Model issues and repair guidance
For a commercial-width floor pass, first decide whether the complaint is airflow, sealing, or rolling resistance. Strong suction at the bare pipe with weak pickup at every point across the mouth calls for neck and channel clearing; loss at one edge calls for insert or body alignment. Fit brush strips for dry debris and rubber blades for liquid. If push effort rises without a suction change, inspect rear wheels, axles, strip pressure, and neck movement.Separate airflow, sealing, and rolling resistance. Whole-width loss with good pipe suction points to neck or channel; one-edge loss points to insert alignment. Match brushes or blades to the task, and inspect wheels, axles, strip pressure, and neck for heavy push.
