How to effectively wash the floors with a robot vacuum cleaner Xiaomi: from preparation to care

Xiaomi vacuum cleaners are no longer just gadgets for the lazy — they have become indispensable tools for keeping clean. But if dry cleaning is more or less clear, then wet cleaning raises a lot of questions: How to set up the wash mode? What water to use? Why are there divorces after cleaning? And most importantly, how not to spoil the flooring or the machine itself?

In this article, we will discuss all the nuances of wet cleaning by Xiaomi robots (including Mi Robot Vacuum-Mop models). 2 Pro, DreameBot W10, Viomi V3 You'll learn how to prepare a room, what detergents are safe, how to care for tanks and brushes, and what to do if the robot starts painting dirty stripes instead of cleanliness. Home/Xiaomi Home - They're the ones on 70% determine the quality of the wash.

1.What Xiaomi models support wet cleaning?

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

• 🤖 Mi Robot Vacuum-Mop (all versions including 2 Lite, 2 Pro, 2 Ultra) are the most popular models with basic and advanced washing modes.
• 🌊 DreameBot (series) W10, D9, L10) — flagship devices with Deep Mopping (deep wash) and automatic water change.
• 🧹 Viomi (models) V2, V3, SE) — Budget options with a simple wet cleaning system.
• 💧 Xiaomi Mijia (for example, 1C, 1T) — Hybrid models with a small water tank.

If your model is not on this list, it is likely only for dry cleaning. Attempting to make a homemade “upgrade” (for example, attaching a wet cloth to a regular vacuum cleaner) will lead to sensors breaking or short circuit!

To find out exactly if your robot supports wet cleaning, check:

1. A separate water tank (usually white or transparent)
2. Button or mode Mop/Wet Cleaning in the Mi Home app.
3. Inscription 2-in-1 Vacuum & Mop on the box/in the specifications.

2 Preparation of the room before wet cleaning

Even the smartest robot can't clean a room if it's not prepared, and the main problem is that the stains that get eaten into the coatings -- like coffee, juice, shoe trail -- will just smear them on the floor, making them worse.

Pay particular attention to:

• 🧲 Carpet: Robots can get stuck or spoil the pile. Models with Carpet Detection (e.g. DreameBot) W10) They automatically lift the rag on the carpets, but it is better to remove them.
• 🔌 Electrical appliances: if the floor are chargers or extension cords, the robot can pour them with water.
• 🐾 Liquids: puddles (for example, after washing windows) robot will spread all over the floor.

Also check the type of coverage:

⚠️ Warning: If you have a warm floor, turn it off 2-3 hours before cleaning.A sharp temperature drop can damage the coating when in contact with cold water.

3. Setting up wash mode in the Mi Home app

Most Xiaomi robots are controlled through the Mi Home app (or Xiaomi Home for new models), and the right settings determine how clean the floor will be and how long the equipment will last.

The main parameters that need to be configured:

• 💧 Water level: Low for laminate and sensitive coatings. Medium is a universal mode for tile and linoleum. High for severe contaminants (rarely used!).
• 🧽 Wash intensity: Standard is a regular cleaning. Deep is a lot of friction (for stable coatings only). Y-shaped is a "Y" trajectory for better dirt removal (available on DreameBot).
• 🔄 Number of passages: 2-3 passages can be installed for highly contaminated areas.

How to set up (for example, Mi Robot Vacuum-Mop 2 Pro):

1. Open the Mi Home app → select your robot.
2. Go to Settings → Cleaning Modes → Wet cleaning.
3. Choose the water level and intensity.
4. In the Zone section, mark the areas where you need a wash (you can exclude carpets).
5. Save the settings and start cleaning.

For models with automatic water change (e.g. DreameBot) L10 Ultra) further adjust:

• 🔄 Frequency of rinsing (recommended every 5-10 minutes).
• 🧼 Dosage of detergent (do not exceed 1-2 caps per 1 liter of water).

⚠️ Warning: If the app does not have a separate Mop mode, your model does not support wet cleaning. Do not try to pour water into the dust collector, this will lead to a breakdown!

4.What water and detergents should I use?

One of the most common questions is, can you put ordinary tap water in the robot? Answer: it's possible, but it's not desirable. Tap water contains impurities that will eventually clog the tubes and the tank.

• 💧 Distilled water is ideal, but expensive to use regularly.
• 🚰 Filtered water – This is fine if you have a good filter (e.g. reverse osmosis).
• 🌡️ Boiled water - a budget alternative, removes some salts.

The water temperature should be room temperature (15-25).°C) Hot water may:

• Damage the plastic parts of the tank.
• Destroy the coating (for example, laminate or linoleum).
• Lead to the formation of condensation inside the robot.

The rules on detergents are even stricter:

💡

To remove persistent stains (such as coffee or wine), pre-wipe them manually with a wet wipe with neutral detergent. The robot will finish cleaning the residues without smearing the dirt.

