How to pour water into the robot vacuum cleaner Xiaomi: instructions with photos and tips

Xiaomi’s wet cleaning robots are real home assistants, but their effectiveness depends on proper use. One of the most common mistakes users make is incorrect watering, which leads to leaks, pump breakdowns or poor quality washing. In this article, we will discuss how to pour water into the tank of different models (Mi Robot Mop 2 Pro, Dreame Bot). W10, Viomi V3 etc.), what liquids can be used, and also give tips on the care of the water supply system.

It is important to understand that the refueling process differs depending on the type of tank: some models have a tank combined with a dust collector, others have a separate water container. We will consider both options in detail, and also tell you why you can not use ordinary tap water without filtration - this reduces the life of the pump on the water. 30-40%. If you just bought a robot vacuum cleaner or faced problems when washing the floors, this guide will help you avoid typical mistakes.

Preparing a robot vacuum cleaner for pouring water

There are several steps that must be taken before you pour the water, and neglecting them can cause malfunctions or even the detergent module to fail.

First, make sure the robot is turned off. Although most Xiaomi models have open-tank protection, there is still a risk of short-circuit if moisture hits the contacts.

• 🔋 Battery level - if it's below 20%, it's better to recharge the device first. L10 Pro) block the washing function at low charge.
• 🧹 Cleanliness of the main dust collector – if it is full, the robot may misallocate weight and leave divorces.
• 🔧 The condition of the detergent module - on a napkin or brush should not be dried dirt or pile.

Pay special attention to the sealing gums on the tank lid. If they are contaminated or damaged, water will leak during cleaning. Wash them with a dry cloth before each refueling. For models with electronic water flow control (Xiaomi Mi Mop). 2T) It is also recommended to reset errors in the Mi Home app before cleaning up.

What water can be poured into a robot vacuum cleaner

Water quality is not only responsible for the cleanliness of the floors, but also for the durability of pumps, tubes and injectors. Xiaomi officially recommends distilled or filtered water, but other options are also in practice, such as avoiding high-salt hard water.

Here's what you can and can't pour:

• ✅ Distilled water is ideal, does not leave a plaque on the details.
• ✅ Boiled water - suitable for periodic use, but can form scale over time.
• ✅ Filtered water (via household reverse osmosis filter) – the optimal balance between quality and availability.
• ❌ Tap water – contains chlorine, salts and mechanical impurities that clog the system.
• ❌ Mineral or carbonated water – salts and carbon dioxide destroy seals.
• ❌ Soap solutions or detergents – only if they are certified for robot vacuum cleaners (e.g. Xiaomi Floor Cleaner).

For models with automatic dosage of detergent (Dreame Bot) W10) You can use special capsules, but not ordinary floor washing fluids. They foam and can incapacitate the pump. If you want to add a flavor, use only water-based products without alcohol.

💡

To test the hardness of the water at home, drop a few drops on the black surface and let it dry. If there is white plaque left, the water is too hard for a robot vacuum cleaner.

Step-by-step: how to pour water into the tank

The refueling process depends on the design of your model, below is a universal instruction that is suitable for most Xiaomi robot vacuum cleaners, as well as features for the popular series.

1. Removal of the tank

Open the top cover of the robot (usually with a latch or a magnet). In MiJia models, the water tank is on the right, in Dreame, in the center. Pull the container up carefully without undue effort. If the tank is not removed,

• 🔹 Check if it is locked with the fixing button (available in Viomi) V3).
• 🔹 Make sure the robot is off – some models lock the tank when operating.
• 🔹 Check the guides for contaminants (wipe them with a cotton swab).

2. Water pouring

Remove the lid from the tank (usually it unscrews counterclockwise or opens at the latches). MAX, In models with a double tank (for example, Dreame Bot). L10 Pro) have separate compartments for clean and dirty water - don't confuse them!

For convenience, you can use:

• 💧 Lake with narrow nose (combined with some models).
• 🧃 Bottle with dispenser - it is easier to control the level.
• 📏 Measured glass (volume of tank specified in the instructions, usually 200-300 millimeter).

3. Installation of the tank back

Before you put the tank in place, check:

• 🔸 The sealing gums are clean and in place.
• 🔸 The tank cover is twisted to click (in Xiaomi Mi Mop P models there is an indicator of correct closing).
• 🔸 There are no drops of water on the tank outside - wipe it with a dry cloth.

