How to set up wet cleaning on Xiaomi robot vacuum cleaner

Owners of modern smart devices often underestimate the possibilities of automation, limiting themselves to dry cleaning, although the function of wet cleaning can dramatically change the quality of maintaining order in the house. Properly configuring this mode requires a careful approach to the choice of accessories, since the use of improper rags or improper installation of the tank can lead to divorces or even damage to the electronics of the device.

In this article, we will take a detailed look at all the preparation steps, settings through the Mi Home app and the intricacies of operation that will allow you to get a perfectly clean floor without unnecessary effort.

Before you move on to software settings, you need to physically prepare the device for operation, making sure that all components are installed correctly and ready for contact with water.

Preparation of equipment and installation of a water tank

The first step is to check the configuration, as not all Xiaomi robot vacuum cleaners have a built-in water tank as standard, and sometimes you need to purchase it separately.You will need a special combined tank that combines a dust container and a liquid compartment, or a separate module with electronic water control if it is a flagship series.

Be sure to use only distilled water to prevent scaling from forming on the pump and white marks on the dark floor surfaces after drying. Before installing the tank, make sure the rubber plugs are tightly closed and the container itself is fixed to a characteristic click to prevent leaks during movement.

It is important to properly fix the tissue napkin on the holder, using Velcros or magnetic fixers provided by the design of a particular device model.

Make sure the fabric doesn’t hang too low and touch the wheels, which can cause Cliff sensors to make mistakes, perceiving the hanging fabric as a floor break.

⚠️ Warning: Never pour detergents, chlorine or aggressive chemicals into the water tank, as this will lead to the destruction of rubber seals and the failure of the pump, which is not a guarantee case.

• 💧 Use only soft distilled or filtered water to extend the life of the pump.
• 🧹 Fix the microfibre wipe evenly, without creases, to avoid uneven washing.
• 🔌 Make sure the electrical contacts on the tank and in the robot body are dry before installation.
• 🚫 Do not turn on the wet cleaning mode if there is debris in the dust collector, which can turn into mud porridge.

After the physical installation of the components, you need to make sure that the device sees the new module and is ready for software configuration via the smartphone.

Setting up water supply modes in the Mi Home application

To control the humidification settings, you need to open the Mi Home app, select your robot vacuum cleaner, and go to the cleaning mode settings, which usually displays a drop icon or a separate cleaning type switch. Depending on the device model, the interface can offer a choice of three or four water intensity levels: low, medium, high, and intelligent mode.

Low levels are suitable for daily cleanliness on surfaces that do not require heavy friction, such as laminate or lacquer flooring. Middle and high levels are for tile, porcelain or linoleum with pronounced relief, where more active exposure to moisture is required to remove contaminants.

Some advanced models, such as the Roborock S Max series or Xiaomi Vacuum Mop 2 Pro, feature smart coating type determination, allowing you to automatically adjust the water supply.

When choosing an in-app mode, focus on the degree of floor contamination and the type of material to avoid excessive moisture, which can be harmful to wood coatings.

• 📉 Low level: for delicate surfaces and daily light cleaning.
• 📈 High level: for kitchen, hallway and severe contamination on the tile.
• 🧠 Intelligent mode: automatic adjustment based on map data and type of coverage.

Choosing the right water intensity is a balance between effectively removing dirt and the safety of your flooring.

Working with virtual walls and forbidden areas

One of the critical features of wet cleaning is creating virtual restrictions that prevent the robot from entering carpets, palaces or areas with electronics and paper products. In the Mi Home or Xiaomi Home app, you need to switch to map editing mode, where the No-Go Zones and Virtual Walls drawing tools are available.

The no-go zone is a square or rectangle that the robot will not go inside under any circumstances, which is ideal for protecting carpets from getting wet. The virtual wall works as an invisible barrier through which the device cannot cross the line, which is convenient for restricting access to certain rooms or areas with wires.

When creating constraints, it is important to leave a small margin, as the inertia of movement and positioning accuracy can vary depending on the battery charge and condition of the wheels.

It is recommended to create separate maps or scenarios for different types of cleaning if there are many carpets in the house so as not to reconfigure the zones manually each time.

Using these tools allows you to fully automate the process without fear that a smart assistant will wet expensive carpets or spill water from an open bowl of a pet.

Planning and schedule of wet cleaning

Automation is a key benefit of a smart home, allowing you to start cleaning in the absence of the owners or at night when the noise level does not matter. In the application schedule section, you can create a new timer by selecting the days of the week, start time and, most importantly, the type of cleaning - in this case, you need to activate the option "Wet cleaning" or "Washing the floors".

To work efficiently, it is recommended to set the start time so that the floor will dry completely when you arrive, especially in winter or in areas with poor ventilation. It is also worth considering the battery life: if the area is large and the charge is not full, the robot can leave for base before the plan is completed.

Some models support the Quiet Clean feature, which automatically reduces suction power and night-time movement speed, which can be useful if the robot is working while you sleep.

Regular use of the schedule helps to maintain a stable cleanliness without the need for constant manual intervention and control.

⚠️ Note: Do not set a schedule for when no one is home if you have pets that may be scared of the device or try to jump on it while driving.

Wet cleaning system care and maintenance

Regular maintenance is necessary to ensure that the water supply system works correctly and the quality of cleaning does not decrease over time. After each use of wet cleaning, it is recommended to remove the tank, drain the remaining water and wipe the inner surface with a soft cloth to prevent the development of bacteria and the appearance of unpleasant odor.

Cloth wipe should be washed after 2-3 uses, using neutral detergents, and dried in a straightened form, so that it does not lose its shape and absorbent properties. Periodically, every 1-2 months, you should check the state of the pump and the outlet, carefully cleaning them with a cotton swab if there are signs of clogging or decrease in pressure.

💡

For deep cleaning of the water supply system, you can start a water supply cycle without a napkin over the sink to wash the channels with clean water.

If you notice that the robot has started leaving dry stripes or, conversely, puddles of water, this is a signal to check the water level in the tank or the condition of the napkin itself.

Timely replacement of consumables such as wipes and filters ensures that your robot vacuum cleaner will operate at maximum efficiency throughout its life.

• 🧼 Wash wipes at a temperature not higher than 40 degrees without using air conditioners.
• 💧 Dump the remaining water from the tank after each cleaning to avoid stagnation.
• 🔍 Once a month, check the pump output holes for the presence of lime plaque.
• 🔄 Change your napkin for a new one every day. 3-6 months depending on the intensity of use.

Solving typical problems and malfunctions

During operation, users may face a number of typical problems, such as uneven wetting, sensor errors or failure of the device to start the wet cleaning mode. Often the reason lies in the suffocation of the system: if the tank was not used for a long time, the tubes could form an air bubble that interferes with the flow of water.

To address this problem, you can try several times pressing the water supply button in the application or gently shake the tank (pre-closing the valves) to expel the air. If the robot reports a tank installation error, check the purity of the contacts and make sure that the tank is inserted to the stop and the latch is not damaged.

💡

Most wet cleaning problems are solved by simply cleaning the contacts, replacing the water with distilled or restarting the device.

In case the software methods do not help, you may need to reset the card settings or update the device firmware through the application to the latest version.

If the problem persists after all manipulations, you should contact the service center, as it is possible damage to the pump or control board.

Compliance with these simple rules and guidelines will allow you to maximize the potential of your smart assistant and enjoy cleanliness in the house without unnecessary effort.
