Use Case

This transmission assembly is essential for Sentria owners experiencing loss of brush roll power, weak motor engagement, or complete failure of the drive system. When the transmission wears out or fails, the vacuum's brush roll loses power, and the motor may struggle or stall. The PKA 552306 transmission assembly restores full drive function, allowing the motor to properly spin the brush roll for effective carpet cleaning and pet hair removal. Professional installation is recommended, and Swiss Boy Vacuum's technicians can diagnose transmission issues and perform replacement service at our Bountiful shop.
