How to pour water into the robot vacuum cleaner Xiaomi: instructions for all models

Xiaomi’s wet cleaning robots have become indispensable tools for cleaning homes, but many users are faced with questions about how to maintain them. One of the most common is how to properly pour water into the tank so as not to damage the device and maximize the efficiency of floor washing. This procedure seems simple, but has nuances that affect the quality of cleaning and durability of equipment.

In this article, we will analyze the step-by-step process of refueling with water for all popular models - from Mi Robot Vacuum-Mop 2 Pro to DreameBot. Z10 Pro, and also the types of water you can and cannot use, you'll learn how to avoid common mistakes that lead to leaks or pump breakdowns, and you'll learn how to optimize water flow for different types of coatings. Particular attention will be paid to models with electronic humidity control - their settings require strict compliance with the instructions.

What Xiaomi models support the function of wet cleaning

Not all Xiaomi robot vacuum cleaners are equipped with a wet cleaning system, a feature available in the following series:

• 🔹 Mi Robot Vacuum-Mop – Hybrid models with a separate water tank (e.g. Mi Robot Vacuum-Mop 2 Pro, Mi Robot Vacuum-Mop P).
• 🔹 DreameBot – Premium devices with electronic water supply control (DreameBot) Z10 Pro, DreameBot L10 Pro).
• 🔹 Viomi - budget options with a simple spray system (Viomi) V3, Viomi SE).
• 🔹 Xiaomi MiJia – Early models with basic washing function (MiJia) 1C, MiJia STYJ02YM).

Models without wet cleaning support (e.g. Mi Robot Vacuum) 1S Mi Robot Vacuum E10) They do not have a water tank and attempts to modify them will lead to irreversible failure of electronic components.

Wet cleaning devices have two types of water supply systems:

1. Gravitational – water flows by gravity through holes in the tank (characteristic for budget models).
2. Electronic – the pump dispenses water at the command of the processor (used in the premium DreameBot series).

What water can be poured into the tank: requirements and restrictions

The type of water directly affects the life of the pump, pipes and wipes for cleaning. Xiaomi recommends using only distilled or boiled water, as indicated in the official instructions for all models.

• 💧 Absence of impurities – mineral salts in tap water settle on the pump and nozzles, over time clogging them.
• 🧼 No chlorine – chlorinated water destroys rubber tank seals.
• 🦠 Sterility – bacteria multiply in standing water that can cause an unpleasant smell.

Alternatives to distilled water:

⚠️ Warning: The use of flavored water or detergents (even diluted ones) is prohibited - this cancels the warranty and can cause corrosion of metal parts. 1-2 droplet (9%) on 1 litre 1 monthly.

The water temperature should be room temperature (18-25)°Hot water deforms the plastic parts of the tank, and cold water can cause condensation inside the housing. In electronically controlled (DreameBot) models, the sensors can falsely act when using water with temperatures above 30°C.

💡

If your area has hard water, after every 5th cleaning, wash the tank with a solution of citric acid (1 tsp. per 0.5 l of water) to remove scale.

Step-by-step: how to pour water into the tank

The water refill process is the same for most models, but there are nuances depending on the type of tank, and here is a universal instruction, taking into account the features of popular devices.

1. Preparation of the robot vacuum cleaner

• 🔌 Turn off the device and remove it from the docking station (if any).
• 🧹 Remove the dust collector – in most models, the water tank is under it.
• 🔄 Check the wipe – it must be clean and properly installed (see section below).

2. Refilling the tank

1. Remove the water tank cover (usually marked with a symbol) H₂O drop-in).
2. Fill the tank with water to mark MAX (DreameBot models have a level sensor — don't exceed it.
3. Close the lid before you click. Make sure the sealing gum is not twisted.

3. Installation of the tank back

• 🔗 Connect the tank to the body before a characteristic click (in Viomi and Mi Robot models, the lock is in front of the tank).
• 🔍 Check the tightness - slightly tilt the robot: water should not leak.

In models with electronic control (DreameBot) Z10 Pro, L10 Pro) after filling the water is necessary:

1. Robot on.
2. In the Mi Home app, select Wet Cleaning mode.
3. Set the intensity level (for example, Medium for laminate, High for tile).

⚠️ Note: In the Xiaomi Mi Robot Vacuum-Mop 2 Pro, the pump must be calibrated when the wet cleaning is first turned on. → Calibrate the water supply and follow the instructions on the screen.

