Lindhaus LW52 Disc Brush 0.20 Soft Black (2 Pack)

Marble, coated hard floors, and other finishes that scratch easily call for the softest brush Lindhaus makes for the LW52 Flexy, a 0.20 mm black-coded disc sold here as a two-pack, SKU 184650081. At about 0.5 kg for the pair, the discs are sized to the LW52's wider cleaning head rather than the smaller LW44.

The thin 0.20 mm bristle flexes easily under the machine's drive plate, so it agitates without the bite of the medium or hard grades in the range. That gentleness is the point, it lets the LW52 clean sensitive sealed surfaces without dulling the finish the way a stiffer brush could.

Because the discs are sold as a pair, changing both at once keeps agitation even rather than running a new disc alongside a worn one. Flattened or splayed bristles signal it is time to replace the set, keeping the softer touch available for the floors that need it.

Grade confusion is the practical risk with a three-brush range. Once the discs are off the machine and sitting on a shelf, the softest and the hardest are easy to mix up at a glance, and a polished floor scrubbed with the wrong disc is not something a second pass will undo. Label the set, or store it well away from the medium and hard discs.
