Function “Cleaning along the edges of furniture” in vacuum cleaners Xiaomi: the principle of operation, settings and secrets of efficiency

Have you ever noticed how Xiaomi’s robot vacuum cleaner gently “squeezes” against walls, furniture or plinths, as if specifically cleaning dust in the most inaccessible places? This is not a coincidence, but the work of the smart Edge Cleaning feature (in Russian firmware often translates as “cleaning along the edges of furniture”). It has become one of the “chips” of the brand’s modern vacuum cleaners, but not all users understand how it actually works – and especially how to use it correctly.

In this article, we’ll look at what’s behind this feature, from technical implementations (which sensors and algorithms are involved) to practical tips for customizing specific types of rooms. You’ll learn which Xiaomi models support Edge Cleaning out of the box, and where to activate it manually, why the vacuum cleaner sometimes ignores corners, and how to get it to pay more attention to the plinths.

Spoiler: Edge Cleaning works not the same even for vacuum cleaners of the same line - it all depends on the version of the laser rangefinder, the type of brushes and software versions. And we will also reveal one little-known trick, how to use this feature to increase the cleaning coverage by 15-20% without buying additional accessories.

What is Edge Cleaning and How Does It Work in Xiaomi Vacuums?

Edge Cleaning (or “cleaning along the edges”) is a specialized cleaning mode in which the Xiaomi robot vacuum cleaner focuses on treating areas adjacent to walls, furniture, plinths and other vertical surfaces. Unlike standard cleaning, where the vacuum cleaner moves chaoticly or along a predetermined trajectory, here the algorithm forcibly “presses” the device to the edges of the room to collect dust, hair and debris accumulating in the corners.

Technically, the function is implemented through a combination of:

• 📡 Laser sensors (LDS) — Scan the distance to the walls and furniture, adjusting the trajectory.
• 🤖 Algorithms SLAM — build a map of the room and allocate “edge” zones.
• 🌀 Side brushes – rotate at increased speed when approaching the wall, “sweeping” debris to the main suction hole.
• 📱 Software triggers – the firmware contains activation conditions (for example, when an angle or prolonged contact with an obstacle is detected).

It’s important to understand that Edge Cleaning isn’t a separate cleaning mode (like “point” or “zonal”), but an additional layer of logic that turns on automatically during the main cleaning. However, in some models (such as the Xiaomi Mi Robot Vacuum-Mop 2 Pro or the DreameBot Z10 Pro), it can be configured or even disabled through the Mi Home app.

⚠️ Note: If your Xiaomi vacuum cleaner is released before 2020 (for example, Mi Robot Vacuum) 1S), Edge Cleaning can be done in a simplified way, without laser scanning, with side brushes and infrared sensors, and in this case, the efficiency is 30 to 40 times lower%.

What Xiaomi models support cleaning function along the edges

Not all Xiaomi robot vacuum cleaners are equipped with a full-fledged Edge Cleaning function, which depends on the generation of the device, the type of navigation and the firmware version.

If your model is not in the table, check the support for the function through:

1. Mi Home app menu: Go to Device Settings → Cleanup Modes.
2. Technical documentation on the official Xiaomi website (Specifications section).
3. Firmware update: sometimes a feature is added to new software versions (for example, for Mi Robot Vacuum-Mop). 2 Lite after updating to version 3.5.8_0040).

How to turn on and configure cleaning along the edges

In most modern Xiaomi models, Edge Cleaning is activated by default, but it can be optimized for a specific room.

Open the Mi Home app and select your vacuum cleaner|Go to Settings. → Cleaning regimes → Cleaning the edges|Activate the option (if disabled)|Set intensity (if available): Standard, Enhanced or Deep|Save the changes and start cleaning.-->

For models with support for cards (Mi Robot Vacuum-Mop 2 Pro, DreameBot Z10 Pro) additional options are available:

• 🗺️ Manual allocation of zones: In the application, you can circle the edge areas that need to be cleaned more carefully (for example, along the sofa or cabinet).
• ⏱️ Cleaning timer: Set up automatic cleaning of edges on a schedule (for example, once every 3 days).
• 🔄 Repeated passes: Some firmwares have the option of Double Edge Pass).