How to choose and install a napkin for wet cleaning

A wipe (or washing nozzle) is a key element of a wet cleaning system that distributes water across the floor and collects dirt. Xiaomi robots come with standard microfiber wipes, but can be replaced with third-party counterparts with improved performance.

Requirements for a napkin:

• 🧺 Material - microfiber with a density of at least 200 g / m2 (for better absorption).
• 📏 Size – should match the model exactly (for example, for Mi Robot Vacuum-Mop) 2 Pro — 24×16 centimeter).
• 🔗 Fastening – Velcros or rubber fixtures should hold the napkin tightly.

Installation instructions:

1. Remove the old napkin (if any) and wash the fastening plate under running water.
2. Spread the new napkin on a flat surface and attach it to the plate, starting from the center.
3. Make sure that the edges of the napkin do not hang and do not interfere with the movement of the wheels.

The life of a wipe is about 3-6 months with regular washing (once every 1-2 weeks).

• 🩹 Poor water absorption – there are divorces on the floor.
• 🦠 Bacteria multiplying - there is an unpleasant smell.
• 🚫 Lock sensors – robot may stop cleaning due to error.

Common Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when refilling water that lead to leaks or reduced cleaning efficiency, the most common of which are:

1. Water overflow – if you exceed the mark MAX, When the robot moves, water can spill over the edge of the tank. In DreameBot models, it will also cause a level sensor error.
2. Using a dirty tank - remnants of old water with dirt particles clog the nozzles. The reservoir must be washed after each cleaning.
3. Incorrect installation of the napkin - if it is displaced, the robot will "drag" it behind it, leaving wet marks.
4. Refilling water with a connected dust collector - this can lead to moisture entering the dust collection system.

How to avoid problems:

• 📏 Use a measuring glass - do not pour water "on the eye".
• 🧼 Wash the tank after each cleaning with warm water with a mild detergent.
• 🔧 Check the mounting of the napkin before each launch.
• 📱 Keep an eye out for in-app notifications – modern models report errors (e.g., “Low water level” or “Nozzle clog").

⚠️ Attention: If puddles remain on the floor after cleaning, this is a sign of a malfunction of the pump or level sensor. In DreameBot models, this problem may be associated with a firmware update - check the relevance of the software in the Mi Home application.

💡

Regular maintenance of the tank and napkin increases the life of the robot vacuum cleaner by 30-40%.

How to Optimize Water Consumption for Different Coatings

The amount of water required for proper cleaning depends on the type of flooring. In Xiaomi electronically controlled robots (DreameBot series), you can adjust the intensity of the water supply in the application. For models with a gravity system (Viomi, Mi Robot Vacuum-Mop), the adjustment is done manually - changing the level of filling of the tank.

To save water in models with a gravitational system:

• 💧 Fill the tank on 2/3 — That's enough for cleaning. 50–60 ².
• 🔄 Use the zigzag mode – it reduces water consumption due to an optimized route.
• 📱 Configure cleaning areas in the application, eliminating carpets (they do not need wet cleaning).

In the DreameBot robots L10 Pro and Z10 Pro is an automatic coating recognition feature, where sensors detect floor material and regulate water supply. If this function is not working properly, update your firmware or manually specify the type of coating in the application settings.

Cleaning and maintenance of the wet cleaning system

For Xiaomi’s robot vacuum cleaner to last, its wet cleaning system needs to be cleaned regularly.The manufacturer recommends full maintenance every 10 cleaning cycles or 1 time per month (depending on the intensity of use).

Checklist for care:

1. Water tank: Rinse with warm water with a soft sponge. Dry in the air (do not use a hair dryer!) Check the sealing gum for cracks.
2. Water nozzles: Clean with a toothpick or compressed air. If you get too clogged, soak it in vinegar for 10 minutes.
3. Pump (for models with electronic feed): Blow the hole to release air. Do not disassemble the pump yourself - this will void the warranty.
4. Washing: Wash by hand at 30°C without bleach. Don't iron it, the microfiber loses its absorbent properties.

For disinfection of the system:

1. Pour into the tank solution (1 liter of water) + 1 tbsp vinegar 9%).
2. Start the robot for 5 minutes in wet cleaning mode.
3. Wash the tank with clean water 2-3 times.

⚠️ Warning: If the robot produces a "Pump Error" error after cleaning (code 10 in DreameBot), this may mean water entering the electronic unit.
