How to make a wet cleaning robot vacuum cleaner Xiaomi Mi Robot Vacuum

Many owners of Xiaomi smart appliances are wondering how to effectively organize the process of floor washing using the functionality of their device. Modern models such as Xiaomi Mi Robot Vacuum Mop Essential or more advanced versions of the Roborock series are equipped with modules for wet cleaning, which greatly simplifies everyday life. However, to get a truly clean floor without divorces, you need to properly prepare the equipment and adjust the parameters in the application.

Unlike dry cleaning, water management requires certain safety and sequence rules. Incorrect tank installation or use of inappropriate fabric can lead to leaks and even damage to robot electronics. In this guide, we will detail all the steps of preparing, setting up and conducting wet cleaning, so that your Xiaomi Vacuum serves long and efficiently.

Before starting use, it is important to understand that not all models support active staining, some only wipe the surface. The key difference between the models with the Mop function is the presence of an electronic tank with water control, which allows you to adapt the humidification intensity to the type of flooring, whether it is tile, laminate or linoleum.

Preparation of the robot and installation of a module for washing

The first step is to physically prepare the device for operation. You need to remove the standard dry garbage container, if it is installed, and replace it with a combined 2-in-1 tank or a special water module. Make sure that the contact areas on the robot body and tank are clean and dry to avoid sensor errors.

Next, you need to properly attach the tissue napkin to the holder, it must fit tightly to the sole of the tank and not hang around the edges, otherwise it can make it difficult to move the wheels.

• 🧼 Wash the tissue wipe thoroughly before first use to remove the manufacturing dust.
• 💧 Use only clean tap water or filtered water, avoiding adding aggressive chemicals.
• 🔋 Make sure that the battery is at least 20% before starting a long cleaning cycle.

Importantly, some models require activation of the wash mode in the settings before water starts to flow to the napkin.If you are using the Xiaomi Mi Robot Vacuum Mop P model, check that the water supply valve is not locked and is working correctly.

Water tank filling and liquid selection

The process of filling the tank with water seems simple, but it has its own nuances: Open the valve on the top of the tank and pour water to the MAX mark. Do not overflow the liquid under any circumstances, as this can lead to moisture entering the body when installing the tank.

It is strictly forbidden to use chlorine-containing products, underwear conditioners or foam solutions, such substances can destroy rubber seals, clog the pump or cause foam formation that will disrupt the operation of fluid level sensors.

⚠️ Warning: Never immerse the tank electronic module completely in the wash water. wipe it with only a wet cloth to avoid short circuits of internal contacts.

After filling, close the lid tightly and make sure the rubber plug is in place with a characteristic click. Shake the tank (pre-close the exit hole with your finger) to check the leakage. If water does not drip through the napkin at rest, the system is ready to go.

💡

For best results, use distilled water – this will prevent the formation of lime plaque on the heating elements (if any) and inside the water supply tubes.

Setting up parameters in the Mi Home app

Physical training is complete, you now need to configure the software part. Open the Mi Home app on your smartphone and go to control your device. In the upper right corner or in the settings menu (three dots), find the item responsible for the cleaning options.

You can choose the intensity of the water supply here, and you can usually choose between three or four levels: low, medium, high, and sometimes smart, and you can set the average for the laminate floor to keep clean on a daily basis, whereas you can set the average for the tile kitchen.

You can also set up no-go zones in the app, which is a critical feature for wet cleaning, and you can draw virtual walls around carpets, electrical appliances, or places with wooden floors that are afraid of moisture, and the robot will ignore those areas when it's washing.

• 📱 Set a cleaning schedule for when you are not at home to avoid slippery floors when you return.
• 🗺️ Save a few cards with different settings if you have a multi-storey house.
• 🔊 Turn off the speaker if the robot is working while you are watching TV or sleeping.

Remember to check firmware updates periodically in Settings → About Update. Xiaomi engineers are constantly improving the route and water distribution algorithms, so the current version of the software guarantees better performance.

Starting cleaning and monitoring the process

Once you've set up the robot, you can start it. You can press the Start button in the app or the physical button on the device body. You can start building the map (if it's the first run) or you can start cleaning it right away on a known route. In wet cleaning mode, the movements can be smoother and more reciprocal.

When you're running, the app will display status: "Clean up," "Charge," "Error." If the robot is stuck or the tank is empty, you'll get a push notification. In wash mode, the robot can work longer, as it takes longer to go through the area for a good wipe.

Make sure the robot doesn't get stuck on dark carpets that some models may perceive as a cliff. If this happens, seal the drop sensors on the bottom panel with black tape or use physical stoppers.

Post-cycle maintenance

When the robot completes cleaning and returns to base, don't leave the wet tank inside the device for long. Moisture can be conserved, causing an unpleasant odor or mold. Remove the module immediately and empty the water.

Remove the tissue tissue and rinse it thoroughly. If there is hair or wool on the fabric, remove it mechanically. It is better to dry the napkin in a straightened form, away from direct sunlight, so that it does not lose its absorbent properties.

Once a month, it is recommended to carry out preventive cleaning of the tank itself, you can use a weak solution of citric acid to remove possible lime plaque from the inside, after this treatment, be sure to rinse the tank several times with clean water.

⚠️ Warning: If you plan not to use the robot for a long time (more than 3 days), keep the water tank separate from the housing, completely dry and with the lid open.

Solving problems with wet cleaning

Sometimes users are faced with a situation where the floor remains dry or, conversely, too wet. If there is no water, check if the outlet is salty. Often microscopic salt crystals block the feed channel. Wipe the outlet with a wet wipe or use a toothpick for a careful cleaning.

If the robot leaves puddles, it may be that the water supply level is too high for this type of coating, and it's also worth checking the density of the napkin: if it dangles, the contact with the floor will be uneven, and in some cases, replacing the napkin with a new one helps, as the pile wears out over time.

In case the robot starts to rush around the room in a wet cleaning, the collision sensors or the laser rangefinder (LDS) upstairs may have become contaminated, wipe them with soft dry cloth, and the cleanliness of the sensors is the key to proper navigation.
