Our test is based on the standard AS/NZS 2040:1998, and was completed using machines filled with 3.5kg loads.
Overall score is based on:
Dirt removal (50%): Calculated according to a formula in the
standard, which reduces the score in proportion to the variability of
dirt removal over a range of test swatches in the wash load.
Water efficiency (10%): Based on the amount of water used in the
whole cycle, per kg of clothes.
Rinse performance (20%): Based on the amount of detergent residues
Spin efficiency (10%): Calculated from the amount of water remaining
(per kg) in the damp clothes.
Gentleness (10%): Calculated from the amount of wear on easily frayed
squares of cloth.
