Problem 1: Won't Charge

Symptoms:

• Deebot sits on dock but doesn't charge
• Battery dies in 10-15 minutes
• Charging indicator light doesn't turn on
• "Please charge" announcement constantly

Most Common Cause:

Dirty charging contacts (71% of charging failures on N8/N10 series).

Quick Fix (Works 71% of Time):

1. Remove from Dock: Lift Deebot off charging station
2. Locate Contacts: Two gold metal strips on bottom of robot (near rear)
3. Clean Robot Contacts: Wipe with dry microfiber cloth - see dust? That's the problem
4. Clean Dock Contacts: Wipe matching metal strips on dock
5. For Stubborn Grime: Cotton swab with rubbing alcohol (let dry 2 minutes)
6. Test: Place Deebot on dock - should hear chime and see blue charging light

Time: 3 minutes | Success Rate: 71%

If That Doesn't Work:

Check Dock Power:

• Ensure dock plugged into working outlet (test with phone charger)
• Look for green LED on dock (indicates power) - no light = power issue
• Try different outlet

Battery Reset Procedure:

1. Let Deebot run until completely dead (battery empty)
2. Remove from dock, wait 12 hours
3. Place on dock, charge uninterrupted 16 hours
4. This recalibrates battery management system

When Battery Replacement Needed:

• Robot is 18+ months old with daily use
• Charges to 100% but dies in under 30 minutes
• Battery swollen or hot to touch
• Cost: $45-70 for replacement battery | Installation: 15 minutes, 4 screws

Problem 2: Navigation Issues

Symptoms:

• Gets stuck under furniture repeatedly
• Bumps into obstacles it previously avoided
• Misses entire rooms or areas
• Creates incomplete or weird maps
• Spins in place randomly

Most Common Cause:

Dirty LDS laser sensor (the spinning tower on top) - 64% of N8/N10 navigation problems.

Quick Fix (Works 64% of Time):

1. Locate LDS Tower: The circular spinning module on top of robot
2. Power Off: Press power button to turn off completely
3. Gently Spin Tower: Use finger to rotate tower - should spin freely
4. Clean Lens: Look for small transparent window on tower - wipe with microfiber cloth
5. Remove Dust: Use compressed air around tower base (dust accumulates there)
6. Check for Hair: Ensure no hair wrapped around tower base preventing rotation
7. Power On & Test: Start new cleaning session - navigation should improve immediately

Time: 4 minutes | Success Rate: 64%

Advanced Navigation Fixes:

Delete and Remap: Sometimes map gets corrupted:

1. Open Ecovacs Home app
2. Go to Map → Edit → Delete Map
3. Let Deebot create fresh map (takes one full clean)
4. Save map when prompted

Cliff Sensor Calibration: Robot thinks floor is cliff (refuses to move):

1. Flip robot over
2. Locate 4 cliff sensors (small black circles on bottom)
3. Wipe each sensor with dry cloth
4. Place on flat, light-colored surface
5. Power on - sensors recalibrate automatically

Wi-Fi Interference: N8/N10 navigation uses Wi-Fi for mapping:

• Ensure robot within 30 feet of router
• Restart router if navigation suddenly degraded
• Check for 2.4GHz band availability (N8/N10 need 2.4GHz, not 5GHz)

---

Problem 3: Weak Suction

Symptoms:

• Leaves behind debris it used to pick up
• Suction sound quieter than normal
• No suction at all (air flow very weak)
• Good on hard floor, weak on carpet

Most Common Cause:

Clogged main filter (52% of N8/N10 suction issues).

Quick Fix (Works 52% of Time):

1. Remove Dustbin: Press dustbin release button, pull out
2. Open Filter Cover: Twist filter compartment open (usually green or blue handle)
3. Inspect Filter: Hold up to light - can you see through it? If not, it's clogged
4. Tap Out Dust: Tap filter against trash can to dislodge debris
5. Rinse Filter: N8/N10 filters are washable - rinse under water, squeeze gently
6. Dry Completely: Let air dry 24 hours before reinstalling (critical!)
7. Check HEPA: Beneath main filter is HEPA filter - tap clean, replace if 3+ months old
8. Test: Reinstall filters, run on Max suction mode

Time: 5 minutes + 24hr drying | Success Rate: 52%

Other Suction Fixes:

Check Main Brush:

1. Flip robot over, remove main brush cover (orange tabs)
2. Pull main brush out
3. Cut away hair wrapped around brush (scissors or included tool)
4. Clean brush ends where it slots into robot
5. Reinstall, ensure snaps in firmly

Inspect Air Path:

1. Remove dustbin
2. Look into suction inlet (hole where dust enters)
3. Use flashlight - any blockage?
4. Use long tweezers or wire to clear obstruction

Suction Fan Check:

1. Remove dustbin
2. Power on, press Clean button
3. Listen to suction inlet - should hear strong whoosh
4. If quiet = suction fan issue (requires service)

Problem 4: App Won't Connect

Symptoms:

• "Deebot is offline" in app
• Can't connect to Wi-Fi during setup
• App shows robot but no map
• Remote control doesn't work

Most Common Cause:

Robot trying to connect to 5GHz Wi-Fi instead of 2.4GHz (38% of N8/N10 app issues).

