If it is cheaper to outsource with other brands, then there's no point unless the said brand actually have a more involved design process. You'd never find Miele for example giving over their design to other brands. Bissell aren't exactly the first name in dry cleaning floor care. They propose that they were the first to make carpet sweepers but they're not upright vacs. In my mind Bissell is more known for its shampooer and wash vacuums, let alone the Chinese brand upright washers.
