After months of research regarding the cleaning ability of high efficiency washers, we selected the LG WT7155CW.  We chose the agitator model because many of my work clothes are heavily soiled.  The large capacity is great for large bed linens.  Adding extra water is simple compared to other available models.  The heavy duty mode is equal to the cleaning effectiveness of the normal mode on the washer we replaced.  The high speed spin cycle leaves very little water in the clothes and speeds drying time.
