Vacuum runs but there is a whistling noise from the handle or bin area.

Safety first: Remove the battery pack.

Check assembly:

• Remove and refit the dust bin, ensuring it clicks into place.
• Ensure the filter cover is fully closed and latched.

Inspect seals:

• Check O‑rings and gaskets around the bin and filter housing for damage. Replace if flattened or torn.

If a crack is found in the plastic housing, replace the affected housing or bin assembly.
