COMMON CAUSES · RANKED

1

Dirt over the dock's signal beacon MOST COMMON

The dock guides the robot in with infrared. A dusty or smeared emitter window makes the dock invisible.

2

Objects blocking the dock approach

Shoes and boxes in front of the dock break the robot's final approach line.

3

Dock moved mid-clean UNCOMMON

Relocating the dock while the robot is out orphans the position stored on its map.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Clean the dock's emitter window

Wipe the signal emission area on the dock's front with a dry cloth, and pick off any stickers or debris.

Clear the area around the dock

Leave about half a metre free on each side and 1.5 metres in front.

Keep the dock parked

Put it against a wall on hard floor and leave it there — every move forces the robot to relearn the spot.

Test the return

Start the robot a room away and press the dock button. It should drive back and connect without circling.
