Vacuum runtime is much shorter than specified, even on Eco/Normal mode.

Safety: Use only genuine or high‑quality compatible batteries rated for your Dyson model.

• Fully charge and test: Charge the battery to full, then time the runtime in Eco/Normal mode with a standard head.
• Compare to spec: If runtime is significantly below Dyson’s stated range (e.g., less than half), the battery is likely worn.
• Reduce load: Ensure filters are clean and airways clear to minimize current draw.
• Replace battery: Install a new genuine Dyson battery pack to restore runtime.
