COMMON CAUSES · RANKED

Transient software glitch MOST COMMON

The firmware caught and cleared an internal fault on its own. No action needed for a single occurrence.

Corrupted Smart Map data UNCOMMON

A damaged map version can throw error 15 on every job until you revert to a good copy.

HOW TO FIX IT

SAFETY · READ THIS FIRST

Power off and remove the battery only for the battery-reseat step, and keep fingers off the metal contacts.

Press CLEAN and carry on

For a first occurrence, just restart the mission. Most robots never show error 15 twice.

Reboot if it repeats

Hold CLEAN until the light ring swirls white, then release. Boot-up can take a minute and a half.

Reseat the battery

Power off, remove the battery, wait ten seconds, and reinstall it. Test again.

Revert the Smart Map

In the app, open History, pick a Clean Map report from a good run, and choose Update Smart Map.
