1.2 GENERAL WARNINGS
POWER CORD WITH PLUG
• Check the power cord regularly to see if there is any sign of damage:
• If the power cord is damaged, replace it before using the machine.
• Use a cable of the same type used by the Manufacturer, certified according to “ENEC”
European standards
• Cable replacement must be performed by qualified personnel.
AVOID ANY CONTACT OF THE POWER CORD WITH BRUSHES
• Should the power cord get caught under the machine brushes, do not attempt to get it out
with the machine working. Stop operation immediately, remove the plug from the power
socket, check the cord. If damaged, do not try to repair it simply putting a tape around it,
but replace it.
OTHER WARNINGS
• Ensure the machine does not sit on the brushes when in its rest position, but that it is
supported and raised by the tripod (Fig “1.15” - page 25).
If this not the case, the machine weight could warp the brushes.
• Do not pour water or liquids directly onto the machine.
• Unplug the power cord plug from the power socket or battery before any maintenance
intervention.
• Store the machine in a closed and dry place after use.
• The machine is designed and constructed exclusively to clean floors. Any other use is

1.3 DISTINCTIVE FEATURES AND COMPETITIVE ADVANTAGES OF
DUPLEX 280i
The DUPLEX brand name is synonymous with double efficiency and distinguishes a machine
that actually has a dual function thereby providing numerous advantages for the best possible
floor cleaning and hygiene.
• SMART BRUSHES
The unique smart brush system “patented” by DUPLEX allows the machine to reach more
easily into corners and along skirting boards of every surface.
• EASY-TO-DISASSEMBLE BRUSHES
The brushes are inserted with a patented "trigger fitting" which enables them to be removed
and replaced in just three seconds.
• OPTIONAL BRUSHES
They are provided for any type of floor and cleaning operation
• BI-DIRECTIONAL CLEANING SYSTEM
This system allows the work position to be reversed thanks to the bi-directional handle.
(see figure “1.1”, “1.10” and “1.13” ).
• DOUBLE WASHING SYSTEM
Two powerful brushes rotate in opposition at 3.75 mt/s, attacking dirt and trapping it with
their synergistic action and delivering it towards the two conveyor belts.
• DUAL DIRT COLLECTION SYSTEM
The patented conveyor belts which rotate quickly channel the dirt deposited on their surfaces
directly into the recovery tank.
• RECOVERY TANK
Situated conveniently in the middle of the machine and easy to remove. It is equipped with
two “scrapers” made of a special technopolymer, they are easy to replace and are needed
for the final collection of dirt.
DUPLEX 280i
8
• DOUBLE USE SYSTEM
Simultaneous washing and dirt recovery.
Soaking followed by dirt recovery.
• WATER AND DETERGENT TANK
Easy to remove and to refill under a water tap and to empty at the end of cleaning. This
system makes cleaning it easier.
• ADVANCED CONSTRUCTIVE TECHNOLOGIES
Forty years of activity and more than two hundred thousand DUPLEX machines manufactured
and sold worldwide, have allowed our Company to gain considerable experience, improving
our valuable and prestigious know-how.
Today, our know-how allows us to develop highly innovative technologies which find their
application in the design of the most cutting-edge floor cleaners, as happened recently in
the case of the new DUPLEX 280i.
Besides being able to clean perfectly any type of flooring by means of a new operational
concept, the DUPLEX 280i is equipped with a robust structure which can withstand heavy
use even exceeding allowed use limits, or in any case, it can tackle any involuntary distraction
of the user.
It cleans easily every floor including rugs, fabric flooring, carpets, etc. It can easily pick up
fine or coarse dirt, any type of solid dirt (cigarette butts, paper sheets, sand, etc.). It cleans
and removes dirt from the most deep recesses of any type of floor, embossed, studded
rubber flooring, etc.
In designing the DUPLEX 280i, we aimed to create a perfect machine. Each of its components
has been designed to ensure maximum safety and durability, without requiring any maintenance.
To this end a special pressure-diecast light alloy casing has been manufactured to enclose
all electrical parts and most sensitive mechanical gear drive parts in order for them to be
fully protected.
• ELECTRIC MOTOR
This motor has been made perfectly seal-tight by means of rubber seals on each closure
and its external part is treated by an Anodic and Galvanic procedure to make it rustproof.
• EASY-TO-USE AND PERFECT BALANCE
The motor's central position and the tank above give the machine a perfect balance.
The weight distributed equally on the brushes allows an efficient cleaning. It is particularly
easy to handle for whoever uses this machine.
DUPLEX 280i

• TRANSPORTABILITY
The DUPLEX 280i AC weighs 13 kg.
The DUPLEX 280i DC plus Lithium Ion battery weighs only 12 kg.
The Duplex 280i can be carried easily given its reduced weight (13 kg max.), allowing anyone
to lift it. Moreover, it moves silently on its two small rubber wheels.
• QUIET OPERATION
Noise level and vibration dBA < 72.8

