The T20i is the Brand-New solution for fast and efficient travelator and escalator cleaning from Rosemor
International. The T20i has been designed from the ground up to replace the previous T10i model. T20i is a
compact and easy-to-use, automatic escalator and travelator cleaning machine, suitable for most escalators
and travelators in existence today. Unlike the Rotomatic, the T20i will only clean the flat, horizontal portion of
an escalator and travelator tread.
The T20i is used while the escalator or travelator is moving (towards you), which makes it a very quick method
of performing a cleaning operation.
Compared with its predecessor the T10i, the T20i has had some major improvements implemented:
- Redesigned the detergent dispensing system to provide better detergent coverage and reduce striping.
- Automatic cleaning head lifting system, removes the need for the operator to lift machine into place.
- Simplified the guide wheel adjustment system, for easier ‘one-touch’ operation.
- Removed the transit wheel system from the front of the T20, to make operation simpler.
- Made some adjustments to the vacuum system, to reduce the chances of blockages.
- Huge 20L detergent/wastewater capacity.
- Much easier to manoeuvre machine, compared to the previous T10i.

Rosemor International Ltd reserves the right to adjust the machine and any documentation. This
operation and maintenance instruction manual is intended for service personnel only.
Preliminary remarks
Safety and reliability are essential to guarantee a long and trouble-free service life of the T20i. In
order to fulfil these requirements, the operator must obtain sufficient skills in both handling and
operating the machine and of its maintenance and care. It is therefore vital that the operator
receives instruction and training from either Rosemor International Ltd or one of its specialists
before the cleaning machine is used for the first time.
This operation and maintenance manual only represent additional assistance for the operator in
correct and safe use of the cleaning machine. Reading this manual does not qualify any person for
safe use of the T20i.
Rosemor International Ltd or one of its customer service centres should be informed immediately if
any technical fault in this cleaning machine is suspected or has occurred.

3. Operation
31/3/2022 Written and illustrated by Ben Sprules
Rosemor International Ltd 2022 © 11
3.1 Before Starting
All local safety regulations and instructions
must be observed before each start-up. The
escalator/travelator must be inspected jointly
with the party responsible for the machinery,
who should also be informed of any
discoloration or paint stains etc. caused by
repair and renewal work.
3.2 Check operation of Travelator/Escalator
During the cleaning operation, the
travelator/escalator will need to move towards
the machine. Now is a good time to check that
the travelator/escalator moves as required.
3.2.1 Preparing the T20i:
3.2.2 Filling Detergent Tank (See Pg.8)
- Detach quick-release coupling
- Place hand behind black lid of tank and pull
forward towards you (Fig 3). Allow tank to
rest on machine & handle so you may obtain
a steady grip on the front and rear of the
tank.
- Unscrew lid to fill. You may add up to 20 litres
of premixed RC-91 detergent. The dilution
ration for RC-91 is 10:1 (water:detergent).
3.3.1 – Replacing Tank
•When the detergent tank is refilled, rest the
end of the tank on the machine and slide the
tank forwards until the tank locates and locks
into position on the lower tank stops. Be
careful not to push the tank too far.
•Reattach quick-release coupling by pushing
male end into female connector on tank.
•Confirm detergent flows freely by briefly
pressing ‘Detergent’ button on the button
panel until detergent can be seen coming
from underneath the T20i Cleaning Head. Be
sure to mop/soak up any detergent left on the
floor to prevent the chance of someone
slipping.
The travelator/escalator must
move towards the T20 during
cleaning. If the
travelator/escalator moves
away, The machine will not
clean or dry the treads
properly.
Always keep hands and
body parts away from the
moving machinery. Always
remove hand/wrist jewelry
and wear short sleeved shirt
when inspecting brushes.
Note: Filling the detergent tank
with just 11-16 litres of
detergent is recommended as
this makes it much easier to lift
and maneuver the tanks when
full and reduces the chance of
a lifting associated injury,
accident or detergent spillage.
Every time the detergent tank
(Pg.8) is refilled, it is of the
upmost importance that the
wastewater tank (Pg.8) is also
emptied at the same interval,
regardless of how much
wastewater is present in the
tank. This prevents accidental
overfilling of the wastewater
tank and subsequent damage
to the machine’s vacuum motor
system.

