How to set up and start wet cleaning with Xiaomi robot

Modern home automation devices make life much easier, but their functionality is often underestimated due to the wrong initial setup. Many owners of Xiaomi smart appliances face a situation where the device simply collects dust, although its capabilities also allow you to wash the floors, removing dried stains.

It is not enough to simply attach a water tank to the wash mode correctly. The electronics of the gadget must receive a signal that the wet cleaning platform is installed, otherwise the program will be blocked or run in dry mode. Ignoring this rule may lead to the fact that you spend time preparing, but do not get the desired cleanliness result.

In this detailed guide, we’ll take you through all the nuances of operation, from installing the module correctly to controlling the subtleties of Mi Home, and learn how to avoid the typical mistakes that beginners make and how to extend the life of the device using it at full capacity.

Before you get to specifics, make sure your robot vacuum cleaner technically supports wet cleaning. Not all models, even in the Xiaomi or Roborock lineup, are equipped with electronic water control. Some budget versions have only a mechanical platform that you need to buy separately, and more advanced models are already bundled with everything you need.

Verification of the completeness and preparation of the device

The first step is to physically inspect your device, and you need to flip the robot over and make sure that the main dust container is removed and you plan to install a combined tank or a separate water module in its place, and the design of the housing of different models may differ: in some cases it is a single 2-in-1 unit, in others it is a removable panel.

Carefully inspect the bottom of the device. There should be a mount for a platform with a cloth. If you see only a brush and wheels, but there is no mounting area, you may need to buy a compatible accessory. Without a properly secured platform, the sensors may not recognize the wash mode.

⚠️ Warning: Never attempt to start a robot with a water tank installed unless the main dry garbage container is removed from it.This can cause moisture to enter the turbine engine and the device to fail.

Make sure that a special microfiber wipe is included.Using regular rags or rags is not recommended, as they may have a too long pile that winds over the side brush.The microfiber provides optimal grip on the surface and efficiently collects fine dust.

Installation of the platform and water pouring

The installation process requires care. Take a water tank and make sure the rubber plugs on the fluid supply holes are tightly closed. Open the valve and pour clean tap water. The water temperature should not exceed 40 degrees so as not to damage the internal seals and the pump.

It is not recommended to use hot water or add detergents to the tank unless it is expressly authorized by the instructions for your particular model. Aggressive chemistry can corrode plastic and lead to leaks, as well as clog thin pump channels. For better cleaning quality, it is better to use special liquids designed specifically for robotic sinks.

Once the tank is filled, close the valve tightly. Now gently insert the module into the robot body. You should hear the characteristic click or feel the platform stand in place. On some models, such as the Xiaomi Vacuum-Mop Essential, the platform is fixed by magnets, and you just need to put it on top, combining the contacts.

Now, attach a wet wipe to the bottom of the platform, which is usually fixed with Velcros or special pinches at the corners, and it's important that the fabric is evenly stretched and does not hang on the sides, otherwise the robot can get stuck on the doorsteps or carpets.

💡

Use only soft water or water that has passed through a filter jug. High-salt hard water quickly forms scale inside the pump, which reduces pressure and can disable the pump after months of active use.

Setting up parameters in the Mi Home app

After the physical installation, you need to set up the device software. Open the Mi Home app on your smartphone and go to the management page of your robot vacuum cleaner. The interface may vary depending on the firmware version and the server region, but the basic principles remain similar.

In the top menu or in the additional settings (three dots in the corner), find the item responsible for selecting the cleaning mode. You need to activate the function "Wet Cleaning" or "Mopping." If this item is inactive or hidden, check whether the tank is installed correctly. Some models automatically detect the presence of water, others require manual inclusion in the menu.

Pay special attention to adjusting the water supply level. The app usually offers three or four options: low, medium, high and intelligent. Intelligent mode itself adjusts the fluid supply depending on the speed of the robot, but for severe contaminants, it is better to choose the maximum level manually.

You can also find a "Wash only" or "No suction" option in the settings, which is useful if the floor is already clean from dust, but there are sticky spots, in which case the turbine will not work, which will save battery power and reduce noise.

Choosing Cleaning Mode and Starting

When all the parameters are set, you can start. On the app's home page, select the type of cleaning. Quiet or Standard mode is best for wet flooring. In Maximum mode, the robot will move faster, which can reduce the effectiveness of stain washing, since the rag will have less time to contact a particular site.

If you have a map-building model, you can choose a zone cleaner, which is especially true for a wet sink: often you only have to wash the kitchen or the hallway, leaving the rest of the rooms dry, just highlight the area on the map with your finger and press the start button.

Once launched, the robot will start moving around the perimeter or spiral, gradually moisturizing the floor. Watch the first minutes of work to make sure that the water is supplied evenly and does not form a puddle. If you notice excess moisture, immediately reduce the level of supply in the application.

Features of cleaning on different types of coatings

Not all flooring responds equally to wet cleaning. Laminate flooring and parquet require caution. Although modern Xiaomi robots supply water in small portions, leaving them alone on a long carpet or cheap laminate without lacquer can be risky.

For these cases, there are virtual walls or magnetic tapes (depending on the model), you can prevent the robot from entering certain areas or, conversely, force it to pass the carpets. In the Mi Home app, this feature is called Virtual Walls or No-go zones.

⚠️ Warning: If you have long-pile carpets in your house, be sure to set up restricted areas. Even in wash mode, a robot may try to drive onto the carpet, wet it, and dust the pile from the main brush.

Tile and granite, by contrast, are ideal for wet robot cleaning. You can safely use the maximum water supply. A smooth surface allows the robot to slide easily, and the high temperature of the water (if it is served at room temperature) helps to dissolve fat faster in the kitchen.

Post-cleaning maintenance and care

Once the wet cleaning cycle is complete, you can't leave the device alone. The residue of water in the tank is the perfect environment for bacteria to multiply and produce an unpleasant musty odor. Immediately after work, remove the module and pour out the unused water.

Remove the cloth and wash it. Even if it looks clean, it retains microparticles of dirt and fat. It is recommended to dry the cloth in its straightened form so that it does not lose shape. Regular washing prevents the appearance of swelling on the floor at the next cleaning.

Once a month, do a preventive cleaning of the tank itself. Wash it with clean water, make sure the outlet holes are not clogged with scale. If you live in a region with very hard water, you can use a weak solution of citric acid to remove the lime plaque, but then thoroughly rinse the container.

💡

The main secret of a long-term service robot washer is never to leave water in the tank after cleaning is completed and always remove the wet cloth for drying.

Frequent problems and ways to solve them

Sometimes users are faced with the robot stops supplying water or does it unevenly. The first reason is usually a traffic jam in the supply system. Try pressing the water supply valve several times or shaking the tank slightly to remove the air.

The second common problem is that the robot thinks the tank is empty even though there is water, and this can happen if the contacts on the tank and in the body of the robot are oxidized or contaminated, wipe them with dry soft cloth, and also check if the tank lid is tightly closed: in some models, the water level sensor responds to depressurization.

If the robot leaves dry stripes in the middle of the floor, it may not fit well or dry. Try to moisten the napkin more before you start working or increase the intensity of the water supply in the application settings. Also check if the hair is wound on the platform shafts, which interfere with the tight fit.
