Robot vacuum battery drains quickly, and runtime is much shorter than when new.

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

• Measure runtime: Fully charge the robot, then run it until it returns to the dock or shuts off. If runtime is less than 50% of the original, the battery is worn.
• Reduce load: Clean filters and brushes to reduce power draw.
• Replace battery: Install a new, genuine Hoover robot vacuum lithium battery pack.
• Battery care: Avoid storing the robot fully discharged, and keep it on the dock when not in use.
