I'm in the process of cleaning up my shop and I came across this Roomba that was given to me a while ago, the guy who gave it to me said that he had bought 2 new battery packs for it, it would charge the first time, then after that it wouldn't charge the battery anymore.
So I started taking it apart this morning and man what a mess this thing is. It sounds like it was overcharging batteries to me, but has anyone else run into this with the roomba 4200 series?
Upgrade to ARC Pro
Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.
It was a nice little unit. I liked the color of it.
Just my 2 Cents.
