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?
Manually placing the Roomba on the base will make it charge for a split second then it stops. Maybe there is minor unevenness. I’ll move it to another wall but without rearranging all my furniture there’s really only one spot for it to go.
