Abnormal Stop during A Task
1. Check if there are any foreign objects entangled in the side brushes, roller brush, or mopping module, if any, clean any.
👉 Freo Z10 Example: Side Brush Maintenance
👉 Freo Z10 Example: Roller Brush Maintenance
2. Check if the LiDAR is abnormal and if the red light display is normal.
3. Check if there are any error messages in the App and solve it accordingly.
👉 Error Code Index and Resolution
If the issue persists, contact support.
Robot Cleaning Extra Areas When Specifying an Area for the Robot to Clean
✨ It is normal.
If it enters both the selected and non-selected zones, this is likely its compensatory cleaning feature activating after corresponding obstacles are removed, which is normal.
Rear Wheel Rotation Fault
Check if there are any foreign objects entangled, if any, clean any.
If the issue persists, contact support.
Relocation Message
1. ✨ It is normal for the robot to trigger the repositioning prompt when it starts if you manually recall the robot after a task is interrupted.
2. If you have moved the base station, remapping is required.
3. Check if the LiDAR is blocked by any obstacles, if any, clean any.
If the issue persists, contact support.
Obstacle Climbing Fault
Please know that the robot can only cross a threshold no higher than 2cm.
1. For complex thresholds approaching 2cm
such as sliding door thresholds, you can try using a threshold ramp for assistance.
👉 How to Install the Narwal Threshold Module?
2. For standard thresholds lower than 2cm
If there is no risk of falling, and the robot cannot cross, you can enable the Stairless Mode.
👉 How to Enable and Disable "Stairless Mode" On Your Narwal Robot?
If the issue persists, contact support.
Robot Falls Down Stairs
👉 How to Prevent Narwal Robot Vacuum from Falling Downstairs?
Robot Not Moving in Straight Line
✨ It is normal.
The robot follows a boustrophedon (back-and-forth) pattern during cleaning tasks. Minor path deviations do not affect cleaning performance.
Robot Gets Trapped under Furniture
The height of the robot body is around 11cm, and the robot radar scan has an inclination angle.
Therefore, the furniture may be identified as an obstacle which leads the robot cannot navigate its way out, leading to it becoming trapped.
✅ To avoid this from happening again, the suggestions are:
1. Raise the furniture.
2. Set the furniture area as a restricted zone.
Robot Spinning
* This issue occurs when the edge sensor is dirty or malfunctioning, causing the robot to falsely detect obstacles and continuously rotate.
Clean the edge sensor.
👉 Freo X Ultra Example: Sensor Maintenance
Robot Re-mopping Not Executed
The robot's built-in dirt sensor detects contamination by analyzing the turbidity and color of wastewater during mop cleaning.
However, it may fail to trigger re-mopping in these cases:
✨ ① Colorless soluble substances (e.g., Sprite, sugar, salt)
✨ ② Pure white stains (e.g., milk, flour)
✨ ③ Light debris (e.g., tea leaves, seaweed flakes, paper scraps)
✨ ④ Insufficient dirt or dried-on stains that don't transfer to wastewater
If re-mopping isn't activated automatically, please manually restart the cleaning cycle.
Robot Scratches Floor or Furniture
The robot's bottom components (side brushes, mop, and wheels) are made of soft materials and won't directly damage floors.
Floor damage may occur if the mopping module or rear wheels are stuck with hard debris.
✅ We recommend starting with a vacuuming task before mopping.
No Air from One Air Outlet during Vacuuming
✨ It is normal.
Only the left opening on the robot is an air outlet, the right one is the speaker.
Speed Reduced
1. Clean the front sensors with a dry cloth.
2. Clean the LiDAR or ensure no obstructions (e.g. lifted stickers or protruding objects) are present on the robot's top cover.
*These may be detected by the LiDAR as obstacles causing unnecessary slowdown.
3. Check if highly reflective materials are present in the area, if so, remove them before retrying operation.
Fast Power Consumption
Confirm the robot was fully charged before starting the task to determine if the issue is rapid power consumption.
If the issue persists, contact support.
