Where to pour water into the robot vacuum cleaner Xiaomi Vacuum Mop: detailed instructions with a photo

Xiaomi Vacuum Mop has become an indispensable tool for thousands of users, combining dry and wet cleaning functions. However, even experienced owners of smart equipment sometimes face a simple but important question: where exactly to pour water to make the device work efficiently and without breakdowns. Misfiling when filling a water tank can lead to leaks, damage to electronic components or uneven moisture of the floor.

In this article, we will not only show the exact location of the water hole in different models of the Vacuum Mop series (including the popular Mi Robot Vacuum-Mop). 2C/2Pro/2Ultra), But we also look at the fluid selection rules, the frequency of fluid replacement, and the common mistakes that shorten the life of the equipment. 2023–2026 years not mentioned in the official instructions.

Where is the water hole: a visual guide

In most Xiaomi Vacuum Mop models, the water tank is located on the back of the case, under a removable lid.

1. Place the robot vacuum cleaner on a flat surface and turn it off (the power button is usually on the top panel).
2. Inspect the back of the device – look for a rectangular or oval cap with a water drop pictogram.
3. Press the cap locker (in models) 2Pro And newer, it's often hidden under a rubber plug, and remove it by moving upwards.

Under the cover you will see two compartments:

• 💧 Water tank - transparent or white tank with blue/green cover (volume 200-300 ml).
• 🧹 Dust container – black or gray compartment with filter (not to be confused!).

Xiaomi Vacuum-Mop models 2Ultra and DreameBot W10 (The system is more complex: there is an additional pump for automatic water supply, in which case the pouring hole is hidden under the folding panel on the top of the case (near the switch on button).

Step-by-step: how to properly pour water

The process of filling the tank seems simple, but there are nuances that affect the quality of cleaning.

Disconnect the device from the charging station

Remove the water tank lid

Check the cleanliness of the filter in the dust collector

Use only distilled or boiled water-->

Step 1: Choosing a liquid: The manufacturer recommends pouring only pure water without impurities.

• 💦 Distilled water – prevents the formation of scale in the pump.
• 🚰 Boiled water (cooled) – suitable for short-term use.
• ❌ Prohibited: tap water (due to chlorine), detergents, vinegar or flavorings.

Step 2. Fill the tank. Open the tank lid and slowly pour the water to the mark. MAX (This is usually 200-250 ml in models with automatic dosing (e.g., in the case of a dosing system, 2Ultra) It is enough to fill the tank by 80% - the robot will calculate the required amount.

⚠️ Note: If you use Xiaomi Vacuum-Mop P (2022), do not pour water above 180 ml - this model does not have a transfusion sensor, and excess liquid can damage the electronic unit.

Step 3. Install the napkin. Before starting the cleaning, check:

• 🧼 Wet cleaning wipe is tightly attached to the bottom of the robot.
• 🔄 The fabric has no tears and is wetted evenly during the test run.

💡

If the robot leaves a squash on the floor, add 1-2 drops of a special floor washing tool (for example, Xiaomi Mi Floor Detergent). But do not exceed the dosage - the foam can clog the pump!

Frequent Mistakes and How to Avoid Them

Even small miscalculations in water can lead to serious problems. TOP-5 User errors and their consequences:

The mistake of pouring water into the dust collector is especially dangerous, causing the turbine to break down and requiring expensive repairs.

• 💧 Water tank - transparent, with a blue lid and mark WATER.
• 🧹 Dust collector - black, with a filter HEPA lettering DUST.

⚠️ Note: In Xiaomi Vacuum-Mop models T8+ and S7 The water tank is integrated with the dust collector, and the filler hole is hidden under a turn plug, and you have to turn it counterclockwise to open it.

How often to change the water and clean the tank

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

• 🔄 Water replacement: after each cleaning (or every 24 hours if the robot is used daily).
• 🧽 Washing the tank: every 3-5 days using a soft brush and soap solution.
• 🧴 Disinfection: once a month – pour vinegar solution (1:10) into the tank for 10 minutes, then rinse.
• 🔧 Pump inspection: every 6 months (with signs of weak water supply).

If you use the robot less than 2 times a week, always drain the water after cleaning! stagnant liquid becomes a breeding ground for bacteria, and in models with electronically controlled water supply (for example, 2Ultra) It can cause corrosion of contacts.

For models with self-cleaning wipes (for example, DreameBot) W10) harden:

• 🚿 Water tank and container for dirty water should be rinsed after each cleaning cycle.
• 🔋 Once a week, run the Deep Clean feature with clean water.

Comparison of models: where the filler hole in different versions

The design of the water tank varies depending on the model and year of production, and below is a comparison table for popular devices:

In 2026 models (for example, Xiaomi Vacuum-Mop 3), the manufacturer has implemented a contactless pouring system – water can be added without opening the lid, through a special connector.

💡

In Xiaomi robot vacuum cleaners, never pour water into the dust bay, it will break the turbine and void the warranty. Always check the icons on the tank covers!

What to do if the robot does not spray water

If after pouring water, the robot vacuum cleaner does not wet the napkin or spray the liquid unevenly, the reasons may be as follows:

• 🚫 The pump is clogged, most often because of scale or dust, solution: rinse the system with citric acid (1 tsp per 200 ml of water).
• 🔋 So, with a low charge, the robot shuts off the water supply. Solution: charge to 100%.
• 📱 Firmware failure - in models with electronic control (for example, 2Ultra). Solution: Reset your settings via the Mi Home app.
• 💧 Installation of the napkin wrong -- the sensors don't detect the contact. Solution: Reset the tissue, make sure it's flat.

For diagnostics in models with LDS-laser (e.g., Vacuum-Mop) 2Pro) run the test:

1. Go to the Mi Home app.
2. Choose your robot. → Settings → Diagnostics → spray-test.
3. If the water is not coming in, the system will show an error code (e.g., the error code, E12 — pump-cloth).

⚠️ Note: In the robots Xiaomi Vacuum-Mop S7 and T8+ misstep E15 (Water leakage, you can't continue cleaning, it can short circuit, turn off the device immediately and dry it for 24 hours.

Alternative liquids: what can be added to water

Although the manufacturer insists on using only pure water, some users are experimenting with additives. 2Pro and 2Ultra):

• 🌿 Special tools: Xiaomi Mi Floor Detergent - up to 5 ml per 200 ml of water. Dreame Floor Cleaner - up to 3 ml (for models with self-cleaning).
• 🍋 Natural supplements (once a month): Lemon juice (1 tsp. per 1 liter of water) - to remove scale. Vinegar (1:10) - to disinfect the tank.

It is strictly prohibited:

• ❌ Household chemicals (for example, Mr. Proper) – the foam will clog the pump.
• ❌ Bleachers - corroding rubber seals.
• ❌ Essential oils – leave a greasy film on sensors.

If you use flavoured wipes (such as those with eucalyptus), only pour water – additional additives may react with impregnation of the fabric.