3. Operation
31/3/2022 Written and illustrated by Ben Sprules
Rosemor International Ltd 2022 © 12
3.4 Preparations on Site
The cleaning date should be co-ordinated with
the maintenance personnel (possibly process
electrician) in charge of the escalator.
The safety manager should also be informed if
necessary.
The operator must plug in the mains cable for
the machine, or a suitable socket must be
shown to him.
The operator must furthermore obtain
professional instruction on the manual control
of the escalator or else ensure that some
person familiar with the workings of the
escalator is always available near by.
3.5 Safety measures on site
All unauthorised persons and the general public
must be physically prevented from approaching
and entering the entrances at both ends of the
escalator/travelator by means of proper safety
measures (e.g. barrier etc).
The machine and any accessories are to be
placed in the cordoned-off level area at the
bottom of the escalator to prevent any
unauthorised contact.
3.6 Preliminary Inspection and Work
Inspect the escalator/travelator thoroughly and
report or take note of any pre-existing damage,
mark or any other form of permanent stain etc.
Note: T20i cannot repair any scratching or
erosion caused by historic wear, corrosion, poor
maintenance or accidental damage. It may
actually appear worse after cleaning as any dirt
that might have been disguising it will have been
cleaned off and removed making any pre-
existing damage more prominent.
Remove any obvious large foreign objects by
hand, such as drinks bottles/cans, cigarette
boxes and other general litter.
Remove any large particulate dirt from the
grooves in the steps with a hand rake before
allowing the T20i to clean it, as this could
impede the way in which T20i cleans and
collects the wastewater.
Have the escalator/travelator
operated by the relevant
specialists and secured against
being switched on by accident
during cleaning!
3.8 Positioning the machine on an escalator or
travelator.
Ensure the escalator or travelator is switched
off and is stationary.
Roll the T20i partially onto the flat steps at the
bottom until the front cleaning head is
completely above the treads.
Apply the brakes on the rear transport wheels
to lock the T20i in place (Pg. 8)
With the brakes applied, check that the machine
cannot move forwards or backwards.
Only ever load the T20i onto the
bottom of the escalator/travelator.
Never, under any circumstance,
attempt to clean an escalator (or
ramped travelator) from the top!
*Observe the position of the front and rear wheels
When cleaning an escalator,
ensure there is enough flat
step space for the T20i & that
none of the step risers can
collide with the T20i.
When cleaning, always trail
the cable in a safe manner
where it cannot be possible
to trip over or become
tangled up with it.

3. Operation

Rosemor International Ltd 2022 © 13
3.9 Cleaning the Escalator/Travelator
Now that the brakes are engaged and the
machine cannot roll forwards or backwards, you
are ready to begin the cleaning operation.
You may now start the travelator/escalator
running in the direction towards the T20i.
3.9.1 AutoStart Function Explained:
The T20i features the latest in industrial control
circuitry. This means that T20i can perform
many different functions with a single push of a
button. This makes the T20i a very user-friendly
machine to operate.
When in position and ready to clean (as outlined
above), the operator will simply press the
‘AutoStart’ button while holding the handle with
the other hand.
When this happens, it triggers a sequence of
instructions to the T20i:
1 – The cleaning head will automatically lower
down onto the escalator/travelator step treads.
2 – Then, the vacuum, detergent and brushes
will start.
T20i is now cleaning the step treads. Allow the
T20i enough time to thoroughly clean the treads.
This will depend on how dirty the treads are to
begin with. When you are satisfied with the
cleaning results, its time to move the T20i over
to clean the next area of the treads (if
applicable).
3.9.1 Moving T20i over/ending the cleaning cycle.
- Press the ‘AutoStop’ button.
This will trigger the same sequence as just
described, but in reverse order. The only
difference is the vacuum will remain on for ~15
seconds after the cleaning head has lifted in
order to catch any residual dirty detergent still
in the vacuum channel to reduce dripping.
Once the head has lifted clear of the treads, you
can bring the escalator/travelator to a stop.
Next, release the brakes and roll the T20i
backwards and clear of the escalator/travelator
treads and comb.
Line up the T20i in the next position over,
allowing a 1–2 inch (25-50mm) overlap of the
previous area cleaned.
Roll the T20i into position on the treads as
outlined in step 3.8 and continue to clean
following the steps in 3.9 again.
The travelator/escalator must
move towards the T20i during
cleaning. If the
travelator/escalator moves
away, The machine will not
clean or dry the treads
properly.

3.9.3 Overview of Button Panel
For general use and operation, it is
recommended to simply only use the ‘AutoStart’
and ‘AutoStop’ buttons. However, in certain use
cases and for advanced operators, you can
make use of some of the other button’s
functions too.
Here we outline the functions of each button and
give examples of their specific use outside of
regular cleaning. Please refer to the diagram
below.
11 – Cleaning Head Raise Button
- This button can be used for fine adjustment of
the cleaning head in the upwards direction.
12 – Vacuum on/off Button
- This button is used to switch on or off the
vacuum system. This could be useful if you
had a scenario in which you wanted to
saturate the area to be cleaned with
detergent before extracting it away.
13 – AutoStart Button
- As outlined above, this button triggers the
automatic cleaning sequence.
14 – Cleaning Head Lower Button
- This button can be used for fine adjustment of
the cleaning head in the downwards
direction.
15 – Detergent Pump Button
- This is used to turn off the detergent. This
could be useful if the area being cleaned is
already saturated and you want to remove as
much moisture as possible using the vacuum
and brushes only.
