You’ll also discover how Narwal’s advanced models, including the Freo Z Ultra and Flow, use LiDAR and AI navigation to return home reliably.
By the end, you’ll know exactly how to prevent docking failures and keep your robot vacuum returning to base every single time.
Why Your Robot Vacuum Can’t Find Its Dock(Including Roborock , Shark, and More)
Your robot vacuum’s dock is its home base — where it recharges and resets for the next cleaning cycle. But sometimes, even smart models like Roborock or Shark can’t find their dock. Below are the most common reasons this happens.
Low or Weak Battery
If the battery runs out before the vacuum finishes cleaning, it may stop midway and fail to return to the dock. Older batteries often cause this issue, especially in heavily used Roborock or Shark models.
Weak or Lost Connection
Some vacuums rely on Wi-Fi or infrared signals to locate the dock. When that connection drops, the robot may wander aimlessly instead of heading home.
Obstacles Around the Dock
Cables, furniture, or clutter can block the robot’s path. When the dock isn’t easy to reach or clearly visible, the vacuum may keep circling or stop nearby without docking.
Poor Dock Placement
If the dock is placed in a corner, under furniture, or too close to walls, the vacuum might not detect it properly. A tight or hidden spot often confuses navigation systems.
Dirty Sensors
Dust or hair on sensors can stop the robot from recognizing its surroundings or the dock. This is a common issue across brands like Roborock, Shark, and Roomba.
Software or Map Errors
Navigation glitches or outdated firmware can cause “can’t find dock” or “positioning failed” messages. A software error makes the robot think the dock is in the wrong place.
Lighting and Environment
For robots that use cameras or visual sensors, poor lighting or reflective floors can interfere with docking accuracy. LiDAR-based models like Narwal Flow are less affected by light conditions.
By knowing these common reasons, you’ll better understand why your robot vacuum misses its dock — and be ready to troubleshoot in the next section.
How to Fix a Robot Vacuum That Won’t Return to Its Dock
If your Narwal or other robot vacuum can’t find its dock or stops short of returning home, don’t worry — it’s usually an easy fix. Follow these steps to identify and resolve the most common causes of robot vacuum not returning to base problems.
-
Check the docking station placement: Make sure the dock is against a flat wall with about 1.5 meters (5 feet) of open space on both sides. Avoid placing it near stairs, under furniture, or in corners where sensors may have trouble detecting it.
-
Clear the area around the dock: Remove any objects that might block the robot’s path, such as cords, shoes, or furniture legs. A clear and open space allows the vacuum to locate its base more easily.
-
Inspect the wheels and underside: Flip the robot over and check for tangled hair, threads, or debris stuck in the wheels or brushes. Obstructions can slow down or misdirect the robot during docking.
-
Check the battery level: A weak or drained battery can prevent the robot from completing its route back to the dock. Start each cleaning session with a fully charged battery to ensure enough power for docking.
-
Clean the sensors: Use a soft, dry cloth to gently wipe the sensors on the robot and the docking base. Pay special attention to the cliff and front sensors, as these are responsible for recognizing the dock’s signal.
-
Verify Wi-Fi connectivity: Some models rely on Wi-Fi for navigation or to communicate with the dock. If the signal is weak, move the router closer or restart your network before starting a new cleaning cycle.
-
Empty the dustbin and clean the brushes: A full dustbin or tangled brush can reduce navigation accuracy and cause the robot to stop early. Keep these parts clean for smooth operation and consistent docking.
-
Reset the navigation system: In the mobile app, reset or rebuild the current map. If your robot has a physical reset button, press and hold it for a few seconds to recalibrate its route memory.
-
Update the vacuum’s software: Open the app and check for firmware updates. Updated software often improves navigation and fixes docking-related errors.
-
Run a test cleaning cycle: After completing these checks, start a short cleaning session to see if the robot returns to the dock correctly. If it still struggles, repeat the steps or contact customer support for further assistance.
Most docking problems — whether you’re using a Narwal, Roborock, or Shark robot vacuum — can be resolved through these basic checks. Most robot vacuum issues can be traced back to simple causes like dock placement, sensor dust, or outdated firmware — all of which can be fixed in minutes.
Advanced Fixes: How to Solve Persistent Docking and Positioning Errors
If your robot vacuum still can’t find its dock after following the basic troubleshooting steps, a few deeper fixes may help. These advanced methods target system-level problems such as corrupted maps, firmware bugs, or sensor calibration errors that prevent docking.
Reset or Power Cycle the Robot and Dock
Restarting both the vacuum and the docking station can resolve temporary communication or navigation glitches. Turn off the robot, unplug the dock for about 30 seconds, then power both back on. This clears short-term memory conflicts and often restores docking functionality.
Update the Firmware or App Software
Outdated firmware can cause “can’t find dock” or navigation errors. Open your vacuum’s app and check for the latest software updates. Firmware updates typically improve path planning, sensor performance, and docking precision. Keeping your Narwal or Roborock device updated helps prevent recurring positioning problems.
Perform a Factory Reset (Last Resort)
If navigation issues persist, consider performing a factory reset. This restores the device to its original settings and clears any corrupted data. After the reset, rebuild your home map in the app and test whether the vacuum now returns to the dock normally. Always follow the brand’s official instructions — reset procedures vary by model.
Roborock Positioning Failed / Error 23 Fix Guide
Some Roborock users encounter messages such as “Positioning failed” or “Error 23”, which indicate mapping or sensor calibration errors.
These usually occur when:
-
The map data becomes corrupted during cleaning
-
The dock is moved without rebuilding the map
-
Dust covers the LiDAR or charging sensors
-
The firmware is outdated
To fix this:
-
Place the dock back in its original position.
-
Clean the LiDAR and dock sensors with a soft, dry cloth.
-
Open the Roborock app, delete the current map, and rebuild a new one.
-
Update to the latest firmware version.
-
Restart both the robot and the dock after updating.
If the issue persists, perform a factory reset and rebuild the map from scratch. This usually resolves long-term “positioning failed” errors by refreshing the robot’s internal navigation data.
