Which robot vacuum cleaner Xiaomi is better to choose with wet cleaning: expert rating 2026

The smart home ecosystem from Chinese giant Xiaomi has long since ceased to be just a set of gadgets for enthusiasts and has become a complete solution for the daily lives of millions of users. Robotic vacuum cleaners are central here, offering functionality that five years ago seemed like fiction. Choosing a model with a wet cleaning function is not just a desire to get a clean floor, but also the need to save time on routine tasks by delegating them to a smart device. Modern algorithms allow the technique not just to rush around the room, but to build accurate maps and remove pollution in complex scenarios.

But the diversity of models in directories can be confusing even for the experienced user: Xiaomi Vacuum, Roborock, Dreame — all of these brands are part of the ecosystem, but offer different technological solutions. Some rely on powerful suction, others on intelligent recognition of obstacles or the ability to automatically clean the base. Understanding these nuances is critical, because the price of devices varies widely, and you do not want to overpay for unnecessary functions.

In this article, we will take a closer look at which Xiaomi robot vacuum cleaner is best for wet cleaning, based on specifications, navigation types and real-world experience. We will look at key parameters that affect cleaning quality and help you determine your priorities. Wet cleaning by robots has come a long way from simple “rag on wheels” to complex systems with vibration and rotation, and these technologies will be the focus of our attention.

Key Wet Cleaning Technologies in Xiaomi Ecosystem

The first thing a buyer encounters when looking at specifications is the different names of wet cleaning technologies. The standard scheme used by the early generations of devices included a water tank and a microfiber mount; water was supplied by gravity or under minimal pressure, often resulting in uneven moisture of the floor; electronic water control was a revolutionary step, allowing liquid to be dispensed with high accuracy depending on the type of coating.

Today, the market leaders are systems with a vibration or rotating platform. In vibra-based models (like VibraRise), the platform performs thousands of vibrations per minute, simulating hand movements when washing the floor with a cloth. This allows you to more effectively wipe old stains. Rotating discs, on the contrary, actively rub the surface, thereby achieving better mechanical impact on pollution. The choice between these technologies depends on the type of flooring in your home.

⚠️ Note: Not all wet-cleaning models automatically lift a rag when you enter the carpet. If you have a lot of carpeting, having a Carpet Boost function or automatic module lifting is a critical parameter, otherwise the carpets can be spoiled.

It is also important to consider the volume of the water tank. For apartments up to 60 square meters, a 200-250 ml tank is enough, but for large areas it is better to focus on models with a tank from 300 ml and above. Some advanced self-cleaning stations, such as the Xiaomi Robot Vacuum X10+, have huge tanks for clean and dirty water, which allows you to forget about hand washing the rag for several weeks.

• 🌊 Type of water supply: Gravitational (obsolete), Electronic (pump), Ultrasonic humidification.
• 🔄 Mechanical impact: Simple wipe, Vibration (Sonic), Rotating disks (Dual Spin Mops).
• 🤖 Intelligence: Carpet recognition, automatic suction enhancement, platform lifting.

So when choosing a device, you need to clearly understand: do you just need to freshen the floor slightly or do you need a full wash? For the first option, the basic model will suit, for the second - a flagship with advanced mechanical impact systems.

Navigation and mapping: LDS vs. VSLAM

The efficiency of wet cleaning depends on how well the robot navigates the space. The chaotic motion characteristic of cheap models without mapping causes some areas to be washed ten times while others remain dry. Xiaomi’s ecosystem is dominated by two main types of navigation: laser (LDS) and visual (VSLAM), a laser rangefinder located on the “turret” on top, scans the room with high accuracy, creating a detailed plan.

LDS-Navigation is considered the gold standard for wet cleaning devices, and it works in complete darkness, it doesn't depend on the texture of the floor, and it allows the robot to map the floor with an accuracy of one centimeter. This allows the Mi Home or Xiaomi Home app to create virtual walls, forbidden zones, and divide the room into rooms, and it is the presence of an accurate map that allows the robot to return to unwashed areas and follow the logic of moving along the walls, then zigzag".

