CHOOSING AND USING THE BRUSHES 

 
POLYPROPYLENE BRUSH (PPL) 
Used on all types of floors. Good resistance to wear and tear, and hot water (no greater than 60°C). The Polypropylene brush is non-hygroscopic and 
therefore retains its characteristics even when working in wet conditions. 
ABRASIVE BRUSH 
The bristles of this type of brush are charged with highly aggressive abrasives. It is used to clean very dirty floors. To avoid floor damage, work only with the 
pressure strictly necessary. 
THICKNESS OF THE BRISTLES 
Thicker bristles are more rigid and are therefore used on smooth floors or floors with small joints. 
On uneven floors or those with deep joints, it is advisable to use softer bristles which can enter the gaps more easily. 
Remember that when the bristles are worn and therefore too short, they will become rigid and are no longer able to penetrate and clean deep down. In this 
case, like with over-large bristles, the brush tends to jump. 
PAD HOLDER 
The pad holder is recommended for cleaning shiny surfaces. 
There are two types of pad holder: 
1.

 

the traditional pad holder is fitted with a series of anchor points that allow the abrasive floor pad to be held and dragged while working 

2.

 

the CENTRE LOCK type pad holder not only has anchor points, but also a snap-type central locking system in plastic that allows the abrasive floor pad 
to be perfectly centred and held without any risk of it becoming detached. This type of dragging device is recommended above all for machines with 
more than one brush, where the centring of the abrasive discs is difficult
