I’ve seen FAQs and troubleshooting pages that say clean the contacts with alcohol, and that works, but I seriously have to do that every time I run it. The only other thing that will work is jamming something under the Roomba to lean it onto the charging contacts. Is it a crappy base? Are there any diy tricks to give the base better contact?
I had a problem a few weeks ago where it wouldn’t charge and cleaning the contacts didn’t work for me. What did work is taking the bloody thing apart, removing and reinstalling the battery and cleaning things as I put it back together.
