Bosch is an absolute powerhouse of a corporation with a wide expanse of companies under its umbrella. You might know the Bosch brand for its high-quality power tools, but it's also invested in several other markets. Bosch's washing machines are ranked among the quietest options available according to Consumer Reports, and the company also makes some pretty impressive air conditioner units. Bosch also owns several different companies, four of which offer broad international coverage, and over a dozen others that specialize in regional distribution within either North America or Europe. Different brands specialize in different types of machines.
