58mm filter baskets The same size as professional semi-automatic machines. Our baskets are extremely high quality, they are made by the same factory that makes all the best baskets in the world.
Bottomless is best For best results we recommend using the portafilter without the spouts - but when using the pressurised basket it is best to use with the spouts attached.
All-in-one portafilter Cafelat famous (patented) All-in-on portafilter that allowing you either have a naked (bottomless) portafilter or combine it with the portafilter spouts then make it as a regular portafilter.
Stainless Steel Tamper 1 piece stainless steel tamper designed and machined to precisely fit snugly in the basket and has tapered side walls to prevent ground being sucked back when you lift the tamper.
Pressure gauge Our Patent Pending system takes the pressure reading from inside the basket. Add to that the manual pressing of the lever arms, it enables you to manipulate pre-infusion, flow and pressure in real-time to get the best from your coffee.
Extraction pressure Ignore the magic 9 bar, that figure originally referred to the pump output pressure of a Faema E61 machine, when in actual fact the pressure at the group will be lower, maybe even 1-2 bar lower. Traditional lever machines (as measured by us) typically extract at 6-7 bars, and since the basket and piston on the Robot are the same size, we suggest you initially aim for 6-7 bars as well and adjust as preferred.
Temperature management The Robot is clearly not going to give you a La Marzocco type flat temperature profile. But water off the boil poured into a gently pre-heated basket will yield approx 95°C water, and will give you up to 88 °C coffee output from the basket.
Extraction ratios Certainly a 2:1 ratio of beverage mass to ground coffee is possible i.e. a 16g coffee dose can easily yield a 32g beverage weight. You can increase the beverage weight up to 40-45g if needed.
It's a lever machine Lever machines can be very forgiving thanks to their gentle pre-infusion and the soft ramp up to full pressure.
