Robot vacuum says “Charging Error 8” and cannot charge at all.

Safety first: Unplug the Home Base before inspecting it. Do not open the base if you are not qualified.

Steps to resolve:

• Check outlet: Plug another device into the same outlet to confirm it has power.
• Inspect power cord: Look for cuts, kinks, or damage to the Home Base power cord and adapter.
• Test with another base (if available): If you have access to another compatible Home Base, try charging the robot on it.

When to replace parts: If the outlet is good and the robot charges on another base, replace the Home Base. If it does not charge on any base, the robot’s internal charging circuit may be faulty.
