Amazon Basics Mechanical Imbalance in Brush Roll or Motor Fan

The vacuum vibrates excessively or feels unbalanced in the hand.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Uneven debris on the brush roll, Bent brush roll shaft, Damaged motor fan blades, Foreign object stuck in the motor fan

Safety first: Turn OFF the vacuum, remove the battery, and detach the floor head.

Step-by-step checks:

1. Clean brush roll thoroughly: Remove all hair and debris from the brush roll. Even small clumps can cause imbalance.
2. Check brush roll straightness: Roll it on a flat surface; if it wobbles, it may be bent and should be replaced.
3. Test without floor head: Run the vacuum with only a small tool attached. If the vibration disappears, the issue is in the head. If it remains, the main motor fan may be damaged.

When to stop: If the vibration persists and seems to come from the main body, the motor assembly likely needs replacement.