Camera systems (VSLAMs) are less common in top floorwashing models because they are sensitive to light. However, modern hybrid systems using a combination of laser and artificial intelligence camera (AI Obstacle Avoidance) show excellent results. The camera in such models, such as the Xiaomi Robot Vacuum X20+, recognizes wires, socks and other small objects that can get wet and become a problem.

The algorithms for routing Roborock and Dreame (the ecosystem brands) often outpace the native designs of Xiaomi’s core brand. When choosing to choose, you should pay attention to multi-card support if you plan to use a vacuum cleaner on multiple floors. The ability to save up to 4 cards allows the device to quickly navigate after transfer.

• 🗺️ LDS (Laser Distance Sensor: High accuracy, working in the dark, creating detailed maps.
• 📷 VSLAM (Visual Simultaneous Localization and Mapping: Depends on light, is smaller, but less accurate for larger areas.
• 🧠 AI-Camera: Recognises objects, prevents getting stuck, complements the main sensor.

In the end, for high-quality wet cleaning, the presence of a laser rangefinder is almost a requirement. Without it, it is impossible to implement complex cleaning scenarios in rooms and ensure the uniform distribution of water throughout the area of the room.

Comparison of top models: Dreame, Roborock and Xiaomi

To understand which robot vacuum cleaner Xiaomi is better to choose with wet cleaning, you need to conduct a comparative analysis of market leaders. The table below presents the key characteristics of popular models, which are often confused due to the similar design and logo "Mi" on the case.

Xiaomi Robot Vacuum X20+ offers a balance of price and functionality. Rotating wheels provide excellent wash quality, and the base with self-cleaning eliminates contact with dirt. The key feature of this model is the ability to fully maintain the base without human intervention for up to 60 days, making it ideal for busy people. At the same time, Dreame L10s Ultra offers slightly more advanced algorithms for avoiding obstacles thanks to the camera with AI.

The Roborock S7 MaxV stands out for its unique vibratory system. If you have laminate and carpets in your house, the Mop Lift is the most reliable feature here. The robot knows it's on the carpet, lifts the platform, and increases the suction power. This prevents the pile from getting wet, which is often the case with rotating discs that don't always correctly define the boundary of the carpet.

Budget options like the Xiaomi Vacuum Mop 2 Pro+ lack a self-cleaning base but retain laser navigation. This is a great choice for those who are willing to change water and rinse a rag by hand, but want to have a smart room map. However, for full wet cleaning effortlessly, consider the Ultra or Pro series models with automated stations.

⚠️ Warning: When buying a self-cleaning base model, make sure you have a free space around the device (minimum 0.5 meters on each side and 1.5 meters on the front.

Autonomy and self-service systems

The modern robot vacuum cleaner is not just a cleaner, but a standalone station. Battery life directly affects the area that the device can remove in one cycle. The standard indicator for models with laser navigation is 5200 mAh, which allows you to remove up to 250-300 square meters. However, with wet cleaning and high suction power on, real operating time can be reduced.

The most important element of comfort is the self-service base, which can perform three functions: automatic dust discharge, washing of rags and drying. Drying with warm air is a critical function for wet cleaning. If the rag remains moist in a closed container, it quickly develops mold and unpleasant odor. Hot Air Drying models ensure that the process is hygienic.

Also worth noting is the design of the base itself. Some models, like Dreame, have removable tanks that are easy to wash. Others, like some versions of Roborock, require more careful care for the internal channels. The presence of a special floor cleaning solution kit prolongs the life of pumps and tubes, preventing scaling and bacterial plaque.

In a smart home, integration with voice assistants is important; support for Yandex Alice, Google Assistant or Siri allows you to start cleaning with your voice. However, it is worth remembering that all functions, including mapping and zone setting, often require you to install a region in the China app or use special plugins, although global versions are becoming more functional.

Service and typical problems

Even the most perfect robot requires care. The main enemy of wet cleaning systems is lime plaque. If you use high-hardness tap water, the nozzles can become clogged over time and white stains will remain on the floor. Manufacturers recommend distilled water or adding special softeners if the model allows.

Regular cleaning (sensors) is another thing that users forget about: laser rangefinder and drop sensors should be wiped with dry soft cloth at least once a week, dust, settling on the lenses, reduces the accuracy of navigation, and the robot can begin to "get lost" or hit furniture, and periodically clean the side brush, which often wound hair.