1.4 TIPS FOR CLEANING FLOORS
CLEANING CARPETS OR RUGS
Fit the yellow brushes (option).
We advise you to cross the washed tracks so that all fibres appear well cleaned taking care not
to wet them too much.
Carry out a few tests before starting to wash.
Use a non-foaming detergent appropriate to clean carpets or rugs.
LITHIUM ION BATTERY DUPLEX 280i DC
The lithium ion battery power decreases slightly when brushes face a
greater friction cleaning and washing fabric flooring.
CLEANING WOOD PARQUET
Fit the yellow brushes (option) or the supplied grey brushes if the parquet is very dirty.
Do not wet the floor too much, and in particular not painted flooring, which absorbs more moisture.
Be careful when cleaning this type of floor. Carry out a few tests before washing the entire
surface.
Use a non-foaming detergent appropriate for parquet flooring.
CLEANING ALL TYPES OF FLOORING
Install the supplied grey brushes.
Use an non-foaming and non-acid all-purpose cleaner (PH max. 9).
CLEANING HEAVILY DIRTY, HARD OR DINGY FLOORS
Fit the black brushes (option).
Use a concentrated non-foaming and non-acid all-purpose cleaner (PH max. 9).
DUPLEX 280i
11
CLEANING FLOORING WITH WAX CLEANERS
Some floors are well suited to be cleaned and treated at the same time with WAX CLEANERS,
such as:
• Florentine terracotta tiles
• Smooth tiles
• Clinker
• Marble
• Granite
• Industrial flooring
• Studded rubber flooring
• Wood flooring
• Old wax-treated flooring and many other.
WAX CLEANER “Shiny effect”
Fit the supplied grey brushes, use any wax cleaner available in shops, mix it with water
(see the instructions on the bottle for the dose). Follow the instructions on paragraph
“1.10 HOW TO WASH FLOORS” (Phase 1 and 2).
When cleaning is complete and the floor is thoroughly dry, wipe again after fitting the
brown polishing brushes.
Doing this you will obtain great results and have the entire surface cleaned to perfection with a
“shiny effect”. Moreover, dirt will be immediately recovered in a simple, quick and convenient way.
POLISHING WAXED FLOORS
Fit the brown brushes (option).
Turn the recovery tank knob to “1” (In this case only the brushes work and the recovery system
is deactivated).
DUPLEX 280i
12
SOAKING/WASHING HEAVILY DIRTY FLOORING
When you need to scrub flooring that has been dirty for a long time and has every sort of spots
and dirt, you are advised to proceed as follows:
1.
Fit the supplied grey brushes for medium dirt or the black brushes (option) for heavy dirt;
2.
Raise the recovery tank turning the knob and set it to 1 (Fig. 1.2). In this setting the recovery
system will not work and the liquid poured onto the floor will require a more emulsified solution,
and therefore, it will allow the detergent to
be more effective (“soaking”).
3.
Press the lever to dispense a large amount
of detergent consisting of product/water,
preferably warm at a temperature of
35/40°C.
4.
Move the machine forward on the entire
wet surface, in all directions or following
precise tracks;
5.
Stop the machine and turn the knob to “0”
to lower the tank and re-activate the dirty
water recovery system.

SUPPORT TRIPOD AND FOR BRUSH PROTECTION
When you have finished using the machine,
place it on the support tripod to prevent the
brushes from getting deformed if they rest
on the floor.
The tripod is at the end of the machine and
can be put in position raising the machine
slightly on one side and making it turn towards
the floor (fIGURE 1.11).
Figure 1.11
MOTOR PROTECTOR
The “Motor Protector” (MP) (Figure 1.12), is a safety device which stops the machine in case
conditions occur that overload the motor (e.g. foreign
bodies caught in the brushes which can prevent their
rotation, locking of the brushes for failed start-up due
to great friction with the floor, mechanical fault, electric
motor fault, poor supply of power, overheating, etc.).
DUPLEX 280i AC: Disconnect the machine from the
power socket before removing any foreign bodies
caught in the brushes.

BRUSH MAINTENANCE:
Brushes require little routine maintenance. The high rotation speed during cleaning manages
to centrifugate dirt and keep them clean and efficient at all times.
However, check their state, and if necessary, proceed as follows:
1.
Remove the brushes from the machine;
2.
Immerse them in a container of cold or lukewarm water and let them soak for a few hours;
3.
Stir and rinse well;
4.
Re-fit the brushes in reversed position in relation to the one they had before. This operation
is required to correct the bending of the bristles.
5.
BROWN POLISHING BRUSHES:
Wash the brushes after each use to keep them in good working order. Immerse them in
lukewarm water and diluted degreasing detergent. Stir and rinse. Use them only when
thoroughly dry.
BRUSH DEFORMATION
Wear and storing the machine without lowering the tripod ( 1 Figure 1.15) can cause the brushes
to warp resulting in bouncing and/or vibrations during work stages.
Replace the brushes to prevent damaging the machine.

