THE PROBLEM
We have received a small number of reports of issues with the Charger that comes with
Roomba. These broadly break down into the following categories:
Charge Indicator Light on the Charger does not illuminate.
Charge Indicator Light on the Charger does not go out after 12 to 14 hours.
This issue has been tracked down and the charging circuitry improved to eliminate the
possibility of this failure mode as of 10/25/02.
DIAGNOSIS
If the Indicator Light on the Charger does not illuminate when the Charger is
plugged in, the following should be checked:
1. Ensure AC Adapter is plugged into a working outlet. Try several outlets to be
sure.
2. Ensure AC Adapter is fully plugged into the Charger. No metal (or almost
none) should be visible once the plug is fully inserted.
3. Ensure that the Charge Plug is fully inserted into Roomba. The Charge Plug
will only fit into socket in the proper orientation.
4. Ensure that the Battery Pack is properly inserted. To be sure, remove it,
inspect the contacts both in the Battery Pack and in Roomba to make sure that
they are not blocked by dirt, and reinsert the Battery Pack. It should click into
place on each side.
5. Remove the Charge Plug and turn Roomba on. If the room size lights do not
illuminate and there is no other activity, the Battery Pack might be defective.
If the Indicator Light on the Charger does not go out, ensure that customer is
aware that the 12-14 hour timer restarts every time any of the following happens:
o Charger is plugged in
o AC Adapter is unplugged from an outlet wall or the AC Adapter is
unplugged from the Charger.
o Power failures, brownouts, and dips can also cause the timing cycle to start
again.
If the Charger gets too hot to touch it should be unplugged. A replacement Charger should
be obtained.
NOTE: No lights will be illuminated on Roomba when it is charging!
