1. Introduction
Warnings
•This coffee machine is not to be used by children.
•Please take care when pouring the hot water into the basket as hot
water can burn your skin.
•Make sure both portafilter tabs are inserted into the main body before
brewing.
•NEVER try and operate the machine without the red piston seal in
place.
•The base of ceramic cups are very abrasive and will scratch the area of
the base under the spouts. For this reason we have supplied a
silicone mat to protect the area.
•Do not put any parts of the machine or the accessories for cleaning into
a dishwasher.
What it does do
•The Robot is capable of making real espresso coffee, those shots of
coffee can then be drank as espresso or used as the base for other
drinks such as Americano, Cappuccino, Latte etc.
•The Robot uses a commercial 58mm basket size
What is does not do
•The Robot does not have an internal heating element
•It does not steam milk
•The optional pressure gauge does not create the pressure – it merely
displays pressure that is exerted by you.
•The arms are designed to be loose and not stay in the upright position.
2. Inside the box
Inside the box you will find the following items
•The main body of the Robot with the arms and base assembled.
•1 portafilter without the spouts installed
•1 basket of your choice
•1 stainless steel tamper
•1 stainless steel dispersion disc
•1 silicone mat
•1 coffee measuring spoon (supplied with the pressurized basket only)
•Piston blanking plug and Teflon washer (if you have the Barista
version)
•1 pack of custom paper filters

Main part names and basic function
Here are the names of the components parts; all mention of these parts
during the remainder of this manual refers to these parts. For a detailed parts
list please see section 11
Almost all of the component parts are made from stainless steel. Certainly
any part of the machine that comes into contact with the water and/or coffee is
made from food grade stainless steel – one exception to that is the capillary
tube on the Barista Robot, which is made from an FDA approved material.
The other exception is the piston seal, which is made from an FDA approved
silicone.
Top Pin
– this is the main pivot for the Lever Arms
Main Body and base plate
– made from die cast Aluminium they are fixed
together by 2 screws

Lever arms
– These raise and lower the piston and are made from solid
stainless steel. They are designed to be loose and not stay in the upright
position.
The lever arms and the connecting rods are
an assembled unit. Do not attempt to undo
the screws marked with the red arrows.
They have been thread locked into place –
any attempt to undo them and you will most
probably strip the Hex indent.
Portafilter
– this holds the filter basket in place and is locked into the main
body
Spouts
– these attach to the portafilter is required
Basket
– this holds the ground coffee and the hot water
The Professional basket
The Pressurised basket
Screen
– this sits on top of the coffee grounds and slows down and
disperses the hot water across the coffee
Tamper
– this tamps (compresses) the coffee down inside the basket

Quick Start Guide
1. Add ground coffee to the basket. Approx. 10g-21g
2. Level the coffee and tamp the coffee using the tamper
3. Press the screen firmly on top of the coffee ensuring it is flat
4. Add water just off the boil and fill up to 5-8mm below the basket rim
5. Insert the portafilter into the machine and push the lever arms down
slowly and steadily
Paper filters may be used instead of the metal screen

4. Basic Overview of using the machine
The Robot is capable of making real espresso coffee as defined by the
Instituto Nazionale Espresso Italiano. http://www.espressoitaliano.org/
Modern espresso coffee can trace it’s origins back to the first lever coffee
machine produced by Gaggia in 1948 which used a spring and a piston to
force water at pressure through the coffee grounds. Such machines are
referred to as Traditional Lever Coffee Machines. (TLCM) The Robot uses
the exact same principal as a TLCM, except the power to drive the piston is
not provided by a spring but by the user.
The Robot does not have a boiler or a heating element, yet is still able to brew
coffee the same as a TLCM thanks to it’s oversized filter basket which
becomes a brewing chamber once it is filled with hot water.
By raising or lowering the lever arms the piston is raised or lowered into the
filter basket.
It is important to find a sturdy table or counter on which to use the machine,
trial and error will help you find a comfortable height to place the machine as
well. For example a table that is lower than usual will help you get your
shoulders over the machine and allow you to push the arms. Whereas a
counter that is higher will allow you to bend over and pull the arms down -
you may not get as much power in the shot but you will get a better look of the
process.
Having a counter that is level is important as a wonky counter may cause
under or over extraction in one area of the basket.
The Base Plate has a silicone gasket on the underside that prevents damage
to your counter top and helps it to grip the surface.
Assembling the portafilter
The handle that holds the filter basket and locks into the main body is called
the Portafilter (PF). One of the most important developments in espresso in
recent times has been the introduction of bottomless portafilters, (BPF) i.e.
portafilters without spouts.

Above left photos shows the Regular PF (top) and BPF (bottom). Above right
photos shows the o-ring seal in between the PF body and the Spout.
BPFs allow the user to get a close-up view of the coffee exiting the basket on
its journey into the cup. Not only does this look great, but it also gives you
instant feedback on what is happening inside the filter basket. If you are
unfamiliar with a BPF I highly recommend you do some research on these
valuable tools. With regards our Robot I would say some benefits are:
•When you see the first drops of coffee appear on the underside you
would say the coffee puck is fully infused
•You can tell if you have an even extraction – i.e. is the coffee exiting
the basket evenly all over or just on one side/area?
•Any pinhole sprays would indicate poor preparation
•More crema
•Possibly hotter coffee in the cup
The main drawback of using a BPF is the fact that the coffee will be in one
pour, if you want to make 2 single shots then you will need to install the plate,
this will split the coffee into 2 streams.
Since we are such big fans of using a BPF we have included our patented all-
in-one system that means you can use the PF as either a regular PF or as a
BPF. The PF assembly consists of the PF with the Spouts combined. The
Spouts are press-fit held in place with the help of a silicone o-ring. On first
installation of the spouts into the PF body it may be necessary to use some
silicone lubricant (such as Dow 111) or some water.
The spout should be fairly tight in the PF body, if they are too loose, clean the
o-ring as there may be too much lubricant on them or replace the o-ring.
The basket is simply placed into the PF; there is no spring clip to
hold it in place.

Inserting and removing the portafilter
Always have the arms up as high as they can go when inserting or removing
the portafilter.
When inserting the portafilter you
must lift it up first and then slide it
over to the right as per the red
arrows.
If you try and insert it like on a
conventional machine, such as
shown by the orange arrow, it will
not be easy.
To familiarize yourself with locking
in the portafilter into the main body,
you can practice without a basket in
place.
To remove the portafilter turn to the
left. Then break the seal by tipping
the end of the handle down whilst
leaving the main body where it is
as if it were a pivot point.
That will break the seal and then
you can remove the portafilter and
basket together.
If you simply turn the handle left and
lower the portafilter there is a good
chance the basket will be stuck to the
piston.
So for this reason we advise the tipping
the handle method above.

The filter screen and filter papers
The filter screen allows you to pour hot water onto the tamped bed of coffee
without creating a mess of coffee and water.
The screen has been designed in such a way that it holds back and
distributes the water yet is thin and will not act as a heat-sink for the hot
water.
The screen is therefore quite fragile but with some care and attention it will
last a while.
.
We recommend firmly pressing the screen in place, and ensuring that it is
level so that the centre pin is straight.
The photo on the left is an example
of a correctly placed screen.
The photo on the right shows an
incorrectly positioned screen
that is not level and therefore
has the pin off centre.
If one were to press the levers
down fully it would almost
certainly result in a damaged
screen.
