Xiaomi Robot Vacuum Wrapped in One Place – What to Do? 2026 Step-by-step Guide

Your robot vacuum cleaner Xiaomi Mi Robot, Viomi or Dreame suddenly began to spin pointlessly in one place instead of cleaning the room? S50 Xiaomi’s flagship Robot Vacuum-Mop 2 Pro, which can be attributed to software failures and hardware failures, can be fixed on its own in 80% of cases without going to the service center.

In this article, we will discuss all possible causes, from simple clogging of sensors to firmware errors, and also give step-by-step instructions with photos and videos how to return the vacuum cleaner to work (LDS), Because they're more likely to suffer from these kinds of failures, and if your robot doesn't just spin, but it also squeaks, flashes red, or refuses to charge, we have solutions for these cases.

1. Diagnostics problem: why is the robot vacuum cleaner spinning in place?

Before you start repairing, it is important to understand which node is failing. Xiaomi robots are equipped with several types of sensors, and each of them can cause incorrect behavior:

  • πŸ”΄ Laser rangefinder (LDS) β€” And it's responsible for mapping the space, and if it's contaminated or damaged, it goes blind and it starts to rotate randomly.
  • 🟒 Infrared (IR) Sensors detect obstacles, and when they fail, the vacuum cleaner may not see walls or furniture.
  • πŸ”΅ The gyroscope and the accelerometer are the ones that are responsible for the orientation in space, and if they get lost, the robot loses its coordinates.
  • ⚫ Wheel sensors (encoders) track the distance traveled, and when they are contaminated, the vacuum cleaner thinks it is standing still.
  • 🟑 Bumper and anti-fall sensors – if they jammed, the robot may perceive this as a permanent obstacle.

The problem may also be in firmware (especially after automatic updates) or mechanical damage (for example, after falling from a height).

πŸ“Š How to behave your robot vacuum cleaner Xiaomi?
It's spinning and squeaking.
It's spinning silently, no sound.
Spinning and flashing red/orange
It moves chaoticly, but not in a straight line.
Other

Key sign: if the robot is spinning in a circle (for example, always to the right), the problem is in the gyroscope or one of the wheels. LDS/IR or sensor contamination.

Cleaning sensors and sensors: step-by-step instructions

In 65 percent of cases, the problem is solved by a simple cleaning process, where dust, animal hair and small debris accumulate on the sensors, blocking their operation, starting with the simplest one: mechanical cleaning.

Examine and wipe the laser rangefinder (LDS) dry-cloth|

Clean infrared sensors (usually located around the perimeter) with a cotton swab|

Remove debris from bumper brushes (movable part in front)|

Check the wheels for coiled hair/strands|

Clean the charging sensors (contacts on the bottom)|

Blow compressed air holes anti-fall sensors-->

How to clean LDS-sensor (relevant for models with laser navigation, for example, Xiaomi Mi Robot Vacuum-Mop P):

  1. Turn off the vacuum cleaner and turn it over.
  2. Find a rotating laser module (usually under a transparent cap).
  3. Carefully remove the cap (it can be on latches or screws).
  4. Wipe the lens with a lilac-free napkin dipped in alcohol. Don't use wet wipes!
  5. Blow the insides of the module with compressed air (for example, a canister for cleaning equipment).

If you've had a problem after cleaning, move on to the next step. Don't ignore the wheels' contamination, because the wound hair can block the encoders, which makes the robot think it's not moving and try to move around.

πŸ’‘

Use a toothpick or tweezers to remove hair from the axis of the wheels. Don't pull them, gently scroll the wheel back and pull out the garbage.

Checking of wheels and engines: mechanical failures

If the robot is spinning in one direction or moving in an arc, the problem may be:

  • πŸ”§ The Wheel of the Wheel – Check if it is rotating freely.
  • πŸ”‹ Faulty wheel engine – if one wheel does not turn when switched on.
  • πŸ“ Unbalanced encoders – rotation sensors can give incorrect signals.

How to check the wheels:

  1. Turn the vacuum cleaner over and turn it on in cleaning mode (for example, press the Spot Cleaning button).
  2. See if the two wheels rotate the same way, and if one is standing still, there's a problem with the engine or the transmission.
  3. Try to manually spin the wheel. If it's tight, disassemble it and clear the axle of debris.

For Xiaomi models with independent wheel drive (e.g. Dreame Bot) Z10 Pro) a failure of one engine results in a circular motion, in which case it may be necessary to replace the engine.

How to disassemble the wheel of a Xiaomi robot vacuum cleaner?
1. Remove the side cover (usually it is attached to the 2-3 screw). 2. Disconnect the power connector of the wheel engine. 3. Remove the wheel axis from the grooves (it may require effort). 4. Clean the gears and lubricate them with silicone lubricant (do not use them). WD-40!). 5. Collect in reverse order, making sure the wheel rotates freely.

Attention! If you hear a grinding or a crunch when you spin the wheel, it's a sign of wear and tear on the gears, and you'll need to replace the entire wheel module.

