Preparing Xiaomi’s robot vacuum cleaner for wet cleaning: the full guide 2026

Why Preparing for Wet Cleaning Is Critical for Xiaomi Robots

Robot vacuum cleaners Xiaomi with the function of wet cleaning is not just gadgets for the lazy, and high-tech devices that require competent handling. Incorrect preparation for wet cleaning can lead to water leakage to electronic components, damage to flooring or even failure of the device, especially for models with a Yiko system (for example, Xiaomi Mijia). 1T or DreameBot. W10), pressure-driven.

In this article, we will look at how to prepare a robot vacuum cleaner Step-by-step for wet cleaning, from checking the configuration to adjusting the modes in the Mi Home app. You will learn how to avoid typical errors (for example, using inappropriate detergents) and prolong the life of the device.

If your robot assistant has been collecting dust in the corner for months and you are afraid to "bath" it - do not worry. V3 Roborock S7 MaxVs are designed with wet cleaning in mind, but only with the rules in mind. Next up, everything you need to know to keep your machines clean and get perfectly clean floors.

Step 1: Check the model for compatibility with wet cleaning

Not all Xiaomi robot vacuum cleaners support wet cleaning, for example, budget models like the Mi Robot Vacuum-Mop 2 Lite can only sweep, but Roborock can only sweep. S7 or DreameBot. L10s Ultras are equipped with full-fledged floor washing systems?

Ways to determine support for wet cleaning:

• 📄 Documentation: Find the "Wet Mopping" or "Wet Cleaning" section in the instructions. If it's not available, there's no function.
• 🛒 Package: The box should have a water tank (often transparent) and a washing wipe (microfibra).
• 📱 In Mi Home or Roborock, check for Mop or Wet Cleaning modes".
• 🔍 Labeling: There may be a water drop icon on the body or tank 💧.

If your model does not support wet cleaning, but you are trying to “adapt” it (for example, attaching a homemade cloth), this can cause engine failure or short circuit.

Step 2: Preparing a water tank – what can and cannot be poured

The water tank is the heart of the wet cleaning system, and the wrong fluid can clog the pipes, damage the pump, or leave the floors in a diluted state.

Liquids allowed:

• 💧 Distilled or boiled water is the best option, does not leave a plaque.
• 🧼 Special cleaning products for robot vacuum cleaners (for example, Xiaomi Mop Detergent).
• 🍃 Vinegar solution (1:10) - only for tank disinfection (not for permanent use!).

Prohibited liquids:

• ❌ Household chemicals (such as Mr. Proper or Cif) – foam and clog the system.
• ❌ Boiling water - deforms plastic and damages seals.
• ❌ Alcohol, acetone, bleach - corroded by hoses and gaskets.

The volume of water depends on the model. S7 300 ml tank and in DreameBot W10 — It's 4 liters (with self-cleaning system) and don't overflow, it'll increase the weight of the robot and reduce maneuverability.

Step 3: Installation and fixing of washing wipes – mistakes that spoil cleaning

A washing wipe (usually made of microfiber) is attached to the bottom of the robot. It would seem that this is difficult?

• 🧹 Poor contact with the sex – there are unwashed areas.
• 💦 Water leaks - if the napkin shifts and exposes the feed holes.
• 🔊 Extraneous noise – if the fabric gets into brushes or wheels.

How to properly install a napkin:

1. Remove the dust collector (if it interferes with access to the mount).
2. Spread the napkin on a flat surface and combine the holes with the mounts on the robot.
3. First, fasten the front, then the back (on some models there are Velcros or latches).
4. Check the tension - the napkin should not sag, but should not be pulled.

For models with a vibration sink (for example, Roborock) S7 MaxV Ultra) a napkin should be special, with reinforced edges. A normal microfiber wears out quickly.

💡

If the wipe starts to absorb water poorly, wash it by hand with household soap (without bleach) and dry it on the battery. Don't use the washing machine - it will damage the microfiber fibers.

