I have a Roomba that has been having problems (after 3 months). The number provided in the manual for "customer care" is a recording about battery problems. This suggests a systemic problem with the battery - but worse, after three days of trying, I have not been able to talk to anyone. I put my phone on speaker while I worked and after 20 minutes, still no answer. I wish I had done a bit of research prior to buying this. My experience is that iRobot is after sales, and offers extremely poor (or zero) cutomer service.
