Product Description

The Hoover GS-4478-6 carbon brush assembly is a critical replacement component designed for Hoover's high-performance GS-series central vacuum motors.

Carbon brushes are wear items that naturally degrade with motor use. Worn brushes reduce motor efficiency, increase noise, and can lead to motor failure. These genuine Hoover brushes are engineered to OEM specifications for reliable fit and function across compatible GS motor installations.

Compatible with Hoover GS-series central vacuum power units found in WindTunnel, Max, React, and commercial Conquest and Hushtone systems throughout the Wasatch Front.
