Robot Vacuum Won’t Return to Its Dock or Charge? Fixes

What is going wrong

• 1Dock powerConfirm the outlet is live and any switch on the cord is on before concluding anything about the robot.
• 2The contactsA thin film of dust on the pads is the most common reason a docked robot does not charge, and it looks like nothing.
• 3ClearanceMakers ask for about 1.5 ft each side and 4 ft in front because the machine needs room to line itself up, not because the dock needs the space.

Give the dock a reachable home

Robots find the dock by its short-range signal and by retracing their map, so placement matters more than owners expect. Manufacturers ask for clear space for a reason:

• Keep about 1.5 feet (0.5 m) clear on each side and about 4 feet (1.2 m) in front of the dock.
• Put the dock against a flat wall, not in a corner or behind a door.
• Leave it on a hard floor where possible; a thick rug at the dock makes docking alignment drift.
• Keep it in a mapped area the robot cleans, not a closed-off room.

Fix it in order

1. 1

   Wipe the charging contacts.

   Clean the metal pads on the dock and the matching pads on the robot with a dry cloth. A thin film of dust is the most common reason a docked robot does not charge.

2. 2

   Reseat the robot by hand.

   Place it on the dock manually and confirm the charge light comes on. If it charges by hand but not on its own, the problem is navigation back to the dock, not charging.

3. 3

   Power-cycle the dock.

   Unplug it for a minute and plug it back in. Confirm the outlet is live and any switch on the cord is on.

4. 4

   Shorten the return trip.

   If it runs out of charge before reaching the dock from far rooms, move the dock more central, or let it clean fewer rooms per run.

5. 5

   Re-map if the dock moved.

   If you relocated the dock, the robot may still drive to the old spot. Re-run mapping or setup so it learns the new location.
