Lindhaus LW52 Disc Brush 0.40 Hard Yellow (2 Pack)

For soil the medium brush cannot break down, Lindhaus makes a 0.40 mm yellow disc brush for the LW52 Flexy, the hardest bristle in the lineup, sold here as a two-pack under SKU 184660081. Sized to the LW52's wider cleaning head, the pair weighs roughly 0.5 kg.

The thicker bristle carries more scrubbing force per pass than the red or black discs, which suits textured, rough, or heavily soiled hard floors, dried-on residue and ground-in traffic grime respond to this brush where a softer one only spreads the soil around. That same stiffness makes it a poor match for polished or coated surfaces, where it is better to switch back to the medium or soft disc once the heavy cleaning is done.

Both discs ship as a set so the LW52 scrubs evenly across its full cleaning width instead of running one fresh brush against a worn one. Replace the pair once the bristles flatten or splay from repeated heavy use.

Treat the yellow set as a job-specific tool rather than a default. Left mounted for everyday passes it wears down faster than the work justifies, and on a coated or polished surface it can leave marks that then need a softer disc and another pass to bring back.
