Vacuum runs for only a few minutes on a full charge before shutting off.

Safety first: Remove the battery before inspection. Do not open the battery casing.

• Step 1 – Confirm full charge: Charge the battery until the Tower charger indicates full. Then immediately test run time on the lowest power setting.
• Step 2 – Compare to spec: Check your user manual for expected run time. If actual run time is less than half of specified, the battery is likely worn.
• Step 3 – Optimise usage: Use lower power modes for regular cleaning and reserve turbo for short bursts to extend battery life.
• Step 4 – Replace battery: Purchase a genuine Tower replacement lithium‑ion battery pack matching your model number and replace the old pack.
