5. TECHNICAL INFORMATION

5.1 GENERAL DESCRIPTION

5.1.1 MACHINE

We can summarise the machine' s main features as
follows:
- The form of the squeegee, the air flows and the
specially designed rubber blades produce excellent
drying results even on tiled floors. Thanks to the particular
balanced shape of the machine frame and the squeegee
support, no water residues are left behind in a curve,
and even when a smaller squeegee is used.
- Excellent distribution of weights and geometries: the
centre of gravity is very low , also thanks to the very
heavy brush plate and because the batteries are located
at the level of the wheels.
- A heavy weight on the brushes makes them work
efficiently on the floor. The pressure is generated by
the weight of the plate, without springs or additional
devices that lead to dif ficulties and inaccuracy. The
entire mass is generated by the hanging weight of a
15 mm steel ship's plate.
- A large volume of water in the t anks reduces dead
time since fewer trips are needed to collect water and
dump dirt. There is no delicate flexible diaphragm that,
at a technical level, is difficult to clean.
- A few dozen litres of water in the recovery t ank are
used to decant any foam (dangerous for the suction
motor). The cone under the top cover of the tank that
separates the foam area from the air suction area acts
as another decanting system. The inner area of the
cone is "sealed" at the bottom against the rising water.
The air, from which the foam - that remains out side -
has been removed, is vacuumed from the pores at the
top. The traction system is designed for the machine
weights, making the machine responsive and easy to
handle.
- Robust construction. The frame and the squeegee,
built with thick sheet metal - thickness 6 mm, 8 mm, 10
mm up to 20 mm – are laser cut and welded. The brush
plate is made from 15 mm ship' s sheet metal, with a
surface treatment that protects the plate and the paint
for thousands of hours in a saline fog. All screws are
made with stainless steel; the tanks (body) are made
with 7-8 mm thick shockproof polyethylene. Everything
is simple and very strong, without any other complicated
designs.
- The battery comp artment can house very large
batteries, which guarantees extended running time.
- The suction motor is housed inside the machine, thus
reducing operating noise to a minimum.
- The recovery tank is very easy to clean due to the
lack of the characteristic dif ficult access point s of
recovery tanks located in a lower position.

5.1.2 BATTERY

To make handling easier (considering the weight s
involved) and to avoid situations that may be dangerous
for the batteries and for the operator, we offer only box-
type battery units for this machine. This power supply
unit configuration not only is robust, but is necessary
in order to offer high performances (Ah capacity).
Regardless of the type of construction, battery
performances are indicated with the term cap acity,
which always refers to a discharge period. Another
important value is the number of possible discharges.
The capacity is expressed in amps per hour (Ah), while
the discharge period is generally indicated as 20 hours
(C20 or 20h, or not expressly indicated) or 5 hours (C5
or 5h). The discharge/charge cycles indicate the number
of times that the battery can hold a charge under the
best conditions, i.e. they indicate the useful battery
service life complying with all the necessary measures.
Therefore, the capacity of a battery varies depending
on how fast it uses energy (current). That's why there's
such a variation in the cap acity values expressed as
C5 or C20. These factors must be taken into account
when comparing products available on the market with
our own.
This machine can be equipped with two types of batteries
that differ in terms of their construction and features.
- Pb-Acid battery with tubular armoured modules (box
type): the electrolyte level in each element must be
periodically checked!
If one element is no longer covered by the acid
solution it will oxidise in 24 hours, thus permanently
affecting that element's performance.
Refer to the battery manual to avoid physical damage
and economic loss.
- Gel module battery (box type): this type of battery is
maintenance free and does not require special
environments for recharging (since it does not emit any
harmful gases); therefore, it is highly recommended.
It should not be taken for granted that batteries
and battery chargers with the same technical
features as those we offer will produce the same
results. Only perfect compatibility between these
elements (Pb-Acid batteries, gel batteries and battery
chargers) will safeguard the performances, the
service life, the safety and the economic value
invested.

5.1.3 BATTERY CHARGER

This type of high-frequency battery charger efficiently
charges batteries, extending their operating and service
life. In addition, because they can be configured with
optional smart cards (magnetic badges), it is a very
versatile solution that reduces the number of chargers
required in the warehouse. The same battery charger
can be used for both Pb-Acid batteries and for gel
batteries.
The information indicated on the digital display can be
used to always keep the charging process, the battery
and the battery charger under control (read the specific
manual for more details).
It should not be taken for granted that batteries
and battery chargers with the same technical
features as those we offer will produce the same