Install the tank before the characteristic click. In models with an electronic sensor (Dreame Bot). W10) On the screen will be a confirmation of the successful installation.

💡

Never pour water into a robot vacuum cleaner if it is in a charging station, which can lead to short circuits due to condensation on the contacts.

Features of refueling for popular models

While the principle of water pouring in all Xiaomi robot vacuum cleaners is similar, there are nuances for specific series.

For models with a self-cleaning wipe (Dreame Bot) L10 Pro, after pouring the water, you need to start the process of washing the tank through the application, which will remove the residue of detergent and prevent mold formation. 1C) Wash the napkin manually after each cleaning.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when refilling water that lead to breakdowns or poor cleaning quality.

⚠️ Warning: If there are wet marks or stains on the floor after cleaning, you've probably transfused water.In models without a level sensor (Viomi) V2) Maximum volume – 200 ml, even if the tank holds more.

• 🚫 Hot water use causes plastic parts to deform and leaks. Optimal temperature — 15-25°C.
• 🚫 Pouring water into the robot on – risk of short circuit, especially in models with electronic pump control.
• 🚫 Ignoring tank cleaning – if you do not wash the tank after each cleaning, mucus and mold form inside.
• 🚫 Mixing water with uncertified detergents – this voids the warranty and can disable the pump.

Another common problem is that the robot doesn't spray water during cleaning, and the reasons may be:

• 🔧 Clogged nozzles (clean them with a toothpick).
• 🔋 Battery is dead (some models turn off the pump when charged below 30%).
• 💧 Less than 50 ml of water is left in the tank (the sensor does not work).
• 📱 Not selected the function of washing floors in the application (check the settings of the cleaning area).

If the robot starts to make unusual sounds (squeaking, humming) when spraying water, immediately stop cleaning and check the pump for foreign objects. 80% of the time the cause is the pile or hair getting into the mechanism.

How to take care of the water supply system

For a robot to last, it's not enough to just pour water right -- you need to regularly service all the components that come into contact with the fluid. Here's a monthly maintenance checklist:

• 🧼 Wash the tank once a week with a mild detergent (such as Baby Line), then rinse with clean water.
• 🧹 Clean nozzles – clean the sprayer holes with a toothpick or compressed air (a canister for cleaning the technique).
• 🔄 Replace the sealing gums every 6 months, even if they look whole. Over time, the rubber loses its elasticity.
• 🔋 Checking the contacts of the pump - with corrosion (white plaque), clean them with a cotton swab dipped in vinegar.

For models with self-cleaning napkins (Dreame Bot) W10) Once a month, run the deep cleaning function through the app, which removes the scale and residues of detergent from the tubes. If your robot does not support self-cleaning, soak the removable parts (cloth wipe, filter) in a solution of citric acid (1 tbsp. per 1 liter of water) for 30 minutes.

⚠️ Warning: Never use abrasives or hard brushes to clean the tank – they scratch the plastic, and bacteria multiply in microcracks over time.

If you live in a very hard water area, pour vinegar solution (1:1 with water) into the tank every 3 months and turn on the wash mode for 5 minutes, then rinse the system with clean water, which will help remove lime plaque from the inner surfaces.

What to do if water leaks from a robot vacuum cleaner

Leaks are one of the most common problems in the operation of cleaning robot vacuum cleaners. If you notice puddles under the device or wet marks on the floor outside the cleaning area, proceed with the following algorithm:

1. Turn off the robot immediately and remove the water tank.
2. Check the integrity of sealing rubber bands – if they are torn or deformed, replace them.
3. Examine the tank body for cracks (especially in places of attachment to the robot).
4. Make sure that the tank cover is twisted to the point – Xiaomi Mi Mop models have an indicator of correct closing (green label).
5. Check the condition of the tubes and connections – sometimes they jump when the robot falls.

If leakage occurs during cleaning, the cause may lie in:

• 💦 Overflow water – drain the excess and repeat cleaning.
• 🔧 Clogged valve water supply - disassemble the tank and clean it.
• 📉 Pump malfunctions - diagnostics are required in the service center.

For a temporary solution, you can reduce the intensity of the water supply in the application settings (Water Volume or Wet Washing). Dreame models also have a Superabsorbent wipe feature that reduces the risk of leaks.

💡

If a robot vacuum cleaner falls from a height (such as a table), even without visible damage, check the tightness of the water supply system.
