A washing machine appliance may include a tub, a basket, and a retractable agitation element. The basket may be rotatably positioned within the tub. The retractable agitation element may be positioned within the basket. The retractable agitation element may define a rotation axis. The retractable agitation element may include a lower shaft, an upper shaft, and a resilient fin. The upper shaft may be slidably mounted on lower shaft in telescoping cooperation to move axially along the rotation axis. The resilient fin may be movably attached to the lower shaft apart from the upper shaft.

A laundry appliance includes a drum that is rotationally operable about a rotational axis within a tub. The rotational axis is oriented in a generally horizontal configuration. An impeller is rotationally operable within the drum about the rotational axis. A dual-rotor motor is coupled to the drum and the impeller for providing separate and independent rotation of the drum and impeller about the rotational axis. An inner rotor of the dual-rotor motor is coupled with the impeller and an outer rotor of the dual-rotor motor is coupled with the drum.
