Even the smartest robot vacuum can sometimes act…well, a little confusing.

If your Narwal robot vacuum isn’t starting, stops midway, behaves oddly during cleaning, or struggles to dock after finishing - don’t worry. Most issues are simple, common, and fixable in minutes.

This complete troubleshooting guide is designed for Narwal India users. It’s practical, easy to follow, and written to help you quickly understand what’s happening and what to do next.

Robot Troubleshooting Before Cleaning

New Robot Does Not Start

Make sure the robot is placed correctly on the powered charging dock.

A new robot may not turn on if:

• It hasn’t charged yet
• It’s not aligned properly with the dock
• The base station isn’t powered

Give it time to charge fully before trying again.

New Robot Reports a System Error on First Task

This can happen occasionally during first-time setup.

Try this in order:

1. Unplug the base station to reboot it
2. Update the robot’s firmware to the latest version
3. Restart the robot

If the error continues, contact support.

Unable to Operate Robot via Base Station

This usually means the robot and base station are not communicating.

Reconnect the robot to the base station and retry.

Robot Already Bound

Rest assured - Narwal robots are sold brand new.

If the app shows the robot is already bound and no one in your home has done it, this may be a factory binding error. Please contact support for resolution.

Robot Starts or Shuts Down Automatically

Check these points:

1. Is scheduled cleaning enabled in the app?
2. Has a family member with shared access triggered it?
3. Is anything pressing the base station buttons accidentally?

If none apply, contact support.

Robot Troubleshooting During Cleaning – Abnormal Behaviour

Robot Stops Suddenly During a Task

Check the basics first:

• Side brushes
• Roller brush
• Mopping module

Remove any tangled hair or debris.

Next:

• Check if the LiDAR red light looks normal
• Open the app and check for error messages

If errors continue, contact support.

Robot Cleans Areas You Didn’t Select

This is normal. The robot may perform compensatory cleaning after obstacles are removed. It’s part of its smart cleaning logic.

Rear Wheel Rotation Fault

Check for foreign objects around the wheels and remove them. If the issue persists, contact support.

Relocation Message Appears

This can happen when:

• You manually recalled the robot mid-task
• The base station was moved
• LiDAR is blocked

If the base station moved, remapping is required.

Obstacle Climbing Fault

The robot can cross thresholds up to 2 cm.

For near-limit thresholds:

• Use a threshold ramp

For lower thresholds:

• Enable Stairless Mode (if safe)

If issues continue, contact support.

Robot Falls Down Stairs

This requires safety adjustments. Set no-go zones or use protective measures to prevent falls.

Robot Not Moving in a Straight Line

This is normal behaviour. Narwal follows a boustrophedon (back-and-forth) cleaning pattern. Minor path changes don’t affect performance.

Robot Gets Stuck Under Furniture

The robot is about 11 cm tall, and its radar scans at an angle. To avoid this:

• Raise the furniture
• Mark the area as a restricted zone

Robot Spinning in Circles

This usually means the edge sensor is dirty. Clean the edge sensor gently and retry.

Robot Doesn’t Re-Mop

The dirt sensor checks wastewater colour and turbidity. Re-mopping may not trigger for:

• Clear liquids (soda, sugar water)
• White stains (milk, flour)
• Light debris (paper, tea leaves)

If needed, restart cleaning manually.

Robot Scratches Floor or Furniture

Narwal components are made of soft materials. Scratches usually happen when:

• Hard debris gets stuck in wheels or mop

Vacuum before mopping for best results.

No Air From One Outlet

Normal. Only the left outlet is for air. The right one is the speaker.

Robot Speed Is Reduced

Try this:

• Clean front sensors
• Clean LiDAR and top cover
• Remove reflective objects nearby

Reflective surfaces can confuse sensors.

Fast Battery Drain

Confirm the robot was fully charged before starting. If power drains unusually fast, contact support.

Cleaning Defects During Cleaning

Waste Leaking

Check:

• Brushes and mopping module for debris
• Dustbin or dust bag fullness

Some leakage while crossing thresholds is normal.

Missed Cleaning Areas

Large areas:

• Remove obstacles
• Ensure rooms were included during mapping
• Check carpet settings

Small areas:

• If dirt was manually wiped mid-clean, the robot may skip it next time

Use zone cleaning to fix this.

Poor Vacuum Performance

For heavy dirt:

• Restart cleaning
• Replace mop module if needed

For stubborn stains:

• Soften with warm water or detergent
• Restart cleaning

Works best with Narwal stain remover.

Side Brushes Scatter Debris

✨ Normal behaviour.

The robot will return in arch mode to clean remaining debris.

Recognition Failures & Collision Issues

Small Obstacle Detection Failure

• Objects under 1 cm may not be detected
• Magnetic strips are not detectable—use no-go zones
  
  

Front or Side Collisions

Check:

• Sensor cleanliness
• LiDAR position

If LiDAR was pressed or impacted, test it on a flat surface.

Issues in Special Environments

Problems may occur with:

• Mirrors or glossy tiles
• Very bright or very dim lighting
• Tight furniture layouts

Ensure proper mapping and lighting.

High-Risk Obstacles (Cables, Power Strips)

Suggestions:

• Enable AI obstacle avoidance – Safety mode
• Set no-go zones

Voice Command Recognition Failure

Check if microphone openings on the radar cover are blocked. If the issue persists, contact support with a video.

Robot Troubleshooting After Cleaning

Robot Fails to Dock

Try this:

1. Clean charging contacts and wheels
2. Reinstall cleaning tray and roller brush
3. Remap if the base station was moved

Robot Pauses Before Docking

This is usually the robot untangling brushes.

• Low noise = side brush untangling
• Loud noise = main brush untangling

It will dock automatically after.

High Water Consumption

Normal when DirtSense technology is active.

Dirty mops get longer washes. Clean ones get shorter cycles.

If needed:

Disable Freo Mode

Adjust mop washing frequency in settings
