The battery-powered carpet cleaner has a very short runtime even after a full charge.

Safety first: Remove the battery pack before inspection.

• Confirm charge: Charge the battery fully using the official charger until indicators show a full charge.
• Test in different modes: Compare runtime in normal vs. boost modes. Very short runtime in all modes indicates battery wear.
• Replace battery: Install a genuine replacement battery compatible with your model.
• Battery care: Avoid storing the machine fully discharged and keep it in a cool, dry place to extend battery life.
