Handheld vacuums give extras such as revolving power brushed to beat dirt out of carpeting, as well as and variety of attachments and extensions designed specifically for nooks, crannies, ceilings and drapes. Additionally, cordless models come with a wall-mounted storage bracket that has a built in battery charger. Car vacuums, which plug into a car’s cigarette-lighter socket, look much like the cordless models, but they come without a wall storage bracket.
