Xiaomi Mi Robot Vacuum-Mop G1 (or just Xiaomi G1) combines dry and wet cleaning functions, but in order to work properly wet mode, you need to pour water into the tank. Refilling errors can lead to leaks, damage to electronics or poor quality of floor washing. In this article, we will analyze the step-by-step algorithm, the nuances of water selection, volumes for different types of coatings and typical problems faced by owners.
Many users make the same mistake: pouring water over their eyes or using inappropriate liquids (such as detergents), which shortens the life of the vacuum cleaner and can void the warranty, and we will tell you what water you can pour, how often you change it in the tank, and what to do if the robot starts spitting water or leaving divorces.
This article is relevant for all Xiaomi modifications G1, including versions with self-cleaning tank and support LDS-If you have a different model (e.g. Xiaomi) S7 or dreame W10), instructions may differ - specify in the documentation for the device.
Preparing a robot vacuum cleaner for pouring water
Before you pour the water, make sure the robot is off and standing on a flat surface. Do not manipulate while charging or cleaning, this can cause the program to crash.
- 🔋 Battery charge: at least 20%, low charge, robot can interrupt cleaning, leaving water in the tank, which will lead to stagnation.
- 🧹 Clean containers: remove garbage from the dust collector and wash the wipe for wet cleaning (if it is removable).
- 💧 Reservoir condition: inspect the water tank for cracks or lime plaque, and if you find contaminants, rinse it with warm water.
If you are using a robot for the first time, check out the user manual, which lists the maximum amount of water for your model (usually 200-250 ml) and recommendations for the care of a napkin. For the Xiaomi G1, the optimal level is 180-220 ml depending on the area of the room.
⚠️ Note: Do not pour water into the vacuum cleaner if the room temperature is lower +5°C. This can cause the liquid in the hoses to freeze and damage to the pump.
What water can be poured into the Xiaomi G1
The manufacturer recommends using only clean drinking water at room temperature.
- 🧼 Soap solutions or floor washing products - they can damage the pump and leave a sticky plaque.
- 🌡️ Hot water (above 40)°C) - deforms plastic parts of the tank.
- 💊 Fragments or flavors – clog filters and can cause allergies.
- 🧂 Hard water with a high salt content - leads to lime plaque in the tubes.
If your area is hard water, use distilled or filtered. To disinfect the wipe, you can add 1-2 drops of vinegar (9%) per 1 liter of water, but no more than 1 time per month.
| Type of water | Can I use it? | Consequences of violation |
|---|---|---|
| Drinking bottled | ✅ Yes. | No. |
| Plumber (filtered) | ⚠️ Conditionally. | Lime plaque at stiffness > 7 mg-eq/l |
| Distilled | ✅ Yes. | No. |
| Mineral carbonated | ❌ No. | Pump damage, corrosion of metal parts |
| With detergent | ❌ No. | Foam in the tank, sensors broken down. |
💡
If there are stains after cleaning, try reducing the amount of water to 150 ml or using a microfiber napkin with a denser pile.
Step-by-step: how to pour water into the tank
The refueling process takes no more than 1-2 minutes.
- Open the water tank cover by pressing the latch (usually located on the top panel of the robot).
- Remove the container and rinse it under running water if there is any residue of liquid from past cleaning.
- Pour water to the MAX mark (or 180-220 ml). Use a measuring glass for convenience.
- Set the tank back, making sure it is tightly fixed (a click should be heard).
- Attach a wet cleaning napkin to the bottom of the robot. It should lie flat, without folds.
After refueling, check the leakproofness: tilt the robot slightly forward, the water should not leak out. If you notice a leak, remove the tank and check the integrity of the sealing gum.

⚠️ Warning: If the robot makes uncharacteristic sounds (gurgling, grinding) after pouring water, turn it off immediately and check the tank for air in the hoses.
Setting up the wet cleaning mode in the Mi Home app
The water is only half the battle, and in order for the robot to clean the floors effectively, you have to adjust the parameters in the app correctly.
- Open the Mi Home and select your Xiaomi G1.
- Go to Cleaning Settings → Wet Cleaning Mode.
- Select intensity: Weak (for laminate, parquet) - minimum water consumption; Medium (for tile, linoleum) - standard mode; Strong (for persistent contaminants) - maximum flow.
Activate the option of Zigzag cleaning for even distribution of water.
For rooms with different types of coatings (such as kitchen tile and living room laminate), adjust cleaning areas with separate humidity parameters to prevent damage to sensitive surfaces.

Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when refilling water.
- 🚫 Water overflow: If you pour more than 220 ml, the robot will leave puddles. The solution is to drain the excess and wipe the bottom with a napkin.
- 🔄 Using dirty water: residues from past cleaning may bloom.Always rinse the tank.
- 🧽 Untimely wipe replacement: If the fabric is worn out, the robot will smear the dirt. Change it after 3-5 cleanings.
- ⚡ Pouring water at low charge: the robot can “hang” in the middle of the room, not having time to return to the base.
If a robot stops in the middle of a cleaning operation with a Water tank error, it could mean:
- The tank is not tightly closed.
- The filter or the water supply hose is clogged.
- The fluid level sensor is defective.
In the first two cases, the problem can be solved independently (cleaning, washing), in the third - a service center will be required.
💡
Use only original wipes from Xiaomi or certified counterparts. Cheap fakes can not absorb water and damage the mounting mechanism.
How to Care for a Water Tank
To extend the life of the container and avoid unpleasant odor, follow simple rules:
- After each cleaning, drain the remaining water and dry the tank in the air (not in direct sunlight).
- Once a week, wash the container with acetic solution (1 part vinegar to 3 parts water) to remove plaque.
- Check the sealing gum for wear - if cracks appear, replace it.
- Keep the robot in a dry place, avoiding wet spaces (such as the bathroom).
If a black coating (mold) appears in the tank, soak it for 1 hour in a solution of soda (2 tbsp. spoons per 1 liter of water), then thoroughly rinse. Hydrogen peroxide (3%) can be used for disinfection, but no more than 1 time in 2 months.
Alternative ways to refill water (for experienced users)
The standard pouring method is suitable for most tasks, but in some cases it is possible to optimize the process:
- 💧 Partial refueling: for small rooms (up to 20 m2), 100-150 ml of water is enough. This reduces the weight of the robot and the consumption of a wipe.
- 🔄 Automatic refueling: if you have a model with a self-cleaning base (e.g. Xiaomi) G1 Pro, the robot itself fills up water when returning to the station.
- 🧴 Use of special capsules: some users add flavoring capsules to the water (such as Xiaomi Aromatic Capsule), but this is not an official recommendation.
For deep cleaning of highly contaminated floors, you can use the steam mode (if it is supported by your model), but only on tiles or stone - steam will damage laminate and parquet.
⚠️ Attention: If you're experimenting with alternative methods, watch the robot's response. E10 or E11 In the Mi Home app, you can signal problems with the water supply system.
