The Real Efficiency of Wet Cleaning: Myths and Truth
Many users expect a wet-cleaning robot to clean old stains completely, as a man with a rag and a lot of pressure does. However, the reality is that most Xiaomi models (especially the Lite series or the basic Roborock) are designed to easily dust off and remove fresh traces. The mechanism of action is simple: water flows by itself or under low pressure on a microfiber platform fixed at the bottom.
There's a common misconception that the bigger the water tank, the better the cleaning quality. In fact, the fluid uniformity and the cloth's pressing force are key. Electronically controlled models are significantly better at eliminating puddles and keeping the cloth moist throughout the harvest.
⚠️ Warning: Do not use detergents or chemical solutions in water tanks of Xiaomi robot vacuum cleaners unless expressly authorized by the instruction.Aggressive chemistry can destroy pump seals and cause electronics to fail.
Owners often point out that the ideal result requires a dry cleaning process, and if the robot tries to wash the floor with a layer of wool or large debris, the rag will quickly become contaminated and will simply smear the dirt on the surface, becoming a source of unpleasant odor.
- 🧼 Microfibre – the main working element that requires regular washing and replacement.
- 💧 Intensity – the ability to adjust the water supply level through the application is critical for different types of coatings.
- 🚫 Carpets – most models do not know how to lift the wet cleaning module, so carpets need to be removed in advance.
Why does a robot leave a divorce?
Navigation and mapping: LIDAR vs. gyroscope
One of the main criteria for choosing a navigation is the type of navigation that directly affects the logic of movement and the quality of cleaning in difficult conditions. Xiaomi and Roborock flagship models are equipped with a laser rangefinder (LIDAR) located on the top panel, which allows you to build an accurate map of the room, remember the location of furniture and effectively plan the route without encountering obstacles chaotically.
More affordable versions often use gyroscopic navigation or chaotic motion, which can skip sections, clean the same area longer, or get stuck in dark corners. For apartments with complex layouts, multiple rooms and rapids, LIDAR is almost a prerequisite for comfortable use.
Modern algorithms allow you to save multiple maps, which is important for those who plan to move a robot between floors or apartments. The Mi Home or Roborock app allows you to install virtual walls and exclusion zones, which is especially useful for protecting places with water or fragile objects.
Even laser models can have difficulty with black surfaces and mirrors, as the laser beam is either absorbed or reflected unpredictably, and in such cases manufacturers recommend using special restrictive tapes or virtual barriers in the application.
- 🗺️ Multicards – the ability to save up to 4 floor maps in the device memory.
- 📱 Zoning is a convenient function for cleaning only the kitchen or corridor on a double tap.
- 👀 Visual navigation – some models use a camera to recognize objects (cables, socks).
Comparison of popular models: Roborock, Xiaomi and Viomi
Xiaomi’s ecosystem includes not only its own branded devices, but also products from partners such as Roborock, Viomi and Dreame. Each line has its own characteristics and target audience. For example, Roborock is often positioned as a premium segment with advanced technologies, while the Xiaomi brand (Mi Robot series) covers the mass market.
The Viomi series models often offer unique solutions such as a V-shaped brush or a combined dust and water tank, but may require a separate control application, which creates inconvenience for users accustomed to the single Mi Home ecosystem.
When choosing between generations of the same model, it is worth considering that newer versions often get improved algorithms for avoiding obstacles and more capacious batteries. However, the difference in the quality of dry cleaning between generations can be minimal, since the main traction power of the engine remains similar.
| Model | Type of navigation | Tank (water) volume | Telephone control | Average price |
| :--- | :--- | :--- | :--- | :--- |
| Xiaomi Vacuum Mop 2 | Laser (LDS) | 200 ml | Mi Home / Xiaomi | Medium |
| Roborock S7 | Laser (LDS) | 300 ml | Roborock / Mi Home | High |
| Viomi V2 Pro | Laser (LDS) | 180 ml | Mi Home / Viomi | Medium |
| Xiaomi Essential | Gyroscope | 180 ml | Mi Home | Low |
| Dreame D9 | Laser (LDS) | 270 ml | Mi Home / Dreame | Medium |
⚠️ Note: When buying Viomi or Dreame devices, check the server region in the app. Some models designed for the Chinese market may not connect to European servers without additional manipulation.
If you look at the table, you can see that the volume of the water tank varies slightly, but even 50 ml can give you extra wet cleaning time, and for larger apartments, this can be a crucial factor in keeping the refueling process in check.
Care, maintenance and typical problems
The durability of a robot vacuum cleaner depends on regular maintenance, and the main enemy of any device is the coiled hair and wool on the side brush and main shaft. Despite claims of anti-entanglement, long hair still requires manual cleaning every 1-2 weeks.
HEPA filters need to be changed regularly, especially if you have allergies in the house. Water washing is possible, but requires careful and prolonged drying (at least 24 hours), otherwise mold can form inside the housing or a short circuit may occur.
☑️ Weekly service
Robot wheels also need attention: they often get stuck in small debris, which over time can block movement or damage the motor wheel, and regular cleaning of hard-to-reach places with a small brush will prolong the life of the chassis.
- 🔋 Battery – do not leave the robot discharged to zero for long-term storage, this is detrimental to Li-Ion batteries.
- 🧹 Brushes - side brushes wear out faster than the main ones and require replacement once in a while 3-6 months.
- 👀 Sensors – contaminated fall sensors can cause the robot to start to “fear” dark carpets or steps.
Integration into a smart home and management
Robot vacuum control has long gone beyond buttons on the case. Integration with the Smart Home ecosystem allows you to automate the cleaning process by running it on schedule, when leaving the house or by voice command. Support for Google Home, Amazon Alexa and Yandex.Alice (through third-party integrations) makes management as convenient as possible.
The automation scenarios in the Mi Home app allow you to do wonders, like launching a robot when a smartwatch detects you have left the Home geofence, or turning it off if the front door is open, eliminating the need to remember to start manually.
💡
If the robot loses the card after updating the firmware, try clearing the app cache and restarting the router. Often the problem lies in an unstable Wi-Fi connection during the card data transfer.
However, it is worth considering that for full operation of all functions requires a stable Wi-Fi connection at 2.4 GHz. Many modern routers combine the frequencies of 2.4 and 5 GHz into one network, which sometimes causes problems with connecting old or budget models of robots.
It's also important to keep an eye on software updates. Manufacturers regularly release patches that improve obstacle-bypass algorithms and add new features. Ignoring updates can rob you of useful improvements and bug fixes.
Final recommendations before purchase
Choosing a wet-cleaning robot from Xiaomi is about balancing budget and desired functionality. If you just need a clean cleaner between general cleanings, the mid-range laser-navigated models are the perfect choice.
You don't expect to see the wonders of washing away your dried coffee or cleaning the corners of your room perfectly, but as a tool for daily tidying and dust collection, these devices are proving to be very effective.
💡
The main criterion for choosing is the presence of a laser rangefinder (LIDAR) and the ability to build a map, as this is the foundation for smart and fast cleaning, unlike chaotic movement.
Before placing an order, be sure to check the availability of service centers in your city and the availability of consumables (filters, brushes, rags). The ability to easily buy replacements after 1-2 years of operation is an important aspect of equipment ownership.
Weigh all the pros and cons, study the current reviews for a particular model, because even within the same line, the quality of the assembly and components can vary from batch to batch. A correctly chosen robot will be your faithful assistant for many years to come.
