How to set up Xiaomi’s wet cleaning robot vacuum cleaner: a complete guide from connectivity to fine-tuning

Why wet cleaning in Xiaomi robot vacuum cleaners requires a special approach

Xiaomi’s wet cleaning robots are not just gadgets for the lazy, but complex devices that combine mechanical cleaning with delicate surface moisture. Unlike conventional dry models, it’s critical to adjust the water intensity, select the right supplies, and consider the type of coating in the house. Mistakes at this stage lead to laminated laminates, flooring overwater, or useless dry wiping.

In this article, we will discuss the unique nuances of wet cleaning customization specifically for the Xiaomi ecosystem (including Viomi and Dreame sub-brands), which the manufacturer often does not mention in standard instructions. For example, why wet cleaning works more efficiently in models with laser navigation (Mi Robot Vacuum-Mop 2 Pro) than in budget versions with a gyroscope, or how to circumvent the restriction on simultaneous dry and wet cleaning in some firmware.

Preparation before the first turn on: what to do before setting up

Before you start setting up, make sure the robot vacuum cleaner is physically ready for wet cleaning. This is not a situation where you can just pour water and start the device.

• 🔋 Charging to 100%. Wet cleaning increases energy consumption by 15-20%. If the battery is discharged lower 80%, The robot can interrupt the process or reduce the intensity of the water supply.
• 💧 In the models Xiaomi Mi Mop 2 and Viomi V3 The water tank must be installed before clicking - otherwise the sensor will not recognize its presence.
• 🧹 Cleaning the main dust collector, and if it's clogged, the robot automatically reduces the suction power, which also affects the quality of the wet cleaning.
• 📱 Update of firmware: Older versions of software (until 2023) may not have had Deep Wet Cleaning.

Pay special attention to the choice of napkin. The manufacturer recommends the use of original microfibre nozzles (Xiaomi Mi Mop Cloth), but in practice, third-party analogues are also suitable - as long as the fabric is not thicker than 3 mm and without a pile, otherwise the pressure sensor will get clogged, and the robot will give an E5 error (clogged water supply system).

Step-by-step setting up wet cleaning through the Mi Home app

The central setup of all wet cleaning options is in the Mi Home app (or Xiaomi Home for newer versions). Consider the process using the Mi Robot Vacuum-Mop 2 Pro example, but the algorithm is relevant for other models with feature support.

1. Open the app and select your robot vacuum cleaner from the device list. Go to Settings → Cleanup modes.
2. Activate the Wet Clean slider. In some firmware, this item may be called Mop Mode or Water Tank.
3. Select the intensity of water supply: Low - for laminate and parquet (consumption ~ 15 ml / m2). The average - for tile and linoleum (consumption ~ 25 ml / m2). High - for persistent contamination (consumption ~ 35 ml / m2, only for water-resistant coatings!).

In the Cleaning Zones section, set up virtual carpet barriers. The robot will automatically pick up the napkin when crossing the border (Carpet Detection only works in models with a laser scanner).

Important: If your model has a Y-shaped cleaning option (for example, in Dreame D9), turn it on for wet cleaning – this increases the surface coverage by 20% due to cross-sectional movements.

Compatibility table: what can and can not be combined

One of the most common mistakes is to try to turn on all the functions at once, which leads to engine overheating or navigational failures.

Note: in models without a humidity sensor (Mi Robot Vacuum-Mop P), you can not simultaneously turn on dry and wet cleaning - this will lead to overloading of the pump and E7 error.

💡

If your robot vacuum cleaner doesn’t save the wet cleaning settings after shutting down, reset it to factory settings via Settings → Reset → Reset cleaning settings. This helps in 80% of failures.

Fine tuning for different types of coatings

There's no universal wet cleaning, and what's perfect for tile is bad for parquet, and we'll look at the optimal settings for each floor type.

Laminate flooring and engineering board

Use low water intensities (15 ml/m2) and turn on wet cleaning no more than 1 time every 3 days. Before cleaning, check the joints of the panels - if they are expanded, water can leak inside. In models with the function of Drying the floor (Viomi V3), activate it for 5-10 minutes after cleaning.

Tile and porcelain

You can use medium or high intensity (25-35 ml/m2) here, but watch the inter-tile seams. If they are porous, water will soak up, leaving the swelling. Solution: pre-treat the seams with a hydrophobic composition or reduce the water flow to 20 ml/m2.

Parquet and massive board

Wet cleaning is only possible with 100% tightness of the coating. Use a minimum water flow (10-12 ml / m2) and an ultra-microfiber nozzle. Before the first cleaning, check the reaction of the parquet: apply a few drops of water to an inconspicuous area and leave for 10 minutes. If there is a stain, wet cleaning is contraindicated.

linoleum

Safe for any intensity, but avoid hot water (above 40°C) - this can warp the coating. In heated water models (Dreame D9 Pro), set the temperature to no higher than 35°C.

Common Mistakes and How to Avoid Them

Even experienced users make mistakes when setting up wet cleaning.-5 problems and solutions:

⚠️ Warning: If Xiaomi’s robot vacuum cleaner starts to “twist” in place after wet cleaning, it’s a sign of overflowing the dirty water tank. Stop cleaning immediately and clean the container – ignoring it will lead to leakage and damage to electronics.

• 🚫 Use detergents. You can only pour water into the tank! The chemistry foams and clogs the nozzles. Use flavoring. 1-2 droplet 500 squash.
• 🚫 Cleaning the wet floor. If the robot comes across a puddle, the flood sensor will go off, and the device will lock until dry (error) E9).
• 🚫 Ignoring the mistake E5. This code means a thin filter clog, wash it under running water and dry it for 24 hours.
• 🚫 Storage with water in a tank. The water left behind leads to bacteria growth and an unpleasant odor.Always drain the leftovers after cleaning.
• 🚫 Using wipes from other brands.Roboock nozzles are 1mm thicker, for example, causing a pressure sensor error.

If the robot has started to "draw" stripes instead of uniform moisturization, check the uniformity of the napkin. In the models of Mi Robot Vacuum-Mop 2 Pro, there is a test: run the "Verification of the napkin" mode in the diagnostic menu (Settings → Diagnostics → Test of the mop system).

Additional features: what can advanced models

Xiaomi’s flagship robot vacuum cleaners offer features that many users don’t even know about. Here’s what you can activate to improve wet cleaning:

• 🔄 Automatic washing of napkins (available in Viomi) V3 dreame D9 Pro) The robot rinses the nozzle in clean water every 5 minutes of cleaning.
• 🌡️ Water heating (only in Dreame) D9 Temperature adjustable from 30°C to 55°C. Set 45 for disinfection°C, but not higher - this reduces the life of the pump.
• 🧼 In the docking station models (Xiaomi Mi Robot Vacuum-Mop 2 Ultra), the robot returns to the base after cleaning, where it washes the dirty water tank.
• 📊 Humidity maps: Laser models build a heat map of the floor and automatically adjust water flow according to the material (Smart Water Control function).

To activate these features, you may need to manually update the firmware through Settings. → Update of the PO → Beta, for example, Deep Cleaning with Heated Water only came in firmware. 3.5.9_0042 for Dreame D9 Pro.

💡

The tank self-cleaning feature cuts manual maintenance by 70%, but requires the use of Xiaomi's original cleansing tablets (ZNMS01JM article).
