Main Brushroll Assembly
The most common source of pulsing is hair or debris wrapped tightly around the brushroll bearings. This increases the mechanical load on the drive motor, causing the control board to cycle power to prevent a total stall and motor burnout, which manifests as a rhythmic pulsing sound.

Drive Wheel Module
If the internal planetary gears within the drive wheel assembly are fouled or have a fractured tooth, the motor will encounter uneven resistance during each rotation. The logic board's feedback loop attempts to compensate for this uneven load, resulting in an audible surging or pulsing as the robot moves.

Side Brush Motor
A blockage or a failing gear in the side brush transmission can cause the small DC motor to struggle. Because these motors are sensitive to current fluctuations, the robot's firmware will pulse the power to the side brush in an attempt to clear the perceived obstruction.