1.15 DISPOSAL AND WASTE SEPARATION
Pursuant to art. 13 of Legislative Decree of 25
th
July 2005, no. 151 “Fulfilment of the Directives
2002/95/EC, 2002/96/EC and 2003/108/EC on the restriction of the use of certain hazardous
substances in electrical and electronic equipment and disposal of their waste”.
The crossed-out bin symbol on the equipment indicates
that at the end of its lifespan, the product, must be collected
separately from other waste.
The user must deliver the DUPLEX 280i, at the end of its
lifespan, to an appropriate collection point for the recycling
of electric and electronic equipment or deliver it back to
the retailer when purchasing a new equivalent machine on
a one-to-one basis.
Correct disposal of the DUPLEX 280i for its recycling and
treatment will help prevent potential negative consequences
for the environment and human health, and will help
recycling the materials of which the machine consists.
Disposal of lithium ion batteries
The DUPLEX 280i DC is equipped with a lithium ion battery inserted in an appropriate fireproof
plastic enclosure, hermetically closed and easy to remove from the machine by simply unscrewing
a knob manually.
The battery, at the end of its lifespan, must be disposed of separately from other waste.
WARNING
Do not burn lithium ion batteries as they could explode or blow up violently.
Carefully collect the batteries for disposal. Avoid them being short-circuited
or their enclosure being compacted or destroyed.
Check and follow all local, regional and national laws on the disposal of
these materials. The user is legally responsible for hazards generated
during the disposal of batteries and preservation of material resources
which enable the recovery of valuable materials.
Abusive disposal of the DUPLEX 280i by the user entails the application
of penalties according to the regulations in force. Professional users
who decide to dispose of the DUPLEX 280i at the end of its lifespan and
purchase a new equivalent machine with the same features can agree upon
the collection of the old DUPLEX 280i and delivery of the new machine.

1.16 LITHIUM ION BATTERY (DUPLEX 280i DC)
FOREWARD
New lithium ion batteries have a higher energy density if compared to conventional batteries.
They are more compact in size and weigh less compared to old lead batteries in their various
variations, lead acid, gel lead, calcium lead and hermetic batteries.
If, on one hand, lead batteries cost less, on the other they are very heavy and require specific
maintenance. They produce hydrogen when recharging (pollutant gas) and contain lead (a
cancer causing and tetragonus agent). They require to be disposed of according to severe
and precise methods. Our choice to use lithium ion batteries to supply the DUPLEX 280i DC
is a major step forward, bearing in mind the future as we are among the first to use a type of
long-range technology, able to activate the first floor cleaner worldwide. The machine is fitted with
two powerful and smart cylindrical brushes along with a patented high performance collection
system of solid and liquid dirt.
As for all other lithium ion batteries used in other devices: computers, mobile phones, vehicles,
towing vehicles, etc. their durability over time is determined by the number of charging cycles,
which sometimes exceeds 2,000 cycles.
Re-charging can take place at any time without requiring them to be fully discharged by means
of their appropriate battery charger. Should they be inadvertently charged using a conventional
battery charger for lead batteries, they will be irreparably damaged.
PRECAUTIONS
The lithium ion battery autonomy can be compromised if it is deposited, used or recharged in
places at temperatures exceeding 40°C. On the other hand, using and storing the battery in a
cold environment will reduce its duration, but in this case it is a fleeting issue as battery capacity
is restored by recharging it.
Exposing the battery to sun rays can damage it irreparably.
PARKING THE MACHINE WITH BATTERY
If the machine is not used for long periods of time and is left parked, the battery might selfdischarge. Therefore, it needs to be recharged every 40 days.
REPLACING OR DISPOSING OF THE BATTERY
At the end of its lifespan, do not burn lithium ion batteries as they could explode or blow
up violently.
Do not dispose of with other waste. Dispose of batteries delivering them to the authorised
collection points.

F) Do not try to open the battery fireproof plastic enclosure.
G) Do not break or pierce the battery pack: Extremely dangerous!
H) Do not burn: violent explosion or blow up hazard.
I) Do not weld the cables at the ends of the batteries.
J) Do not short circuit positive and negative terminals.
K) Stock and store in a cool and dry place.
L) For their correct disposal, see and follow all local, regional and national laws on the disposal
of these materials. The user is legally responsible for dangers generated during battery
disposal.
BRIEF HISTORY OF LITHIUM ION BATTERIES
Lithium ion batteries take advantage of the high electro-chemical potential of Lithium (compared
to its low overpotential) and their low weight. Other advantages lie in high energy (mass and
volume), long cycle duration and minimum self-discharge. Moreover, using lithium accumulators
you do not run the risk of contaminating the environment as it happens with lead or cadmium
accumulators. Recharge times are short and have no memory effect. Even if they require particular
chargers, their cost prevents them from being widely distributed even if their use is expanding.
Lithium can be found abundantly in nature, even if it never occurs freely because of its high
reactivity. It can be found in small amounts in all igneous rocks and salts from mineral springs.
Starting from the Second World War, the production of lithium has grown considerably by separating
the metal from the other elements of igneous rocks or extracting it from mineral water springs.
Lithium comprises the following minerals: Lepidolite, Spodumene, Petalite and Amblygonite.
However, the discovery of lithium batteries is not recent. Gilbert N. Lewis manufactured the first
lithium ion batteries in 1912, even if they were produced and first launched on the market by
Japanese Company SONY in 1991.
