Xiaomi window washing robot: should you buy in 2026?

Window washing is a task that many people put off to the last. High floors, fragile frames, or just not wanting to spend a day cleaning make it a real challenge. Here come the robot washers, and Xiaomi offers some of the most technologically advanced solutions on the market. But how do they work in practice? Are pollution better than humans? And most importantly, will expensive equipment fall from the 10th floor?

In this article, we will analyze all models of Xiaomi window washing robots available in 2026, compare their specifications, talk about the nuances of installation and operation, and give an honest assessment: whether to overpay for a smart wash or better return to a traditional rag and bucket.

What kind of window washing robots will Xiaomi release in 2026?

To date, Xiaomi has introduced several models of robot washers, all of which are in the Mi Window Cleaning Robot line, but have key differences in functionality and price.

• 🔹 Xiaomi Mi Window Cleaning Robot 1S — Basic model with application support and security sensors.
• 🔹 Xiaomi Mi Window Cleaning Robot Pro – improved version with laser positioning and increased suction power.
• 🔹 Xiaomi Mijia Glass Cleaning Robot 2 – flagship model with a AI-Frame recognition algorithms and automatic route selection.
• 🔹 Xiaomi Deebot W9 Pro (hybrid model) - combines the functions of a window washer and a robot vacuum cleaner for the floor.

Important: Xiaomi Viomi models (for example, Viomi) V3) They're often marketed as alternatives, but they're coming from a different sub-brand and they have different algorithms. In this article, we'll focus on clean devices. Xiaomi/Mijia.

All robots work on the same principle: they stick to the glass using a vacuum attachment, and then move along a given trajectory, cleaning the surface with microfiber wipes. But the key difference is in the navigation and control system. SLAM-technology (simultaneous localization and mapping) that allows it to bypass obstacles without human intervention.

Technical specifications: model comparison table

To understand which model is right for you, we suggest comparing them by key parameters: Pay attention to the suction power (which determines whether the robot will hold weight on a vertical surface) and battery life, which is critical for large windows.

A critical feature: Xiaomi robots do not work on matte, tinted or embossed glass – they need a smooth surface to create a vacuum. ~5 m complete), so high windows will require an extension with grounding.

⚠️ Warning: if you have double-glazed windows and a window space of more than 2 cm, the robot may not be able to resist – check this before buying with a ruler!

How does a robot for washing windows: a step-by-step principle

The algorithms are similar but different in detail, and let's look at the Mijia Glass Cleaning Robot 2, the smartest version.

1. Preparation: the robot is attached to the glass manually (you need to moisten the wipes with water or a special solution).
2. Scanning: The device analyzes the window boundaries using a laser rangefinder and builds a motion map.
3. Cleaning: The robot follows a Z-shaped trajectory, rubbing the glass with a microfiber. The pressure is adjusted automatically.
4. Safety check: 6 sensors monitor the vacuum level, and when pressure drops, the emergency stop is triggered.
5. Completion: At the end, the robot signals with sound and can return to the starting point.

An important nuance: the robot does not wash the frames and seals - only the glass surface. To completely clean the window, you still need to use a rag or special nozzles (sold separately).

Make sure the glass is dry and clean (without dust)

Wet wipes with distilled water or glassware

Connect the power cable to the grounded outlet

Close all doors and windows (the draft reduces the vacuum)

Install the robot in the bottom corner of the window (for better scanning)-->

The cleaning speed depends on the mode:

• 🐢 Quiet mode - 1.5 m2 / min (for mild pollution).
• ⚡ Intensive regime - 1 m2 / min (for fatty spots).
• 🔄 Double pass – the robot passes the same place twice (increases work time).

Pros and cons of Xiaomi robots for window washing

The advantages of such devices are many, but there are significant limitations. Consider the honest pros and cons based on feedback from owners (data collected from Yandex.Market, AliExpress and Mi Community for 2023-2026).

