What type of water unit can improve cleaning and reduce detergent usage?

A water softener unit is designed to improve the effectiveness of cleaning by removing minerals such as calcium and magnesium from hard water. These minerals can cause soap scum and reduce the effectiveness of detergents, leading to a need for more detergent and potentially less effective cleaning. By softening the water, a water softener allows detergents to work more efficiently, improving the cleaning process and often enabling the use of less product.

In contrast, high-pressure water units primarily focus on the force of the water rather than the quality of the water itself and may not directly impact detergent usage. Cold water units can clean effectively, but they might not dissolve detergents as efficiently as soft water would. Hot water units can enhance cleaning by helping to dissolve soils and oils, but they don't necessarily reduce detergent needs like a water softener does. Thus, using a water softener can lead to more effective cleaning and less dependency on detergents.
