Thanks to the Oreck's ingenious top-fill design, the vacuum bag fills from the top, so it doesn't lose power pushing up yesterday's dirt. Its redesigned dirt-flow path assembly dramatically reduces the risk of clogging, and its 12" wide cleaning head covers a wider area and leaves no center dirt path. With its disposable, self-sealing inner bags and Saniseal® system, your whole family will breathe a lot easier. Other vacuums send a cloud of dust back into the room every time you turn them on. But not the Oreck.
