The K155 Office Pro, with its 1,400-watt power rating, emphasizes energy efficiency, making it a practical choice for office environments where continuous use is common. Its compact design guarantees it fits seamlessly into shared spaces without compromising functionality. In contrast, the K-Cafe SMART, while also energy-efficient, integrates a sleek, modern aesthetic with its black exterior and built-in milk frother, catering to home users seeking versatility. Both models prioritize space-saving designs, but the K155's fully automatic operation and transport-friendly features make it ideal for workplaces, whereas the K-Cafe SMART's advanced connectivity and frothing capabilities appeal to coffee enthusiasts.

Features and Benefits

The Keurig K155 and K-Cafe SMART models feature WiFi-enabled BrewID technology, which customizes brew settings and recommends ideal beverage profiles for enhanced flavor. MultiStream Technology guarantees even saturation of grounds, delivering consistent aroma and taste, while customizable strength and temperature settings cater to individual preferences. Additionally, the K-Cafe SMART includes a versatile milk frother with cold and hot settings, expanding beverage options to include lattes, cappuccinos, and iced drinks.

Wifi-Enabled Brewid Technology

By integrating WiFi-enabled BrewID technology, the Keurig K-Cafe SMART elevates the coffee brewing experience through advanced customization and connectivity. This smart connectivity allows the brewer to recognize K-Cup pods automatically, tailoring brew settings for ideal flavor extraction. Users can access personalized recommendations, including SIGNATURE BREW settings, via the Keurig app, which also activates Barista Mode for step-by-step beverage instructions. The remote brewing feature enables users to schedule or initiate brews from their smartphones, ensuring a fresh cup is ready upon demand. Compared to traditional brewers, the K-Cafe SMART's BrewID technology enhances convenience and precision, offering a seamless integration of smart home functionality. This innovation bridges the gap between manual customization and automated precision, making it a standout feature for tech-savvy coffee enthusiasts.

Multistream Technology for Full Flavor

Multistream Technology revolutionizes the coffee brewing process by guaranteeing ideal saturation of K-Cup pod grounds, delivering a consistently rich and aromatic cup. This advanced system employs multiple streams of water to evenly penetrate the coffee grounds, optimizing flavor extraction and aroma enhancement. Unlike traditional single-stream methods, which can result in uneven saturation and inconsistent taste, Multistream Technology guarantees every particle is uniformly exposed to water, releasing the full potential of the coffee. This precision engineering not only enhances the depth of flavor but also preserves the nuanced notes and aromatic qualities of the brew. By maximizing the interaction between water and grounds, this technology elevates the coffee experience, making it a standout feature in both the Keurig K155 and K-Cafe SMART models.

Customizable Strength and Temperature Settings

With customizable strength and temperature settings, the Keurig K155 and K-Cafe SMART models empower users to tailor their brewing experience to precise preferences, guaranteeing ideal flavor and satisfaction. The K155 offers programmable temperature control, allowing adjustments between 187°F and 192°F, while the K-Cafe SMART leverages BrewID technology to auto-adjust settings based on the K-Cup pod. Both models cater to diverse strength preferences, enabling users to select from light, medium, or bold brews. The K-Cafe SMART further enhances customization with two coffee shot sizes, perfect for crafting specialty drinks. These features, combined with MultiStream Technology, guarantee peak extraction and consistency. Whether prioritizing temperature control or strength preferences, both models deliver precision and versatility, making them standout choices for discerning coffee enthusiasts.

Includes Milk Frother With Cold Setting

The Keurig K-Cafe SMART distinguishes itself with an integrated milk frother that offers both hot and cold frothing capabilities, catering to a wide range of beverage preferences. The cold froth setting is particularly innovative, enabling users to create creamy, chilled toppings for iced coffees, lattes, and cold froth recipes like iced macchiatos or nitro-style beverages. The frother features three speed settings, ensuring ideal texture for various milk types, including dairy alternatives. Its design prioritizes ease of use, with detachable components for straightforward frother maintenance tips, such as regular cleaning to prevent residue buildup. Compared to standalone frothers, the K-Cafe SMART's integrated system saves counter space while delivering professional-quality results. This feature enhances versatility, making it a standout choice for coffee enthusiasts seeking both functionality and convenience in a single brewer.
