Vacuum is unusually loud with a high-pitched whistling sound

Safety: Remove the battery before inspecting seals.

• 1. Check bin seating: Remove and reinstall the dust container, ensuring it clicks firmly into place.
• 2. Inspect gaskets: Look for rubber seals around the bin, cyclone, and filter housing. Replace if torn, flattened, or missing.
• 3. Look for cracks: Examine the bin and cyclone for visible cracks that could cause air leaks.

Replacing worn seals or the dust container can restore proper suction and reduce noise.
