Try This First (4 Minutes)

Before complex troubleshooting, test these instant checks:

• ✅ Clean charging strips (1 minute) - Wipe the three copper charging strips on both robot and dock
• ✅ Check dock power (30 seconds) - Confirm the dock's blue LED indicator is lit
• ✅ Verify docking position (1 minute) - Yeedi needs the charging strips perfectly aligned
• ✅ Power cycle everything (2 minutes) - Unplug dock 60 seconds, hold robot power button 15 seconds

↳ Most Common Cause: Dirty copper charging strips cause 68% of Yeedi charging failures. The Vac 2 Pro's exposed strip design collects dust faster than pogo-pin systems.

Fix 1: Deep Clean Copper Charging Strips (Works 68% of Time)

Why Yeedi Differs: Unlike Roomba's recessed gold pins or Roborock's spring-loaded contacts, Yeedi uses flat copper strips that sit flush with the bottom. This design catches more debris from the floor.

Symptoms:

• Docks properly but charging icon doesn't appear in app
• Intermittent charging (connects, disconnects repeatedly)
• Charging starts but stops after 10-20 minutes
• Battery percentage frozen at same number for hours

How to Fix:

1. Locate Strips: Flip Yeedi over - you'll see three copper strips near the rear (not two like most brands)
2. Dry Wipe First: Use microfiber cloth to remove loose dust and hair
3. Alcohol Treatment: Dip cotton swab in 70% isopropyl alcohol, scrub each strip for 10 seconds
4. Check for Corrosion: Look for green/white buildup - this requires extra scrubbing
5. Clean Dock Strips: The dock has matching strips - clean these identically
6. Dry Completely: Wait 3 minutes before testing (alcohol must evaporate)
7. Test Docking: Place robot on dock - app should show charging within 5 seconds

Time: 5-7 minutes
Cost: Free
Success Rate: 68%
Difficulty: Easy

💡 Yeedi-Specific Tip: The center strip on Yeedi Vac 2 Pro carries data communication, not just power. If only the outer strips are dirty, you'll see charging but the app won't register it properly.

If This Doesn't Work: Try Fix 2 - verify dock positioning

Fix 2: Fix Dock Positioning and Alignment (Works 15% of Time)

Why This Matters: Yeedi's self-empty station (if you have the Pro+ model) has specific weight distribution requirements. Standard docks need stable, level surfaces.

Symptoms:

• Robot approaches dock but misses alignment
• Docks at an angle (not perfectly centered)
• Charging works on some attempts, fails on others
• You hear the robot "hunting" for dock position

How to Fix:

1. Check Surface Level: Use smartphone level app - dock surface must be within 2 degrees of level
2. Verify Clearance: Yeedi needs 1.5 feet clearance on sides, 4 feet in front (more than most brands)
3. Remove Obstacles: Clear any rugs, cables, or furniture within 4 feet of dock
4. Test Surface Stability: Push dock gently - it shouldn't rock or slide
5. Inspect Dock Feet: The four rubber feet on bottom must all contact floor evenly
6. Reposition if Needed: Move to hard, flat surface away from direct sunlight
7. Run Manual Dock Test: Press "dock" button in app to test new position

Time: 8-10 minutes
Cost: Free
Success Rate: 15%
Difficulty: Easy

⚠️ Yeedi Quirk: The Vac 2 Pro's infrared docking sensors sit 2.5 inches from the floor - lower than Roborock's (3 inches) or Roomba's (3.2 inches). This means Yeedi is more sensitive to floor transitions and carpet edges near the dock.

If This Doesn't Work: Try Fix 3 - battery reset procedure

---

Fix 3: Perform Full Battery Calibration Reset (Works 10% of Time)

Why This Helps: Yeedi's battery management chip can lose calibration, reporting incorrect charge levels. This is more common after firmware updates or power surges.

Symptoms:

• App shows 100% but robot dies in 5 minutes
• Battery percentage jumps randomly (50% → 10% → 80%)
• Charging complete notification but robot won't run
• Recently experienced power outage or dock unplugged during charging

How to Fix:

1. Full Discharge: Run robot until it completely stops mid-cleaning (battery empty)
2. Remove from Dock: Take robot off charging station entirely
3. Wait Period: Leave off dock for 8 hours minimum (overnight works best)
4. Unplug Dock Too: Disconnect dock from power during this waiting period
5. Reconnect Everything: Plug dock back in, wait for blue LED
6. Place on Dock: Position robot on dock for uninterrupted 12-hour charge
7. Don't Interrupt: No cleaning cycles during this initial full charge
8. Test Run: After 12 hours, run a complete cleaning cycle to verify

Time: 20 hours total (mostly waiting)
Cost: Free
Success Rate: 10%
Difficulty: Easy (requires patience)

💡 Pro Tip: Yeedi's app will send "fully charged" notification after 4-5 hours, but keep charging the full 12 hours for proper calibration. This resets the battery's internal state-of-charge chip.

If This Doesn't Work: Try Fix 4 - inspect charging strip springs

---

Fix 4: Check Dock Charging Strip Springs (Works 5% of Time)

Why This Fails: Inside the dock, small springs push the charging strips up to contact the robot. These can weaken or get compressed over time.

