How to Clean Roomba Charging Contacts for Optimal Performance
To clean Roomba charging contacts, first, unplug the charger and remove the Roomba’s battery. Then, use a soft dry cloth or a cotton swab to gently wipe the metal contacts on both the Roomba and charger. If there is visible dirt or grime, a microfiber cloth slightly dampened with rubbing alcohol may be used. Finally, wait for the contacts to dry completely and reassemble the Roomba before charging it again.
