Try This First (3 Minutes)

Quick checks before detailed troubleshooting:

• ✅ Restart both robot and station (2 minutes) - Power off 30 seconds, power back on
• ✅ Check Yeedi app connection (30 seconds) - Open app, verify robot shows "Online"
• ✅ Clean front 3D sensor (30 seconds) - Wipe black lens on front bumper
• ✅ Empty station dust bag (1 minute) - If bag light blinking, replace bag

↳ Most Common Cause: Auto-empty station dust bag full (42% of Yeedi Vac 2 Pro issues). The bag sensor is very sensitive.

Fix 1: Auto-Empty Station Won't Empty - Check Bag and Seal (Works 42% of Time)

Why Yeedi-Specific: Vac 2 Pro's self-empty station uses a disposable bag with a rubber seal. If seal doesn't sit flush, suction fails completely.

Symptoms:

• Robot docks but auto-empty doesn't trigger
• Station makes weak sucking sound for 5 seconds, stops
• Blue "bag full" light blinking even with new bag
• Auto-empty worked yesterday, stopped today

How to Fix:

1. Open station lid - Press lid release button on top of auto-empty station
2. Check bag fullness - Dust bag should be less than 80% full - if bulging, replace
3. Remove bag - Pull cardboard handle straight up
4. Inspect sealing plate - White rubber seal on bag opening should be clean, not dusty
5. Clean station inlet - Where bag connects, wipe plastic rim with dry cloth
6. Proper bag installation - New bag slides in until you feel resistance, push firmly until click
7. Test seal - Lift bag gently - should not come out easily (good seal)
8. Run manual empty - In Yeedi app: More → Manual Dust Collection (should run 10 seconds)

Time: 5 minutes
Cost: $16 for 5-pack replacement bags
Success Rate: 42%
Difficulty: Easy

💡 Yeedi Quirk: Vac 2 Pro's bag sensor triggers at 70% full (not 100%). This prevents overfilling but means you replace bags earlier than competitors. It's intentional for suction performance.

If This Doesn't Work: Try Fix 2 - charging dock power cycle

---

Fix 2: Won't Connect to Wi-Fi - Reset Network Settings (Works 24% of Time)

Why This Helps: Yeedi vacuums connect only to 2.4GHz Wi-Fi (not 5GHz). If your router broadcasts both, it can confuse pairing.

Symptoms:

• Yeedi app says "Device Offline"
• Can't add robot during setup
• Wi-Fi light blinks blue rapidly during pairing then goes solid red
• Worked fine then suddenly disconnected

How to Fix:

1. Confirm 2.4GHz network - Check router settings - Yeedi ONLY works on 2.4GHz band
2. Check password length - Wi-Fi password must be under 32 characters (Yeedi limitation)
3. Move close to router - For pairing, place robot within 10 feet of router
4. Reset Yeedi Wi-Fi - Press and hold BOTH dock and spot clean buttons for 5 seconds
5. Wait for voice - Robot says "Wi-Fi reset successful" in English
6. Re-pair in app - Open Yeedi app → Add Device → follow prompts exactly
7. Use correct pairing mode - When app asks to blink Wi-Fi light, it should blink BLUE (not red)

Time: 8 minutes
Cost: Free
Success Rate: 24%
Difficulty: Easy

⚠️ Important: Yeedi Vac 2 Pro does NOT support WPA3 security (only WPA2). If your router uses WPA3, create a "guest network" with WPA2 for the Yeedi.

If This Doesn't Work: Try Fix 3 - charging contact cleaning

---

Fix 3: Won't Charge on Station - Clean Contacts and Alignment (Works 18% of Time)

Why Yeedi-Specific: Vac 2 Pro + auto-empty station uses FOUR charging contacts (two for power, two for data). All four must connect or charging fails.

Symptoms:

• Docks perfectly but charging light doesn't turn on
• Station auto-empties but robot won't charge
• Robot charges for 10 seconds then stops
• Charging indicator blinks red slowly

How to Fix:

1. Inspect robot contacts - On robot underside: four gold-plated pins in a row
2. Clean robot pins - Wipe all four pins with dry microfiber cloth firmly
3. Inspect station contacts - On station docking area: four spring-loaded pins
4. Clean station pins - Use dry cloth, press each pin in while wiping
5. Check alignment marks - Triangle mark on robot should align with triangle on station
6. Test manual docking - Place robot on station by hand - contacts should meet exactly
7. Check for bent pins - If any station pin bent, gently straighten with pliers
8. Run charging test - Should see blue charging light within 3 seconds of docking

Time: 6 minutes
Cost: Free
Success Rate: 18%
Difficulty: Easy

💡 Pro Tip: Yeedi's four-contact system is more reliable than two-contact systems WHEN clean. But it also means four points of failure. Weekly cleaning prevents 95% of charging issues.

If This Doesn't Work: Try Fix 4 - 3D sensor calibration

Fix 4: 3D Obstacle Avoidance Not Working - Calibrate Sensor (Works 12% of Time)

Why Yeedi-Specific: Vac 2 Pro uses a structured light 3D sensor on the front. If miscalibrated, it bumps into objects it should avoid.

