Where and how to pour water into the robot vacuum cleaner Xiaomi Vacuum Mop Essential: detailed instructions with nuances

Xiaomi Vacuum Mop Essential has become a popular solution for automating cleaning with a combination of dry and wet cleaning functions. However, new owners often wonder where to pour water in this model so as not to damage the device and maximize the efficiency of floor washing. Unlike classic vacuum cleaners, the water supply system is integrated into the housing, and improper handling of the tank can lead to leaks or breakage of the pump.

In this article, we will discuss the exact location of the water tank, step-by-step instructions for refueling it, and the typical mistakes that users make. We will pay special attention to the nuances of the Essential model - it differs from the flagship versions (for example, Xiaomi S7) in a simplified design, but it requires no less careful handling. If you have just unpacked the device or plan the first wet cleaning - this instruction will help to avoid annoying miscalculations.

Where is the water tank in Xiaomi Vacuum Mop Essential: photos and diagrams

In the Vacuum Mop Essential, the water tank is located on the top of the body, under a removable lid with the Mi logo. Externally, it is a 200 ml translucent plastic container that serves as both a liquid container and a napkin mount, a key difference from older models (for example, the Xiaomi S5 Max), where the tank is made separately.

To find him:

• 🔍 Turn over the robot vacuum cleaner (turn it off before you do it!) And on the bottom of the room you'll see a tissue bay, and that's where the water tank sits above it.
• 📦 Remove the top panel lid (latched by the latches, pull it over with a little effort) and you'll see a white or gray plastic tank underneath that with water level tags.
• 💧 Pay attention to the labels: on the walls of the tank there are risks MIN and MAX — exceeding the upper mark is strictly prohibited!

If you're not sure you've found the right compartment, compare your device to the official photos from the manual (see below). The Essential water tank is not removable, it's rigidly attached to the housing, unlike a garbage container, which is fully removable.

Step-by-step: how to properly pour water

The process of refilling water in Xiaomi Vacuum Mop Essential requires care, as overflowing or getting liquid into electronic components can cause the device to fail.

1. Turn off the robot vacuum cleaner and remove it from the docking station (if it's connected).
2. Remove the top compartment cover by pulling it on you until you click. The top should be removed effortlessly -- if it's jammed, check if the wipe on the bottom is blocking it.
3. Open the water tank: press the lock button (usually located on the right) and lift the tank cover. In some versions of Essential, the lid opens up, in others it shifts sideways.
4. Pour water through the hole, focusing on the MAX tag. Use only pure water (better distilled or boiled) - chlorine or hard water from the tap can clog the pump.
5. Close the tank before you click and make sure the top compartment cover fits tightly. Check if there are any leaks - if water drips from below, then the napkin is installed incorrectly.

Critical nuance: the Essential model can not use detergents or flavors - this will break the pump and void the warranty. If you need disinfection, add 1-2 drops of vinegar (no more!), but only after checking the reaction on an inconspicuous area of the floor.

What water can be poured: requirements and prohibitions

Water quality not only determines the cleanliness of the floors, but also the life of the pump and the tubes of the robot vacuum cleaner.

If you use tap water, regularly wash the tank (every 2 weeks) with a weak solution of citric acid (1 tsp. per 1 liter of water) to remove the scale.

1. Pour the solution into the tank and leave for 10 minutes.
2. Turn on the wet cleaning mode for 1-2 minutes (on a flat surface).
3. Wash the tank with clean water and dry.

⚠️ Warning: If there are white stains on the floor after cleaning, this is a sign of hard water, in which case switch to distilled water or install a water filter in the house.

Common Mistakes in Water Refilling and How to Avoid Them

Even experienced users sometimes make mistakes that lead to leaks or less efficient cleaning, and the most common ones are:

• 🚫 Water overflow above the mark MAX — This leads to leakage through the napkin and possible short circuit. Always check the fluid level when the robot is horizontal.
• 🚫 Using hot water - deforms plastic parts of the tank and damages seals. Water temperature should be room (18-25)°C).
• 🚫 Closing the tank with an incompletely inserted napkin – a napkin can block the water supply or shift during cleaning, leaving dry stripes.
• 🚫 Storing a robot with water in a tank - if the device stays idle for more than a day, the water stagnates, and bacteria can multiply in the tubes!

Another common problem is that the robot doesn't wash the floor, even though there's water in the tank, and the reasons may be:

• 🔧 Clogged pump (you need to flush the system as described above).
• 📱 Not selected wet cleaning mode in the Mi Home app (check the task settings).
• 🧹 Wraps are worn or crooked (replace them with a new one).

How often should you change the water and take care of the tank?

The manufacturer recommends that you drain the water after each cleaning, but in practice, many users ignore this rule.

• 🔄 After each cleaning: drain the remaining water, rinse the tank with running water and dry it in air (do not use a hair dryer!).
• 🧼 Once a week: Wash the tank with a soft sponge and soapy solution (no abrasives!), paying attention to the corners and the feed tube.
• 🔧 Once a month: check the condition of the napkin — if it has become hard or lost absorbent properties, replace it.

If the robot is used rarely (for example, every 2-3 days), it is enough to drain the water and dry the tank every 48 hours.

1. Completely drain the water and dry all the components.
2. Take off the napkin and wash it by hand (no bleach!).
3. Store the robot in a dry place at a temperature of 10–30 ° C.

⚠️ If the house is high humidity (more than 60%), you can not leave water in the tank even for several hours - this will lead to the appearance of mold in the tubes.

💡

To keep the water fresh longer, add 1-2 grains of citric acid (at the tip of the knife) to the tank, which will slow down the growth of bacteria and reduce the smell of stagnant water.

Comparison with other Xiaomi models: what is different Essential

In the line of robot vacuum cleaners Xiaomi wet cleaning system implemented in different ways, compare Vacuum Mop Essential with other popular models:

The main advantage of Essential is its simplicity of design, which makes it easier to care for, but the lack of automatic water dosage means that the user has to manually adjust the intensity of washing through the app, and in older models (such as the S7), this process is automated based on the type of coating (laminate, tile, parquet).

If you're planning an upgrade, look at the removable tank models, which are easier to wash and less likely to leak. For example, in the Xiaomi S6, the tank is removed in one motion, while in Essential, it requires the top cover to be dismantled.

💡

The Vacuum Mop Essential is suitable for small rooms (up to 60 m2) with flat floors. For large apartments or complex coatings (carpets + tiles), it is better to choose a robot with automatic water control (for example, Xiaomi S7).