If the function is not working:

1. Check if the side brushes are blocked (a common problem after a long downtime vacuum cleaner).
2. Update the firmware through Settings → Software update.
3. Reset the map of the room: sometimes errors in it interfere with the correct operation of Edge Cleaning.

💡

If the vacuum cleaner forgets to clean corners, try manually labeling them as “cleaning areas” in the Mi Home app. To do this, click on the map, select Add Zone and circle the problem area.

Why Xiaomi vacuum cleaner doesn’t clean along the edges: typical problems and solutions

Even if Edge Cleaning is activated, the robot can ignore the walls or the boards, and these are the most common reasons and ways to eliminate them:

The side brushes are particularly noteworthy, as their condition directly affects the quality of the edge cleaning. If the brushes are worn or deformed, the vacuum cleaner will not be able to sweep the debris to the main suction hole, check them every 2-3 months and replace them at the first signs of wear (scabbage, lack of bristles).

⚠️ Note: In Xiaomi wet vacuum cleaners (Mi Robot Vacuum-Mop 2 Pro), Edge Cleaning can be turned off automatically when the floor wash is activated, which is associated with the risk of water getting on walls or furniture. To clean the edges worked and wet cleaning, disable the option to Avoid walls when washing in the settings.

Secrets of efficiency: how to make a vacuum cleaner corners better

If the standard Edge Cleaning settings don’t suit you, try these tricks:

• 🔧 Increase the speed of side brushes: In some models (for example, DreameBot) Z10 Pro) has a hidden Side Brush Speed setting. To activate it, go to Settings → Additionally. → Speed of the brush and select High.
• 📏 Optimize furniture arrangement: If there are less than 15 cm between the wall and furniture, the vacuum cleaner may not pass. Move objects away or use virtual walls to mark passageways.
• 🔄 Activate Double Pass: In firmware versions 3.5.8 and higher, there is a Double Edge Pass option that causes the vacuum cleaner to pass along the edges twice.
• 🧲 Use magnetic tape: Stick thin magnetic strips (Xiaomi Mi Magnetic Tape) along the boards – this will help the vacuum cleaner to more accurately determine the boundaries.

Little-known life hack: If your vacuum cleaner supports zoning, create a separate zone 10-15 cm wide along all walls and assign it priority cleaning, so the robot will clean the edges first while the battery is fully charged.

Edge Cleaning vs. Manual Cleaning: Which is More Effective?

Many users are wondering whether Xiaomi's robot vacuum cleaner can replace the manual cleaning of corners with a broom or a vacuum cleaner.

As you can see from the table, Edge Cleaning loses to manual cleaning as a quality, but it wins in regularity, and the best way to do this is to combine both approaches: use a robot to clean the edges every day, and bring the corners to the ideal once a week by hand.

In fact, independent tests (such as the Smart Home Lab YouTube channel) have shown that Xiaomi’s laser-navigated vacuum cleaners (Mi Robot Vacuum-Mop 2 Pro) collect up to 92% of the dust along the boards – provided the side brushes are new and properly calibrated – only 5 to 8 percent worse than manual cleaning!

Updates and future of Edge Cleaning in Xiaomi vacuum cleaners

The Edge Cleaning feature is being developed, and the latest firmware updates for the DreameBot Z10 Pro and Mi Robot Vacuum-Mop 2 Ultra have added new features:

• 🤖 AI optimization: The algorithm analyzes the type of surface (laminate, tile, carpet) and adjusts the speed of the brushes.
• 📊 Edge cleaning statistics: The app now shows what percentage of dust was collected along the walls.
• 🔋 Energy saving: The function automatically shuts down if the battery charge is below 30% so that the vacuum cleaner can return to base.

An update is expected in the near future that will add:

• 🎯 3D-Scanning corners: The vacuum cleaner will “see” bulky obstacles (such as chair legs) and bypass them without losing contact with the wall.
• 🧹 Automatic adjustment of brushes: Sensors will detect the degree of contamination and increase the intensity of cleaning if necessary.

To keep up with updates, follow the announcements in the official Xiaomi community or in the Mi Home Russia Telegram channel. New features are often first tested on Chinese firmware and then ported to global versions.
