How to enable wet cleaning on the Xiaomi Vacuum Mop robot vacuum cleaner: the complete guide

Xiaomi’s wet cleaning robots (Vacum Mop P, S7, X10, and others) are not only able to collect dust, but also wash floors — but many users face problems when they first turn on this mode. Unlike dry cleaning, it requires you to properly install the water tank, adjust the humidification intensity and make sure the model supports the function. This article will help you understand everything from robot preparation to the intricacies of control through the Mi Home app.

It’s important to understand that not all Xiaomi models are equipped with wet cleaning function – for example, basic versions of Vacuum Cleaner (without the Mop in the title) can not wash floors. We will discuss in detail how to determine the compatibility of your model, what accessories are needed to get started, and why sometimes the robot refuses to turn on the wash mode even with the right settings.

1. Model Compatibility Check: Does your Xiaomi support wet cleaning?

Before you try to turn on the wash mode, make sure that your Xiaomi model supports this feature at all.The brand’s lineup includes both hybrid devices (vacuum cleaner + mop) and conventional vacuum cleaners.

• 🔍 The name of the model contains the words Mop, Pro or Plus (for example, Xiaomi Mi Robot Vacuum-Mop P, S7 Pro Ultra).
• 💧 In the configuration there is a water container (usually white or transparent color with a lid).
• 🧹 On the bottom panel of the robot there is a fastener for a cloth (plastic or metal plate with clamps).
• 📱 In the Mi Home application, there is a tab Wet Cleaning or Mopping in the device settings.

If your model doesn’t fit at least one of the items, it’s meant to be dry cleaning only, and trying to turn on the sink on these devices will lead to errors or breakage. For example, the Xiaomi Mi Robot Vacuum 1S (without the Mop in the name) does not support the feature, despite its similarity to hybrid models.

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

Even if your model supports floor washing, it is not enough to just pour water into the tank. Incorrect preparation can lead to leaks, poor cleaning quality or damage to the device.

And you'll pay special attention to the cleaning cloth, and you'll have a microfiber wipe that you want to use.

1. Spread and remove all threads/villi (they can clog the pump).
2. Fix on the plate so that the edges do not hang (otherwise the robot will "cling" to the furniture).
3. Wash before first use under running water (this will remove factory impregnation).

⚠️ Warning: Never use regular rags or dust wipes! they are not designed for wet cleaning and can:

• 🚫 Clogged water supply system.
• 🚫 Leave divorces on the floor.
• 🚫 Lead to overheating of the engine due to increased friction.

3. Step-by-step instructions: how to enable wet cleaning through the Mi Home app

Manage the wash mode through the official Mi Home app (or Xiaomi Home for new models). If you haven't already connected the robot to the app, do it via Add Device → Quick connection.

1. Open the robot card in the app and go to Clean (or Cleaning) section.
2. Choose the type of cleaning: 🧹 Dry cleaning (vacuum cleaner only). 💦 Wet cleaning (vacuum cleaner) + sink). 🔄 Hybrid cleaning (automatic switching between modes).
3. Adjust the water intensity (if available). Most models have 3 levels: 🌊 Low - for laminate and parquet. 🌊🌊 Medium - for tiles and linoleum. 🌊🌊🌊 High for severe pollution (divorce risk!).

Start cleaning.

Start

On models with an automatic base (for example, Xiaomi S7 Pro Ultra), water is supplied from a stationary reservoir, and its level is controlled by sensors, in which case an additional base wash item will appear in the application - it must be turned on every 1-2 weeks to clean the system of scale.

(1) Whether the water container cap is closed (the sensor blocks operation with the lid open).

(2) Whether the cloth is properly installed (its absence is recorded by the infrared sensor).

(3) Is there enough water in the tank (minimum 100 ml).-->

4. Wet cleaning settings: subtleties for different types of floors

One key parameter that many people miss is adapting the washing mode to the coating type, for example, for laminate, excess moisture can be harmful, and for bathroom tiles it is insufficient. The table below gives recommendations for popular coatings:

On Xiaomi models with laser scanning (for example, S7), you can create room maps and assign different wash settings for each room, for example, for the kitchen, set high water levels, and for a bedroom with laminate flooring – low. This is done in the Maps → room settings section.

💡

For carpeting, wet cleaning is contraindicated! the robot automatically shuts off the water supply if detects carpet (on models with a coating sensor).

5 Common Mistakes and How to Avoid Them

Even with the right setup, users often face problems: the robot does not wash floors, leaves divorces or gives out errors.

• 🚫 Robot doesn't spray water: Check if the pump filter is clogged (located under the water tank). Make sure the water is in the room temperature tank (cold can block the valve). Reboot the robot by holding the power button for 10 seconds.
• 🚫 Divorces: Use distilled water, hard water leaves white marks. Add 1-2 caps of a special cleaning agent for robot vacuum cleaners. Reduce the robot's speed in the settings (quick cleaning doesn't have time to absorb moisture).
• 🚫 No water error with a full tank: Remove the tank and check the seal ring for damage. Wipe the sensor contacts at the base of the robot with an alcohol napkin. Update the firmware through Settings → Update of the PO.

⚠️ Warning: If a robot starts making squeaking noises while washing, stop cleaning immediately:

• Air entering the pump (you need to add water).
• Flushing in the supply system (washing is required).
• Faulty water level sensor (refer to the service).

6.Care for the wet cleaning system: how to extend the life of a robot

For Xiaomi to be a robot vacuum cleaner, it is not enough to just turn it on as needed. Wet cleaning requires regular maintenance. Here is a minimum set of procedures:

• 🧼 Weekly: Wash the water tank with warm water and soap. Clean the pump filter (needle or toothpick will help remove plaque); Wash the cleaning cloth in the washing machine (no air conditioning!).
• 🔧 Monthly: Check the tightness of the water tank joints. Clean the humidity sensors on the bottom panel of the robot. Lubricate the moving parts of the cloth attachment with silicone lubrication.
• ⚠️ Every 6 months: Perform a deep cleaning of the water supply system (use a scale removal tool). Check the wear of brushes and rollers - they affect the quality of cleaning.

For self-cleaning models (such as the Xiaomi X10+), add a weekly base wash via the app to the chart, which removes bacteria and scale from the internal tubes, which is especially important if you use tap water.

7. Alternative ways to manage wet cleaning

In addition to the Mi Home app, there are other ways to turn on wash mode, which will be useful if the smartphone is dead or there are problems with connection:

• 📱 Voice commands (for models with support) Alice/Google Assistant: Okay, Google, enable wet cleaning on Xiaomi Note: Pre-set voice assistant in Settings → Voice control.
• 🖥️ Manage through Home Assistant (for advanced users): Integrate the robot through a component xiaomi_miio. Use the service vacuum.send_command parameterized mop_start.

Buttons on the robot body

• Press and hold Spot Clean + Home for 3 seconds.
• On the display will appear the icon of the drop (💧), activation.

It doesn't work on all models!

For models with a display (for example, Xiaomi S7 MaxV) you can enable wet cleaning through the menu on the robot screen:

1. Touch the icon Menu (three lines).
2. Select Cleaning Modes → Wet.
3. Adjust the intensity and press Start.
