Fix 1: Optimize Dock Placement and Clearance (Works 42% of Time)

Why This First: Roborock uses infrared and LiDAR to locate dock. Obstacles, walls, or furniture blocking the area prevent successful docking.

Symptoms:

• Roborock gets close to dock but can't align
• Robot circles near dock repeatedly
• Works sometimes but fails other times
• Recently moved dock or furniture near dock

How to Fix:

Step 1 - Check Current Dock Placement:

1. Measure clearance around dock:
   • Left side: 0.5 meters (20 inches) minimum
   • Right side: 0.5 meters (20 inches) minimum
   • Front: 1.5 meters (5 feet) minimum
   • Back: Against wall is OK
2. Check for obstacles:
   • Furniture legs near dock
   • Cables or cords in front of dock
   • Rugs with tassels near dock area
   • Reflective surfaces (mirrors, glass) nearby

Step 2 - Relocate Dock (If Needed):

1. Ideal Dock Location:
   • Against solid wall (not glass)
   • On hard, flat floor (not carpet)
   • Away from stairs or drop-offs
   • In area robot cleans regularly (not isolated room)
   • Away from direct sunlight (can interfere with sensors)
2. Plug in dock at new location
3. Wait for dock lights to turn on (usually green or white)

Step 3 - Test Manual Docking:

1. Carry Roborock to dock
2. Place directly on dock (charging should start)
3. Let charge for 2 minutes
4. Press "Clean" to start cycle
5. After 1-2 minutes, press "Home" button
6. Roborock should return directly to dock
7. If successful, dock location is good

Time: 5-10 minutes
Cost: Free
Success Rate: 42%
Difficulty: Easy

💡 Pro Tip: Roborock "remembers" dock location using LiDAR map. If you move dock, always do a manual dock first so robot updates dock position in map.

Optimal Dock Placement Examples:

• ✅ Living room corner, against wall, no furniture within 0.5m
• ✅ Hallway against wall, clear path from main rooms
• ✅ Kitchen against solid wall, away from appliances

Poor Dock Placement Examples:

• ❌ Between couch and wall (too tight)
• ❌ Under furniture overhang
• ❌ On thick carpet or rug
• ❌ Near floor-to-ceiling windows (sunlight interferes with sensors)

If This Doesn't Work: Try Fix 2 - clean dock and robot sensors

Fix 2: Clean Dock Infrared Sensors (Works 28% of Time)

Why This Helps: Roborock dock emits infrared signal that robot detects to align for docking. Dusty sensors = weak signal = docking failure.

Symptoms:

• Roborock gets within 1 meter of dock then loses it
• Robot circles in front of dock but won't align
• Docking worked fine, gradually got worse
• Recently cleaned very dusty areas

How to Fix:

Step 1 - Locate Dock Sensors:

1. Look at front of charging dock
2. Find small dark circles or rectangles (usually 2 sensors)
3. Located on either side of charging pins
4. May be recessed slightly into dock housing

Step 2 - Clean Dock Sensors:

1. Unplug dock from power
2. Use dry microfiber cloth to wipe sensors
3. For stubborn buildup: cotton swab with 70% rubbing alcohol
4. Don't press hard - sensors are delicate
5. Let dry 2 minutes if using alcohol
6. Plug dock back in

Step 3 - Clean Robot Dock Sensor:

1. Flip Roborock over or look at front bumper
2. Locate dock sensor (usually center of bumper, small dark window)
3. Wipe with dry cloth
4. Check for scratches or damage
5. Should be clear, not cloudy or dirty

Step 4 - Test Docking:

1. Place Roborock 1 meter from dock, facing dock
2. Press "Home" button on robot or in app
3. Robot should drive straight to dock and align perfectly
4. If successful, sensors were the issue

Time: 5 minutes
Cost: Free
Success Rate: 28%
Difficulty: Easy

💡 Note: Clean dock sensors monthly as preventive maintenance. Takes 30 seconds, prevents 90% of docking issues.

Prevent Docking Issues

Simple habits that ensure reliable docking:

• 🔧 Keep Dock Area Clear: 1.5m front, 0.5m sides permanently clear
• 🔧 Weekly: Clean dock sensors (30 seconds)
• 🔧 Monthly: Verify dock placement hasn't shifted
• 🔧 After Moving Furniture: Do manual dock to update robot
• 🔧 After Moving Dock: Always manual dock first, then test auto-dock
• 🔧 Keep Firmware Updated: Enable auto-update in app settings

Pro Tip: Create a "dock zone" - tape off or mark the floor around dock. Helps family members remember not to put things near dock.

Avoid These Mistakes:

• ❌ Putting dock in tight corner with minimal clearance
• ❌ Moving dock without manual docking after
• ❌ Placing dock on thick carpet (causes alignment issues)
• ❌ Putting dock near windows with direct sunlight (interferes with infrared)
• ❌ Creating no-go zones that accidentally block dock access

Common Questions

Why does my Roborock find the dock sometimes but not others?

Inconsistent docking usually means insufficient clearance around dock or dirty sensors. Something (furniture, person, pet) occasionally blocks the path or sensor signal. Ensure permanent 1.5m clearance in front of dock and clean sensors monthly.

Can I move the dock to a different room?

Yes, but you MUST manually dock the robot after moving. Place Roborock on dock, let it charge 2 minutes, then start a cleaning cycle. Robot will update dock location in its map automatically.

My Roborock says "Cannot find dock" but it's right there - why?

Dock sensors are dirty, dock isn't powered on, or map shows dock in wrong location. Check: (1) Dock power light is on, (2) Clean dock infrared sensors, (3) Manually dock robot to reset dock position.

Does Roborock need Wi-Fi to find the dock?

No. Roborock uses LiDAR (laser navigation) and infrared sensors to locate dock - no Wi-Fi needed for docking. Wi-Fi only needed for app control and remote commands.

How close does Roborock need to be to detect the dock?

Infrared dock sensors have 3-5 meter range. Roborock uses LiDAR map to navigate to general dock area (within 5 meters), then infrared for final alignment. If robot can't get within 5 meters due to obstacles, docking fails.

Should the dock be against a wall?

Yes, back of dock should be against solid wall. This provides stability and prevents dock from shifting. Don't place against glass walls or windows - reflections interfere with sensors.

Can I use a third-party charging dock?

Not recommended. Third-party docks often have incorrect sensor placement or weak infrared signal, causing docking failures. Roborock OEM docks are model-specific - use the dock that came with your robot.
