— it is customary to classify handheld household vacuum cleaners as specialized automotive models (see the relevant paragraph) that can operate from their battery and/or from a car cigarette lighter (see "Power supply"). It is these types of power supplies that allow you to easily use a vacuum cleaner for cleaning car interiors. At the same time, the specific specialization of units of this type can be different: some work only from the cigarette lighter and are designed exclusively for cars, while others can be used in everyday life. Among the latter, there are even models with the ability to connect to a conventional outlet, but this possibility is necessarily combined with a built-in battery.
