This Advance pad driver is designed to be used with the Advance SC401 floor scrubber and can secure any 17" scrubbing pads, stripping pads or even polishing pads. This bristled pad holder comes with a locking device to both secure your pad as well as keep it centered during scrubbing. Do not use the pad driver without any floor pad. The pad driver is not a scrubbing brush and will scratch your floor. For other floor scrubber accessories, check out our hard floor supplies and accessories area for all the options we carry.
