My robot says "there is a problem with my charger". I've tried cleaning the contacts using rubbing alcohol but this did not solve the problem. It does not seem to take a charge. How can it be fixed?
Are the contacts on the base still springy?
Can you test the voltage between the contacts on the base?
I changed the location of the base station and for some reason that seemed to do the trick. Thank you for your quick response.👍
