Melamine pads (Dr. Rauwald, Tana, l. to r.). Microfiber pads (Vermop, Vileda), cotton pads (Taski, Solution-Glöckner,

and mainly plastic (e.g. polyamide, polypropylene,
Natural bristles are irregular in length and cross-section and
do not build up an electrostatic charge. Due to swelling, their
change when working in wet areas and they dry more
slowly than plastic bristles. Plastic bristles are relatively sensitive
to hot water, but generally more abrasion-resistant. Brushes made
of polyamide (nylon) are only partially acid-resistant and thus not
suitable for all applications (e.g. swimming pool cleaning, basic
Compared to conventional cleaning pads, brushes are advantageous
when cleaning seams and structured flooring because they can
get into all the cracks. For strongly structured flooring surfaces,
so-called high-low brushes are offered.
The various kinds of brushes include

Pads/Floor cleaning discs
Floor cleaning discs, also called pads, are disc-shaped non-woven
materials made of polyester and/or polyamide (nylon). They are
offered as accessories for scrubber and scrubber vacuums with
one-disc, multi-disc, roller, eccentric or oscillating scrubbing units.
Pads are categorized as
33high-speed polishing pads, or
Depending on the degree of abrasion, the pads are designated
according to different (not standardized, but typically used!)
above, l. to r.), microfiber roller (Kärcher, below).
Note that the abrasive materials or abrasive grits of a red
pad are not softer, but only finer than those of a black pad.
Various diamond pads are available. These special pads contain
fine diamond particles of different grains (usually only on one
side of the pad) attached to the material with a plastic glue, or in
Employed with one-disc machines or suitable scrubber dryer
machines, diamond pads can be used to finely grind and polish
natural and artificial stone flooring (flat-sanded or polished) as
well as synthetic-resin-modified industrial floors. Even worn polyurethane
flooring on elastic surfaces can be ground or sanded
with diamond pads. In addition, diamond pads are outstanding
for renovating crumbling elastomeric flooring (rubber). But the
color-coding of diamond pads does not correspond to the abovenamed
color-coding of conventional floor cleaning discs! The diamonds
must first be scrubbed free in order for the pads to achieve
their full cleaning performance.
Melamine pads are floor cleaning discs made of melamine resin
foam, which is also designated as a dirt eraser. They are good
problem solvers for stubborn stains. The excellent cleaning effect
of these white/gray-white, finely structured foam pads – which
can only be used when wet – is due to the very abrasive action of
the hard material.
When used, very fine melamine resin particles are rubbed off
the foam material and act as an extremely fine abrasive, i.e.
the melamine resin foam gradually dissolves during cleaning.
Melamine pads are especially good for removing persistent dirt