If you use a branded product (for example, Xiaomi Floor Cleaner), follow the instructions on the package. For homemade solutions, stick to the proportion: 1 cap of the product per 1 liter of water.

5. Step-by-step instruction: how to wash the floors with a Xiaomi robot

Now, let's get to the process. Follow this instruction to avoid mistakes.

Charging the battery ≥ 50%|Cleaning of the main brush and side rollers|Wear checks on the rags|Filling the tank with water (not above the mark) MAX)|Installation of a clean wipe (if used reusable)

-->

Step 1: Installation of a cloth/napkin

• For disposable wipes: fasten it to the bottom panel of the robot (usually there are Velcros or clamps).
• For reusable: Wash thoroughly after the last cleaning and make sure it is completely dry.

Step 2. Filling the tank

• Remove the water tank (usually located on the back or top).
• Pour water to the mark MAX (don't overflow!).
• Add a detergent (if necessary) and mix gently.

Step 3: Start cleaning

• Put the robot in the charging station.
• In the app, select Mop or Vacuum & Mop.
• Set up cleaning areas (exclude carpets and furniture).
• Press Start.

Step 4: Controlling the process

• For the first 5-10 minutes, watch the robot move. If it stalls on the stain, stop cleaning and remove the contamination manually.
• Check to see if there are wet footprints behind the robot (which means too much water).

Step 5: Completion of cleaning

• When it's done, the robot will return to base, wait until it's completely stopped.
• Dump the remaining water from the tank.
• Remove the rag and wash it under running water (if reusable).
• Wipe the robot’s sensors and contacts with a dry wipe.

💡

Never leave water in the tank for long! If the robot is idle for more than 2-3 days, drain the liquid and dry the container, which will prevent mold and corrosion.

Typical problems and their solution

Even if you set it up properly, it can work imperfectly, and we'll look at some of the most common problems and how to fix them.

Problem 1: After cleaning, divorces remain.

• 🔹 Reason: Too much water or a dirty cloth.
• 🔧 Solution: Reduce the water level in the settings. Use distilled water. Change/wash the rag more often.

Problem 2: The robot doesn’t wash the floor, it just drives.

• 🔹 Cause: clogged water nozzles or faulty pump.
• 🔧 Solution: Rinse the tank and the tubes under running water, check if the cloth is properly installed (it should fit tightly), if the problem persists, contact the service (possibly broken pump).

Problem 3: Robot leaves dirty stripes

• 🔹 Reason: The cloth is too dirty or the water in the tank is cloudy.
• 🔧 Solution: Change the water after each cleaning. Use two rags: one for wet cleaning, one for final wiping. Add some vinegar (1 tbsp per 1 liter) to the water for disinfection (only for models that support acidic products!).

Problem 4: The robot is not returning to base

• 🔹 Reason: Battery is drained or sensors are contaminated.
• 🔧 Solution: Wipe the sensors (especially infrared ones) with a dry wipe. Make sure there are no obstacles around the base (at least 1 m of free space). Charge the robot manually and repeat cleaning.

Problem 5: Heavy noise during washing

• 🔹 Reason: the tank got garbage or the pump is working for wear.
• 🔧 Solution: Rinse the tank and check for foreign objects. If the noise is still there, reduce the water level or contact the service.

⚠️ Warning: If the robot starts making squeaking noises while washing, stop cleaning immediately! This may indicate that the pump is overheated or short-circuited.

7.Care for the robot after wet cleaning

To make the robot last long, after each floor wash, you need to perform maintenance, which will take no more than 5-10 minutes, but save money on repairs.

What to do after cleaning:

1. Water tank cleaning: Pour out the water residues. Rinse the container with warm water with a mild detergent. Dry in the air (do not use a hair dryer or battery!).
2. Care for a cloth: Disposable - throw away. Reusable - wash by hand (no bleach!) and dry.
3. Brush and wheel cleaning: Remove the wound hair and debris from the main and side brushes. Wipe the wheels with a wet wipe (they often collect dirt).

Sensor check:

• Wipe optical and infrared sensors with a dry microfiber.
• Make sure there is no dust on the lidar (top sensor).

What to do once a month:

• 🧼 Deep cleaning: disassemble the robot (according to the instructions) and wash all removable parts.
• 🔧 Pump inspection: if water is supplied weakly, clean the nozzles with a toothpick.
• 🔋 Battery calibration: discharge the robot to 0% and charge to 100% (prolongs battery life).

What can't be done:

• ❌ Wash the robot under running water (only wet cleaning with a napkin!).
• ❌ Use abrasives to clean plastic.
• ❌ Dry parts with a hair dryer or on a battery (temperature drop will damage plastic).

💡

Regular care increases the life of the robot by 30-50%, especially for models with automatic washing (for example, DreameBot). L10 Ultra, where the pump and tubes clog faster.
