Shark robot not returning to the dock
DIRECT ANSWER
COMMON CAUSES · RANKED
Dock without clearance MOST COMMON
Furniture, cables or rugs crowding the dock block the robot's final approach line.
Dock moved after mapping
Mapping robots return to where the dock used to be; a relocated base means a lost robot until the map updates.
Mission started away from the dock
Cleans launched from the middle of a room leave the robot without a mapped route home — the "cannot find dock" state in Shark's manuals.
Dirty sensors or dock contacts UNCOMMON
Dusty navigation sensors and oxidized charging strips make the robot circle the dock without ever latching on.
HOW TO FIX IT
Reposition the dock
Put the dock flat against a wall on hard, level floor, with about a metre clear on each side and nothing in front.
Clean contacts and sensors
Wipe the dock strips, the robot's underside contacts and its sensor windows with a dry cloth.
Start missions from the dock
Always launch cleaning with the robot docked so its map keeps a valid return path — and remap after moving the dock.
Watch one return trip
Send the robot home from a room away and watch where it fails — circling the dock points at sensors, stopping short points at the map.

Charging dock — AI robots
Wipe the two metal charging strips with a dry cloth before blaming the dock; give it a metre of clearance each side so the robot can line up.
