Many smart homeowners are faced with a misunderstanding of the basic functions of the device immediately after unpacking. Xiaomi Vacuum Cleaner 1C is a prime example of a robot that is often perceived as a device solely for dry cleaning. This is a common misconception, because the device supports the function of wet floor cleaning, but it is implemented through a removable module that does not come as standard in all regions. It is the lack of a preinstalled water tank that often confuses users, making them think that their device is malfunctioning or limited in functionality.
The process of activating the floor washing capability requires not just a fill-up of the liquid, but the correct physical installation of a special container. The default standard dust collector has no water compartments and no moisture supply mechanisms for the rag. Therefore, the standard procedure of "open the lid and pour water" here will not work and can lead to electronic breakdown. You will need to purchase a compatible combined tank or a separate module for wet cleaning, developed specifically for the STYTJ01ZHM series.
In this guide, we will discuss in detail how to properly prepare the system, install the module and adjust the parameters of the water supply through the application. Ignoring the rules of operation can lead to moisture entering the turbine, which is a difficult case for warranty maintenance. The security of the device depends on the sequence of your actions when replacing consumables. Below are step-by-step instructions that will help avoid typical errors and prolong the life of your assistant.
Preparation for installation of water module
Before any manipulation of the robot's internal compartments begins, it is necessary to ensure that it is completely immobile and turn off the power. Although the Xiaomi Vacuum 1C is equipped with sensors, accidental start of the engine during a tank replacement can lead to mechanical damage to the gears or injury to the fingers. The best solution is to turn the device upside down, pre-laying soft tissue on the work surface so as not to scratch the body.
It's critical to make sure you're using the type of tank that's compatible with your vacuum cleaner modification. There are many accessories on the market, but only original or certified modules ensure that the contacts are properly fitted and the system is tight. Poor analogs can leak, causing the main board to short, so saving on this component is unacceptable. Check the labeling on the bottom of the device and compare it with the description of the accessory you purchase.
💡
Use only distilled or well-filtered water to prevent scale from forming on the pump and membrane, which will significantly extend the life of the device.
It is also worth preparing a dry wipe made of microfiber and a container of water before installing a new tank, it is recommended to wipe the compartment inside the robot from dust that may have gotten there during previous cleanings. The presence of foreign objects or wool lumps in the shaft of the tank installation can disrupt the tightness of the connection and lead to errors in the operation of water level sensors.
Instructions for installation of water tank
The process of replacing a regular dust container with a combined water tank requires care, but it doesn't take long. First, tap the cap lock on top of the case and remove the standard dust collector. Notice how it was installed to properly orient the new module. The orientation of the contacts and latches must be identical, otherwise you risk damaging the plastic mounts.
☑️ Algorithm of module installation
Take your wet cleaning tank and make sure the water supply valve is closed (if it has a mechanical plug). Carefully insert the module into the vacant compartment, guiding it along the rails until the characteristic click. Do not put excessive effort: if the tank does not enter smoothly, check the correct angle of inclination. After installation, close the top cover of the device.
⚠️ Warning: Never try to pour water directly into the dust collector compartment without installing a special sealed module. HEPA Or the engine will cause irreversible damage.
After the physical installation, you need to check whether the robot has correctly identified the new type of cleaning. In some versions of the firmware, when installing a water tank, the device automatically goes into combined cleaning mode. If this does not happen, you will need to manually change the settings in the application, which will be discussed in the following sections. Visual control of the installation is mandatory: the tank should not protrude above the level of the housing.
Filling the tank and adjusting the supply
The process of filling the tank with water seems trivial, but the Xiaomi Vacuum 1C has its own nuances: the water tank usually has a rubber cap that must be tightly closed after filling. It is important not to transfuse water above the MAX mark, because when shaking while the robot is moving, excess can get into the ducts. It is optimal to leave a small air gap to compensate for the pressure.
