Where to pour water into the vacuum cleaner Xiaomi: instructions for all models with aquafilter

You bought a Xiaomi wet vacuum cleaner, but you're not sure where to pour water to avoid breaking the device? This problem is familiar to many beginners - the manufacturer often misses details in instructions, and improper handling of tanks can lead to leaks or engine failure. In this article, we will analyze all models of Xiaomi vacuum cleaners with aquafilter (including Dreame, Mi Robot and Deerma), show the exact places for pouring water, explain how much liquid is safe, and warn against typical errors.

We will focus on the difference between vacuum cleaners with a separate water tank (for example, Xiaomi Dreame V12) and models where the liquid is poured directly into the main container (as in Mi Handheld Vacuum). You will also learn how to use water for wet cleaning, so as not to clog the filters and not reduce the life of the equipment. If your vacuum cleaner gives an error after pouring water, at the end of the article there is a section with a solution to this problem.

1.How to determine if your Xiaomi vacuum cleaner supports wet cleaning

Not all Xiaomi vacuum cleaners can wash floors – some models are only designed for dry cleaning. To avoid spoiling the device, first check its features:

• 🔍 Model name: the specifications should include a "wet cleaning" or "aquafilter" item. T30, Mi Robot Mop 2 Pro, Deerma VC20.
• 💧 Water tank: if the kit is a separate tank with a lid (usually transparent or with a blue label) – the model supports the function.
• 📄 Instructions: The box or booklet should have a section called “Wet Cleaning” or “Wet Cleaning” on it».
• 🛠️ Nozzles: for wet cleaning there are special brushes with microfibre or rubber blades.

If your model does not meet these criteria (for example, Xiaomi Mi Vacuum Cleaner G10), you can not pour water into it absolutely - this will lead to a short circuit. For dry vacuum cleaners, there are separate accessories for humidifying the air, but they do not replace a full wet cleaning.

2.Where to pour water in Xiaomi vacuum cleaners with a separate tank (Dreame, Deerma)

Most modern models (Dreame V12, Deerma VC20, Xiaomi Mi Robot Mop 2 Pro) have a removable water tank that is attached to the vacuum cleaner body.

1. Remove the tank: press a button or pull a special ledge (usually marked in blue). In Dreame models, the tank is often located behind, in Mi Robot - on top.
2. Open the lid, it can be on latches or threads. In some vacuum cleaners, like the Deerma F600, the lid is transparent, and the water level is visible without opening.
3. Pour water to the mark: there are risks of MIN and MAX on the walls of the tank. You can't exceed MAX, it will lead to leaks.
4. Close the lid and set the tank back: make sure it's up before the click. In Mi Robot models, after installing the tank, press the Reset button on the body.

In Dreame vacuum cleaners T30 and V12 there is an additional compartment for detergent (usually marked with an icon) 🧼). You can add special cleaning fluids, but not more than 10 ml at a time, and you can't use regular soap or detergent, because it will clog the filters.

Disconnect the vacuum cleaner from the socket (for network models)

Remove the water tank and rinse it with warm water

Check the integrity of the sealing rubbers

Only pour purified or boiled water.

Models without a separate tank: how to pour water into the main container

In some Xiaomi vacuum cleaners (such as Mi Handheld Vacuum Cleaner or Dreame V9), water is poured directly into the main vacuum collector, where garbage is also collected. This is less convenient, but has its advantages - you do not need to monitor two containers.

1. Remove the container: Press the Release button (usually red) and pull the container over yourself.
2. Remove the filter: inside the container is HEPA-filter or sponge element, which you have to take out so you don't get wet.
3. Pour water through a special hole: it is marked with a blue lid with a pictogram 💧. Volume - no more than 200 ml (the exact mark is on the wall).
4. Install the filter back: make sure it sits tightly in the slots. In the Dreame V9 models, the filter must be dry - otherwise the vacuum cleaner will not turn on.
5. Return the container to the case and lock before clicking.

⚠️ Attention: If you accidentally get wet HEPA-filter, it needs to be completely dried within 24 hours, and using a wet filter will cause an error. E3 (system clogging) or E5 (motor-problem).

4 What water can be poured into the vacuum cleaner Xiaomi

The quality of water depends on the life of the filters and pumps, and the manufacturer recommends using:

• 💦 Distilled water is ideal, as it does not leave a plaque.
• 🚰 Filtered or boiled water – suitable for most models.
• 🧴 Special vacuum cleaner fluids (e.g. Xiaomi Dreame Cleaning Solution) – no more than 10 ml per 1 liter of water.

❌ It's forbidden to pour:

• Water from the tap (due to chlorine and salts).
• Mineral or carbonated water.
• Soap solutions, bleach, vinegar.
• Fluids for washing glass or floors (except specialized for vacuum cleaners).

If you use tap water, flush the tank after each cleaning to avoid limestone plaque. The Dreame T30 and Mi Robot Mop 2 Pro have a self-cleaning function, which is to press the Clean Tank button and hold the tank under a stream of water for 10 seconds.

💡

If you have hard water in your area, add 1 tbsp of citric acid to 1 liter of water 1 time per month to the tank, which will help dissolve the plaque at the pump.

5. Typical water pouring errors and how to avoid them

Even experienced users sometimes make mistakes that lead to breakdowns.

1. Water overflow: If you exceed the MAX tag, the liquid will enter the engine compartment. In Dreame vacuum cleaners, this causes an E1 error, in Mi Robot, it causes an Error 4.
2. Hot water use: temperatures above 40°C warp plastic and seals. In Deerma models, this can lead to leaks.
3. Pouring water into a dust collector without a filter: if you forget to take out HEPA-filter (in models such as Mi Handheld), it will get wet and fail.
4. Storage of water in the tank: after cleaning, always drain the remaining liquid. Stagnant water becomes a breeding ground for bacteria and unpleasant odor.

⚠️ Warning: If the vacuum cleaner doesn't turn on after pouring the water or shows an error, don't shake it or knock on the body. Unplug the device from the network, drain the water, dry the tank and filters for 12 to 24 hours. If the error is left, please contact the service (the error codes for Xiaomi can be checked in the official Mi Home app).

6 How to care for a water tank: cleaning and disinfection

To vacuum cleaner served longer, and the water does not smell of mustyness, follow these rules:

• 🧽 After each cleaning: drain the remaining water, wash the tank with warm water and dry in air.
• 🧼 1 time per week: wash a tank with mild detergent (such as dish liquid) Avoid abrasives!
• 🦠 1 time per month: disinfect the tank with a solution of vinegar (1: 1 with water) or special tablets for cleaning steam generators.
• 🔧 1 every 3 months: check the sealing gums for wear and tear. If they are worn or deformed, replace them.

The Dreame T30 and Mi Robot Mop 2 Pro have removable microfiber wet-cleaning nozzles, which must be washed by hand at 30°C without bleaching, dried in straightened form, not on a battery, and if the nozzle has lost its shape or become rigid, replace it (original parts can be ordered from the Mi Store or AliExpress).

💡

Never use hard brushes or metal sponges to clean the tank – they scratch the plastic, which leads to microcracks and leaks.
