Hi!
I require your help regarding a problem I’m encountering.
Hi,
I have an iRobot Roomba 4220. The battery won’t charge. I got a new battery and the Roomba worked fine until the battery died.Then I also got a new charger cord. Still won’t charge. After some research, it looks like I might have to buy and install a new mother board .
As an alternative, could I buy a charging device that I can just independently recharge the battery outside of the iRobot, and then just reinstall it each time to run it?
And where can I get one of those?
Thanks for any help on this issue.
Thank you so much in advance for your help!
