How does the robot vacuum cleaner Xiaomi with the function of washing: video + technical analysis

Xiaomi's floorwashing robots have been a real breakthrough in smart cleaning. These devices don't just collect dust, they combine dry and wet cleaning, saving you time and effort. But how does this technology work? Why do some models cope with pollution better than others and some leave divorces? In this article, we'll look at how Xiaomi's cleaning robot vacuum cleaners work, analyze key nodes and show you what to look for when choosing.

If you've ever watched a video of a robot gently skirting obstacles, avoiding carpets while washing, and returning to the base for water refueling, you've probably wondered, "How does it do that?" The answer lies in a combination of laser navigation, humidity sensors, intelligent algorithms, and precision mechanics. Not only will we explain each step of the work, but we'll also warn against the typical errors that shorten the life of the device.

How is the washing robot vacuum cleaner Xiaomi: the main components

Xiaomi's structurally cleansing robot vacuum cleaner is different from the usual one by having a water tank, a water pump and a special microfiber wipe. But that's just the tip of the iceberg. Under the body, there's a complex system where each element plays its part:

• 🔋 Battery – provides autonomy (90 to 250 minutes depending on the model). New devices (for example, Xiaomi Mi Robot Vacuum-Mop 2 Pro) use Li-ion battery capacity of 5200 mAh, which supports fast charging.
• 🧭 Navigation system - laser rangefinder (LDS), gyroscope and cameras for building a map of the room. Models with TrueMapping (for example, Xiaomi Robot Vacuum-Mop) P10) Recognise furniture with accuracy ±1cm.
• 💧 Water pump and reservoir - adjustable water flow (5 to 30 ml / min) and a liquid level sensor. Some models have the function of automatic rinsing of the wipe.
• 🌀 Turbine engine - creates a thinning of up to 2700 Pa (in flagships like Xiaomi DreameBot) X30 Ultra. Responsible for sucking up dust and debris.
• 🧠 Processor and software: chip Cortex-A7 (In the top models, it processes sensor data and it controls the route. AI recognize the types of coatings and adjust the cleaning mode.

The humidity control system deserves special attention. Unlike budget-friendly ones, Xiaomi robots don't just pour water on a napkin, but dose it depending on the type of floor. For example, on laminate, the flow is minimal, and on tile it increases, which prevents flooring from swelling and allows you to use the device on the parquet without risk of damage.

Principle of work: from start-up to completion of cleaning

The cleaning process with Xiaomi washing robot can be divided into 5 key steps, and consider each of them with the example of the Xiaomi Mi Robot Vacuum-Mop 2 Pro:

1. Scanning the room. The robot leaves the base and starts spinning, scanning the room with a laser. In 2-3 minutes, it's created. 3D-map with marked obstacles, carpets and areas prohibited for washing (you can specify them in the Mi Home application).
2. Route planning: The SLAM algorithm (simultaneous localization and mapping) calculates the optimal path, the robot moves in zigzag (cleaning mode) or along walls (washing mode).
3. Dry cleaning. The turbine engine turns on, and the robot sucks in dust, hair and small debris, while the wash wipe is raised to keep it out.
4. Wet cleaning. After dry cleaning is completed (or in parallel, depending on the settings), the robot lowers the napkin, turns on the pump, and starts spraying the water, and the humidity sensor makes sure that the floor is not overmoisturized.
5. Return to base. When the cleanup is complete or the charge is low, the robot returns to the dock on its own. In models with automatic water change (such as the DreameBot X30 Ultra), it also emptys dirty water and fills it with clean water.

The interesting thing is that you can set the priority of zones in the Mi Home app, for example, you can first remove the kitchen (where there is most garbage), and then go to the corridor.

• 🌪️ Turbo – maximum suction power (2700 Pa) for carpets.
• 💦 Intensive washing – increased water consumption for persistent contaminants.
• 🕒 Quiet mode – reduced power for night cleaning.

💡

If the robot leaves a dilution on dark tiles, reduce water consumption in the settings or use distilled water instead of tap water. - It does not contain salts that form a white coating.

Comparison of models: who is better at washing?