✅ Advantages:

• 🧹 Saving time: the average window 1,5×1,5 I'm a robot washing for 5–7 minutes (manually would have gone) 15–20 minute).
• 🔒 Safety: No need to lean out of the window on high floors.
• 📱 Smart management: you can start cleaning remotely through the Mi Home app.
• 💧 Water savings: fluid consumption is 3-4 times less than with manual washing.
• 🔋 Autonomy: Pro and 2nd versions hold a charge of up to 40 minutes (enough for 2-3 windows).

❌ Deficiencies:

• 💸 Price: even the basic model will cost more than the services of a cleaning company for a year.
• 🔌 Related to the socket: cable limits mobility (inconvenient for panoramic windows).
• 🚫 Restrictions on glass: does not work on tinting, matte surfaces, stained glass windows.
• 🔊 Noise: level ~60 dB (like a vacuum cleaner), which can interfere with small apartments.
• 🛠️ Service: wipes should be washed after each cleaning, and vacuum pads should be changed every 6 months.

💡

If the robot begins to “slide” down, check the tightness of the vacuum gasket – it can be cleaned with alcohol or replaced (article for Mijia 2: LXDC002).

The special thing is warranty cases: Xiaomi officially guarantees the robot to work only on smooth glass standard thickness, and if the device falls from the window due to surface defects (such as chipping), repair may be refused.

How to choose a robot for washing windows Xiaomi: the criteria for purchase

To avoid disappointment in the purchase, answer these questions before you visit the store:

1. What kind of windows do you have? 🪟 Plastic (PVC) – any model is suitable. 🌲 Wood with relief - only Mijia 2 (with obstacle avoidance function). 🏢 Panoramic (without frames) – you need a model with maximum running time (Pro or Mijia 2).
2. What a glazing area? 📏 Up to 5 m2 - enough basic 1S. 📏 5-10 m2 - Pro. 📏 More than 10 m2 - Mijia 2 or buying a second robot.

Do I need integration into a smart home?

• 🤖 Yes – all models are compatible with Mi Home and voice assistants (Alice, Google Assistant).
• 🚫 No, you can save money and take Viomi. V3 (cheaper, but without AI).

Also consider the climatic conditions:

• ❄️ If windows are often foggy (e.g. in the kitchen), choose a model with drying mode (Mijia 2).
• ☀️ UV protection of wipes is important for the southern regions (they wear out faster in the sun).

💡

If you have windows with a non-standard thickness (for example, 30)+ Check the compatibility with the robot from the seller – some models require additional adapters.

Instructions for the first start and setup

Unpacking and preparing the robot for work takes no more than 10 minutes.

1. Installation of wipes: Moisten the microfiber nozzles with water or special solution (do not use aggressive chemistry!). Fix them on the bottom of the robot - the Xiaomi logo should be on top.
2. Power connection: Put the plug in the socket, then connect the cable to the robot. Make sure there are no overbending - this can lead to overheating.
3. Mounting to the window: Place the robot on the glass in the lower corner, press the Power button and hold for 3 seconds. Wait for the beep (squeaking means the vacuum is created).
4. Configure through the application: Download Mi Home (iOS/Android), Add the device through Add the device → Household care → Windows washing robot. Link the robot to your Wi-Fi network (only) 2,4 GHz!).
5. Mode selection: Options available in the application: 🔄 Auto: The robot chooses its own trajectory. 📐 Manual - control using a joystick in the application. 🧽 Intensive washing - for severe pollution (increases water consumption).

⚠️ Attention: if the robot does not stick to the glass, check: vacuum cleanliness (wipe with alcohol). Glass smoothness (attach a ruler - the gap should not exceed 1 mm). Charge level (at a discharge below 20%, the vacuum weakens).

Frequent problems and their solutions

Even advanced models have failures. TOP-5 problems and ways of eliminating them:

If the robot fell from a window, even from a small height:

1. Shut it off the grid immediately.
2. Check the integrity of the body and vacuum system.
3. Do not turn on if there are cracks - contact the service center.

💡

To extend the life of wipes, wash them manually at 30°C without bleach. Dry in the straightened form without using a battery or dryer.
