The Subminimal NanoFoamer GO is a compact, USB-C rechargeable handheld milk frother that produces latte art-quality microfoam using Subminimal's patented NanoFoamer technology, spinning at up to 5,300 RPM submerged. It ships with three interchangeable impellers for frothing, mixing, and whisking, plus a color-matched carry case. The NanoFoamer GO is available in ten colors.
The NanoFoamer GO uses Subminimal's patented impeller-and-screen system to produce the fine-bubbled, liquid-velvet texture that commercial steam wands create. At 5,300 RPM on high and 4,200 RPM on low, the submerged motor drives milk through the included Superfine NanoScreen, breaking bubbles down to the size that lets latte art hold its shape. Two speed settings let you dial between a dense microfoam for flat whites and a lighter, airier foam for matcha cold-foam or cappuccinos.
The NanoFoamer GO ships with a NanoFoam Screen impeller, a Mixing impeller, and a Whisk/Froth impeller. Swapping between them takes seconds, which means the same device that textures your morning milk can blend a protein shake or whisk cream without a second appliance on the counter. Each impeller is made from food-safe POM plastic; the NanoScreen mesh and shaft are Stainless Steel 304.
At 76 g and 25 x 25 x 205 mm, the NanoFoamer GO fits a jacket pocket. IPX-4 splash resistance means the impeller rinses freely under running water and incidental splashes on the handle are not a concern. Subminimal designs every component to be serviced individually rather than replaced as a unit: the shaft, screen, and impellers are all available as separate spare parts. USB-C charging means no proprietary cable to track down.

The NanoFoamer GO suits home baristas and travelers who want cafe-quality microfoam without a steam wand, and anyone who wants a single compact tool that can also mix protein shakes or whisk cream. The carry case makes it practical for office kitchens, hotel rooms, or anywhere counter space is limited.
The NanoFoamer GO is a handheld, single-serving device and is not suited to frothing large volumes of milk in one pass or to continuous commercial use. It does not heat milk; a separate heating method is required. Its IPX-4 rating covers splashes and rinsing only; the device is not rated for full submersion.
The NanoFoamer GO is a more compact version of the NanoFoamer, with slightly smaller diameter impellers that allow it to fit in a carry case. Despite the smaller size, the GO runs at the same high-end RPM range and delivers comparable microfoam quality. The included carry case is unique to the GO and makes it the more portable option of the two.
The NanoFoamer GO ships with the Superfine NanoScreen, which is described as the most popular size in the NanoScreen range. Replacement NanoScreen kits for the GO are available separately if the screen needs to be replaced over time.
Yes. The NanoFoamer GO carries an IPX-4 water-resistance rating, meaning it withstands splashes from any direction. Rinsing the impeller by spinning it under running water is recommended; incidental splashes on the handle are also fine. The device is not rated for full submersion.
Each NanoFoamer GO ships with the frother itself, a color-matched carry case, a NanoFoam Screen impeller, a Mixing impeller, and a Whisk/Froth impeller. The carry case dimensions are 53 x 152 x 32 mm and the total weight including the case is 151 g.
The NanoFoamer GO impellers are made from food-safe POM (polyoxymethylene). The NanoScreen mesh, shaft, and cap are all Stainless Steel 304. These materials are chosen for food contact safety and durability in a wet environment.
