Fix 2: Verify Dock Power and Placement (Works 22% of Time)

Why This Helps: Eufy charging bases need stable power and proper surface contact. Uneven surfaces or loose power connections prevent charging.

Symptoms:

• Dock has no indicator lights at all
• RoboVac docks successfully but never charges
• Charging works if you press RoboVac down on dock
• Recently moved dock to new location

How to Fix:

Step 1 - Check Dock Power:

1. Look at charging base - should have indicator light (usually green or blue)
2. If no light:
   • Check power adapter fully plugged into dock
   • Check adapter plugged into wall outlet
   • Try different wall outlet
   • Inspect adapter cord for damage
3. Power adapter should output 19V (check adapter label)

Step 2 - Optimize Dock Placement:

1. Surface Requirements:
   • Hard, flat surface (tile, hardwood, laminate)
   • If on carpet: place thin rigid board under dock
   • Surface must be level (use level tool if unsure)
2. Clearance Requirements:
   • 0.5 meters (20 inches) on each side
   • 1.5 meters (5 feet) in front of dock
   • Back against solid wall (not required but recommended)

Step 3 - Check Dock Stability:

1. Press down gently on dock - should not wobble
2. If wobbles: adjust feet or place on firmer surface
3. Dock movement during docking = poor contact

Step 4 - Test Manual Docking:

1. Place RoboVac on dock by hand
2. Push gently backward until it "clicks" into charging position
3. Charging light should illuminate immediately
4. If light only works with pressure, dock surface is uneven

Time: 5-10 minutes
Cost: Free (or $10 for board if on carpet)
Success Rate: 22%
Difficulty: Easy

⚠️ Important: Eufy 11S, 15C, 30C models have low-profile design - extra sensitive to uneven docking surfaces.

Prevent Future Charging Issues

Simple habits that prevent 85% of Eufy charging problems:

• 🔧 Weekly: Wipe charging contacts on RoboVac and dock (30 seconds)
• 🔧 After Heavy Cleaning: Check contacts immediately if cleaned dusty/pet areas
• 🔧 Monthly: Vacuum around dock area to prevent dust buildup
• 🔧 Keep Dock Stable: Don't move dock frequently, maintain clearances
• 🔧 Avoid Deep Discharge: Don't let battery drain to 0% repeatedly (shortens life)
• 🔧 Power Surge Protection: Use surge protector for charging dock

Pro Tip: Eufy 11S and 15C have exposed contacts - extra vulnerable to dust. If you have these models and carpets, clean contacts 2x per week.

Avoid These Mistakes:

• ❌ Using water to clean contacts (corrosion risk - use alcohol only)
• ❌ Forcing RoboVac onto dock (can bend contacts)
• ❌ Leaving RoboVac off charger for weeks (deep discharge damages battery)
• ❌ Using wrong voltage adapter (permanent battery/circuit damage)

Common Questions

Why does my Eufy charge for 5 minutes then stop?

Usually dirty or oxidized charging contacts causing intermittent connection. Clean both RoboVac and dock contacts with rubbing alcohol. Also check that dock is on perfectly flat surface - wobbling breaks contact.

Can I leave my Eufy RoboVac on the charger 24/7?

Yes. All Eufy models have smart charging that prevents overcharging. Leaving on dock 24/7 is recommended by Anker/Eufy. Battery lifespan is based on charge cycles (300-500 cycles), not time on charger.

My Eufy shows charging in app but battery doesn't increase - why?

Battery calibration issue or failing battery. Try full drain/recharge cycle: run until dead, charge uninterrupted for 8 hours. If still doesn't charge, battery needs replacement (typical after 2 years / 400+ cycles).

How do I know if my Eufy battery is dead?

Signs of dead battery: runtime less than 30 minutes on full charge, won't turn on when off dock, battery drains from 100% to 0% in under 15 minutes. If 2+ of these, battery replacement needed.

Do third-party charging docks work with Eufy RoboVac?

Some do, but quality varies widely. OEM docks guarantee compatibility. Third-party docks often have weaker IR signals or incorrect contact spacing. If buying third-party, verify your exact model is supported and read reviews carefully.

My Eufy 11S won't charge but Eufy 30C dock looks identical - are they compatible?

Most Eufy docks are model-specific despite looking similar. Contact placement and IR sensor frequency differ. Always use dock designed for your exact model, or verify compatibility before purchasing.

Why does charging work when I manually place RoboVac but not after auto-return?

Dock sensors dirty or RoboVac's docking sensor malfunctioning. Clean both dock IR sensors and RoboVac's front sensor. If still fails, recalibrate by doing manual dock, then test auto-return from 1 meter away.
