Every pad you run goes through a driver, so the driver's condition affects every cleaning cycle. It clamps the pad, transmits torque to it, and keeps it running flat against the floor. When any of those three goes, the pad's still spinning — it's just not doing its job right, and you're paying pad prices for polishing prices.
This is the genuine Nilfisk Advance OEM PAD DRIVER ASSY-20 RIGID, part number 56393650, brand new in the box. Check drivers when you change pads: any cracks, warping, or worn grippers means it's time. Cheap insurance against pads that go flying and floors that don't come clean.
Genuine OEM drivers are matched to the machine's drive shaft and torque output. That's why they last as long as they do.
