COMMON CAUSES · RANKED

1

Debris wedged behind the bumper MOST COMMON

Grit and small objects slip into the gap behind the bumper and hold it compressed — eufy's first instruction is to tap it loose.

2

Angled collision jammed the bumper

The L70 article notes the error typically appears after hitting walls or furniture at an angle, which wedges the bumper sideways.

3

Shipping protector never removed UNCOMMON

On a brand-new robot, eufy says to check that the foam shipping protector around the bumper was removed before first use.

4

Bumper misaligned after a hard hit RARE

If the bumper sits asymmetrically, eufy's guidance is to loosen its screws and reseat it — a service case if that fails.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Tap the bumper clean

With your palm, tap the front bumper repeatedly along its length so any dust or debris trapped underneath falls out.

Test the spring action

Press the bumper in and release it on both sides — it must snap back instantly with no sticking point.

Move the robot and restart

Set the robot down in a new position on open floor and start the clean again.

Reset if the error persists

eufy's L70 procedure ends with a factory reset; if Error 1 still returns, contact eufy support at [email protected].
