Frequently asked questions
Will this fit my floor machine even if it's not a Mercury?
The B/92 clutch plate is a widely used universal pattern, so this brush fits many machine brands built around a 17-inch, 92-clutch platform – confirm your machine's clutch type before ordering.
How is a stiff poly brush different from a bassine brush?
Stiff polypropylene bristles are built for aggressive scrubbing on tile, VCT and concrete, while bassine natural-fiber brushes are typically gentler and suited to burnishing or lighter buffing.
Does the brush come with the clutch plate installed?
Yes, the B/92 clutch plate ships pre-installed on the brush block, ready to mount.
How often should a scrub brush be replaced?
Replace it once bristles visibly shorten, splay, or stop lifting soil the way they did new – heavy daily use wears bristles faster than occasional use.
