Where to pour water into the robot vacuum cleaner Xiaomi: detailed instructions for models with the function of wet cleaning

Xiaomi’s wet-cleaning robot vacuum cleaners have become an integral part of a smart home for many users. They effectively manage dry and wet floor cleaning, saving time and effort. However, the question often arises for beginners: where exactly to pour water into such devices so as not to damage the equipment and achieve maximum results? This procedure seems simple only at first glance – improper refueling can lead to leaks, pump breakdowns or even a vacuum cleaner failure.

In this article, we will discuss in detail where the water tank is located in popular Xiaomi models (for example, Mi Robot Vacuum-Mop 2 Pro, DreameBot D9, Viomi V3 and others), what type of water is best to use, and what critical mistakes users make when first filling up. You will also learn how to properly care for the water supply system to extend the life of the device. If you just purchased a robot vacuum cleaner or are planning to buy it, this guide will help avoid typical problems and make cleaning really effective.

Where is the water tank in the robot vacuum cleaners Xiaomi

In most Xiaomi models with wet cleaning function, the water tank is located on the back of the case, next to the garbage container. It is easy to remove and has transparent walls so that the user can control the liquid level. In some devices (for example, Xiaomi Mi Mop P), the tank is integrated into the main unit and opens with a lid that says WATER TANK or a water drop pictogram.

To find the tank, follow the following steps:

• 🔍 Inspect the back of the vacuum cleaner – usually the tank is highlighted in a different color (more often white or gray) and has a relief surface for easy capture.
• 💧 Look for a water pictogram or an inscription WATER — The manufacturer always labels the liquid container.
• 🔄 If the tank is not removed, check if the locker is blocking it - sometimes you need to press a button or move the lid to the side.

In models with automatic water dosing systems (for example, DreameBot L10 Pro), the tank can be equipped with an electronic level sensor, in which case the current volume of liquid is displayed on the display or in the Mi Home application. If your vacuum cleaner does not recognize the tank, check if it is installed correctly - often the sensors only work when the tank is fully fixed.

How to properly fill the water: step-by-step instructions

The process of filling with water depends on the model of the vacuum cleaner, but the general algorithm is the same for most devices. Here is a universal guide that will suit the Xiaomi Mi Mop, DreameBot and other popular series:

1. Turn the vacuum cleaner off the power supply – remove it from the charging station or turn off the power button if there is one.
2. Remove the water tank: 🔹 Press the lock button (if any) or pull the container over yourself. 🔹 In some models (for example, Viomi). V3) The tank is attached to the magnets - just pull it up.

Open the tank lid.

OPEN

Pour water.

• 💦 Use only pure water (better distilled or boiled).
• 🚫 Don't exceed the mark. MAX — This is usually 200-300 ml, depending on the model.
• Close the lid and make sure it fits tightly - this will prevent leaks.
• Install the tank back before clicking or fixing with magnets.

After refueling, make sure the tank is in place correctly. In electronically controlled models (like the DreameBot L10 Pro), a notification of successful capacity recognition should appear on the screen. If the vacuum cleaner gives an error, try removing and re-installing the tank.

What water to fill a robot vacuum cleaner: recommendations and prohibitions

Not only does the cleanliness of the floors depend on water quality, but the life of the pump and vacuum tubes. Xiaomi recommends distilled or boiled water, which prevents scale and clogging of the system. In extreme cases, filtered water will do, but its hardness should not exceed 3-4 mg-eq / l.

What is absolutely impossible to pour into the tank:

• 🚫 Tap water – contains chlorine, salts and mechanical impurities that settle at the pump.
• 🚫 Cleaning products – even those specialised for robot vacuum cleaners can foam and damage sensors.
• 🚫 Hot water – can deform plastic parts of the tank.
• 🚫 Mineral or carbonated water – salts and carbon dioxide destroy seals.

If you use Xiaomi Mi Mop 2 Pro or similar models with automatic spraying, avoid water with high iron content – this will lead to rusty stains on the floor. To flavor the cleaning, you can add 1-2 drops of special air conditioner for robot vacuum cleaners (for example, from Xiaomi or Dreame), but do not exceed the dosage.

⚠️ Warning: If white stains remain on the floor after cleaning, this is a sign of using hard water.Wash the tank and tubes with vinegar solution (1:10 with water), then rinse with clean water several times.

Water volume for different models: compatibility table

Each Xiaomi robot vacuum cleaner model has its own recommended amount of water for wet cleaning, exceeding the limit can lead to leaks, and a disadvantage can lead to poor washing quality.

Note that in models with adjustable water intensity (for example, DreameBot L10 Pro), the volume can be adjusted in the Mi Home application. For laminate or parquet, it is recommended to reduce the amount of water by 20-30% to avoid swelling of the coating.

💡

If your vacuum cleaner starts to spit with water or leave puddles, check the condition of the sealing gum on the tank. Over time, it wears out and requires replacement (you can order the original part by model number).

Common Mistakes in Water Refilling and How to Avoid Them

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

1. Water overflow – if you exceed the MAX mark, the liquid can get into the electronic components of the vacuum cleaner. In some models (for example, Viomi V3), this leads to an E5 error (sensor leakage).
2. Using a dirty tank – if the container is not washed after each cleaning, mucus and bacteria form inside, which are then sprayed on the floor.
3. Pouring water with connected power – this can cause a short circuit, especially if the liquid gets to the contacts of the charging station.
4. Ignoring sensor errors -- if the vacuum cleaner is reporting a tank malfunction, don't continue cleaning. Most often, the problem is solved by reinstalling the tank.

Another common mistake is to install a napkin incorrectly, and in vibrating mop models like the DreameBot D9, the fabric must fit tightly to the sole, otherwise the water will not be evenly distributed.

• 🧹 The napkin is fixed on Velcro and does not move out.
• 💧 There are no folds that can block the water supply.
• 🧼 Clean fabric – if it is contaminated, the vacuum cleaner will smear the dirt, not remove it.

⚠️ Warning: If the vacuum cleaner starts making unusual sounds after cleaning (such as gurgling or grinding), turn it off immediately and check the tank for air in the system.

How to care for a water tank: tips for cleaning and storage

To make the water tank last longer, it needs to be cleaned regularly and stored properly. Xiaomi's manufacturer recommends following procedures:

1. Washing after each cleaning: 🚰 Rinse the tank with warm water and wipe with a soft sponge. 🧼 For disinfection, use a weak solution of vinegar (1 tbsp. l. per 1 liter of water) 1 time per month.
2. Drying before storage: 🌬️ After washing, leave the tank open for 1-2 hours to evaporate moisture. 🚫 Do not store the vacuum cleaner with water in the tank for longer than 24 hours - this leads to mold.

Checking seals

• 🔍 Check the rubber bands on the tank lid every 3 months. If they've lost their elasticity, replace them.

💡

Use only distilled or boiled water, do not exceed the MAX mark on the tank and regularly wash the container - this will prolong the life of the robot vacuum cleaner and ensure high-quality cleaning.
