| In Practice | Wiping Systems
Three types of wiping systems
Generally speaking, three groups of wet wiping systems are available:
33The classical wide wiping system with a flat mop and basket or flat
33The double mop system with basket or flat wringer.
33The floor mops or spaghetti mops with basket wringer.
How economical a system is depends on various factors. These

far behind microfiber covers – they can only clean eight to ten
square meters at one go.
A double mop can handle up to 30 square meters
The double mop method, which also has a working width of
40 centimeters and a high proportion of viscose, represents for
wet mopping 2.0 and can clean up to 30 square meters. This is due
to the use of both sides of the mop and the time savings (about 30
percent) through less frequent mop changes.
Area cleaned depends on preparation
Preparation of the mop cover is another important factor for
the hourly output per square meter of all systems except the
mop. The classic dunk and squeeze method – or use
of the “
pre-prepared” procedure? With microfiberdouble mop
using the pre-prepared procedure, floor areas of up to
450 square meters can be cleaned per hour using the one-step
wet-mopping procedure. With conventional wide mop covers and
prepared procedure, only 350 to 400 square meters per
hour can be cleaned. These values refer to one-step wet wiping
with microfiber mops.
Area performance sinks with cotton mops
Cotton has nearly no mechanical cleaning effect and always
requires two-step wet wiping. The cleaning capability of cotton
is based on the fact that in the first work step, the cleaning agent
dissolves stains. During the second step, after washing out or
exchanging the mop, the cleaning solution is picked up with the
chemically dissolved protection layer.
Thus, for the hourly output per square meter, it is not primarily
the wet mop system used that is crucial, but whether the mop is
made of cotton or microfiber. Another big disadvantage of cotton
covers is that when wet mopping, cotton releases only about one
third of the cleaning solution it has taken up. Microfibers release
70 percent and more, depending on the proportion of viscose and
the mop construction.
Two-step mopping takes longer
If two steps are used for the cleaning process, the hourly output
per square meter sinks by about 50 percent, no matter which
system is used. But the double mop method still retains the time
advantage gained from reduced mop changes of circa 30 percent.
An additional advantage of this method is that when the two-stage
wet mopping process is used, chairs can be immediately set up
again because the dry side of the double mop can be immediately
used to wipe up. This eliminates having to return to the cleaning
cart to get and mount a new dry mop to wipe up the remaining
moisture. Chairs must not be moved twice.
The purchasing and preparation costs for floor cleaning systems
are somewhat different. The most expensive system to purchase
is the double mop system (mop holders and cleaning textiles). In
practice, the costs are about twice as much as those for a classical
wide mop system with a flat mop. The most economical system by
far is the floor, or spaghetti, mop - in terms of acquisition costs.
Comparison of lifecycle costs
In regard to lifecycle costs, i.e. the costs per square meter cleaned,
including preparation and natural wear and tear, the double mop
system is the most economical.
Per square meter of area cleaned, the costs of a flat microfiber mop
are 0.0060 euros per square meter or 0.097 euros for 16 square
meters. With flat cotton mops, the costs are around 0.0103 euros
per square meter or 0.103 euros for ten square meters. With a
microfiber mop, the price is 0.0054 euros per square meter or
0.150 euros for 28 square meters.
This calculation includes the operating costs for washing
machines, dryers, detergent,
operating personnel, energy costs,
of the machines and mop covers as well as
Microfiber mops can be washed 600 times
In terms of durability, microfiber mops are calculated with the
capacity for 600 washes or uses; cotton mops can only be washed
or used 350 times. The operational costs of mops also include
the time necessary for mop changes as well as the working time
of the cleaners. With the conventional wide mop system with
this would be theoretically 22 changes, for systems
with cotton 35 changes and with double mop systems 13 changes
for 350 square meters cleaned.
In conclusion, it can be said about wet mops and their systems
that microfibers with viscose perform around 15 to 20 percent
better than microfiber without viscose; microfiber achieves around
50 percent better performance than cotton fibers. The double
mop method is about 30 percent more powerful than the classic
method with a flat mop, and the double mop system
reduces changes by circa 30 percent. N
