How to start wet cleaning on Xiaomi robot vacuum cleaner: the complete guide

Xiaomi 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 cleaning the floors. However, many users face problems when first starting: the tissue wipe remains dry, the robot ignores the cleaning areas, the water flows unevenly. In this article, we will understand how to properly activate wet cleaning on different Xiaomi models (including Mi Robot, Viomi and Dreame), what settings affect the quality of washing, and how to avoid typical errors.

Wet cleaning requires a special approach: here it is important not only to press the button in the application, but also to prepare the robot, choose the optimal mode, and sometimes even update the firmware. For example, in models Xiaomi Mi Robot Vacuum-Mop 2 Pro cleaning algorithm is radically different from the budget versions, and in DreameBot W10 We've analyzed official instructions, user feedback and hidden features to gather the most complete guide, from basic actions to advanced life hacks.

If your Xiaomi robot vacuum cleaner already has a water tank, but you haven't tried wet cleaning yet, this article is for you. And if it's working "something wrong," here's a solution to typical problems and ways to optimize the process.

1.What Xiaomi models support wet cleaning?

Not all Xiaomi robot vacuum cleaners can wash floors, and the wet cleaning feature is relatively recent and available in the following series:

• 🤖 Mi Robot Vacuum-Mop: All models (P, 2, 2 Pro, 2 Ultra, E10 etc.) – universal robots with combined cleaning.
• 🧹 Viomi V2/V3: Budget options with a basic module of wet cleaning.
• 💧 DreameBot (W10, D9, L10 Pro et al.: premium models with advanced settings (e.g., wash intensity adjustment).
• 🔄 Xiaomi Sweeping Robot (old models): dry cleaning only, wet - not supported.

To find out if your robot has a wet cleaning function, check:

1. The presence of a water tank (usually white or transparent) on the back or side panel.
2. Mop button/icon in the Mi Home or Dreame app.
3. A cloth wipe in the kit (sometimes sold separately).

⚠️ Note: If your robot is from the Mi Robot Vacuum series (without prefix) -Mop), It's only for dry cleaning, and trying to put water in the dust collector will cause it to break!

2. Preparing the robot for wet cleaning: a step-by-step checklist

Before the first wet cleaning operation, the robot must be properly assembled and configured, and skipping at least one point can lead to leaks, poor quality washing, or even damage to equipment.

Set the water tank in place (before clicking)

Attach a tissue napkin to the bottom of the robot

Fill the tank with water (not above the maximum mark)

Check that the water supply valve is not blocked

Make sure that the application has wet cleaning mode enabled-->

Let’s look at each item in more detail:

1. Installation of a water tank. In most models, it is attached to the back, under the lid.

• 🔹 Check that the sealing gum is in place (prevents leaks).
• 🔹 Don’t pull over the mounts – this can warp the plastic.
• 🔹 In the DreameBot models W10 The tank has two compartments: for water and for detergent (if supported).

2. Napkin attachment. The tissue nozzle should fit tightly to the bottom of the robot.

• 🧼 Microfiber wipe - for standard cleaning.
• 🧽 Abrasive nozzle (in premium models) - for persistent pollution.

If the wipe broke or lost shape, it can be replaced with a similar one (for example, Viomi is suitable for most Xiaomi models).

3. Refill with water. Use only pure water (better distilled or boiled) in detergent-enabled models (e.g. DreameBot) L10 Pro can be added a special solution (but not more than 10 ml per 200 ml of water).

⚠️ Warning: Never put harsh chemicals (bleach, vinegar, alcohol) into the tank. This destroys seals and can disable the water supply pump.

3.How to start wet cleaning through the Mi Home app

The main way to manage is through the official Mi Home app (or Dreame for the same models). The interface may vary slightly depending on the firmware version, but the overall algorithm is the same.

Step 1: Connect the robot to the application.

• 📱 Open Mi Home, press. + → Addition of a device.
• 🔍 Select the category "Cleaning" and find your model.
• 📶 Connect the robot to Wi-Fi (2.4 GHz network only!).

Step 2. Selecting a cleaning mode.

In the main menu of the device, find the Clean (or Clean) tab.

• 🧹 Dry cleaning (vacuum cleaner only).
• 💦 Wet cleaning (washing only).
• 🔄 Combined (vacuum cleaner) + wash).

Step 3: Set the intensity.

In premium models (e.g. Mi Robot Vacuum-Mop 2 Pro) you can adjust:

• 🌊 Water level (low/medium/high).
• 🔁 Number of passages per place (for persistent pollution).
• 📍 Cleaning areas (you can exclude carpets).

Step 4, launch.

Click Start Cleaning and select:

• 🏠 Complete cleaning (all rooms).
• 📌 Zone (select the area on the map).
• 🔄 Scheduled (set up automatic start-up).

💡

If the robot ignores wet cleaning, check if the settings are "Vacciner Only" and sometimes this parameter is lost after updating the firmware.

4. Manual control: buttons on the robot body

You don't always have a smartphone on hand, and fortunately, you can activate the basic wet cleaning functions through physical buttons on the robot body, and let's look at the popular models.

