Xiaomi Mijia Sweeping Robot G1 is not just a cleaning device, but a full-fledged smart home assistant that can map a room, avoid obstacles and work on a schedule. However, without the right setup, it will not reveal half of its potential. Many users face problems already at the stage of connecting to an application or creating the first map, and features such as zoning or adjusting the suction force are not even aware of.
In this article, we'll go through all the steps of tuning, from basic unpacking to hidden settings that the manufacturer doesn't advertise, how to properly prepare the room before the first cleaning, why the robot can get lost in space, how to get it to bypass carpets with a high pile, and we'll also reveal some unique optimization techniques that reduce cleaning time by 30% without losing quality.
1. Unpacking and preparation for the first launch
Before you turn on the Mijia G1, check the package.
- 🤖 The robot vacuum cleaner itself with a side brush installed
- 🔋 Docking station for charging (with power supply)
- 🧹 Main brush (already installed in some versions)
- 📄 Instructions in Chinese (there is no Russian version, but it is not needed)
- 🔧 Cleaning kit (brush + spare filters)
Pay special attention to the docking station, and it should be placed so that:
- 🔌 The socket was no further than 1.5 meters (the cord is short!)
- 🚫 There was at least 50 cm of free space on the sides.
- 🌡️ The station was not in direct sunlight or near the battery.
- 🪑 Within a radius of 1 meter, there were no chairs, boxes or other objects that the robot could move.
Warning: If you install a dock in a narrow corridor or next to a staircase, the robot may not return to charge after cleaning, at best it will signal an error, at worst it will discharge away from the base.
💡
Before the first cleaning, walk around the room with a flashlight – so you will notice small obstacles (wires, toys, rapids) that the robot may not see.
2. Connect to the Mi Home app
To manage the Mijia G1, you need the Mi Home app (you can download from the App Store or Google Play).
Step-by-step:
- Sign up or sign in to an existing Xiaomi account.
- Click "+" → "Add Device" → select the Smart Home category.
- Find the Mi Robot Vacuum-Mop G1 (not to be confused with other models!).
- Hold the button on the robot body for 3 seconds until you hear the beep.
- Connect to the robot’s Wi-Fi network (the name will be mirobot_XXXX type).
- Return to Mi Home and select your home Wi-Fi network (2.4 GHz! only).
If the robot doesn't connect:
- 🔄 Reboot your router (sometimes changing your Wi-Fi channel to 1-6 helps).
- 📵 Make sure your phone is Bluetooth enabled (required for initial synchronization).
- 🔋 Check the robot's charge (should be at least 20%).
3. First cleaning and mapping of the premises
Once connected, the robot will prompt a test cleaning, so don't miss this step, it's critical for proper mapping.
Remove small objects from the floor (coins, buttons, laces)
Lift curtains and curtains (the robot can catch)
Close doors to non-cleaning rooms
Remove carpets with fringe or high pile
Check that there are no obstacles at the docking station-->
During the first cleaning:
- 🚫 Don't move the robot manually - it knocks the map down.
- 📱 Follow the process in the application (the "Map" tab).
- ⚡ Do not interrupt cleaning until complete (at least 1 complete cycle).
If the robot can't build a map,
- 💡 Increase the lighting in the room (sensors work better in bright light).
- 🔄 Re-start the cleaning from the dock.
- 🧭 Check if there are mirrors or glass surfaces standing in the way (they knock down the laser rangefinder).
What if the robot is stuck in a mapping cycle?
4. Set up schedules and cleaning areas
Once you've created the map, you can set up automatic cleaning on a schedule.
| Parameter | Recommended value | Explanation |
|---|---|---|
| Frequency of cleaning | In a day. | Daily cleaning wears out brushes and filters faster |
| Launch time | 10:00 or 14:00 | Daylights are better for sensors, and there's usually no one at home. |
| Suction mode | Medium (Balanced) | Quiet collects dust weakly, Maximum (Max) consumes battery |
| Moisturizing | Average (if there is a function) | Too wet a regimen can damage laminate flooring |
| Number of passes | 1-2 | More than 2 passes are needed only for heavily polluted areas |
To adjust the zones:
- Open the map in the app.
- Click "Add Zone" and circle the desired area.
- Select zone type: 🧹 Cleaning - the robot will clean only here. 🚫 Forbidden - the robot bypasses this area. 💧 Moisturizing - only wet cleaning (if supported).
Save and assign a zone in the schedule.
💡
If you have multiple floors, create separate maps for each, and move the dock with the robot and start cleaning again.
5. Optimization of work: hidden settings and life hacks
The manufacturer does not mention some of the features of the Mijia G1, which significantly improve its performance:
- 🔧 Turbo Mode for carpets: In the cleaning settings, enable the Carpet Mode option. The robot will automatically increase the suction power on the carpets.
- 🔄 Double corner cleaning: Activate Double Cleaning Corners – the robot will drive around corners twice (good for dust buildup).
- 📡 Real-time map update: Turn on Real-Time Map Update so that the robot adjusts the route as you move furniture.
- 🔋 Energy saving mode: If cleaning is only done during the day, turn off Night Mode, which will save battery life.
To access these settings:
- Open the Mi Home app.
- Go to the device → Settings → Additional settings.
- Scroll down to the Advanced Settings section.
The critical point is, if you turn on Strong Suction Mode on a permanent basis, the robot battery will go down 40 percent faster. Use this mode only for general cleaning.
💡
To prevent the robot from confusing the rooms after rearranging the furniture, before changing the interior, start manual cleaning with the Real-Time Map Update enabled.
Typical errors and their solution
Even when set up correctly, the Mijia G1 can still produce errors, and here are the most common ways to fix them:
| Error code | Reason. | Decision |
|---|---|---|
| Error 1 | Blocked sidebrush | Clean the brush from hair and debris, check its rotation |
| Error 2 | The problem with the main brush | Remove the brush and remove the wound hair/threads |
| Error 5 | Contaminated impact sensor | Wipe the front sensors with a soft napkin. |
| Error 9 | Low battery charge | Put the robot on the dock for 3+ hours |
| Error 12 | The problem with the laser rangefinder | Wipe the glass on the top panel, restart the robot |
If the robot doesn't return to base:
- 🔦 Check if you've blocked the way to the dock.
- 📶 Make sure the robot is in Wi-Fi range (it is guided by the signal).
- 🔄 Reboot the robot (hold the 10 seconds button).
⚠️ Warning: If the robot stopped seeing the map after resetting, don't create a new one right away. First update the firmware through Settings → Software Update - some versions have a card saving bug.
Maintenance and extension of service life
To ensure that the Mijia G1 lasts longer than 3-5 years, follow these guidelines:
- 🧼 Brushing: Remove the hair and threads you've wound weekly, use scissors or a special tool from the kit.
- 🔄 Replace filters: Change the HEPA- filter every 3 months (when used intensively, every 2 months).
- 💧 Tanker care: After wet cleaning, drain the water and dry the container to avoid mold.
- 🔋 Battery: Once a month, discharge the robot to 10% and charge to 100% to calibrate the battery.
For deep cleaning of sensors:
- Turn off the robot.
- Wet the cotton swab in alcohol and wipe it neatly: Laser rangefinder (top rotating part); Infrared sensors (bottom perimeter); Collision sensors (front panel).
Let dry for 10-15 minutes before turning on.
⚠️ Warning: Never use aggressive detergents (such as chlorine) to clean the robot, which can damage plastic and rubber seals, causing moisture to enter the electronic components.
