Why the right care of Xiaomi robot vacuum cleaner is important for its long run
Xiaomi’s robot vacuum cleaners are not just cleaning gadgets, but complex technical devices with sensors, batteries and mechanical nodes. Without regular maintenance, even the most expensive model (Mi Robot Vacuum-Mop 2 Pro, DreameBot) D10 Plus or Viomi. V3 Pro can fail in 6-12 months, the main problems that owners face: fast battery discharge, navigation errors, loss of suction power and breakage of brushes, all of which can be avoided by following simple but systematic rules of care.
In this article, we will look at all aspects of maintenance, from daily cleaning to in-depth diagnostics, which should be carried out every six months, focusing on the battery (the most expensive component to replace), the filtration system (which depends on the quality of cleaning), and sensors (their pollution leads to “blindness” of the robot), and you will learn what user errors reduce the life of the device by 30-50%, and how to avoid them.
Important: The manual is suitable for all modern Xiaomi models, including the Mi Robot, DreameBot and Viomi lines.However, for devices older than 2019 (for example, Mi Robot). 1S) Additional measures may be required, as we will discuss in the relevant sections.
Daily care: what to do after each cleaning
Even if the robot assistant does the cleaning on its own, it needs minimal care after each use, which will take no more than 3-5 minutes, but will extend the life of the device for years.
- 🧹 Clean the main brush. Remove the coiled hair, thread and debris from the shaft. Use scissors or a special tool from the kit. Don't pull the hair with your hands, it can damage the bearings.
- 🔄 Check the sidebrush. It's usually clogged with hair and dust. Take it off (turn counterclockwise) and rinse it under warm water. Dry it before installation.
- 🗑️ Emptying the garbage container. Don't wait until it's full, it puts more stress on the engine.
- 🔋 Charging station contacts. Wipe them with a dry dust cloth.Oxidized contacts lead to poor charge and errors like Error 10 (can't return to base).
If your robot is equipped with a wet cleaning function (Mi Robot Vacuum-Mop P or DreameBot) W10), After each cleaning, it is necessary:
- 💧 Pour the water out of the tank and rinse it.
- 🧼 Wash a microfiber wipe (if it is removable, wash it manually with a mild detergent).
- 🚫 Do not leave water in the tank for longer than 2-3 hours - this leads to mold and unpleasant smell.
⚠️ Warning: Never use aggressive detergents (such as Domestos or White) to clean your brushes and filters, they destroy plastic and rubber seals, and enough warm water and soft soap.
Deep cleaning: once a week and once a month
In addition to daily care, the robot requires a routine deep cleaning, neglecting these procedures leads to a 40-60% reduction in suction power and navigation errors.
Weekly procedures
- 🔍 Filter HEPA. Take it out of the case (usually under the lid of the garbage container) and vacuum or wash it under running water. Don't rub the filter with a hard brush, it will damage the micropores.
- 🛠️ Sensors and camera (if any) wipe them with a lilac-free napkin dipped in alcohol solution (70% isopropyl alcohol). LDS-The scanner (Mi Robot Vacuum-Mop 2 Pro) 3D-camera (DreameBot) X30 Ultra).
- 🔊 Speakers and microphones. If the robot becomes less responsive to voice commands, check the holes on the body — they often get clogged with dust.
Monthly procedures
- 🔋 Battery contacts: Open the battery compartment lid (if modeled) and clean the contacts with a cotton swab dipped in alcohol. Contact oxidation is one of the causes of Error 5 error (power problems).
- 🌀 The vents are located on the body and cool the engine. Clogged ventilation causes the robot to overheat and automatically shut down.
- 🛑 Wheels and suspension. Remove the coiled hair and check the mobility of the wheels. If they rotate tightly, grease the axle with silicone lubrication (do not use the grease). WD-40!).

For models with self-cleaning tank function (DreameBot) X30 Ultra, Viomi V3 Pro) additionally:
- 🚿 Wash the system of automatic washing of wipes according to the instructions (usually a special detergent is required).
- 🔄 Start a self-cleaning cycle with an empty water tank to remove the residue of detergent.
Battery care: how to extend the battery life
The battery is the most expensive component of a robot vacuum cleaner (it costs 30-50% of the cost of a new device); Xiaomi’s average battery life is 2-3 years if used correctly; however, many users kill it in 6-12 months due to errors.
Basic rules:
- 🔌 Don't keep the robot on charge all the time. Once fully charged (100%), disconnect it from base. Lithium-ion batteries degrade faster when constantly connected to the grid.
- 🔋 Maintain a charge level of 20-80%. Deep discharges (below 10%) and full charges (over 90%) reduce battery life. Use the Power Saving feature in the Mi Home app settings.
- 🌡️ Avoid overheating. Do not place a charging station near heating batteries or in direct sunlight. Optimal operating temperature: 10-35°C.
| Action. | Implications for battery | Recommendation |
|---|---|---|
| Permanent presence on base | Capacity reduction by 20-30% per year | Turn off after full charge |
| Deep discharge (0%) | Irreversible cell damage | Charge at 15-20% charge |
| Operation in the <10°C or >40°C | Accelerated degradation, risk of bloating | Keep it in a cool place |
| Use of non-original RMS | Unstable tension, overheating | Only original accessories |
⚠️ Warning: If the robot is rapidly discharged (for example, it runs 30 minutes instead of the usual 90) and the battery is inflated, stop using immediately.
Critical: After 500 full charge/discharge cycles, battery capacity drops by 30-40%. → The device → Battery status.
💡
If the robot is not in use for a long time (for example, during vacation), charge the battery up to 50% and store it in a cool place.