Symptoms:

• Crashes into chair legs it used to avoid
• Bumps furniture repeatedly
• Doesn't detect dark/black objects
• Obstacle avoidance worked when new, degraded over time

How to Fix:

1. Clean 3D sensor lens - On front bumper, black rectangular lens - wipe with microfiber cloth
2. Check for scratches - Deep scratches on lens ruin 3D detection permanently
3. Run calibration - Yeedi app → Settings → Obstacle Avoidance → Calibrate
4. Calibration process - Robot spins 360°, projects light patterns - takes 30 seconds
5. Test environment - Place common objects (shoes, cords, pet bowl) on floor
6. Run test clean - Start cleaning cycle, watch if robot avoids test objects
7. Adjust sensitivity - In app: Obstacle Avoidance Sensitivity → Set to "High"

Time: 7 minutes
Cost: Free
Success Rate: 12%
Difficulty: Easy

⚠️ Limitation: Yeedi's 3D sensor doesn't work in complete darkness (needs some ambient light). It also struggles with transparent objects (glass, clear plastic). This is normal for structured light systems.

If This Doesn't Work: Try Fix 5 - brush roller jam

---

Fix 5: Weak Suction or Strange Noise - Clear Roller Jam (Works 8% of Time)

Why Common with Yeedi: Vac 2 Pro's floating roller brush can trap large debris between roller and housing, causing grinding sounds.

Symptoms:

• Loud grinding or rattling from bottom
• Suction works but makes terrible noise
• Robot stops mid-clean with error beep
• Performance fine on hard floors, struggles on carpet

How to Fix:

1. Power off robot - Use power button (not app remote)
2. Flip over - Place on soft towel
3. Open roller cover - Press two green release tabs, lift cover off
4. Remove roller - Lift floating roller brush straight up
5. Check for large debris - Look for coins, twist ties, large chunks stuck in cavity
6. Clean roller ends - Hair wraps around the hexagonal end caps - cut and remove
7. Check roller bearing - Spin roller in your hand - should rotate smoothly, not grinding
8. Reinstall - Roller has flat side and curved side - flat side faces down
9. Test suction - Power on, should hear strong suction immediately

Time: 6 minutes
Cost: Free (replacement roller: $18)
Success Rate: 8%
Difficulty: Easy

💡 Yeedi Design: The floating roller adjusts height automatically for different floor types. Don't force it down when reinstalling - it should sit loosely and "float" naturally.

If This Doesn't Work: Check Fix 6 - error code reference

Prevent Future Problems

Keep Yeedi Vac 2 Pro running 3-5 years:

• 🔧 After Every Use: Check dustbin even with auto-empty (hair can clog inlet)
• 🔧 Weekly: Wipe all four charging contacts on robot and station
• 🔧 Every 2 Weeks: Clean 3D sensor lens with microfiber cloth
• 🔧 Monthly: Replace auto-empty dust bag (even if not full light - extends motor life)
• 🔧 Every 3 Months: Remove and wash dustbin and filter with water, dry 24 hours
• 🔧 Every 6 Months: Check wheel bearings - should spin freely without grinding

Pro Tip: Yeedi's auto-empty station motor lasts longer if you replace bags at 70% full (when light blinks) rather than waiting until completely packed.

Common Questions

How often should I replace the Yeedi auto-empty dust bag?

With daily use in a 1,500 sq ft home: every 3-4 weeks. With every-other-day use: 5-6 weeks. The blue "bag full" light triggers at 70% capacity. Replace bags when light blinks to prevent strain on the auto-empty motor.

Why does my Yeedi Vac 2 Pro keep saying it's offline in the app?

Most common causes: (1) Robot connected to 5GHz Wi-Fi instead of 2.4GHz, (2) Router uses WPA3 security (Yeedi only supports WPA2), (3) Wi-Fi password changed and robot not updated, (4) Router firmware update changed settings. Reset Wi-Fi and re-pair.

Can I use Yeedi Vac 2 Pro without the auto-empty station?

Yes. Place robot on any flat surface with the charging dock nearby. It will charge and work normally. Auto-empty is optional - robot has standard 400ml dustbin you can manually empty. But you lose the main convenience feature.

How do I know if my Yeedi battery needs replacement?

Test: Fully charge robot overnight (4-6 hours). Start cleaning on medium suction. Time how long it runs before returning to dock. New battery: 150+ minutes. Aging battery (1-2 years): 90-120 minutes. Replace when: under 60 minutes runtime.

Is the Yeedi Vac 2 Pro good for pet hair?

Yes, excellent for pet hair. The floating roller and strong suction (3000Pa) handle pet hair well. Auto-empty station means you're not touching hair when emptying. Only limitation: long hair (6+ inches) can wrap around roller - clean weekly.

What's the difference between Yeedi Vac 2 Pro and Vac Max?

Vac 2 Pro: 3000Pa suction, 3D obstacle avoidance, auto-empty station. Vac Max: 3000Pa suction, NO 3D sensor (uses standard bump navigation), can add auto-empty station separately. Vac 2 Pro has smarter navigation but costs $100 more.