Not all Xiaomi robot vacuum cleaners are equally effective in washing, and we analyzed 5 popular models and compiled a comparative table on key parameters:

And you can see from the table that flagship models like the DreameBot X30 Ultra are not only more powerful, they also have automatic water change, which means that the robot, after cleaning, drains the dirty water into a special compartment on the base and fills up with clean water. On budget versions like the 2 Lite, this feature is not available — you have to pour the water by hand.

Another important thing is that carpet recognition is important: in cheap models, a robot can wet the carpet, which leads to mold, and in the top ones (like the P10 or X30 Ultra), the wipe automatically rises when it detects carpeting.

💡

If your house has a lot of carpets, choose a model with the function of AI-recognition of coatings – this will save them from spoilage.

Typical Problems and How to Avoid Them

Even the most advanced robot vacuum cleaners Xiaomi is not immune to problems, here are 3 of the most common complaints users and how to solve them:

⚠️ Attention, if the robot starts leaving strips of dirt instead of washing, check the condition of the microfiber wipe, eventually it gets clogged with fat and stops absorbing water, it is recommended to wash the napkin in the typewriter at 30.°C without air conditioning or replace it every 2-3 months.

• 🔄 The robot doesn't return to base, it could be a weak Wi-Fi signal, or an obstacle in the way, so you can move the dock to an open place and see if the furniture is blocking it.
• 💦 Divorces after washing - caused by hard water or improper mode. Use distilled water and reduce consumption in the application settings.
• 🔊 Heavy noise at work - in models with a suction power of 3000+ If the noise comes on suddenly, check the turbine filter for blockages.

A separate problem is the smell of a water tank, which is when you have a robot standing around with dirty water inside for a long time, to avoid this.

Empty the tank after each cleaning |Wash the tank with hot water 1 time a week |Use special cleaning tablets (e.g. Xiaomi Cleaning Tablets) |Hold a robot with an open lid of the tank for airing-->

If the robot starts to “lose” and chaoticly drive around the room, most likely, the laser sensor (located under the rotating “turret”) has become contaminated.

Video Reviews: What to Watch Before Buying

Before buying a Xiaomi cleaning robot vacuum cleaner, we recommend you to study the video reviews on YouTube.

• 🎥 So, a test on different coatings -- how does a robot handle laminate, tiles, carpet -- for example, in DreameBot reviews. X30 Ultra is often shown avoiding carpets when washing.
• 🔊 Noise level: Compare sound at maximum power. Bedrooms are up to 65 dB.
• ⏱️ Cleaning speed – some models (e.g. Mi Robot Vacuum-Mop 2 Pro) remove 50 m2 in 30-40 minutes, while others spend an hour on it.
• 🛠️ Disassembly and cleaning -- see how easy filters and wipes are to remove. Some models require a screwdriver to do that.

Example of useful channels to view:

• TechnoBard – detailed tests with measurements of noise level and quality of washing.
• Xiaomi Today – Comparisons of the new models with last year’s models.
• Smart Home – reviews with a focus on integration with other Xiaomi devices.

Notice the comments below the video, which often discuss hidden issues that are not mentioned in the review itself, such as DreameBot D9 users complaining of rapid wear of side brushes, and Mi Robot Vacuum-Mop 2 Lite owners complaining of poor suction on carpets.

Exploitation tips: extend the life of the robot

To clean the Xiaomi robot vacuum cleaner last longer, follow these recommendations:

⚠️ Attention! Never use conventional detergents (e.g. Fairy or Mr. Proper) in a water tank! they form foam that can damage the pump. Only special concentrates for robot vacuum cleaners (e.g. Xiaomi Floor Cleaning Solution) are allowed).

• 🔋 Charging: don't keep the robot permanently on base, optimally, charge to 100%, then let it run to 20% before the next charge, and this will prolong the life of the battery.
• 🧹 Cleaning filters - wash off HEPA-filter under running water 1 time per month. Dry it for at least 24 hours before installation!
• 🚫 In the Mi Home app, mark the places where the robot may get stuck (such as a high threshold or wires).
• 🌡️ Temperature: Do not use a robot at temperatures below 5.°C or higher than 40°C. This may cause condensation within the housing.

If you live in a hard water region, rinse your water tank and tubes with vinegar solution once a month (1 part vinegar to 3 parts water) to prevent scaling from forming in the pump.

For pet owners, a good advice is to clean the main brush daily from the wool. In brushless suction models (such as the DreameBot X30 Ultra), this problem is not, but they are more expensive.