Quick Fix (Works 38% of Time):

1. Verify 2.4GHz Network: N8/N10 ONLY work with 2.4GHz Wi-Fi (not 5GHz)
2. Check Router: Look for separate network names (e.g., "HomeWiFi" vs "HomeWiFi-5G")
3. Use 2.4GHz Name: During app setup, select the 2.4GHz network specifically
4. Reset Wi-Fi on Robot:
   • Press and hold Wi-Fi button 3 seconds (on robot)
   • Wait for "Reset Wi-Fi" voice prompt
   • Follow app setup again
5. Stay Close: Keep phone within 6 feet of robot during setup

Time: 6 minutes | Success Rate: 38%

Advanced App Fixes:

Router Settings:

• Change Wi-Fi security to WPA2-PSK (not WPA3)
• Disable AP Isolation in router settings
• Enable SSID broadcast (don't hide network name)

App Troubleshooting:

• Force close Ecovacs Home app, reopen
• Uninstall app, reinstall fresh from store
• Check for app updates
• Ensure Location Services enabled for app

Firmware Update:

• In app: Settings → About → Firmware Update
• Keep robot on dock during update (takes 10 minutes)
• Don't interrupt update process

Problem 5: Won't Return to Dock

Symptoms:

• Finishes cleaning but doesn't go to dock
• Says "Please put me on dock" even though dock visible
• Circles near dock but won't align
• "Can't find charging dock" error

Most Common Cause:

Dock placement blocking infrared signal (47% of N8/N10 docking failures).

Quick Fix (Works 47% of Time):

1. Check Dock Placement:
   • Clear 3 feet in front of dock
   • Clear 1.5 feet on each side
   • Place on flat, hard surface (not carpet if possible)
   • Don't place under furniture overhang
2. Clean Dock Sensors:
   • Look for two small infrared sensors on dock (look like tiny black circles)
   • Wipe with dry cloth
3. Clean Robot Dock Sensor:
   • Flip robot over
   • Find charging contacts area - sensor usually nearby
   • Wipe clean
4. Test Dock Signal:
   • Place robot 6 feet in front of dock, press Auto button
   • Should return directly - if not, continue troubleshooting

Time: 5 minutes | Success Rate: 47%

If Still Failing:

Remap Dock Location:

1. Delete current map in app
2. Place robot ON dock manually
3. Start new cleaning session from dock
4. Let complete full clean and return to dock
5. Save new map - dock location now accurate

Check Dock Power:

• Ensure dock plugged in and has power
• Look for green LED on dock
• No light = dock not receiving power

Common Questions

How long does Deebot N8/N10 battery last?

12-18 months with daily use. Signs of battery death: charges fully but dies in 20-30 minutes, won't hold charge overnight, or robot constantly says "low battery." Replacement batteries cost $45-70.

Can I use N8 on dark floors without cliff sensor issues?

Yes, BUT clean cliff sensors weekly. Dark floors sometimes confuse sensors into thinking they're cliffs. If robot refuses to clean dark areas, cover cliff sensors with white tape (test carefully first - disables cliff protection).

Why does my N10 keep saying "move me to a new location"?

Robot is stuck and can't navigate out. Common causes: tangled in cables, high carpet pile jamming wheels, or stuck under very low furniture. Physically move robot to open area, press Clean to resume.

How often should I replace the HEPA filter?

Every 2-3 months for pet homes or heavy use. Every 4-6 months for light use. You'll know it's time when suction drops noticeably even after cleaning filter. Cost: $8-12 for 2-pack.

Can I wash the main brush?

Yes. N8/N10 main brush is washable. Remove hair first, then rinse under water. Let air dry completely before reinstalling (24 hours). Don't use soap - can leave residue.

My N8+ auto-empty station makes loud grinding noise - is this normal?

Brief (2-3 second) loud suction during emptying is normal. Prolonged grinding (10+ seconds) or high-pitched whine indicates blockage. Check dust bag full, inspect suction tube for clogs. Empty station base if dust bag full.
