Brush Recommendations:
Polypropylene Brush（PPL）
This general purpose scrub brush is recommended for all
floor types and offers good resistance to wear and to hot
water (not over 60°C / 140°F). PPL is not hygroscopic (it
does not absorb moisture), and is ideal for working on wet
floors.
Nylon Brush
This brush is used on all floor types and offers excellent
resistance to wear and to hot water (not over 60°C /
140°F). Nylon is hygroscopic (it absorbs moisture) and
tends, over a period of time, to lose its character when
working on wet floors.
Pad Driver
Scrubbing pads are recommended for cleaning polished
surfaces, there are two types of pad holders:
1. Traditional pad holders with set of anchor stubs that
hold and turn the scrub pad during operation.
2. Center lock pad holders that have anchor stubs and a
plastic snap-in center lock system. This allows perfect
centering of the scrub pad and ensures it is kept
anchored without slipping during the operation of the
machine.
Consult your local dealer or service center for more details
about scrub brush and scrub pad/driver types & uses.
