A laundry appliance includes a cabinet having a rotating drum operably positioned therein for processing fabric. At least one transducer is positioned proximate the drum that provides an ultrasonic resonance that is directed into an interior chamber of the drum. The ultrasonic resonance is adapted to be directed into damp fabric being treated within the interior chamber. The ultrasonic resonance serves to modify water trapped within the damp fabric into a substantially gaseous form.

Methods and apparatuses consistent with the present invention provide for improved clothes rollover in automatic washer cycles using time-varying rotor oscillations. An automatic washer has a wash chamber with a central axis and a rotor being rotatable about the central axis. Items are loaded into the wash chamber. Wash liquid is supplied into the wash chamber. The rotor is oscillated about the central axis by time-varying oscillations.

A method to wash varying clothes load sizes with the same level of water is provided for a washer having a controller. A clothes load size setting signal is received in the controller. A mechanical duty cycle is set through the controller as a function of the clothes load size setting signal. A high-concentration wash step may be performed where a wash basket of the washer is spun at certain speeds while a highly concentrated wash bath solution is sprayed, extracted, and re-sprayed over the clothes load. On the completion of this high-concentration wash step, the washer is filled to a common water level regardless of the clothes load size setting signal. The clothes load is then processed through a wash cycle until completed.
