Numatic Mechanical Vibration / Bearing Wear

Cordless vacuum is very noisy or rattles during operation

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

Worn motor bearings, Debris in brush head, Loose internal components, Damaged fan in motor

Safety first: Remove the battery before inspection.

Check brush head: Remove the brush bar and clear debris. Run the vacuum briefly without the head to see if noise reduces.
Isolate source: If noise remains with no head or hose attached, it is likely from the motor or internal fan.
Check for loose parts: Gently shake the vacuum body (battery removed) and listen for loose components.

Persistent loud rattling or grinding usually indicates motor or fan damage and requires professional replacement.
