How to properly pour water into the washing robot vacuum cleaner Xiaomi: instructions with photos and nuances

Xiaomi’s cleaning robot vacuum cleaners (including Mi Robot, Dreame and Viomi models) require a special approach to water refilling – errors here can lead to leaks, pump breakdowns or inefficient cleaning. Unlike conventional vacuum cleaners, where it is easy to fill the tank, cleaning versions are important to consider the type of tank, cleaning mode and even water quality. For example, hard tap water can clog the nozzles after 2-3 months of intensive use.

In this article, we will analyze not only the basic instructions for pouring water, but also hidden settings in the Mi Home application that affect fluid flow, as well as typical errors due to which the robot leaves divorces or stops spraying water. Particular attention will be paid to models with electronic level control (for example, Xiaomi Mi Robot Mop 2 Pro or DreameBot). L10 Pro) where improper refueling can cause sensors to fail.

1. Preparation of the robot vacuum cleaner for pouring water: what to check before refueling

Before you pour water, make sure your Xiaomi robot vacuum cleaner is ready for wet cleaning.Missing these steps can lead to leaks or damage to electronic components.

• 🔋 Battery Charging: The charge level must be at least 20%. Otherwise, the robot can interrupt cleaning and leave puddles on the floor.
• 🧹 Cleaning the main dust collector: If the garbage container is full, the robot will not be able to effectively suck up dirt after spraying the water. Remove and rinse it under running water (except models with running water). HEPA-filter - it can only be vacuumed).
• 🔄 Napkin/nozzle check: Make sure the washing module (a rag or microfibre nozzle) is tightly secured and has no tears. V3 and DreameBot D9 the squirrel should be clicked when installing.
• 💧 Water type: Use only distilled or filtered water. Tap water with high salt and chlorine clogs the nozzles and shortens the life of the pump.

If you use a detergent (e.g. a special solution for robot vacuum cleaners), add it to the water after pouring, not before. Concentrated products can damage the tank sealing gums. Optimal proportion: 1 cap of the remedy per 500 ml of water.

⚠️ Note: Xiaomi Mi Robot Mop P and DreameBot W10 You can't use products that contain bleach or abrasive particles, and this will corrosion the metal parts of the pump.

Step-by-step instructions: how to pour water into the tank (with photos and videos)

The water refill process depends on the robot vacuum model. Below is a universal algorithm that works for most Xiaomi, Dreame, and Viomi devices. For an accurate instruction, check your model's user manual.

Step 1: Removing the water tank

1. Turn off the robot vacuum cleaner (Power button or via the Mi Home app).

2. Turn the device over and find a water tank – it is usually located next to the dust collector and marked in blue or blue.

3.Push the lock (in DreameBot models it is the Release button) and gently remove the tank.

Step 2: Pouring water

1. Open the tank cover (in some models it turns counterclockwise).

2.Pour water to the mark MAX (In models with an electronic sensor (e.g. DreameBot) L10 Pro) exceeding the level will lead to an error E5.

3. Close the lid before you click. Make sure the sealing gum is not twisted.

Step 3: Install the tank back

1.Put the tank in the grooves before the characteristic click.In Viomi models V3 horn.

2 Turn the robot over and make sure the tank is not wobbling. If the tank is installed incorrectly, the robot won't start cleaning.

3. Features of refueling in different models Xiaomi

Not all Xiaomi robot vacuum cleaners are refueled the same way. The table below shows the key differences for popular models. Pay attention to the volume of the tank and the type of spraying, which affects the frequency of water topping.

In models with ultrasonic spraying (for example, DreameBot) L10 Pro) water must be at room temperature. Hot water (over 50)°C) may damage the spray membrane. For mechanically sprayed robots (e.g. Viomi) V2) water temperature is not critical, but it is better to avoid ice liquid - this increases the load on the pump.

4.Typical water pouring errors and how to avoid them

Even experienced users sometimes make mistakes that lead to leaks or poor cleaning quality, and here are the most common ones and ways to prevent them:

• 🚫 Tap water use: Salt and chlorine are deposited on the nozzles, reducing spraying efficiency. After 3-6 months, a pump replacement may be required (cost) ~1500–2500 rubles.).
• 🚫 Water pouring with the robot on: In electronically controlled models (e.g. DreameBot) L10) This can cause sensors to fail. Always turn off the device before refueling.
• 🚫 Ignoring errors in the app: If Mi Home shows a low water level warning (Error) E2), Do not continue cleaning - this will lead to the work of the pump idle and its overheating.
• 🚫 Mixing different detergents: A chemical reaction can clog the tubes or cause foaming, leading to leaks.

Another common problem is the uneven spraying of water. If the robot leaves dry stripes, check:

1. Clean the nozzles (clean with a needle or compressed air).
2. Water level in the tank (at a low level, the pump does not create enough pressure).
3. In-app settings: In Mi Home, select Deep Mopping mode for intense spraying.

