The vacuum vibrates excessively, especially when using the floor head.

Safety first: Remove the battery before working on the floor head.

• Clean the brush roll thoroughly: Remove all hair and debris from the brush roll, especially from one side, to avoid imbalance.
• Inspect the brush roll: Check for missing sections of bristles or a visibly bent shaft. Replace the brush roll if damaged.
• Check floor head wheels: Remove hair and threads from the side wheels of the floor head.
• Test without the floor head: Run the vacuum with only the wand attached. If vibration disappears, the floor head is the source and should be repaired or replaced.
