Wet cleaning by Xiaomi Mi robot vacuum cleaner: the full guide 2026

Xiaomi Mi robot vacuum cleaners are no longer just smart brooms — modern models are equipped with a wet cleaning function that allows not only collecting dust, but also washing floors with minimal human participation. However, many owners face problems: laminated divorces, quickly contaminated wipes or uneven moisturizing. Why is this happening? The fact is that the effectiveness of wet cleaning depends not only on the technical characteristics of the device, but also on the correct setting, preparation of the room and care for accessories.

In this article, we will discuss all the nuances of wet cleaning on Xiaomi Mi robot vacuum cleaners (Mi Robot Vacuum-Mop, Mi Robot Vacuum-Mop 2, Mi Robot Vacuum-Mop 2 Pro, etc.), including mode selection, floor preparation, water tank care and solving typical problems.

Spoiler: If you think it's enough to just pour water and press "Start," then after reading this article, your approach to cleaning will change. For example, did you know that Xiaomi Mi robots with laser navigation automatically increase the pressure of the wipe on contaminated areas, but only if the moisture mode in the application is set correctly?

1.Which Xiaomi Mi models support wet cleaning?

Not all Xiaomi robot vacuum cleaners are able to wash floors, and the wet cleaning feature is available in the following series (relevant for models released after 2019):

• 🔹 Mi Robot Vacuum-Mop (first generation, base model with 200 ml capacity)
• 🔹 Mi Robot Vacuum-Mop 2 (Enhanced navigation, adjustable water pressure)
• 🔹 Mi Robot Vacuum-Mop 2 Pro/Ultra (automatic washing of napkins, heating of water)
• 🔹 Mi Robot Vacuum-Mop P (budget version with simplified humidification system)
• 🔹 Mi Robot Vacuum-Mop 2 Lite (compact model without drying function)

To check if your model supports wet cleaning, look at the specifications in the Mi Home app (Device section). → Information) or look at the body of the robot – models with this function have a special compartment for water and a mount for a napkin.

Important! Even if your robot can wash floors, not all flooring is suitable for wet cleaning, such as flooring, unlaminated board or carpets with pile, it is better to exclude from the cleaning area or use a minimum level of moisture.

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

Before sending the robot to wash the floors, follow a few mandatory steps to help avoid divorces, breakages and premature wear of accessories.

Step 1. Set a water tank and a napkin.

• 💧 Remove the dust collector and install a water tank (usually included) in its place.
• 🧼 And you can attach a wet cleaning wipe to the bottom of the robot, and it should be flat, without folding.
• ⚠️ Don't use regular rags! Only special wipes with microfibre (article) ZNMSJ01ZM They absorb water better and leave no villi.

Step 2: Pour water and detergent (optional)

• 🚰 Pour distilled or boiled water into the tank (volume depends on the model, usually 200-300 ml). Do not use tap water - it leaves lime plaque on the parts.
• 🧴 If you want to add detergent, use only special concentrates for robot vacuum cleaners (for example, Xiaomi Mi Robot Detergent.

Step 3: Set up the moisture mode in the app

Open Mi Home, select your robot and go to Cleanup Settings → Wet cleaning. You can choose one of the modes here:

• 🌊 Weak (for laminate, linoleum)
• 💦 Medium (universal for most coatings)
• 🌊🌊 Strong (for persistent contamination on the tile)
• 🔄 Auto (the robot itself regulates the pressure depending on the type of gender)

3. How to properly prepare the room: what to remove and what to leave

Xiaomi Mi robot will only clean the room properly, and this is what you need to do before launch:

Get off the floor:

• 🧦 Small objects: socks, toys, wires, papers, and a robot can hook them with a napkin and smear dirt.
• 🧶 Carpets with a high pile. Wet wipes will cling to the villi, and the robot will spend a lot of time trying to "cross" the obstacle.
• 💩 Large debris: sand, crumbs, animal hair. First, take a regular vacuum cleaner or turn on dry cleaning mode.

Pay attention to the coverage:

Advice for pet owners: If you have pets, walk on the floor with a sticky roller before cleaning - this will remove the wool that the robot can smear with a wet napkin.

💡

If there are areas in the house that do not need to be washed (such as a living room carpet), set up the "no-go zones" in the Mi Home app. → Add a zone → Type: Don't wash.

4. Step-by-step instructions: how to start wet cleaning

Now that you're done, you can start cleaning. Here's a step-by-step algorithm for Xiaomi Mi Robot Vacuum-Mop. 2/Pro (Other models may have different steps):

Step 1. Select the type of cleaning

In the Mi Home app, click Cleanup → Select a mode and set up:

• 🧹 Wet cleaning only (if the floor has already been swept)
• 🧹💦 First vacuum cleaner, then mop (recommended for severe contamination)
• 🔄 Alternation (the robot will alternately vacuum and wash)

Step 2. Set the intensity.

