A laundry apparatus comprising: a tub defining a fluid containment envelope; a drum positioned within the fluid containment envelope of the tub and rotatable relative to the tub about a primary rotation axis, the drum comprising a laundry-receiving portion for receiving one or more articles of laundry; a control unit; a motor coupled to the tub, wherein the motor is communicatively coupled to the control unit and operatively coupled to the drum to cause rotation of the drum, wherein the motor is isolated from fluid within the fluid containment envelope; one or more load imbalance sensors communicatively coupled to the control unit and configured to output a load imbalance signal to the control unit, the load imbalance signal being indicative of a load imbalance within the drum; and a dynamic balancing assembly communicatively coupled to the control unit, the dynamic balancing assembly comprising: an orbital balancing passage arranged concentrically around the motor; a first counterweight device positioned within the orbital balancing passage and responsive to the control unit, wherein the control unit controllably moves the first counterweight device along the orbital balancing passage to adjust an angular position of the first counterweight device around the primary rotation axis to counteract a detected load imbalance in the drum; and a second counterweight device positioned within the orbital balancing passage and responsive to the control unit, wherein the control unit controllably moves the second counterweight device along the orbital balancing passage to adjust an angular position of the second counterweight device around the primary rotation axis to counteract the detected load imbalance in the drum; characterized in that, a cross-sectional plane passing through the laundry apparatus at a position orthogonal to the primary rotation axis passes through the dynamic balancing assembly, the motor, and the fluid containment envelope of the tub, and in that at least a surface of the tub and a surface of the motor are substantially flush with one another. a tub defining a fluid containment envelope;
