Roborock Error 13 — Charging error

Severity: Warning — robot won't charge until dock and contacts make a clean connection S5S6S7S8Q
Last verified: 2026-07-05 Tools: dry cloth, isopropyl alcohol or eraser Time: ~10 min Difficulty: easy

DIRECT ANSWER

Error 13 means charging is failing — current isn't flowing between dock and robot. Dirty or corroded charging contacts cause most cases. Clean the metal strips on both, check the dock light, and retry.

COMMON CAUSES · RANKED

1

Dirty or corroded charging contacts MOST COMMON

Dust, mop moisture and oxidation build an insulating film on the contact strips. Roborock recommends alcohol or an eraser to cut through it.

2

Loose dock cable

The plug under the dock works itself loose. Roborock's own fix is to push the cable head in hard.

3

Dock power supply fault UNCOMMON

The dock light should be on with the robot off it, and off with the robot docked. Any other pattern points at the dock.

HOW TO FIX IT

SAFETY · READ THIS FIRST

Unplug the charging dock before wiping its contacts, and never use a dripping-wet cloth on them.

Clean both sets of contacts

Wipe the strips on the dock and under the robot with a cloth dampened in alcohol, or rub with an eraser to lift rust and stains.

Verify the dock light

Solid light with no robot, light off when docked — that is a healthy dock.

Reseat the dock cable

Push the cable head firmly into the slot on the underside of the dock.

Power-cycle the dock

Unplug the dock, wait two minutes, plug it back in, and dock the robot again.

Still failing? Try another outlet or dock

If a cleaned robot fails on a verified-good dock, the fault is inside the robot — contact support.
