How to properly pour water into the robot vacuum cleaner Xiaomi with the function of wet cleaning

Xiaomi’s wet-cleaning robots have become an integral part of the modern smart home. They not only collect dust, but also efficiently clean floors, saving you time. However, improper water pouring can lead to leaks, pump breakdowns, or even a device failure. In this article, we’ll look at all the nuances of the process, from choosing fluids to controlling humidity levels, so that your assistant can last a long time and without failure.

Mi Robot Vacuum-Mop models 2 Pro, Xiaomi Mijia 1T And other detergent devices require a special approach, and the manufacturer warns that using ordinary tap water without preparation reduces the life of parts on the market. 30-40%. We will tell you how to avoid common errors, what fluids are safe for the system, and what to do if the robot suddenly stopped spraying water.

It's important to understand that the process of pouring water depends on the specific model. D9 The tank is integrated into the dust collector and in Viomi V3 We cover all the popular designs so that the instruction is universal.

Preparing a robot vacuum cleaner for pouring water

There are several steps that must be taken before you start pouring, and neglect of preparation is the main cause of failure of pumps and humidity sensors.

First, disconnect the device from the charging station and remove the battery (if designed). In Xiaomi Mi Robot Vacuum-Mop P models, it is simply enough to turn off the power button on the case. Working with the device on can short circuit when moisture hits the contacts.

Second, check the condition of the detergent module:

• 🔍 Inspect the rubber seals on the tank – they should not be cracked or deformed.
• 💧 Make sure the spray holes are not clogged with plaque (especially if you use hard water).
• 🔋 Check the contacts of the water level sensor – oxidation can cause false positives.

The use of distilled or filtered water increases the life of the pump in the 2-3 Xiaomi's manufacturer recommends liquids with no more rigidity than tap water. 3°dH. In regions with hard water (for example, Moscow, St. Petersburg) without filtration is not enough.

What water can be poured into the robot vacuum cleaner Xiaomi

The choice of fluid directly affects the performance of the device, and the manufacturer clearly regulates the water requirements in the instructions, but many users ignore these recommendations.

Permissible options:

• 💧 Distilled water is the ideal choice, leaves no plaque and does not damage the pump.
• 🚰 Filtered water (through reverse osmosis systems or carbon filters) is an acceptable compromise.
• 🧼 Special cleaning products for robot vacuum cleaners (for example, Xiaomi Mi Home Floor Cleaner).

Prohibited options:

• ❌ Tap water without filtration (leads to scale formation).
• ❌ Mineral or carbonated water (corrodes seals).
• ❌ Household vinegar or citric acid (corrodes metal parts).
• ❌ Floor washing products with aggressive surfactants (foam can clog the pump).

In the DreameBot models Z10 Pro and Viomi SE There are water hardness sensors, and if you exceed the permissible level (usually 5).°dH - robot makes an error E3 or E5 And it blocks the cleaning function. If you see this code, you need to flush the system immediately.

⚠️ Attention: Using uncertified detergents voids warranty on robot vacuum cleaner. Xiaomi service centers check the composition of deposits in the pump when diagnosing.

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

Step 2: Inspection and cleaning

• 🧽 Wash the tank with warm water (without detergents!).
• 🔍 Examine the rough cleaning filter (if any) - if contaminated, rinse under running water.
• 🧴 Wipe the level sensor contacts with a dry wipe.

Step 3: Water pouring

• 🚰 Fill the tank with water to mark MAX (usually 200-300 millimeter).
• 🔄 In models with double tank (water) + detergent) fill the special solution in a separate compartment.
• 🔒 Close the lid before clicking - a loose closing will cause an error E2.

Step 4: Installation and test

• 📱 Put the tank back in place and turn the robot on.
• 🤖 Start the test cleaning in Mop mode on 1-2 minute.
• 💦 Check whether the water is sprayed evenly (drops should be visible on the hard floor).

⚠️ Note: Xiaomi Mi Robot Vacuum-Mop 2 Lite models with water overflow MAX The emergency valve fires, and the fluid leaks out through the drainage hole.

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when using robot vacuum cleaners with wash function, and let's look at the most common problems and ways to solve them.

1.The robot doesn't spray water

Reasons:
