What LiDAR Does & Why It Matters

LiDAR = Laser Navigation System

The spinning tower on top of your Deebot contains:

• Laser emitter and receiver
• Rotating motor (360° spins per second)
• Distance measurement sensors

LiDAR creates room maps by measuring distances. When not spinning:

• ❌ No mapping capability
• ❌ Random cleaning pattern (bumps around like old robots)
• ❌ Can't return to charging station
• ❌ No room recognition
• ❌ No virtual boundaries

Affected Models:

• Ecovacs X2 Omni, X1 Omni
• Deebot T20 Omni, T10 Omni
• Deebot N10 Plus, N8 Pro
• Deebot Ozmo T8 AIVI
• Any Ecovacs with spinning laser tower

• Tower spins slowly or intermittently
• Grinding or clicking noise from tower
• Recently cleaned areas with long hair or pets
• Can see dust/hair around tower base

How to Fix:

Step 1 - Power Off Robot:

1. Hold power button 3-5 seconds
2. Robot turns completely OFF
3. Critical: Don't skip - moving parts present
4. Flip robot upside down for better access (optional)

Step 2 - Inspect LiDAR Tower:

1. Look at top of robot
2. LiDAR is clear plastic dome with spinning mechanism
3. Examine:
   • Base of tower (where connects to robot)
   • Gap between tower and robot body
   • Visible spindle or axle
4. Look for hair, string, or debris wrapped around

Step 3 - Remove LiDAR Cover (If Removable):

For Models with Removable Cover:

1. Gently twist cover counterclockwise
2. Or pull straight up (varies by model)
3. Cover should lift off easily
4. Don't force - some models don't have removable cover
5. Set cover aside safely

For Non-Removable Covers:

1. Work through gap at tower base
2. Use tweezers or cotton swab
3. Don't pry cover off if not designed to remove

Step 4 - Clean Spindle Area:

1. Use tweezers to pull out visible hair
2. Wrap hair around spindle is common
3. Remove ALL hair and debris
4. Use compressed air if available
5. Cotton swab with rubbing alcohol for stubborn grime
6. Let dry 2-3 minutes if used alcohol

Step 5 - Clean LiDAR Lens:

1. Wipe clear plastic lens with microfiber cloth
2. Lens must be crystal clear for mapping
3. Don't use water on electronics
4. Dry cloth or glass cleaner on cloth (not directly on lens)
5. No scratches or smudges should remain

Step 6 - Check for Bearing Obstruction:

1. Look at point where tower spins
2. Should be small bearing or bushing
3. Ensure no debris in bearing
4. Blow out with compressed air
5. Spin tower gently by hand
6. Should rotate smoothly, no resistance

Step 7 - Reinstall Cover (If Removed):

1. Align cover with tower
2. Press down gently or twist clockwise
3. Should click or snap into place
4. Cover should sit flush, not tilted
5. Verify cover secure

Step 8 - Test:

   • Separated components
   • Missing pieces
3. Shine flashlight to see hairline cracks

Step 2 - Check Tower Alignment:

1. Tower should sit perfectly centered
2. Shouldn't lean to one side
3. Gap between tower and body should be even all around
4. If tilted, tower mount may be damaged

Step 3 - Test Tightness:

1. Gently try wiggling tower
2. Minimal movement is normal
3. Excessive play = loose mounting
4. Don't force - just test for looseness

Step 4 - Tighten Mounting Screws (If Accessible):

1. Some models have accessible mounting screws
2. Remove bottom panel if needed
3. Look for small Phillips or Torx screws
4. Tighten gently (don't overtighten)
5. Check if tower now secure

Step 5 - Check Internal Wiring:

Advanced - Only If Comfortable:

1. Remove robot bottom cover (varies by model)
2. Look for wire harness to LiDAR motor
3. Ensure connector firmly attached
4. Check for pinched or damaged wires
5. Reconnect if loose
6. Caution: Warranty may be void if opened

Step 6 - Test Spin Resistance:

1. With robot OFF, manually spin tower
2. Should rotate smoothly
3. If rough spots or grinding:
   • Bearing may be damaged
   • Foreign object inside
   • Gear teeth damaged
4. Note any unusual resistance

Time: 10-15 minutes
Cost: Free (or $30-60 for replacement tower)
Success Rate: 18%
Difficulty: Easy to moderate

Prevent LiDAR Issues

Simple habits that keep LiDAR spinning:

• 🔧 Weekly LiDAR Clean: Wipe dome and check for hair (1 minute)
• 🔧 Avoid Low Furniture: LiDAR hits low overhangs, can damage tower
• 🔧 Monthly Deep Clean: Remove cover and clean spindle thoroughly
• 🔧 Charge Regularly: Low battery can stress LiDAR motor
• 🔧 Handle Carefully: Don't lift robot by LiDAR tower

Avoid These Mistakes:

• ❌ Letting pet hair build up around tower (wraps spindle)
• ❌ Cleaning under furniture lower than robot height
• ❌ Using wet cloth directly on electronics
• ❌ Forcing tower to spin when stopped (damages motor)
• ❌ Ignoring scraping sounds (bearing wear, gets worse)

Common Questions

Can Ecovacs Deebot work without LiDAR spinning?

Yes, but poorly. Robot will switch to basic bump navigation - random pattern like old robot vacuums. No mapping, no efficient coverage, can't find charging dock reliably. You lose 80% of smart features.

How fast should Ecovacs LiDAR spin?

Most Ecovacs models: 300-360 RPM (5-6 rotations per second). Visible as continuous blur when working properly. If you can see individual spokes, spinning too slow - indicates motor issue or obstruction.

Will LiDAR not spinning damage my Deebot?

No immediate damage. Robot will work but navigation is poor. Long-term: Motor attempting to spin against obstruction can overheat and fail completely. Fix promptly to prevent motor burnout.

Can I clean LiDAR with water?

Clean exterior dome with damp cloth - OK. Never spray water inside tower or use wet cloth on spindle mechanism - electronics present, water causes shorts. Use dry cloth or rubbing alcohol on cotton swab.

My Ecovacs LiDAR spins but mapping is poor - why?

Dirty lens or misaligned sensors. Wipe clear dome until crystal clear. If still poor: (1) Recalibrate in app, (2) Delete and remap rooms, (3) Update firmware. Scratched dome also degrades mapping - may need replacement.

How long does Ecovacs LiDAR motor last?

Typical lifespan: 3-5 years with normal use. Heavy use (daily cleaning, large homes): 2-3 years. Signs of wear: slower spinning, intermittent operation, grinding noises. Motor replacement extends robot life significantly.
