How to turn on the floor wash on the robot vacuum cleaner Xiaomi: instructions for all models

Xiaomi’s wet cleaning robot vacuum cleaners are a godsend for those who value cleanliness effortlessly. However, many users have difficulty first turning on the wash: the app doesn’t find an option, the robot refuses to spray water, then leaves divorces. In this article, we’ll look at all the ways to activate the function, from equipment preparation to fine-tuning in Mi Home or Dreamehome.

It is important to understand that the process differs depending on the model: the Xiaomi Mi Robot Vacuum-Mop 2 Pro algorithm is one, DreameBot has one. W10 — The other, and budget Viomi V3 — And we've put together generic steps that will work for 90 percent of the brand's devices, and we've also identified key differences for the popular lines, so if your robot doesn't spray water or wash it dry, here's the solution.

1. Preparation of the robot for the first wash: what to check before turning on

Before activating the function in the app, make sure the robot is physically ready for wet cleaning. Skipping this stage is the main reason why users encounter errors like "No water in the tank" or "No wash nozzle installed."

Let’s start with the inspection of the components:

• 🔋 Battery Charging: Charge level should be at least 20%. Xiaomi robots lock the sink at low charge to avoid sudden shutdown in the middle of cleaning. Optimal - charge up to 100% before the first start.
• 💧 Water container: Check that the tank is filled with distilled or filtered water (a regular tap water can clog the nozzles). MAX — Don't exceed it.
• 🧹 Cloth/wipe: It should be tightly attached to the holder. If the tissue moves out or lies unevenly, the robot will not recognize it as installed. V3 check the locks on the sides.
• 🔄 Brushes and filters: Make sure the main brush and side rollers are clean – hair-filled parts can block the washing mechanism.

Pay special attention to the type of fabric. The manufacturer recommends using only original napkins or microfiber with a short pile. Long-tail fabrics (for example, terry) absorb too much water, causing the robot to leave wet marks.

⚠️ Warning: If you put a detergent in your tank (even one that's special for robots), don't leave it inside for longer than 24 hours. Chemical additives can eat seals and hoses. After cleaning, always rinse the tank with clean water.

2. activate the wash function in the Mi Home or Dreamehome app

After the robot's physical training, we go to the in-app settings. The interface may vary depending on the firmware and the model, but the overall algorithm is the same. Xiaomi/Mijia (Mi Home app and for Dreame (Dremehome app).

For Mi Home (Mi Robot Vacuum-Mop, Viomi):

1. Select a mode: 🌊 Weak – minimal spraying (for laminate or parquet). 💦 Medium – Standard mode for tiles or linoleum. 🌊🌊 Strong – maximum water consumption (for persistent pollution).

Start

For Dreamehome (DreameBot models) D9/W10/L10):

• In the main menu of the robot, tap on the Moika (icon with a bucket).
• Choose Smart wash (recommended for the first cleaning) or manual mode.
• Set the intensity: 🔹 Quiet - for delicate coatings. 🔹 Standard – Balance between humidity and time. 🔹 Deep - for severe pollution (increases water consumption by 30%).
• Activate the Automatic Spray option if available.

DreameBot models W10 And then there's the self-cleaning function, which is that the robot will automatically wash the napkin after cleaning. → Additionally. → Self-cleaning.

⚠️ Warning: If the app doesn't have a wash button, update the robot's firmware. Outdated versions of the software (especially Viomi's). V2) This function may be hidden. The update is performed in the Settings section. → Update of the PO.

3 Why the robot doesn't wash the floor: Common mistakes and solutions

Even after the right setup, the robot may refuse to spray water, most often due to hardware limitations or software failures, and let's look at typical scenarios and how to fix them.

Problem 1: The robot can drive but not spray water

• 🔌 Pump blocked: Xiaomi and Dreame models have overheating protection. If the robot has been standing in the sun or in a hot room for a long time, the pump can temporarily shut down. Solution: let the device cool for 30 minutes.
• 💧 Clogged nozzles: Check the spray holes (usually at the bottom, next to a napkin.
• 📱 App crash: Reboot the robot (hold the power button for 10 seconds) and reconnect it to Mi Home.

