Severity: Warning — robot pauses; the corner brush won't spin until cleaned S5S6S7S8Q
Last verified: 2026-07-05 Tools: Phillips screwdriver Time: ~5 min Difficulty: easy

DIRECT ANSWER

Error 6 means the side brush is tangled and can't rotate. Hair winds up underneath the brush arm where you can't see it. Unscrew the brush, clear the shaft, and screw it back on.

COMMON CAUSES · RANKED

1

Hair wound under the brush MOST COMMON

Hair collects between the brush base and the robot body, out of sight until you remove the screw.

2

String or cable caught in the arms

Shoelaces, charging cables and curtain cords tangle in the three brush arms mid-clean.

3

Bent or damaged brush UNCOMMON

A brush with twisted arms drags against the body and stalls. Replacement is cheap and takes one screw.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Unscrew the side brush

One Phillips screw holds it. Keep the screw somewhere safe.

Clean the shaft and housing

Pull off every strand of hair around the spindle and wipe the mount area.

Refit or replace

Screw the brush back on — or fit a new one if the arms are deformed — and restart.
