Barista vs Regular

We always recommend Regular Robot for home-user, but it's completely your choice. The Barista Robot with the gauge system is also a bit more involved whereas the Regular Robot is bullet proof. 

The Barista Robot has a built in pressure gauge which will display the pressure from the basket during extraction. The flexible tube and fittings are all made in the EU. These items are not under warranty.

 - The pressure gauge displays the pressure that you exert with the arms. It does not create the pressure.

 - If the pressure gauge reads no or low pressure you will need to pay attention to shot time and therefore grind setting, force applied and coffee dose. Please find more on the 'Brewing Tips'

- We recommend a pressure range of 4-8 bar.

You do not need a pressure gauge to make good coffee, it will however give you an idea when you first use it how hard you need to push down to get the required pressure. Without a pressure gauge you can simply place a bathroom scale underneath and aim for 16-18kg which will put you in the right area. Here is a guide of the Robot weight/pressure and the figures are approximations:

But don’t get hung up on numbers, the visual indicators and taste are just as if not more important. After a dozen or so uses you will get a feeling of how much force they need to exact and not read the gauge anymore.

Cautions when using Barista Robot

The position of the tube

The pressure gauge system is very reliable as long as the tube does not move out of position. If it does move you can easily flick it back to the correct orientation.

If the metal sleeve and the flexible tube is being pinched, damaged or broken, please purchase the spare parts. These items are not under warranty.

Pressure gauge stop showing the correct value or water gets inside

The pressure gauge is quite a delicate instrument.

Paul always align the pressure gauge horizontally with the bracket on each Barista Robot. If it is not, the gauge screws may come loose. A slight turn the gauge screws in from the front clockwise will tighten it back up again.

To remove the pressure gauge front plastic, use a flat blade in the joint where the plastic meets the chrome of the pressure gauge body. It just pops out and clips in. Then you can remove the water, reset the pin etc from inside. 

Pressure gauge registers very little pressure or does not work

 - Push the levers down with more force.

- If the coffee is ground too coarse or is stale, the coffee will offer little resistance and you will not be able to build up pressure. Please visit 'Brewing Tips' for more information.

 - Check for leaks in the hydraulic circuit, you would see water drops or hear air hissing from somewhere along the tube. If you notice the metal sleeve and the flexible tube is being pinched, damaged or broken, please purchase the spare parts. These items are not under warranty.

 - It is unlikely but possible the pressure gauge is broken. Convert the Barista Robot to Regular Robot by using the piston plug and telfon washer provided, then contact us via Contact Us Form.


The pressure gauge is permanently fixed to the bracket and then to the female fitting on the back. A mesh filter is then placed between that and the Parker Legris elbow fitting on the back. The hydraulic connection to the piston is then made with a 4mm OD FDA approved Parker Legris flexible tube.

Please do not tamper or try and remove the pressure gauge. The gauge itself has been locked in place with the 13mm hexagonal female fitting on the back. You may remove the elbow fitting on the back and inspect for blockages if required.

To remove the tube from these fittings you must push down the locking collar whilst at the same time pulling the pipe out of the fitting.