In the section Cleaning settings → Choose a wet cleaning:

• 🌊 Water level: weak/medium/strong/auto
• 🔄 Number of passes: 1-3 (the dirtier the floor, the more passes)
• 🕒 Cleaning time: indicate if you want a delayed start

Step 3. Start cleaning.

Press the Start in the app or the button on the robot body. If you have a model with an automatic wipe wash (for example, Mi Robot Vacuum-Mop 2 Ultra), the robot will rinse the cloth itself during the cleaning process.

Step 4: Follow the process

For the first few cleanings, watch the robot:

• ✅ He should move evenly around the room without getting stuck.
• ✅ The napkin should remain wet, but not wet (no puddles).
• ❌ If the robot begins to "snag" in one place - check whether the napkin clings to irregularities.

5. Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that reduce the efficiency of wet cleaning, and here are the most common mistakes and ways to correct them:

Mistake 1: Using a regular cloth instead of a special wipe

⚠️ Attention! Cloth rags or microfiber wipes for manual cleaning are not suitable! They get wet quickly, leave the pile and can damage the mounting mechanism. Use only the original Xiaomi wipes (article) ZNMSJ01ZM magnetically-mounted).

Mistake 2: Pouring tap water

The tap water contains salts and chlorine that settle on the inside of the robot and clog the nozzles. Use only distilled or boiled water. If you have hard water, rinse the tank once a month with vinegar solution (1:1 with water).

Mistake 3: Incorrect level of hydration

Too much water pressure leads to laminated swelling, and too little water does not clean up pollution.

• 🟢 Laminate/linoleum → weak-middle
• 🟢 Tiles/stone → medium-grade
• 🔴 parquet/carpet → dry-cleaning

Mistake 4: Ignoring Robot Care

After each cleaning:

• 🧼 Wash the napkin under running water and dry it.
• 💧 Empty and wipe the water tank.
• 🔧 Clean the water supply nozzles (use a toothpick or compressed air).

💡

Regular care of the napkin and water tank prolongs the life of the robot and prevents the appearance of an unpleasant odor.

6 Hidden features in Mi Home: how to improve the quality of cleaning

Mi Home offers a few hidden settings that will help make wet cleaning more efficient, and most users don't know about them, but they have a significant impact on the outcome.

Function 1: Configure zones with different levels of humidity

If the house has rooms with different coatings (for example, tiles in the kitchen and laminate in the bedroom), you can set individual settings for each zone:

1. Open the map at Mi Home.
2. Click Add Zone and circle the desired area.
3. Select Cleaning Type: Wet and set the water level.

Function 2: Deep Cleaning Mode

Some models (such as the Mi Robot Vacuum-Mop 2 Pro) have a hidden Deep Mop mode that increases the pressure of the wipe on the floor.

1. Go to the cleaning settings → Additionally.
2. Enable the option of Enhanced Wet Cleaning.
3. Start cleaning manually (in automatic mode this mode does not work).

Function 3: Scheduled delayed start

If you want a robot to wash floors when you are not home, set up a schedule:

• 🕘 Go to the schedule. → Add a challenge.
• 📅 Choose the days and times (for example, daily at 10:00 am).
• 🔄 Specify the type of cleaning: Wet or Combined.

Function 4: Voice control

If you have a Xiaomi Smart Speaker or a smartphone with Alice, you can start cleaning with your voice.

1. Connect the robot to the Mi Home ecosystem.
2. Say, "Alice, start the wet cleaning in the living room."

💡

If your robot is often "lost" during cleaning, update the map of the room. To do this, transfer it to the charging station, then click Settings in the application. → Reset the card and start cleaning again.

7. Robot care after wet cleaning: extending service life

To make the Xiaomi Mi robot vacuum cleaner last longer, after each wet cleaning, perform the following actions:

1. Cleaning the napkin.

• 🧼 Wash the napkin in warm water with a mild detergent.
• 🚫 Do not use bleach or aggressive chemicals – it destroys the microfiber.
• ☀️ Dry the napkin in the air (not in the dryer!).

2. Care for the water tank

• 💧 Empty the tank and rinse it under running water.
• 🧽 Once a week, clean the tank with acetic solution (1: 1) to remove plaque.
• ❄️ If the robot is not used for a long time, drain the water and dry the tank.

Cleaning of nozzles and sensors

• 🔧 Clean the water supply holes with a toothpick or compressed air.
• 👁️ Wipe sensors (especially laser or camera) with a soft cloth.
• 🧲 Check the magnetic attachments of the wipe – they should not be covered with rust.

4. Robot storage

• 🏠 Keep the robot at the charging station in a dry place.
• 🔋 If you haven’t used the robot for more than a week, remove the battery (if possible according to the instructions).

⚠️ Attention! If the robot makes unusual sounds (squeaking, crackling) or leaves stripes after wet cleaning, it may indicate that water has entered the mechanical parts, in which case immediately stop cleaning, dry the robot for 24 hours and check the tank's sealing gums.

8. Frequent problems and their solutions

Even when you're properly operated, there can be difficulties, and let's look at some of the most common problems and how to fix them.

Problem 1: Robot does not wash the floor (napkin remains dry)
