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 after rinsing.
  
• 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.
