One variation of a mixing system includes: a container configured to store consumable beverages; a lid; and a mixer. The lid is configured to transiently couple to the container and includes: a housing; a mixer receptacle; a set of user controls arranged on an outer face of the lid; a set of electronics arranged within the housing and including a motor, a controller configured to actuate the motor responsive to selection of the set of user controls, and a power supply configured to supply power to the motor and the controller; and a set of supports arranged between the motor and walls of the housing and configured to absorb energy output by the motor. The mixer includes: a connector section configured to engage the mixer receptacle to couple the mixer to the motor; and a mixing section configured to mix ingredients in the container responsive to actuation of the motor.

An insert assembly for a foam generating device includes a first insert and a second insert with a channel defined therethrough. Inserts may be formed by two shell halves that are coupleable to one another to define the channel. A plurality of ribs extends along an interior surface of the channel. Pad structures defined by porous media are provided in the channel and gripped by the plurality of ribs. The pads receive cleaning solution passing through the channel and cause foam to be generated by breaking-up the cleaning solution and agitating. The ribs may be arranged horizontally relative to a longitudinal axis of the insert assembly and retain the pads within the device. Inserts may be arranged in series along a longitudinal axis of the foam generating device with the pad structures arranged within the channel.
