Powr-Flite 18 inch Medium Grit Scrub Brush MG218M

The Powr-Flite MG218M scrub brush (part# MG218M) is an 18-inch medium-grit disc scrub brush for Powr-Flite 20-inch rotary floor machines. Medium grit is the middle option in the 18-inch brush family — more aggressive than a soft nylon brush but gentler than a hard-poly brush — so it handles everyday scrubbing on hard floors without the bite of a stripping brush. MG218M is the current Powr-Flite part number and replaces the older grit brushes PFLG18, PFMG18, PFHG18, PST18, PFMG19, PFHG19, PST19, and PST20.

Powr-Flite MG218M scrub brush — 18-inch medium-grit disc brush for 20-inch machines

Mounted on the drive block of a compatible 20-inch floor machine, the Powr-Flite MG218M scrub brush spins to scour ground-in soil and lift dirt from tile, sealed concrete, terrazzo, and other hard surfaces. Because it is a genuine Tacony/Powr-Flite part, it seats correctly on the machine’s drive hub and holds even scrub pressure across the full 18-inch face. The medium grit gives it enough cut for routine maintenance scrubbing and light prep work while staying friendly to sealed and finished floors that an aggressive stripping brush would chew up.

Installation is quick: with the machine unplugged, tip it back, line the brush’s lugs up with the drive block, and twist it into the lock so it seats fully before you lower the machine. A brush that is not seated square will hop and wear unevenly, so check that it sits flat before running it. Rotating to a fresh brush before the bristles are fully worn keeps scrub results consistent and protects the drive block.

Frequently Asked Questions

What does the Powr-Flite MG218M scrub brush do?

The Powr-Flite MG218M scrub brush (part# MG218M) is an 18-inch medium-grit disc scrub brush. The medium grit sits between a soft nylon brush and an aggressive hard-poly brush, making it a general-purpose scrubbing brush for routine cleaning of hard floors on a compatible Powr-Flite 20-inch rotary floor machine.

How do I know if my Powr-Flite MG218M scrub brush needs replacing?

Replace the Powr-Flite MG218M scrub brush when the bristles are visibly shorter, splayed, or bent so the brush no longer holds even contact with the floor, when scrubbing takes more passes than it used to, or when the brush leaves an uneven result. Worn bristles lose the medium-grit bite that makes the brush effective.

What machines is the Powr-Flite MG218M scrub brush (part# MG218M) compatible with?

The Powr-Flite MG218M scrub brush fits the Powr-Flite 20-inch, 1.5 HP floor machines: the C201HD Classic Metal, C202 Classic Metal Dual-Speed, NM201HD Millennium, and NM202 Millennium Dual-Speed. MG218M is the current medium-grit brush and replaces the discontinued PFLG18, PFMG18, PFHG18, PST18, PFMG19, PFHG19, PST19, and PST20 brushes.