Some models (such as DreameBot) D9) combination-button:

1. Press Power (onset).
2. Then hold the Mode (mode) for 2 seconds until the water indicator lights up.
3. With a short press, switch modes: 🧹 (dry) → 💧 (humid) → 🔄 (combined).

⚠️ Note: In models without a display (for example, Viomi) V2) When you manually start wet cleaning, the robot will wash floors at a fixed intensity (usually average.

5. Wet cleaning settings: hidden features and life hacks

By default, the robot cleans the floors "as it happens," but in the settings you can optimize the process for your needs.

1. Map of premises and prohibited areas.

The Mi Home app can be used to:

• 🗺️ Divide the apartment into rooms (for selective cleaning).
• 🚫 Banning the robot from entering carpets during wet cleaning.
• 📍 Designate areas with severe pollution (robot will pass them) 2-3 once).

Water supply adjustment.

In electronically controlled models (e.g. Mi Robot Vacuum-Mop) 2 Ultra available 3-4 intensity:

• 🌊 Low - for laminate and parquet (minimum moisture).
• 🌊🌊 Medium - for tiles and linoleum.
• 🌊🌊🌊 High for persistent pollution (divorce risk!).
• 🌊🌊🌊🌊 Maximum (only in DreameBot) - with detergent.

3. Cleaning schedule.

So that the robot washs the floors automatically:

1. In the app, go to the Schedule → Add the task.
2. Choose the days of the week and the time.
3. Specify the type of cleaning: Wet or Combined.
4. Save the settings.

💡

DreameBot models have a function called Adaptive Water Supply, where the robot automatically increases the intensity in dirty areas (detects by sensors). → Cleaning regimes.

Typical problems and their solutions

Even if you set it up properly, wet cleaning may not work perfectly, and we'll look at the most common user complaints and how to address them.

Problem 1: The robot doesn’t wash the floor (the napkin stays dry).

Possible causes and solutions:

• 🔧 Clogged water supply valve, wash the tank under running water and check the supply hole.
• 🔋 Weak battery power. Wet cleaning requires more power - charge the robot to 100%.
• 📱 App crash: Restart Mi Home or reconnect the robot.
• 🛠️ The pump is broken. If nothing works, call the service.

Problem 2: There are still divorces on the floor.

What to do:

• 🧼 Use distilled water (usually many salts that leave a trace).
• 🔄 Reduce the intensity of water supply in the settings.
• 🧽 Change the wipe to a denser one (for example, from high-density microfibers).
• 🧹 Walk after the robot with a dry mop (especially on the laminate floor).

Problem 3: The robot avoids wet cleaning on carpets, but washes them around the edges.

Decision:

1. In the app, mark the carpets as Zones without cleaning (in map editing mode).
2. If you have a short-pile carpet, turn on the option of Washing Carpets (available in DreameBot). W10).
3. Make sure the height sensors are not contaminated (wipe them with a dry wipe).

Problem 4: Water is not flowing uniformly (dry, then wet).

Reasons:

• 💧 There's air in the tank. Shake the tank a little before you start.
• 🛠️ Worn pump. Replacement required (at service center).
• 📉 Uneven floor. Robot loses contact with surface - check pressure sensors.

💡

If the robot started spitting with water (splashing around), the nozzle probably clogged. Remove the tank, wash it under the tap and blow the feed hole (you can use a can of compressed air).

7.Tips for caring for a robot after wet cleaning

To make Xiaomi robot vacuum cleaner last a long time, after each wet cleaning, perform simple actions:

Empty the water tank and dry it

Wash the napkin under running water (without powder!)

Wipe sensors and contacts with dry cloth

Check your hair for any hair that has been worn.-->

1. Cleaning the water tank.

Do not leave the water in the tank for a long time, this leads to:

• 🦠 Development of bacteria and mold.
• 🔧 Corrosion of metal parts (in cheap models).
• 💧 Folding in the feed system.

It is recommended to wash the tank after each use and dry it in air (not under direct sunlight).

2. Care for a napkin.

The fabric nozzle can be washed by hand (water temperature is not higher than 40).°C) or in the washing machine (in a bag for delicate things:

• 🧼 Bleach or aggressive powders.
• 🔥 Hot water (microfibre can sit down).
• 🧺 Drying in a machine (air drying only!).

3. Sensor maintenance.

Wet cleaning increases the risk of water getting to electronic components.

1. Wipe the height and collision sensors with a dry wipe.
2. Check the contacts of the charging station for oxidation.
3. Clean rollers and side brushes from wound hair.

4. Robot storage.

If you don’t plan to use the robot for more than a week:

• 🔋 Remove the battery (if possible according to the instructions).
• 💧 Pour water and dry all the details.
• 🏠 Store in a dry place at room temperature.

💡

In Xiaomi models with self-cleaning function of the tank (for example, Mi Robot Vacuum-Mop 2 Ultra), the tank is automatically washed with hot water after cleaning.
