Vacuum makes loud high‑pitched whistling noise during use

Safety first: Turn OFF and remove the battery before inspecting seals.

• Step 1 – Check dust bin seating: Remove and reinstall the dust bin, ensuring it locks fully. Inspect the rubber gasket around the bin and cyclone for tears or deformation.
• Step 2 – Inspect wand and joints: Look for cracks in the wand and ensure all joints click firmly together.
• Step 3 – Listen for leak location: With the unit running, carefully move your ear (or a piece of tubing) around joints to locate the loudest whistle. Do not place hair or clothing near the brushroll.

Replace damaged gaskets, dust bin, or wand sections as needed to restore a proper seal.
