NaceCare Duplex Red Max Abrasion Ultrabrush for the Duplex 420 Scrubber

The Duplex 420 runs 2 brushes. Choose 1 Brush to replace a damaged one, or Set of 2 to change both sides at once.

The Red UltraBrush Max is the heavy hitter in the lineup. Maximum-abrasion bristles built for the jobs where Blue and Yellow tap out. When your floors are fighting back, this is the brush that fights harder.

Best for: Bare concrete cleaning, deep grout restoration, industrial flooring with caked-on grime, warehouse floors, parking garages, mechanic shops, and any surface where the soil is older than your last cleaning contract. Also the right choice for one-time deep restoration projects before you go back to lighter daily brushes.

Daily maintenance on softer surfaces? Use the Blue UltraBrush Soft. Grouted tile and medium soil? Try the Yellow UltraBrush Medium. A heads-up on the Red Max: it's aggressive by design, so don't run it on finished hardwood, marble, or anything you'd hate to see scratched. Replacing both brushes at once keeps the two sides of the machine wearing evenly.