Symptoms:

• Dock strips don't rise to meet robot
• You see gaps between dock strips and robot bottom
• Charging works if you press down on robot
• Dock is 12+ months old with heavy use

How to Fix:

1. Unplug Dock: Completely disconnect power before inspection
2. Inspect Strip Movement: Gently press each dock charging strip - it should spring back firmly
3. Look for Compression: Strips should sit slightly raised, not flush with dock surface
4. Test Spring Tension: Each strip needs firm push to compress (not mushy or stuck)
5. Clean Around Springs: Use compressed air to remove dust from strip housings
6. Check for Damage: Look for cracked plastic around strip mounting points

Time: 6-8 minutes
Cost: Free (inspection only)
Success Rate: 5%
Difficulty: Moderate

⚠️ Important: If springs are damaged, dock replacement needed ($45-65). Don't attempt to repair internal dock components - risk of electrical issues.

If This Doesn't Work: Try Fix 5 - firmware update

Fix 5: Update Yeedi App and Firmware (Works 2% of Time)

Why This Helps: Yeedi released firmware v2.8.4 in late 2024 that fixed a charging timeout bug affecting Vac 2 Pro models manufactured before June 2024.

Symptoms:

• Charging stops at exactly 80% every time
• App says "charging error" with no specifics
• Problem started after recent app update
• Robot is connected to Wi-Fi

How to Fix:

1. Open Yeedi App: Launch app on your phone (ensure latest version from app store)
2. Check Connection: Verify robot shows "online" status
3. Navigate to Settings: Tap robot icon → Settings → About Device
4. View Current Firmware: Note version (should be 2.8.4 or higher)
5. Check for Updates: Look for "Firmware Update" button
6. Install Update: If available, tap to download (robot must be on dock, 20%+ battery)
7. Wait for Completion: Update takes 8-12 minutes - don't interrupt
8. Restart Robot: After update, hold power button 5 seconds to reboot

Time: 15-20 minutes
Cost: Free
Success Rate: 2%
Difficulty: Easy

💡 Tip: If app won't connect to robot, check your router's 2.4GHz network. Yeedi doesn't support 5GHz Wi-Fi - this is different from Roborock and Roomba which support both bands.

If This Doesn't Work: Battery replacement likely needed

Prevent Future Charging Issues

Maintenance habits that prevent 85% of Yeedi charging problems:

• 🔧 Weekly: Wipe charging strips with dry cloth (45 seconds)
• 🔧 Bi-Weekly: Clean dock charging strips with alcohol swab
• 🔧 Monthly: Vacuum around dock area to reduce dust accumulation
• 🔧 Every 3 Months: Check dock positioning and adjust if needed
• 🔧 Every 6 Months: Run full battery calibration (discharge → 8 hour wait → 12 hour charge)
• 🔧 Yearly: Inspect battery health in app diagnostics

Pro Tip: Set a recurring phone reminder every Sunday morning for charging strip cleaning. Takes under a minute but prevents hours of troubleshooting.

Avoid These Mistakes:

• ❌ Using water or household cleaners on copper strips (causes corrosion)
• ❌ Placing dock on thick carpet (Yeedi needs hard surface for proper alignment)
• ❌ Leaving robot off dock for weeks (deep-discharges battery, shortens life)
• ❌ Using third-party charging docks (incompatible voltage/amperage)

Common Questions

How long does a Yeedi Vac 2 Pro battery last?

Yeedi Vac 2 Pro batteries typically last 12-18 months with daily use, or roughly 300-400 charge cycles. This is average compared to competitors - similar to Eufy and Shark, but shorter than premium Roborock (18-24 months) or Roomba i-series (24-30 months).

Can I leave my Yeedi on the charger all the time?

Yes, absolutely. Yeedi uses smart charging technology that stops current flow when battery reaches 100%, preventing overcharge damage. Leaving it docked 24/7 is recommended by Yeedi and actually extends battery life compared to frequent deep discharges.

Why does my Yeedi show charging in the app but battery percentage doesn't increase?

This indicates dirty charging contacts (most common) or a faulty center communication strip. The app detects dock connection through the center strip, but actual charging happens through the two outer strips. Clean all three strips thoroughly with alcohol.

My Yeedi charges for 2 hours then stops at 50% - what's wrong?

This is typically a firmware bug (fixed in v2.8.4) or failing battery. First, update firmware through the app. If issue persists after update, run full battery calibration (discharge → 8 hour wait → 12 hour charge). Still failing? Battery replacement needed.

Do generic batteries work as well as Yeedi official?

Quality generic batteries (Green Label, Powerextra) perform nearly identically to Yeedi OEM for 40-50% less cost. We've tested them - same 5200mAh capacity, same 60-90 minute runtime. Only difference: Yeedi official includes warranty support.

How do I know if my charging problem is the robot or the dock?

Check the dock's blue LED. LED on = dock is powered and functional, problem likely with robot. LED off or flickering = dock power issue, test outlet or try different power cord.
