Abstract: Various illustrative systems, devices, and methods for beverage machines are provided. In one exemplary implementation, a system includes a portafilter and a plurality of baskets. The portafilter is configured to be removably coupled to an espresso machine. The plurality of baskets each define a filter, each is removably receivable in the portafilter, and each is configured to hold coffee grounds. The plurality of baskets including a first basket, a second basket, and a third basket. The third basket has a volume that is about 105 mL to 135 mL. The third basket is configured to permit brewing of a beverage using pressurized and unpressurized brewing methods.

Abstract: Various illustrative systems, devices, and methods for beverage machines are provided. In one exemplary implementation, a system includes a housing, a grinder, a portafilter, a filter basket, and a tamp. The grinder is disposed within the housing. The portafilter is removably coupled to the housing. The filter basket is configured to be removably disposed within the portafilter for receiving coffee grounds. The tamp is configured to be disposed within the housing and has a tamp head, a tamp body, and a spring.

Abstract: Various illustrative systems, devices, and methods for beverage machines are provided. In one exemplary implementation, a system includes a portafilter, a filter basket, a funnel, and a tamp. The portafilter is configured to be removably coupled to a housing of a beverage machine. The filter basket is configured to be removably disposed within the portafilter for receiving coffee grounds. The funnel is configured to be removably mounted on the portafilter and has a passageway configured to receive the coffee grounds therein and to direct the coffee grounds into the filter basket. The tamp is slidably insertable into the passageway of the funnel and configured to advance through the funnel to press the coffee grounds in the filter basket.

Abstract: Various illustrative systems, devices, and methods for beverage machines (e.g., drip coffee machines, espresso machines, etc.) are provided. In an exemplary implementation, an espresso machine is configured to brew and dispense espresso. In an exemplary implementation, the espresso machine is configured to determine a recommended coffee bean grind size for a beverage, e.g., an espresso or a sprover-style drink, selected by a user and to provide the recommended coffee bean grind size to the user.

Abstract: Various illustrative systems, devices, and methods for beverage machines are provided. In one exemplary implementation, a system is provided that includes a milk receptacle and a housing. A whisk is configured to agitate the milk held by the milk receptacle. The whisk includes a magnet. The housing has a steam frother arm with a fluid flow path configured to deliver steam into the milk receptacle. The housing also has a motor configured to drive the whisk. The motor has a motor magnet configured to magnetically interact with the magnet of the milk receptacle such that rotation of the motor magnet drives rotation of the whisk to agitate the milk held by the milk receptacle.

Abstract: A rotatable agitator is used in a surface clearing head of a surface cleaning apparatus. The agitator is coupled to the cleaning head at least partially within an agitator chamber and is rotated about a pivot axis. The agitator includes an elongated agitator body and a hair migration portion. The hair migration portion includes a continuous row of bristles and a sidewall. The continuous row of bristles and sidewall are at least partially revolved around and extend along at least a portion of the pivot axis from one of a collection area or a first end region of the agitator and either another collection area or a second end region of the agitator. The sidewall extends substantially parallel to the continuous row of bristles within the hair migration portion. The continuous row of bristles and sidewall are configured to reduce hair from becoming entangled in the bristles and to migrate hair towards the collection area or the first end region of the agitator.
