Possible Causes

Loose side brush, Worn side brush hub, Weak side brush motor, Loose motor connector

Safety: Turn off the robot.

Tighten brush: Ensure the side brush is firmly screwed onto the shaft.
Inspect hub: Check for cracks or rounding in the brush hub that could cause slipping.
Test motor: With the robot running, gently touch the side brush; if it stops easily, the motor may be weak.
If intermittent continues: Replace the side brush and, if needed, the side brush motor module.