4. Resetting and flashing: software solutions

If the mechanical part is fine, but the robot is spinning anyway, the problem could be the firmware or the downed settings, and let's start with the safest method, soft reset.

How to make a reset to factory settings:

  1. Hold the Home button (or Power) for 10 seconds until the beep sounds.
  2. For models with a screen (for example, Xiaomi Mi Robot Vacuum-Mop 2) select Settings from the Settings menu β†’ Reset β†’ Reset to factory.
  3. After reset, reconnect the vacuum cleaner to the Mi Home application and update the room map.

If the reset didn’t help, try updating the firmware manually:

  • πŸ“± Open the Mi Home app β†’ Choose your vacuum cleaner β†’ Settings of the device β†’ Firmware update.
  • πŸ”„ If the automatic update does not work, download the latest firmware version from the official Xiaomi website (Support section").
  • πŸ’Ύ For manual firmware may be required USB-OTG Adapter (relevant for port models) USB-C, Like Dreame Bot. L10 Pro).

Important: if after updating the firmware, the robot began to spin - this is a sign of incompatibility of the software version. Try to roll back to the previous firmware (instructions are on the forums). 4PDA Xiaomi Community).

πŸ’‘

Before updating your firmware, check user reviews on the new version on the forums. Some updates contain bugs that cause navigational disruptions.

5.Gyroscope problems and calibration

A gyroscope is the vestibular apparatus of a robot vacuum cleaner, and if it gets lost, the vacuum cleaner loses orientation and starts to rotate randomly.

  • The robot always rotates in one direction (for example, only clockwise).
  • After the reboot, it works normally for a short time, then it goes down again.
  • In the Mi Home app, the room map is displayed distorted or turned at an angle.

How to recalibrate the gyroscope:

  1. Place the robot on a flat surface (for example, on a table).
  2. Turn it on and wait for initialization.
  3. In the Mi Home app, go to Settings β†’ Additionally. β†’ Calibration of the gyroscope.
  4. Follow the instructions on the screen (usually wait for the screen to be completed). 1-2 minutes until the robot completes the procedure).

If the calibration doesn’t work, the gyro could fail, which would require replacing the module (at the service center) or buying a new vacuum cleaner, as repairs can cost up to 70% of the price of the device.

πŸ’‘

Before calibrating the gyroscope, make sure the robot is standing on a perfectly flat surface, and even a slight tilt can lead to incorrect calibration.

Errors of laser rangefinder (LDS) and eliminate

Laser rangefinder (LDS) β€” The most vulnerable element in Xiaomi's laser-navigated robot vacuum cleaners, which can fail for several reasons:

Cause of malfunction LDSSigns.Decision
Lens contaminationRobot moves chaoticly, doesn't build a mapCleaning with alcohol and compressed air
Damage to the engine LDSLaser is not rotating, you hear grindingReplacement of the LDS module
Firmware failure LDSLaser flashes red, bug in appUpdate or reset
Mechanical damage (fall)Laser does not turn on, robot does not respond to commandsDiagnostics in the service

How to check LDS:

  1. Turn on the vacuum cleaner and look at the laser module. Normally, it should rotate and emit a laser beam (don't look directly!).
  2. If the laser is not rotating, try to gently scroll it by hand, and if it doesn't, the engine is jammed.
  3. In the Mi Home app, check the status LDS Errors are usually indicated by the LDxx code.

Attention! If the laser module is not rotating and is making a grin, don't try to disassemble it yourself, it could cause a complete failure.

7.When to contact the service: signs of serious breakdowns

Not all problems can be solved by yourself. Contact Xiaomi Service Center if:

  • 🚨 The robot does not turn on or immediately shut down after launch.
  • πŸ”₯ The device smells like a burn or it warms.
  • πŸ”§ Laser module (LDS) It does not rotate or respond to cleaning.
  • πŸ’₯ Robot hits walls despite clean sensors.
  • πŸ”„ After resetting and updating the firmware, the problem returns.

The cost of repair in the official service Xiaomi (2026):

Type of repairCost (β‚½)Date(s)
Cleaning and diagnosis1 500 – 2 5001

Before visiting the service, make a backup copy of the maps of the premises in the Mi Home app (if the robot is still turned on), also save a check or a warranty card - repairs under warranty (if it is valid) will cost free.

8 Prevention: How to prevent repeated failures

To robot vacuum cleaner Xiaomi served a long time and did not β€œgo crazy”, follow the simple rules:

  • 🧹 Clean the sensors after every 5th cleaning (especially if you do not clean them) LDS and IR-sensor).
  • πŸ”„ Update the firmware only through the official Mi Home app.
  • 🚫 Do not drop the robot - even from a height of 30 cm it can damage the gyroscope.
  • πŸ”‹ Use the original power supply - unstable voltage spoils electronics.
  • πŸ“± Calibrate the gyroscope regularly (every 2-3 months).
  • 🌑️ Do not leave the vacuum cleaner in the cold or in direct sunlight.

Advice for owners of models with laser navigation: if the robot often works in dark rooms, install night lights (for example, if the robot works in dark rooms, LED-It's a tape around the perimeter of the room. LDS-sensor better navigate.
