The Beam/Electrolux 35-foot Alliance Interface Central Vacuum Hose (Part 050929A) is the genuine OEM electric hose for Beam Alliance central vacuum systems, providing the 2-way communication link between the hose handle and the Alliance power unit that makes variable speed suction control possible. This is the correct 35-foot replacement hose for any Beam Alliance system installation - not a generic or compatible substitute, but the hose designed specifically by Beam to unlock the full capability of your Alliance power unit.

The Alliance hose features an ergonomic soft-grip open-loop handle that provides a comfortable, fatigue-reducing grip during extended cleaning sessions. The kink-resistant hose body minimizes tangling and maintains consistent airflow even when the hose is pulled around tight corners and furniture. The handle's slide-style speed control allows you to increase or decrease suction electronically - a feature exclusive to Beam Alliance power units and not available with standard Beam hoses or power units.

Part 050929A is available in pigtail and direct connect configurations to suit your inlet valve type. As with all Alliance interface hoses, it requires a compatible Beam Alliance power unit to enable variable speed communication. Used with a non-Alliance Beam power unit, the hose functions as a standard on/off electric hose but the variable speed feature will not be active. Swiss Boy carries both 30-foot (050928A) and 35-foot versions - the 35-foot model is the correct choice for larger rooms.

Swiss Boy Vacuum is an authorized Beam Alliance dealer and stocks genuine Alliance hoses including the 050929A. If you are unsure whether your Beam system is Alliance-capable, or if you need to verify whether this hose is compatible with your power unit and inlet valve, our team can help you identify your system and confirm the correct parts. Using a genuine Beam Alliance hose ensures the communication electronics in your system work correctly.
