Introducing the ARO Orbit™, a premium spirographic espresso distribution tool. We've optimized every aspect of this tool — from meticulously engineered gear ratios and pin placements to a mechanism that spins with the ease of a finger. Elevate your espresso with unmatched consistency in every pull. Perfectly fluffed and distributed baskets of espresso are just a few spins away.

Here's a quick geometry lesson: Hypotrochoids and epitrochoids are curves defined by tracing a point attached to a circle that's rolling along the inside or outside of a fixed circle, respectively. Spirographs use this concept to create dazzling geometric patterns.

The ARO Orbit™ utilizes 10x, 0.25mm diameter pins to trace dozens of hypotrochoids and epitrochoids through the clumpy espresso in your 58mm or 54mm portafilter basket. This mechanical motion distributes and fluffs the grounds in seconds, and ensures consistency no matter how early in the morning it is.

The ARO Orbit™ uses a novel gear design that mixes, distributes, and fluffs the grounds in your portafilter in as little as four spins. There are three separate gears that all work together in an optimized fashion. The gear with short arms (a.k.a The Scrambler) bounces the pins back and forth across the basket to scramble and mix the grounds. The gear with the extended arms (a.k.a The Sweeper) whips around the entire basket slicing every clump in its path. The small gear (a.k.a The Edge Dancer) pushes and pulls the grounds closest to the edge into the path of the large gears to ensure 100% basket coverage and a perfect distribution.

The tool also uses features the ability to effortlessly adjust the needle length to fit virtually any 58mm portafilter basket. Simply rotate the adjustment sleeve and lock it in place for a customized fit on your favorite portafilter basket.

We offer four unique finishes to make your espresso station stand out amongst the pack. Choose between textured, carbon fiber, geometric, or galaxy and pick up an ARO Orbit™ today!

To use the tool:

1. Install 10 pins by inserting them into the holes in the gears. If a pin hole is hard to reach, try rotating the tool a bit so that the gears move into a new position. You can also remove the adjustment sleeve to get better access to the pin holes. The deeper you insert the pins, the tighter they will grab. Be careful here and take your time. Our pins come with a dulled head, but they are still pokey!

2. With your portafilter basket empty, place the tool inside of the basket to determine if you need to adjust the pin height on the tool. Holding the tool under a bright light will help significantly. If an adjustment is needed, hold the jam nut and rotate the adjustment sleeve until you reach your desired height. Then tighten the jam nut against the adjustment sleeve to lock its position.

3. Fill your portafilter with espresso grounds and place the tool on top. You will notice a white circle around one of the pin holes. The tool can be rotated until the white circle is closest to the edge of the tool. In this configuration, the pins are furthest away from the edges and the tool is easier to place on your portafilter without a pin getting caught outside the basket.

4. Spin the tool 3-4 times. Don't overdo it, and don't spin it too fast. After the final spin, hold the tool on top of the portafilter and give the portafilter a few light taps on the counter to settle the grounds. Give the tool one more final slow spin and gently remove it from the portafilter basket

4. Place the tool in its stand, tamp your grounds, and go brew some espresso.
