A rinse arrangement for cleaning an interior volume of a tank, the arrangement comprising: a rinse nozzle (200) having a rotary head (216) via which rinse fluid is sprayed as the head rotates about a rinse nozzle axis A; a telescopic mechanism (218, 220) attached to the rotary head movable between a retracted position and an extended position along the rinse nozzle axis A; a biasing means (222) to bias the telescopic mechanism to the retracted position; means (300) for applying rinse fluid to the rinse nozzle alternately at a low pressure and a high pressure, the low pressure the fluid to spray from the rotary head and causing rotation of the rotary head around the axis due to the force of the spraying of the fluid, but the low pressure being insufficient to overcome the bias, and the high pressure overcoming the bias and causing the telescopic mechanism to move to the extended position and to cause rotation of the rotary head around the axis due to the force of the spraying of the fluid.
