Safety first: Turn OFF and remove the battery before working on the mini brush.

Clean brushroll: Open the mini brush housing and remove hair and fibers from the brushroll and end caps.
Check rotation: Spin the brushroll by hand; it should move freely.
Inspect connector: Ensure the mini brush is fully inserted into the handheld unit and that contacts are clean.
Replace mini brush: If the motor is weak or stalls easily after cleaning, replace the mini motorized brush with a new Sencor accessory.