The water intensity is not controlled mechanically, but by software through the Mi Home app. In the device management interface, you will find a slider or a choice of three levels: low, medium and high. Low is designed to keep surfaces clean on a daily basis that have no visible contaminants. Medium mode is suitable for standard cleaning, and high mode is suitable for removing dried stains.
| Feeding level | Water flow rate (ml/min) | Recommended coverage | Tank time. |
|---|---|---|---|
| Low. | ~60-80 | Tiles, laminate (daily) | Up to 100 minutes. |
| Medium. | ~90-110 | Linoleum, stone (standard) | Up to 80 minutes. |
| High-pitched | ~120-140 | Severe pollution, kitchen | 60 minutes. |
It's worth noting that this model only delivers water by accident or under a little pump pressure while it's moving, and when the robot is standing still or returning to base, it shouldn't be supplied. This is implemented to prevent puddles from forming. If you notice that there's a puddle left under the robot after cleaning, check the density of the rag and the level of supply in the settings.
Customization of cleaning modes in the Mi Home application
To fully utilize the floorwashing function, you need to synchronize the robot’s actions through your smartphone. Open the Mi Home app, select your Xiaomi Vacuum 1C and go to the control menu. Here you will see a room map (if built) and the main start buttons. To activate the water supply, you often need to switch from Vacuum Only to Vacuum + Water or the like.
In the cleaning settings (Settings → Cleaning settings), you can find parameters that control the behavior of the device when there is a water tank. Some users prefer to turn off suction at maximum power during wet cleaning to save battery power, since the pump also consumes energy. Optimizing algorithms allows you to achieve a balance between the quality of the wipe and autonomy.
If the robot vacuum cleaner can't see the installed tank, try restarting the device by holding the power buttons. In rare cases, you need to update the firmware to the latest version, as the old algorithms may not correctly recognize new accessories. Make sure that the application selects the correct region and device model, as the functionality may differ.
⚠️ Note: Do not leave water in the tank longer than on 2-3 Stagnant water can bloom, causing unpleasant smells and bacteria to multiply inside the tube system.
Choosing and caring for a microfiber napkin
The quality of wet cleaning depends on the condition and type of fabric used. The tank usually comes with one or two wipes that are attached to Velcros or special clips. Microfibre is the optimal material, as it absorbs dirt well and does not leave villi on the floor. Using conventional cotton rags can reduce the efficiency of cleaning and clog filters faster.
After each cleaning, it is recommended to remove the fabric, rinse it with warm water and dry it thoroughly. A wet wipe left on the tank or in the robot compartment will be the ideal environment for mold development. In addition, wet fabric can oxidize the metal parts of the tank attachment. Regular washing at a temperature of no more than 40 degrees without using linen conditioners will retain the absorbent properties of the material.
How often do you change a napkin?
There are also disposable wipes with detergent that can be attached to a reusable microfiber, which is a convenient option for disinfecting floors or removing greasy stains in the kitchen, but it is more economical and environmentally friendly to use reusable options for daily use, regularly washing them in the washing machine.
Typical errors and troubleshooting
Even if you follow all the instructions, users can run into problems. One of the most common is that the robot reports no water, even though the tank is full. This can be due to clogging of the tank's outlet or oxidizing the sensor contacts. Cleaning the hole with a thin needle or soft brush often solves the problem. It is also worth checking whether the silicone hose inside the tank is twisted (if the design is collapsible).
Another common mistake is the appearance of stripes on the floor, which indicates that the cloth is unevenly fitting or the water level is too low. Make sure the cloth is stretched evenly and does not gather into the folds behind the robot. If the stripes remain dry, try increasing the feed intensity in the application or replacing the napkin with a fresher one.
In case the robot starts leaving puddles, stop cleaning immediately. Check if the rubber valve of the tank is damaged and tightly closed. Perhaps the supply level is too high for your type of flooring. Wooden floors and laminate require minimal moisture, while the tile withstands more intensive processing.
💡
Regular prevention of water supply system (washing the tank, replacing filters, drying rags) prevents 90% of possible malfunctions and prolongs the life of the device.
If none of the methods work, and the robot continues to make errors or work incorrectly with the water tank, the module itself or the internal pump of the robot may not work, in this situation, it is recommended to contact an authorized service center for diagnosis. Do not try to disassemble the pump yourself if you do not have relevant experience, as it is a complex mechanical system.
