DIRECT ANSWER

Error 2 means the front bumper is stuck and no longer springs back. A pebble or cable end is usually jammed in the gap. Tap the bumper a few times, shake the debris out, and restart.

COMMON CAUSES · RANKED

1

Debris jammed in the bumper gap MOST COMMON

Gravel, pet food or a toy piece slips into the slot behind the bumper and holds it pressed.

2

Robot pinned against an obstacle

The robot drove tight under a kick plate or against a soft object that keeps the bumper compressed.

3

Bumper switch failure RARE

After a hard impact the microswitch behind the bumper can stay closed. If tapping never clears it, the switch needs service.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Tap the bumper repeatedly

Light, quick taps along the whole front edge usually shake loose whatever is jammed.

Check the gap

Press the bumper in and let go a few times. It should click back out instantly on both sides.

Move the robot and restart

If nothing falls out, carry the robot to a new spot and press the clean button again.
