BRUSH SELECTION AND USE
POLYPROPYLENE BRUSH (PPL)
This is used on all types of floors and offers good resistance to wear and to hot water (not more than 50°C). PPL is not hygroscopic and
consequently preserves its characteristics even when wet.
BRISTLE THICKNESS
The thicker bristles are more rigid and consequently are used on smooth floors or with thin gaps.
It is better to use softer bristle brushes on uneven floors or floors with deep gaps or humps since these penetrate more easily.
Remember that when brush bristles are worn and then too short they become rigid and are unable to penetrate and clean in depth. Bristles which
become too big, among other things, cause the brush to tend to skip.
DRIVE DISK
Drive disk, recommended for cleaning polished surfaces, is equipped with a set of anchor stubs that retain and drive the abrasive disk during
operation.