Problem 2: Robot washes dry (the tissue is barely wet)

• 🔧 Incorrect napkin installation: Make sure the fabric is lying with a pile down (in a microfiber, the pile should touch the floor).
• ⚙️ Weak Spray Mode: In the app, select Strong or Deep Mode.
• 🚫 Carpet protection: Xiaomi robots automatically turn off the carpet wash. Check if the long-pile carpet gets into the cleaning area.

Problem 3: No water error with a full tank

This error is caused by a faulty water level sensor or air level sensor in the hoses, to fix it:

1. Remove the tank and check if there are air bubbles inside.
2. Blow the hose connecting the tank to the pump (carefully, without strong pressure).
3. If the error repeats - reset the robot settings to factory (Settings) → Reset).

4. Zone wash setting and schedule

Turning on the washing function alone is not enough to clean efficiently, so that the robot only washes where it needs to and at a time that is convenient for you, set up cleaning areas and schedules.

Zone wash (available in Mi Home and Dreamehome):

1. On the map in the app, click Add Zone (or Custom Area).
2. Circle the area you want to wash (such as the kitchen or corridor).
3. Select the mode Only wash or vacuum cleaner + sink.
4. Set the intensity of spraying (for the kitchen you can choose Strong, for the bedroom - Weak).

Schedule:

• 🕒 At Mi Home, go to the schedule. → Add.
• Choose the days of the week and time (for example, daily at 10:00).
• Specify the type of cleaning: Washer, Vacuum or Combined.
• 🔄 DreameBot models have the option to Repeat at low charge – the robot will return to base, charge and continue cleaning.

Xiaomi Mi Robot Vacuum-Mop P: You can set your schedule to Priority Zones, for example, first the robot will wash the kitchen and then vacuum the bedroom, which saves time and water.

💡

If the robot constantly "forgets" wash zones after updating the map, fix them manually. → It'll prevent you from resetting.

5. Features of the wash for different types of coatings

Not all floors tolerate wet cleaning equally: Xiaomi robots have built-in limitations for delicate coatings, but they can be bypassed or adapted.

DreameBot models W10 and L10 So the robot automatically reduces the intensity of the laminate wash and turns it off on the carpets to activate it:

1. Go to Settings. → Map. → Coating recognition.
2. Turn on the option and wait until the robot updates the map (can take up to 2 cleanings).

If your robot doesn't support automatic recognition, create virtual walls in the app, like encircling a bedroom carpet and setting a vacuum cleaner-only rule for that area.

6.Care for the washing system: how to extend the life of a robot

Incorrect maintenance is the main cause of wash system failures, and following these recommendations will avoid blockages, unpleasant smell and premature wear of parts.

Weekly service:

• 🧼 Tank Washing: After each cleaning, drain the water and wipe the container with a dry cloth. Wash the tank with soap once a week.
• 🧻 Cleaning wipes: Wash the fabric by hand (machine washing spoils the microfiber.
• 🔍 Nozzle Check: Clean the sprayer holes with a toothpick or compressed air.

Monthly maintenance:

• 🔧 Pump cleaning: Dreame models have a removable pump — rinse it under running water. Xiaomi just blows the hose.
• 🧴 Disinfection: Once a month, pour vinegar solution (1:1 with water) into the tank and start the wash for 5 minutes, then rinse with clean water.
• 🔄 Software Update: Check for new firmware – they often fix spraying errors.

What can't be done:

• ❌ Pour bleach into the tank or aggressive detergents.
• ❌ Leave water in the tank for longer than 24 hours (risk of mold).
• ❌ Use fabrics with long pile or waffle towels.

💡

Regular cleaning of injectors and tank increases the life of the pump by 2-3 times. Most of the breakdowns of the wash system are related to clogging, not wear of parts.

7. Comparison of washing functions in different Xiaomi models

If you haven't bought a robot vacuum cleaner yet, or you're thinking about upgrading, compare the power of the washing in popular models, and that's going to help you choose the device you want.

For pet owners, the best choice is DreameBot. W10 or L10. These models are equipped with a self-cleaning fabric system that removes wool and dirt after cleaning, preventing odor. If you want a budget model with a basic wash, look at Viomi. V3 Xiaomi Mi Robot Vacuum-Mop 2 Lite.

Models with a vibration sink (for example, DreameBot) D9) The wipe vibrates at 3,000 rpm, which improves the cleaning of persistent contaminants, but these robots consume more energy and require more frequent tissue replacement.
