Robot vacuum reports E8 or a battery error; it may shut down quickly or refuse to start cleaning.

Safety first: Turn OFF the robot and remove it from the dock.

• Check battery level: Place the robot on the dock and allow it to charge for at least 4–6 hours. Confirm that the charging indicator behaves normally.
• Clean charging contacts: Wipe the robot's charging pads and the dock's metal contacts with a dry cloth. Lightly polish with isopropyl alcohol if oxidized.
• Inspect battery connection: Remove the bottom cover to access the battery compartment. Ensure the battery connector is firmly plugged into the main PCB and that there is no corrosion.
• Test runtime: After a full charge, start a cleaning cycle. If the robot shuts down within a few minutes and E8 reappears, the Battery Pack is likely worn out.
• Replace battery: Remove the old battery pack (usually secured with screws or a strap) and install a new, compatible Honiture Robot Vacuum Battery Pack with the same voltage and capacity rating.
