It is used on every type of floors and has good resistance to wear. The Polypropylene brush is non-hygroscopic and therefore retains its characteristics even
when working in wet conditions.
THICKNESS OF THE BRISTLES
The thicker bristles are more rigid and should therefore be used on surfaces with solid or heavy dirt (e.g. gravel; drinking cans; etc.).
Softer bristles are recommended for surfaces with light dirt or dust.
Remember that when the bristles are worn, and therefore too short, they become rigid and cannot pick up the dirt efficiently.
The central brush has bristles of 1.1mm and of 0.7mm to comply with both characteristics.
