Which robot vacuum cleaner Xiaomi to choose: a complete guide to models

Choosing an automatic cleaning assistant in Xiaomi’s ecosystem has become a challenge due to the sheer number of models, sub-brands and technical specifications. A potential buyer has to understand not only the suction power, but also the types of navigation, the availability of detergent features and compatibility with a smart home. A mistake in choosing can lead to buying a device that gets stuck on carpets or does not cope well with the fur of pets.

In this article, we will discuss in detail which Xiaomi robot vacuum cleaner is best for your apartment. We will analyze key technologies, compare popular series and help avoid common mistakes when buying. Understanding the differences between LDS navigation and gyroscopes will save you money and nerves in the future.

The market is flooded with Xiaomi, Roborock, Dreame and Viomi brands, all managed through a single Mi Home or Xiaomi Home app, but these devices can vary dramatically in build quality and operating algorithms. Let's define which options are really important and which ones don't make sense to overpay.

Key navigation technologies: LDS vs. gyroscope

The first thing to look at when choosing a navigation system is whether a robot will randomly scatter around a room or build a clear map of a room. The most advanced models are equipped with a laser rangefinder (LDS) located in a characteristic "drum" on the top panel, which allows the device to scan the room in 360 degrees and build an accurate map.

Budget models are often laser-free and rely on a gyroscope or camera (vSLAM).Gyroscopic robots move like snakes, but can lose position when impacted or moved to another location. Chamber systems work well in light, but are useless in the dark. For a complex apartment layout availability LDS-Navigation is a critical factor for effective cleaning.

If you're choosing between a laser model and one without, always use a laser, even if it costs more. The difference in cleaning speed and mapping quality is enormous. Robots with LDS can divide a map into rooms, so you can only clean the kitchen or the hallway.

• 🔹 LDS-Navigation: builds an accurate map, sees in the dark, doesn't crash much.
• 🔹 Gyroscope: Cheap alternative, may be lost, no room division.
• 🔹 vSLAM (camera): good during the day, requires good lighting, is afraid of glare.

⚠️ Note: Models without laser rangefinders often don't know how to save multiple floor maps. LDS necessarily.

Dry and wet cleaning: myths and reality

Many users are looking for a two-in-one device, but it's important to understand the difference between simply wiping the floor and fully washing. Xiaomi's basic models have a static water tank that drips liquid onto the cloth under gravity, which helps refresh the floor but doesn't wash away dried coffee stains or footprints.

More advanced models, such as the Roborock S series or Dreame L, use electronic water control, which allows the system to intelligently dispense moisture depending on the speed of movement and the mode of operation in the application. Some flagships feature a vibrating platform that mimics the movements of the hand when washing the floor.

And here's the rotating disks that rub the floor in circular motions, which are the most efficient method of removing dirt on the market, but these are usually larger and may not fit under low furniture.

For owners of large areas, the problem of frequent water change is the solution, with models with bus stations that change their own dirty water for clean water and dry the cloth with hot air, which eliminates the need to manually perform these actions after each cleaning.

Suction power and work with wool

The suction power parameter measured in Pascals (Pa) often becomes a marketing race. For conventional dust and garbage removal, 2,000-2500 Pa is enough. Values of 4,000-5000 Pa and higher are useful mainly for knocking dust out of carpets or collecting heavy cat hair.

But power isn't the only factor. The design of the main brush is critical. Classic brushes with pile quickly get tangled in hair and wool, requiring constant scissors. Modern models are increasingly equipped with silicone brushes or pileless brushes that almost never wind their hair.

If you have molting animals at home, pay attention to the permeability of the duct. Narrow channels are often clogged with lumps of wool, which leads to a drop in suction efficiency and overheating of the engine. Regular maintenance of the HEPA filter is also necessary to maintain the declared power.

Don't chase maximum power at the expense of running time. In Turbo or Max, any robot's battery will sit in 30-40 minutes. Daily maintenance cleaning is enough to keep up with the standard mode that balances noise and efficiency.

Comparison of popular series: Vacuum, Dreame, Roborock

Xiaomi’s ecosystem includes many manufacturers. The Roborock brand (formerly known as Xiaomi) is considered a premium segment with better algorithms and reliability. Dreame Technology offers great features for less money, often innovating like (bases) before others. The Xiaomi Vacuum series (formerly Mi Robot) is a “middle ground” with good value for money.

There are also sub-brands like Viomi and Roidmi that often have their own apps, which violates the concept of a single smart home.When buying, always check if the device is supported in the mihome or Xiaomi Home app, which will make it easier to set up scripts and integrate with voice assistants.

To illustrate this, we'll compare the key characteristics of typical different price categories in the table below, which will help you navigate the sea of models quickly.

Smart functions and working with the application

The modern robot vacuum cleaner is an Internet of Things (IoT) gadget, and through the app, you can not only start cleaning, but you can also build virtual walls, no-go zones, and set your schedule, for example, telling the child not to clean while the child is sleeping, or you can ignore the area around the pet water bowls.

Integration with voice assistants AliSya, Google Assistant or Yandex Station allows you to control voice cleaning. Automation scenarios work wonders: a robot can go to the cleanup when you leave the house (geolocation of the phone), and return to the base before you arrive.

An important aspect is software updates: manufacturers regularly release updates that improve obstacle-bypass algorithms and add new features. Make sure the brand's servers are running consistently in your area, otherwise a smart home can become "stupid."

Maintenance and durability of the device

Buying a robot is not a one-off action, but the beginning of a relationship that requires care. Consumables (filters, sidebrushes, rags) should be changed regularly. HEPA filters should not be washed with water, they should only be shaken out, and replaced every 2-3 months with new ones to maintain suction power.

Wheelbase and sensors also require attention, and the drop sensors and bumpers need to be wiped with a dry wipe to keep the robot from falling blind and falling from the doorsteps, and the wheels are often clogged with hair that needs to be removed to avoid skewing and navigational errors.

⚠️ Warning: Never leave a robot vacuum cleaner on charge for months without use.Lithium-ion battery can go deep and swell, requiring expensive replacement.

With proper care, a high-quality robot vacuum cleaner lasts 3-5 years. The key to longevity is to clean the main unit in a timely manner and store the device in a dry place. Avoid water on electronic components when washing the dust container.

💡

Tip: Before you start, be sure to walk around the apartment with the robot in mapping mode, which will help the device better remember obstacles and optimize the route.

💡

The best choice for most apartments will be models with LDS-navigation and electronic water supply, as they provide predictable results and convenient control through the application.