Cleaning and replacement of consumables
All Xiaomi robot vacuum cleaners have consumables that need to be replaced periodically, and their wear and tear directly affects the cleaning quality and life of the device, and the table below shows the recommended replacement times for the main components.
| Component | Term of service | Signs of wear and tear | Order article |
|---|---|---|---|
| Sidebrush | 3–6 months | Loss of bristles, deformity | CJXJS01ZM (universal) |
| Main brush. | 6–12 months | Wear of bristles, shaft lumpy | ZNMS12WM (most models) |
| HEPA filter | 2-3 months | Reduced suction power, smell | ZNMS11WM |
| Microfiber wipe | 1-2 months | Loss of absorption, ragging | VACMOP01RR (kit.) |
| Dust collector (container) | 1-2 years | Cracks, leakage loss | Depends on the model. |
Where to buy consumables:
- 🛒 Xiaomi's official store.compatibility guarantee, but prices are above the market.
- 🏬 Local service centers, often selling original parts at wholesale prices.
Important: when replacing brushes and filters, be sure to reset the resource meter in the Mi Home app. → Reset the consumable counter, otherwise the robot will show false errors.

Updating the firmware and calibrating the sensors
Robot vacuum software affects its operation as much as mechanical components. Regular firmware updates correct navigation errors, add new features (such as zoning or carpet recognition), and optimize battery consumption.
How to update firmware:
- Open the Mi Home app.
- Choose your robot vacuum cleaner.
- Go to Settings (⚙️) → Firmware update.
- If a new version is available, click Update and wait until it is completed (the robot will restart).
Important: during the upgrade, do not disconnect the robot from power or interrupt the process. This can lead to a "bricking" of the device (loss of performance). If the update has hung for more than 20 minutes, reset:
1. Press and hold the power button for 10 seconds.
2. Connect the robot to the charging station.
3. Repeat the update attempt.Calibration of sensors is required if the robot:
- 🤖 It became worse to navigate in space (hitting furniture).
- 📉 Not seeing obstacles (such as chair legs).
- 🔄 Can't return to base (Error 10).
For calibration:
- Place the robot on a flat surface (not on a carpet).
- In the Mi Home app, go to Settings → Sensor Calibration.
- Follow the instructions on the screen (the robot will perform several test movements).
⚠️ Warning: After updating the firmware or resetting the settings, the robot may "forget" the map of the room, you will have to reconfigure the cleaning areas and virtual walls. To avoid this, export the map to the cloud before upgrading: Map → Save it to the cloud.
💡
Update your firmware at least once every 2-3 months, and newer versions often contain critical fixes for navigation and security.
Storage and transportation: how not to damage the robot
If you plan not to use the robot vacuum cleaner for a while (for example, during a vacation or moving), follow the storage rules to avoid breakdowns:
- 🔋 Battery charge: 40-60% optimal, full discharge or 100% charge when stored damages the battery.
- 🏠 Storage area: dry, cool (10-25)°C, away from direct sunlight. Do not store in a damp basement or on a balcony.
- 🧹 Preparation. Clean the garbage container, remove the brushes and filter. Make sure that the robot is free of moisture (especially for models with wash function).
- 📦 Transportation: If you're carrying a robot, lock the moving parts (brushes, wheels) with tape, or use the original packaging. LDS-scanner.
What can't be done:
- 🚫 Store the robot on the charging station connected to the network.
- 🚫 Putting heavy objects on the robot (such as boxes).
- 🚫 Carry in a lying position without fixation (risk of damage to brushes).
If the robot was stored for more than 3 months before first use:
- Completely discharge and charge the battery (1-2 cycles).
- Check the mobility of the wheels and brushes.
- Update the firmware to the latest version.
Common User Mistakes and How to Avoid Them
Even experienced Xiaomi robot vacuum cleaner owners sometimes make mistakes that shorten the life of the device, and here are the most common ones and ways to avoid them:
- 🧲 Ignoring magnetic tapes: Many users don't use virtual walls or magnetic tapes to restrict cleaning areas, resulting in a robot falling down stairs, getting stuck under furniture or washing carpets (which ruins both the napkin and the coating).
- 🧹 Construction debris cleaners. Robot vacuum cleaners are not designed to collect sand, plaster or sawdust. Small particles clog the filter and engine, causing breakdown. Use a regular vacuum cleaner to repair.
- 🔌 Using non-original chargers: Cheap charges can produce unstable voltages, which cause the battery to overheat and bloat.
- 💦 Excessive washing, so if you wash the floors every day with a robot without drying a wipe, you'll get mold in the tank, and you'll get divorces on the floor.
- 📱 No updates: Older versions of firmware may contain bugs that cause the robot to lose space or see no obstacles.
Another common problem is that the robot doesn't return to base (Error 10).
| Reason. | Decision |
|---|---|
| The charging station is on the carpet. | Move it to a solid, flat surface. |
| Station/robot contact is contaminated | Clean them with alcohol. |
| Weak Wi-Fi signal (for models with a map) | Move the router closer or use a repeater |
| Low battery charge | Charge the robot manually |
If the robot starts making unusual sounds (squeaking, banging, whistling), it's a sign of a mechanical problem.
- 🔧 Foreign object in a brush or wheels.
- 🛠️ Wear of engine bearings.
- 🌀 Fan contamination.
⚠️ If the robot begins to "dance" in one place or move in a spiral, this is a sign of a gyroscope failure or a gyroscope failure. LDS-Don't try to disassemble it yourself, call the service. Wrong calibration can completely disable navigation.
