Display shows LOW or a flashing empty battery icon and vacuum shuts off

Safety first: Use only the original or Bissell-approved charger.

• Fully charge battery: Place the vacuum or battery on the charger until the indicator shows a full charge (steady light or full bars). This may take 3–4 hours depending on model.
• Avoid partial charges: Allow the battery to reach full charge regularly to help the fuel gauge calibrate.
• Use appropriate power mode: Reserve MAX/Turbo mode for short bursts. Continuous use on high power will significantly reduce runtime and trigger LOW sooner.
• Evaluate battery age: If runtime is much shorter than when new (e.g., only a few minutes), the battery cells may be worn out. Replace the battery pack.
• Check charger function: If the battery never reaches full indication, test with another charger or battery to determine whether the charger is faulty.
