Vacuum makes grinding or rattling noise from the floor nozzle when brushroll is engaged

Safety first: Remove the battery before opening the nozzle.

• Step 1 – Remove brushroll: Open the nozzle cover and take out the brushroll.
• Step 2 – Inspect end caps: Remove any removable end caps and clean out hair and debris. Check for cracks or melted plastic.
• Step 3 – Spin test: Spin the brushroll shaft and end caps by hand. Any grinding or roughness indicates bearing failure.
• Step 4 – Check gears (if accessible): On some Dirt Devil heads, gears are visible under a side cover. Inspect for missing teeth or debris.
• Step 5 – Replace assembly: Replace the brushroll or entire motorized nozzle if internal gears are damaged.
