
Xiaomi Dreame’s lineup of devices is extensive, and wet cleaning functionality ranges from basic to advanced.Understanding the differences between models will help you set expectations correctly and use the available features to the maximum.
| Model robot. | Type of mop | Mop lift | Water management |
|---|---|---|---|
| Dreame D9 | Passive (napkin) | No. | Electronic (3 levels) |
| Dreame L10 Pro | vibrating | No. | Automatic. |
| Dreame L20 Ultra | Rotating (double) | Yes (automatically) | Intellectual |
| Xiaomi S10+ | vibrating | No. | Regulated |
Vibration platform models, such as the L10 series, mimic hand movements when washing the floor, which improves the efficiency of removing contaminants. More expensive dual-disc models provide even better cleaning by rotating napkins.
The automatic mop lifting feature is only available in flagship models, allowing the robot to drive onto carpets with a pile of up to 1.5 cm without removing the water tank or stopping cleaning. In budget models, when a carpet is detected, the robot simply passes it or stops.
Solving Typical Problems and Errors
Even with the right setup, there can be situations where wet cleaning doesn't work or doesn't work properly. Most often, the problem is software failure or sensor contamination. If the robot makes an audible signal and stops, check the error code in the application.
One of the common causes is clogging of the water outlets, and over time, microorganisms can develop in the tank or accumulate mineral deposits, and regular flushing of the tank and wiping the contacts of the water pump helps to avoid this.
Also, you should pay attention to the condition of microfiber wipes, if they are too contaminated or, conversely, dry and petrified, the cleaning quality will drop sharply, wipes should be washed after every 2-3 cleanings and periodically replaced with new ones.
⚠️ Warning: If the robot reports a water tank error but the tank is installed, try to wipe the metal contacts on the tank and in the robot niche with a dry cloth. Contact oxidation is a common cause of false positives.
In some cases, a complete map reset and a rescan of the room can help, especially if you've rearranged furniture or changed the layout of the room, and the updated map will allow algorithms to recalculate optimal paths.
Care of the wet cleaning system
The durability of a wet cleaning system depends on the quality of maintenance, regular maintenance not only prolongs the life of the device, but also ensures the hygiene of the floors, neglecting simple rules can lead to unpleasant odor or breakage of the pump.
After each cleaning, it is recommended to remove the tank, drain the remaining water and dry the insides in an open way, stagnant water is the ideal environment for the reproduction of bacteria, which will then be carried throughout the house along with a wet wipe.
Once a month, make a deep cleaning:
- 🧼 Wash the tank with warm water with a mild detergent.
- 🧼 Clean the water level sensors in the tank.
- 🧼 Check the integrity of the sealing rubber bands on the tank cover.
Critical: Never store a robot vacuum cleaner full of water in a tank unless you plan to use it in the coming days, which will prevent the internal elements from corrosion and mold from appearing.
💡
Regular drying of the tank and replacing napkins is the key to the absence of the smell of dampness and the effective operation of the robot for years.
