Light House Troubleshooting o Complaint : Customer gets a new Service Roomba (models 535 and above) and the old Light Houses stop working properly. Solution : Have the customer remove all the Light House batteries and reinsert them (flushes Light House memory). Background : When a customer first uses their new Roomba, all new Light house within RF range will turn on. Then, as Roomba cleans for the first time it will get within infrared distance of the Light House and share its identifier # with the Light House. Result is that they are 'paired' and each Light House can only be controlled by its specific Roomba. Therefore, when a new strange service robot comes into the picture it is necessary to flush the Light House memory so it can be paired anew. o The user can confuse the Roomba by moving the lighthouse to another room during a clean cycle. Then issues come up when the Roomba actually wants to find the dock at the end of the clean cycle and it enters the wrong room. Another issue is when the user manually docks the Roomba to abort a clean cycle and the Roomba ignores the dock and even bumps into it because it thinks it is in another room. Solution : If accessories have been moved, turn robot OFF and then ON again. Also, have users not move accessories once a cycle has started. 31

Complaint : Customer gets a new Service Roomba (models 535 and above) and the old Light
Houses stop working properly. Solution : Have the customer remove all the Light House
batteries and reinsert them (flushes Light House memory). Background : When a customer first
uses their new Roomba, all new Light house within RF range will turn on. Then, as Roomba
cleans for the first time it will get within infrared distance of the Light House and share its
identifier # with the Light House. Result is that they are ‘paired’ and each Light House can

The user can confuse the Roomba by moving the lighthouse to another room during a clean
cycle. Then issues come up when the Roomba actually wants to find the dock at the end of the
clean cycle and it enters the wrong room. Another issue is when the user manually docks the
Roomba to abort a clean cycle and the Roomba ignores the dock and even bumps into it
because it thinks it is in another room. Solution : If accessories have been moved, turn robot
OFF and then ON again. Also, have users not move accessories once a cycle has started.
