Slow pulsing green LED while vacuum is running; suction seems reduced.

Safety first: Remove the battery before cleaning filters or the bin.

Steps to try:

• Check power setting: On models with a power selector, switch between normal and max modes. Confirm that the slow green pulse corresponds to eco mode.
• Clean filters: Remove and clean the pre‑motor and post‑motor filters as per the user manual. Allow them to dry fully before refitting.
• Fully charge battery: Place the battery on the original Gtech charger until the charge indicator shows full. Low charge can cause automatic power reduction.
• Inspect for blockages: Check the tube and floor head for partial blockages that can reduce suction even in eco mode.
