Use Case

This bottom plate is essential for owners of Eureka Airspeed and Boss uprights experiencing reduced suction, motor noise, or visible damage to the vacuum base. If your vacuum loses suction suddenly or the motor housing rattles, the bottom plate may have cracked or warped, allowing unfiltered air to bypass the motor. Replacing the bottom plate restores sealed operation, protects the motor from debris ingestion, and returns your vacuum to full cleaning power. Swiss Boy Vacuum's parts specialists can help diagnose motor chamber issues and source the correct replacement quickly.