Step. 4: Configure wet cleaning modes in the Mi application Home/Roborock

Without the right settings in the app, even a perfectly trained robot can't do the cleaning. Let's look at the key parameters like Mi Home and Roborock:

Main regimes:

In the Roborock application, you can also configure:

• 📏 Water level (low to high).
• 🔄 Number of passages in one place (useful for stained dirt).
• 🚫 Avoidance zones (such as carpets during washing).

For models with hot water (for example, DreameBot) W10) You can choose the heating temperature in the settings, but remember, hot water speeds up the wear of the wipe and increases the energy consumption.

Step 5: Preparing the room – what to remove so as not to spoil the robot

Even the smartest robot vacuum cleaner can't do a cleaning job when the room is in chaos, and the preparation of the room is as important as the setting of the device itself.

Make sure to clean up:

• 🧦 Small objects (socks, toys, wires) – they can get stuck in brushes.
• 🧺 Carpets with a long pile – the robot will “twist” or pour water on them.
• 🪑 Chairs on wheels - they can move and block the way.
• 🐕 Animal bowls – water or food can get into the device.

What can be left:

• 🛋️ Couches and closets – if they are not “adjacent” to the walls.
• 🌿 Houseplants (but lift the pots to height) >10cm).
• 📦 Boxes and drawers, if they do not block the passages.

Pay special attention to the thresholds and transitions between rooms. >1.5 cm, the robot may get stuck, in which case use virtual walls in the app or physical restraints.

💡

Before the first wet cleaning, test run in Dry Run mode (without water) so that the robot remembers the layout and possible obstacles.

Step 6: Care for the robot after wet cleaning – extend the service life

Many users forget that after floor washing, the robot vacuum cleaner needs care, too, and ignoring this stage leads to:

• 🦠 Mold in the tank (if you leave the water for a long time).
• 🔋 Corrosion of contacts (due to moisture residue).
• 🧹 Blockages in the tubes (if not wash the system).

Checklist for care after cleaning:

1. Drink the water from the tank and dry it in the air (not in direct sunlight!).
2. Remove and rinse the napkin under running water, then dry.
3. Wipe the sensors and contacts on the bottom of the robot with a dry cloth.
4. Clean your brushes and wheels of wound hair or thread.
5. Store the robot in a dry place with the tank cover open (for ventilation).

For models with self-cleaning systems (e.g. DreameBot) L10s Ultra) after cleaning, run the Cleaning Station cycle to flush the hoses and tank. Use special cleaning tablets (e.g. Xiaomi Cleaning Tablets) 1 time per month.

💡

If the robot begins to smell bad, pour vinegar solution (1 tbsp. l. per 1 liter of water), turn on the wash mode for 5 minutes, then rinse the system with clean water.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when cleaning wet. TOP-5 Failures and how not to repeat them:

1. Use of non-original wipes

⚠️ Attention: Cheap wipes from AliExpress are often incorrectly dense and sized, causing water to leak or not soak up, leading to puddles on the floor and overheating of the pump.

Solution: Buy wipes with labels compatible with your model (e.g. for Roborock) S7 Only napkins with code will do. RR-S7-MOP).

2 Forgetting to clean sensors

Dust and water spray on sensors (especially on the LDS-Lidars lead to navigational errors, and the robot begins to "lose," skip zones, or collide with furniture.

Solution: wipe the sensors with a dry lilaless wipe after each cleaning.

3. Cleaning on long-pile carpets

⚠️ Warning: Wet carpets are the perfect medium for mold, and the robot can also drown in the pile, and water can get into the engine.

Solution: In the application settings, add carpets to No-Mop Zones or use virtual barriers.

4. Storing a robot with water in a tank

If you leave the water for a long time, bacteria multiply in the tubes, and the seals lose their elasticity, which leads to leaks and unpleasant odor.

Solution: Always drain the water after cleaning and dry the tank.

5. Ignoring firmware updates

Manufacturers regularly release updates that improve the wash algorithms. S7 After updating to version 3.5.8, the Auto Lift Mop function appeared - lifting the napkin on the carpets.

Solution: Check the updates in the app once a month.
