How to start wet cleaning in the robot vacuum cleaner Xiaomi Dreame F9: instructions with photos and tips

Xiaomi Dreame F9

step-by-step

Wet cleaning in Dreame F9 requires a different approach than dry cleaning: it is important to set the water tank correctly, adjust the flow rate and choose the appropriate mode. If you ignore these nuances, the result can be disappointing, from poorly washed stains to damage to flooring. We will show you how to avoid typical errors and achieve perfect cleanliness without undue effort.

The Dreame F9 features an electronic humidity control system that automatically adjusts the water supply depending on the type of floor, but even with this smart feature, the user needs to monitor the condition of the accessories and prepare them correctly, for example, using ordinary tap water instead of distilled water can lead to plaque on the sensors and shorten the life of the robot.

Preparing the robot for wet cleaning: what to do before the first launch

Before you start cleaning, make sure your Dreame F9 is fully prepared for this procedure. Start by checking the package: the box should have a special water tank, a washing wipe (microfibre nozzle) and a guide plate for even distribution of moisture. If something is missing, do not risk using improvised means, this can damage the mechanism.

First, remove the main dust collector (which is only used for dry cleaning) and install a water tank in its place. Pay attention to the sealing gum, which must fit tightly to the case, otherwise water will leak out. Also make sure that the container does not contain any foreign objects or residues of detergent from previous cleanings.

• 🔧 Check the integrity of the washing wipe: it should not have holes or badly worn edges.
• 💧 Use only distilled or boiled water: tap water contains salts and chlorine, which over time clog the nozzles and spoil the sensors.
• 📱 Update the firmware of the robot: older versions of the software may have bugs that interfere with the correct operation of the wet cleaning system.

If you use a detergent (such as a special concentrate for robot vacuum cleaners), add it to the water strictly according to the instructions. Excessing the dosage leads to abundant foaming, which can disable the Dreame F9 sensors. For the first run, it is better to do without chemistry so you can assess the basic efficiency of cleaning.

Installation of accessories: step-by-step instructions with photos

The correct installation of a water tank and a washing wipe is key to a successful cleaning.

1. Open the top cover of the robot by pressing the latch.
2. Remove the dust collector (if installed) and put it aside.
3. Insert the water tank into a special compartment before you click, make sure it sits flat, and it can cause leaks.
4. Pour water into the tank without exceeding the MAX mark (usually 200-250 ml).

Now we turn to the washing napkin:

1. Remove the lower protective cover of the robot (it is attached to the latches).
2. Install a guide plate for water - it should fit tightly to the base.
3. Put a microfiber wipe on the plate, aligning it around the edges, make sure the fabric is not twisted and does not cover the vents.
4. Fix the napkin with Velcro or clamps (depending on the model).

After installation, make sure that the napkin does not interfere with the rotation of the side brushes and does not cling to the wheels. If the fabric is too long, cut it with scissors, leaving a supply of 1-2 cm at the edges.

Setting up wet cleaning modes in the Mi Home app

The Mi Home app allows you to flexibly adjust the wet cleaning options, but many users are unaware of the hidden features. For example, Dreame F9 has three water intensity levels:

• Weak - for laminate and parquet (minimum humidity, suitable for delicate coatings).
• Medium - for tiles and linoleum (the optimal balance between purity and safety).
• Strong for persistent contaminants (use carefully, only on water-resistant surfaces!).

To change the settings:

1. Open the Mi Home app and select your Dreame F9.
2. Go to the section Cleaning Settings → Wet cleaning.
3. Select the intensity level and activate the Zigzag route option if necessary for more thorough handling.
4. Save the changes and send the robot to clean up.

If the app doesn’t have a separate item for wet cleaning, upgrade the Mi Home to the latest version or reset the robot to the factory version. Also check that the floor type menu indicates the correct coating – this depends on the water supply algorithm.

💡

If the robot leaves a strip of water, reduce the feed intensity by one level and check if the nozzles are clogged in the tank, and you can clean them with a toothpick or compressed air.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when cleaning wet, and here are the most common ones and ways to solve them:

Another common problem is that the robot starts to tow on the wet floor, and this is because the wheels lose traction to the surface, so to avoid this, turn on Turbo mode for dry cleaning after wet, so the Dreame F9 will collect the excess moisture and return the grip.

Care for accessories: how to extend the life of the washing system

To ensure that wet cleaning is always effective, you need to regularly maintain Dreame F9 accessories.

• 🧼 Wash the water tank after each cleaning: the residues of liquid and detergent contribute to the reproduction of bacteria.
• 🧻 Wash the washing wipe by hand: machine washing spoils the microfiber.Use delicate mode without bleach.
• 🔄 Change the napkin every 3-4 months: even with careful care, the fabric wears out and loses absorbent properties.
• 💦 Dry the robot after cleaning: leave it with the lid open for 1-2 hours to evaporate moisture.

Pay special attention to the guide plate: it must be cleaned of plaque and dust once a week, use a soft brush or cotton swabs to do this, if the plate is deformed (for example, from high temperature), replace it, otherwise the water will be distributed unevenly.

If you use a detergent, flush the container with vinegar solution (1 tbsp. vinegar per 1 liter of water) once a month. This will remove the lime plaque and prevent nozzles from clogging. Don't use abrasive cleaners - they scratch the plastic!

💡

Regular care of accessories not only improves the quality of cleaning, but also prevents breakdowns, for example, clogged nozzles are one of the most common reasons for contacting a service center.

Combination of wet and dry cleaning: the optimal algorithm

Many users are unaware that the Dreame F9 can automatically alternate dry and wet cleaning in one cycle.

1. Install both a water tank and a dust collector (if your model supports simultaneous installation).
2. In the Mi Home app, select Combined Cleaning mode.
3. Set up the order of action: first dry cleaning (to collect large debris), then wet.

This approach is especially effective in the kitchen, where the floor can be crumbs and sticky spots. However, note that combined cleaning increases the cycle time by 30-40% and consumes battery power faster. If the area is more than 50 m2, it is better to divide the processes into two separate starts.

If the robot starts to “mix” between modes (for example, washing the floor without collecting dust), check:

• Are both containers (vacuum and water container) properly installed?
• Is the dust collector overloaded (when filled by more than 80%, the robot can skip dry cleaning).
• Is the firmware relevant (in older versions there were bugs with alternating modes).

💡

For better results, before combined cleaning, vacuum the floor by hand or walk through it with a dry brush, which will reduce the load on the robot filters and improve the quality of washing.

Safety: What Surfaces Can You Wash Dreame F9?

Not all flooring is compatible with wet cleaning, and here is a list of permitted and prohibited materials:

⚠️ Attention: If your dream is yours F9 Avoid certain areas for no apparent reason, check the settings for the type of floor in the app, and the robot may think it's a carpet, when it's actually just dark tiles, in which case manually mark the problem area as "washing allowed».

To test the reaction of the coating to moisture, conduct a trial cleaning in a small area (for example, in the corner of the room). If after 10-15 minutes there are no scuffs or bloating on the floor, you can start a full cleaning.
