3 Things to Check When Your Robot Vacuum Stops Charging Early

Clean the charging contacts Dust and grime on the robot’s contacts or the dock’s pins are the most common cause. Wipe them with a dry cloth or a q-tip with rubbing alcohol.

Inspect the dock’s charging pins Make sure the pins aren’t worn down or bent. Damaged pins won’t make proper contact.

Replace the battery if needed Robot vacuum batteries last 2-3 years. If cleaning doesn’t help, a replacement is cheap and easy—often cheaper than a new machine.