💡

If the robot starts spitting water or leaving puddles, check the tank's sealing gum, it loses elasticity over time, and grease it with silicone lubricant (e.g., grease it with silicone, WD-40 Specialist) to restore leakage.

5 How often should water be refilled and when to change it completely

The frequency of water topping depends on the cleaning area, the spraying mode and the robot model.

• 📏 Up to 50 m2: water is enough for 1 cleaning (no more is required).
• 📏 50–100 m2: Add water after the first half of cleaning (the robot will pause and signal).
• 📏 Over 100 m2: it is recommended to divide the cleaning into zones or use a robot with a large tank (for example, DreameBot). L10 Pro at 300ml).

Complete water replacement should be carried out:

• ⏳ After each cleaning (if the detergent was used).
• ⏳ 3-5 times a day (if only water was used).
• ⏳ Immediately, if the water becomes cloudy or an unpleasant odor appears (a sign of bacterial reproduction).

To extend the life of the pump and tank, follow these tips:

• 🧼 Once a month, wash the tank with a weak solution of vinegar (1 tbsp. spoon per 1 liter of water) to remove scale.
• 🌡️ Store the robot in a dry place at a temperature of 10–30°C. Condensation inside the tank may cause corrosion.
• 🔄 If the robot is not used for more than 2 weeks, drain the water and dry the tank.

⚠️ Note: In tank self-cleaning models (e.g. DreameBot) W10) You can't leave the water inside for more than 24 hours, and automatic flushing doesn't remove all the bacteria, and the water starts to bloom".

💡

Use distilled water or water after reverse osmosis – this will increase the life of the pump by 30-50% and prevent nozzles from clogging.

6. water spraying settings in the Mi Home app

In appendix Mi Home (or Dreame/Viomi And for the right brands, you can fine-tune the spraying intensity, and this is especially useful for different coatings:

• 🌊 Mode "Light cleaning" (Low): 0.5-1 ml of water per 1 m2. Suitable for laminate and parquet.
• 🌊 Standard mode (Medium): 1.5-2 ml / m2. Optimal for tile and linoleum.
• 🌊 Deep cleaning mode (High): 3-4 ml/m2 Only for water-resistant coatings (e.g. porcelain porcelain).
• 🌊 Zone cleaning mode (Custom): allows you to set different intensity for different rooms.

To change the settings:

1. Open the Mi Home app and select your robot vacuum cleaner.
2. Go to Settings. → Cleaning regimes → Water settings.
3. Select the desired mode or set up custom zones on the map.
4. Save the changes and start cleaning.

In laser scanned models (e.g. DreameBot) L10 Pro) you can create "virtual walls" for areas where water spraying is not necessary (e.g. carpets:

1. In the app, go to the Map → Edit.
2. Click Add Zone and circle the area where water is not required.
3. Select the option to prohibit wet cleaning.

7 What to do if the robot does not spray water

If Xiaomi's robot vacuum cleaner has stopped spraying water, the reasons could be both software and hardware.

• 🔍 Check the water level: Even if the tank is full, the sensor could break. Try to add 20 to 30 ml of water - sometimes it resets the error.
• 🔍 Clean the nozzles: Remove the tank and clean the sprayer holes with a toothpick or compressed air. In Viomi models, the nozzles can be washed under a stream of warm water.
• 🔍 Reboot the robot: Hold the Power button for 10 seconds, then turn it on again.This will reset sensor errors.
• 🔍 Check the settings in the app: Make sure you select a water spray mode (not just dry cleaning).

If the problem is not solved, perform a diagnosis:

In DreameBot models with ultrasonic spraying (L10 Pro, D9) A common problem is membrane detachment, and if you hear a high-frequency squeak while you're working, but the water isn't sprayed, you need to replace the membrane. ~800-1200 rubles, the replacement takes 10-15 minutes.

8.Alternative refueling methods: when the standard method is not suitable

In some situations, it is impossible or inconvenient to pour water through a standard tank.

• 💧 Use of an external tank: In DreameBot models W10 viomi V3 You can connect an external water tank (sold separately) and it's convenient for cleaning large areas (over 150 m²).
• 💧 Manual pouring through the tube: If the tank cover is broken, you can gently pour water through the silicone tube (company with some models). MAX.
• 💧 Refilling through drainage hole: In emergency cases (such as if the lid does not open), it is possible to pour water through the drainage hole under the tank, but this requires skill so as not to spill liquid on the board.

For self-cleaning models (e.g. DreameBot) W10) You can use an automatic refueling system:

1. Connect the robot to the self-cleaning station (includes).
2. Pour water into the main tank of the station (capacity) ~4l).
3. In the app, select the option of gas station.
4. The robot will self-supply water during cleaning.

This method is suitable for homes with a large area (over 200 m2) or if you often forget to add water by hand.
