Compatibility Note - Only compatible with 58mm baskets, and straight walled baskets. Manual WDT is always a dance with human error - stir too fast, and centrifugal force throws the grounds to the edges; stir too shallow, and hidden pockets remain. Autospin completely automates the choreography of puck prep, turning a highly variable ritual into a mechanical guarantee of ideal density. 12-Needle Bidirectional Orbit Twelve ultra-fine 0.3mm needles sweep through the coffee bed on a fixed planetary path, reaching down to a deep 22mm depth. Unlike manual stirring, the system automatically alternates between clockwise and counter-clockwise cycles, eliminating clumps and peaks without pushing the grounds toward the walls of your basket. Contact-Activated Automation No buttons, no friction. The moment the tool makes contact with your portafilter, the motorized cycle begins automatically; the moment you lift it, it stops. An open-top architectural frame lets you watch the planetary movement in real-time, giving you an at-a-glance look at your distribution. Four-Point Support Geometry The wide, four-legged chassis is engineered to self-center on standard 58mm straight-walled baskets. This structural alignment keeps the tool perfectly level during operation, while the outer legs double as a protective shield for the needles when the device is sitting on your counter. Fits 58mm baskets only - does not support 3-lug portafilters or curved-walled baskets. 2,000-Cycle Energy Cell A compact 500mAh lithium battery is hidden inside the matte unibody housing, recharging fully via USB-C in just 1.5 hours. It packs enough power to run through more than 2,000 preparation cycles on a single charge. We recommend charging every three months; charging cable not included.
