Lower Base Assembly - Eureka/Beam Power Nozzle with Switch CH50400 Wire the new assembly toThis replacement lower base assembly with switch fits Eureka, Sanitaire, and Beam power nozzles. The base houses the brush roll and sets the cleaning height, and the integrated switch controls power to the nozzle motor. When the base cracks or the brush roll stops spinning or runs noisily, cleaning suffers and the nozzle can sit unevenly on the carpet. A sound lower base restores the correct height, a solid brush roll mount, and working power control.
