Vacuum is unusually loud from the floor nozzle area, with a roaring or whistling sound.

Safety first: Turn OFF the vacuum and remove the battery pack before inspecting the nozzle.

• Inspect nozzle housing: Look for visible cracks or separation in the plastic housing. Flex the nozzle gently to see if gaps open.
• Check gasket at wand connection: Ensure the rubber gasket where the wand meets the nozzle is present and not torn. Replace the gasket or nozzle if damaged.
• Clear obstructions: Remove the nozzle and check for debris lodged in the neck or internal channels.
• Replace nozzle if cracked: A cracked housing will continue to leak air and be noisy. Replace the entire Tristar motorized floor nozzle assembly.
