Cordless SEBO vacuum runs for only a few minutes on a full charge before shutting off.

Safety first: Do not continue to run the battery to complete shutdown repeatedly; this accelerates damage.

• Verify full charge: Charge the battery until the charger indicates full. Ensure it remains on the charger for an extra 30–60 minutes to top-balance cells.
• Test on lowest power: Run the vacuum on the lowest suction setting and time the runtime. If it is still far below the specification, the battery capacity is degraded.
• Check for overheating: If the battery or vacuum becomes very hot during the short runtime, the pack may have internal resistance issues and should be replaced.
• Replace battery: Purchase a genuine SEBO replacement battery pack. Battery packs are not user-repairable and should not be opened.
